I want to write a module where on a click of a button the camera opens and I can click and capture an image. If I don't like the image I can delete it and click one more image and then select the image and it should return back and display that image in the activity.

Solution 1

Here's an example activity that will launch the camera app and then retrieve the image and display it.

package edu.gvsu.cis.masl.camerademo;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class MyCameraActivity extends Activity
{
    private static final int CAMERA_REQUEST = 1888; 
    private ImageView imageView;
    private static final int MY_CAMERA_PERMISSION_CODE = 100;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        this.imageView = (ImageView)this.findViewById(R.id.imageView1);
        Button photoButton = (Button) this.findViewById(R.id.button1);
        photoButton.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
                {
                    requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_PERMISSION_CODE);
                }
                else
                {
                    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);
                } 
            }
        });
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
    {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == MY_CAMERA_PERMISSION_CODE)
        {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }
            else
            {
                Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
            }
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {  
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK)
        {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
        }  
    } 
}

Note that the camera app itself gives you the ability to review/retake the image, and once an image is accepted, the activity displays it.

Here is the layout that the above activity uses. It is simply a LinearLayout containing a Button with id button1 and an ImageView with id imageview1:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/photo"></Button>
    <ImageView android:id="@+id/imageView1" android:layout_height="wrap_content" android:src="@drawable/icon" android:layout_width="wrap_content"></ImageView>

</LinearLayout>

And one final detail, be sure to add:

<uses-feature android:name="android.hardware.camera"></uses-feature> 

and if camera is optional to your app functionality. make sure to set require to false in the permission. like this

<uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature>

to your manifest.xml.

Update (2020)

Google has added a new ActivityResultRegistry API that "lets you handle the startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows" - source.

The API was added in androidx.activity 1.2.0-alpha02 and androidx.fragment 1.3.0-alpha02.

So you are now able to do something like:

val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { success: Boolean ->
    if (success) {
        // The image was saved into the given Uri -> do something with it
    }
}

val imageUri: Uri = ...
button.setOnClickListener {
    takePicture.launch(imageUri)
}

Take a look at the documentation to learn how to use the new Activity result API: https://developer.android.com/training/basics/intents/result#kotlin

There are many built-in ActivityResultContracts that allow you to do different things like pick contacts, request permissions, take pictures or take videos. You are probably interested in the ActivityResultContracts.TakePicture shown above.

Note that androidx.fragment 1.3.0-alpha04 deprecates the startActivityForResult() + onActivityResult() and requestPermissions() + onRequestPermissionsResult() APIs on Fragment. Hence it seems that ActivityResultContracts is the new way to do things from now on.


Original answer (2015)

It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.

Request this permission on the AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

On your Activity, start by defining this:

static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;

Then fire this Intent in an onClick:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
    // Create the File where the photo should go
    File photoFile = null;
    try {
        photoFile = createImageFile();
    } catch (IOException ex) {
        // Error occurred while creating the File
        Log.i(TAG, "IOException");
    }
    // Continue only if the File was successfully created
    if (photoFile != null) {
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
        startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
    }
}

Add the following support method:

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

Then receive the result:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        try {
            mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
            mImageView.setImageBitmap(mImageBitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.

Solution 4

I know it's a quite old thread, but all these solutions are not completed and don't work on some devices when user rotates camera because data in onActivityResult is null. So here is solution which I have tested on lots of devices and haven't faced any problem so far.

First declare your Uri variable in your activity:

private Uri uriFilePath;

Then create your temporary folder for storing captured image and make intent for capturing image by camera:

PackageManager packageManager = getActivity().getPackageManager();
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
    File mainDirectory = new File(Environment.getExternalStorageDirectory(), "MyFolder/tmp");
         if (!mainDirectory.exists())
             mainDirectory.mkdirs();

          Calendar calendar = Calendar.getInstance();

          uriFilePath = Uri.fromFile(new File(mainDirectory, "IMG_" + calendar.getTimeInMillis()));
          intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          intent.putExtra(MediaStore.EXTRA_OUTPUT, uriFilePath);
          startActivityForResult(intent, 1);
}

And now here comes one of the most important things, you have to save your uriFilePath in onSaveInstanceState, because if you didn't do that and user rotated his device while using camera, your uri would be null.

@Override
protected void onSaveInstanceState(Bundle outState) {
     if (uriFilePath != null)
         outState.putString("uri_file_path", uriFilePath.toString());
     super.onSaveInstanceState(outState);
}

After that you should always recover your uri in your onCreate method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
         if (uriFilePath == null && savedInstanceState.getString("uri_file_path") != null) {
             uriFilePath = Uri.parse(savedInstanceState.getString("uri_file_path"));
         }
    } 
}

And here comes last part to get your Uri in onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
    if (resultCode == RESULT_OK) {
         if (requestCode == 1) {
            String filePath = uriFilePath.getPath(); // Here is path of your captured image, so you can create bitmap from it, etc.
         }
    }
 }

P.S. Don't forget to add permissions for Camera and Ext. storage writing to your Manifest.

Solution 5

Here you can open camera or gallery and set the selected image into imageview

private static final String IMAGE_DIRECTORY = "/YourDirectName";
private Context mContext;
private CircleImageView circleImageView;  // imageview
private int GALLERY = 1, CAMERA = 2;

Add permissions in manifest

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="ANDROID.PERMISSION.READ_EXTERNAL_STORAGE" />

In onCreate()

    requestMultiplePermissions(); // check permission 

    circleImageView = findViewById(R.id.profile_image);
    circleImageView.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showPictureDialog();
        }
    });

Show options dialog box (to select image from camera or gallery)

private void showPictureDialog() {
    AlertDialog.Builder pictureDialog = new AlertDialog.Builder(this);
    pictureDialog.setTitle("Select Action");
    String[] pictureDialogItems = {"Select photo from gallery", "Capture photo from camera"};
    pictureDialog.setItems(pictureDialogItems,
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    switch (which) {
                        case 0:
                            choosePhotoFromGallary();
                            break;
                        case 1:
                            takePhotoFromCamera();
                            break;
                    }
                }
            });
    pictureDialog.show();
}

Get photo from Gallery

public void choosePhotoFromGallary() {
    Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(galleryIntent, GALLERY);
}

Get photo from Camera

private void takePhotoFromCamera() {
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, CAMERA);
}

Once the image is get selected or captured then ,

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == this.RESULT_CANCELED) {
        return;
    }
    if (requestCode == GALLERY) {
        if (data != null) {
            Uri contentURI = data.getData();
            try {
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), contentURI);
                String path = saveImage(bitmap);
                Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
                circleImageView.setImageBitmap(bitmap);

            } catch (IOException e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), "Failed!", Toast.LENGTH_SHORT).show();
            }
        }

    } else if (requestCode == CAMERA) {
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        circleImageView.setImageBitmap(thumbnail);
        saveImage(thumbnail);
        Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
    }
}

Now its time to store the picture

public String saveImage(Bitmap myBitmap) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
    File wallpaperDirectory = new File(Environment.getExternalStorageDirectory() + IMAGE_DIRECTORY);
    if (!wallpaperDirectory.exists()) {  // have the object build the directory structure, if needed.
        wallpaperDirectory.mkdirs();
    }

    try {
        File f = new File(wallpaperDirectory, Calendar.getInstance().getTimeInMillis() + ".jpg");
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        MediaScannerConnection.scanFile(this,
                new String[]{f.getPath()},
                new String[]{"image/jpeg"}, null);
        fo.close();
        Log.d("TAG", "File Saved::---&gt;" + f.getAbsolutePath());

        return f.getAbsolutePath();
    } catch (IOException e1) {
        e1.printStackTrace();
    }
    return "";
}

Request permission

You need to read up about the Camera. (I think to do what you want, you'd have to save the current image to your app, do the select/delete there, and then recall the camera to try again, rather than doing the retry directly inside the camera.)

Solution 7

Here is code I have used for Capturing and Saving Camera Image then display it to imageview. You can use according to your need.

You have to save Camera image to specific location then fetch from that location then convert it to byte-array.

Here is method for opening capturing camera image activity.

private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;

private void captureCameraImage() {
        Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File f = new File(Environment.getExternalStorageDirectory(), "POST_IMAGE.jpg");
        chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
        imageToUploadUri = Uri.fromFile(f);
        startActivityForResult(chooserIntent, CAMERA_PHOTO);
    }

then your onActivityResult() method should be like this.

@Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == CAMERA_PHOTO && resultCode == Activity.RESULT_OK) {
                if(imageToUploadUri != null){
                    Uri selectedImage = imageToUploadUri;
                    getContentResolver().notifyChange(selectedImage, null);
                    Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
                    if(reducedSizeBitmap != null){
                        ImgPhoto.setImageBitmap(reducedSizeBitmap);
                        Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
                          uploadImageButton.setVisibility(View.VISIBLE);                
                    }else{
                        Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                    }
                }else{
                    Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                }
            } 
        }

Here is getBitmap() method used in onActivityResult(). I have done all performance improvement that can be possible while getting camera capture image bitmap.

private Bitmap getBitmap(String path) {

        Uri uri = Uri.fromFile(new File(path));
        InputStream in = null;
        try {
            final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
            in = getContentResolver().openInputStream(uri);

            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(in, null, o);
            in.close();


            int scale = 1;
            while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
                    IMAGE_MAX_SIZE) {
                scale++;
            }
            Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);

            Bitmap b = null;
            in = getContentResolver().openInputStream(uri);
            if (scale > 1) {
                scale--;
                // scale to max possible inSampleSize that still yields an image
                // larger than target
                o = new BitmapFactory.Options();
                o.inSampleSize = scale;
                b = BitmapFactory.decodeStream(in, null, o);

                // resize to desired dimensions
                int height = b.getHeight();
                int width = b.getWidth();
                Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);

                double y = Math.sqrt(IMAGE_MAX_SIZE
                        / (((double) width) / height));
                double x = (y / height) * width;

                Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
                        (int) y, true);
                b.recycle();
                b = scaledBitmap;

                System.gc();
            } else {
                b = BitmapFactory.decodeStream(in);
            }
            in.close();

            Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
                    b.getHeight());
            return b;
        } catch (IOException e) {
            Log.e("", e.getMessage(), e);
            return null;
        }
    }

Hope it helps!

Add these permission in Androidmenifest.xml file

Solution 9

I created a dialog with the option to choose Image from gallery or camera. with a callback as

  • Uri if the image is from the gallery
  • String as a file path if the image is captured from the camera.
  • Image as File the image chosen from camera needs to be uploaded on the internet as Multipart file data

At first we to define permission in AndroidManifest as we need to write external store while creating a file and reading images from gallery

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Create a file_paths xml in app/src/main/res/xml/file_paths.xml

with path

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Then we need to define file provier to generate Content uri to access file stored in external storage

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

                            android:src="@drawable/XXXXXXX"
            android:textAppearance="?android:attr/textAppearanceSmall" />

in manifest.xml:

    <uses-permission android:name="android.permission.CAMERA" />   <uses-feature android:name="android.hardware.camera" />

Solution 11

You can use this code to onClick listener (you can use ImageView or button)

image.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                startActivityForResult(takePictureIntent, 1);
            }
        }
    });

To display in your imageView

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        bitmap = (Bitmap) extras.get("data");
        image.setImageBitmap(bitmap);

    }
}

Note: Insert this to the manifest

<uses-feature android:name="android.hardware.camera" android:required="true" />

Solution 12

As others have discussed, using data.getExtras().get("data") will just get the low-quality thumbnail.

The solution is to pass a location with your ACTION_IMAGE_CAPTURE intent telling the camera where to store the full quality image.

The code is Kotlin and does not need any permissions.


val f = File("${getExternalFilesDir(null)}/imgShot")
val photoURI = FileProvider.getUriForFile(this, "${packageName}.fileprovider", f)
val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
        .apply { putExtra(MediaStore.EXTRA_OUTPUT, photoURI) }
startActivityForResult(intent, 1234)

Then handle the result after the picture was taken:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == 1234 && resultCode == Activity.RESULT_OK) {
        val bitmap = BitmapFactory.decodeFile(
                File("${getExternalFilesDir(null)}/imgShot").toString()
        )
        // use imageView.setImageBitmap(bitmap) or whatever
    }
}

You will also need to add an external FileProvider as described here. AndroidManifest.xml:

<manifest>
    <application>

        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provide_paths" />
        </provider>

    </application>
</manifest>

Add a new file app/src/main/res/xml/provide_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="." />
</paths>

Lastly you should replace 1234 with your own logic for keeping track of request code (usually an enum with a member such as RequestCode.CAPTURE_IMAGE)

Solution 13

You can use custom camera with thumbnail image. You can look my project.

Solution 14

Here is the complete code:

package com.example.cameraa;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class MainActivity extends Activity {




        Button btnTackPic;
        Uri photoPath;
        ImageView ivThumbnailPhoto;

        static int TAKE_PICTURE = 1;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            // Get reference to views

            btnTackPic = (Button) findViewById(R.id.bt1);
            ivThumbnailPhoto = (ImageView) findViewById(R.id.imageView1);




     btnTackPic.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, TAKE_PICTURE); 
            }




    });

        } 

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent intent) {


                if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {  
                    Bitmap photo = (Bitmap)intent.getExtras().get("data"); 
                   ivThumbnailPhoto.setImageBitmap(photo);
                ivThumbnailPhoto.setVisibility(View.VISIBLE);



            }
        }
}

Remember to add permissions for the camera too.

Solution 15

2021 May, JAVA

after handling necessary Permissions described next to this post, in manifest add:

<uses-permission 
    android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission 
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18"  />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
....

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>
....

where ${applicationId} is app's package name , e.g. my.app.com.

In res->xml->provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
 <paths>
  <external-files-path name="my_images" path="Pictures" />
  <external-path name="external_files" path="."/>
    <files-path
    name="files"   path="." />
    <external-cache-path
      name="images" path="." />
 </paths>

in Activity:

private void onClickCaptureButton(View view) {
    Intent takePictureIntent_ = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent_.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile_ = null;
        try {
            photoFile_ = createImageFile();
        } catch (IOException ex) {
        }
        if(photoFile_!=null){
            picturePath=photoFile_.getAbsolutePath();
        }
        // Continue only if the File was successfully created
        if (photoFile_ != null) {
            Uri photoURI_ = FileProvider.getUriForFile(this,
               "my.app.com.fileprovider", photoFile_);
            takePictureIntent_.putExtra(MediaStore.EXTRA_OUTPUT, photoURI_);
            startActivityForResult(takePictureIntent_, REQUEST_IMAGE_CAPTURE);
        }
    }
}

And three more moves:

...
private static String picturePath;
private static final int REQUEST_IMAGE_CAPTURE = 2;
...
private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp_ = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new 
      Date());
    String imageFileName_ = "JPEG_" + timeStamp_ + "_";
    File storageDir_ = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image_ = File.createTempFile(
            imageFileName_,  /* prefix */
            ".jpg",         /* suffix */
            storageDir_      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    picturePath= image_.getAbsolutePath();
    return image_;
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
   if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK 
   ){

        try {
            File file_ = new File(picturePath);
            Uri uri_ = FileProvider.getUriForFile(this,
                    "my.app.com.fileprovider", file_);
            rasm.setImageURI(uri_);
        } catch (/*IO*/Exception e) {
            e.printStackTrace();
        }
    }
}

and

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString("safar", picturePath);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

and:

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
        picturePath = savedInstanceState.getString("safar");
    }
 ....
}

Solution 16

Bitmap photo = (Bitmap) data.getExtras().get("data"); gets a thumbnail from camera. There is an article about how to store a picture in external storage from camera. useful link

Solution 17

Please, follow this example with this implementation by using Kotlin and Andoirdx support:

button1.setOnClickListener{
        file = getPhotoFile()
        val uri: Uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
        captureImage.putExtra(MediaStore.EXTRA_OUTPUT, uri)

        val camaraActivities: List<ResolveInfo> = applicationContext.getPackageManager().queryIntentActivities(captureImage, PackageManager.MATCH_DEFAULT_ONLY)

        for (activity in camaraActivities) {
            applicationContext.grantUriPermission(activity.activityInfo.packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
        }

        startActivityForResult(captureImage, REQUEST_PHOTO)
    }

And the activity result:

if (requestCode == REQUEST_PHOTO) {
        val uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
        applicationContext.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
        imageView1.viewTreeObserver.addOnGlobalLayoutListener {
            width = imageView1.width
            height = imageView1.height
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
        }
        if(width!=0&&height!=0){
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
        }else{
            val size = Point()
            this.windowManager.defaultDisplay.getSize(size)
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , size.x , size.y))
        }

    }

I hope it helps you!

Solution 18

Use the following code to capture picture using your mobile camera. If you are using android having version higher than Lolipop, You should add the permission request also.

private void cameraIntent()
    {
          Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          startActivityForResult(intent, REQUEST_CAMERA);
    }

@override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
     if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
     }  
} 

Solution 19

Bad quality

From my experience if we use

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, RESULT_ADD_PHOTO);

And handle in onActivityResult() with

Bitmap thumbnail= (Bitmap) data.getExtras().get("data");

It will give you thumbnail only and of course have a bad quality.

Nice quality

You can show camera and save your image file in public directory, example in Document directory

Use this in your onClick()

String imagePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS) +
                File.separator + "your_image_name.jpeg";
Intent i =new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageFile = new File(imagePath );
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
startActivityForResult(i, RESULT_ADD_PHOTO);

And in onActivityResult()

Bitmap imageBitmap1 = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap imageBitmap = Bitmap.createBitmap(imageBitmap1, 0, 0, imageBitmap1.getWidth(), imageBitmap1.getHeight(), matrix, true);
binding.imageView.setImageBitmap(imageBitmap);

I use postRotate() because in my code, image result rotate to left so I need to rotate it 90
