Camera intent gives null at onActivityResult

Question

I am working on Android application in which I am getting image from gallery and camera. For gallery image I am getting perfectly intent values at onActivityresult but on camera when I want to get intent.getData() for Uri it gives Null value.

My code is given below:

public void onClick(DialogInterface dialog, int item) {

                         if(item==1){
                         Intent intent = new Intent();
                            intent.setType("image/*");
                            intent.setAction(Intent.ACTION_GET_CONTENT);
                            startActivityForResult(Intent.createChooser(intent,
                                    "Select Picture"), SELECT_PICTURE);
                     }if(item==0){

                            dispatchTakePictureIntent();
                        // open();
                     }else{
                         alert.cancel();
                     }
                     alert.cancel();
                     }
                   });


private void dispatchTakePictureIntent() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            // Uri selectedImageUri1 = data.getData();
            if (requestCode == SELECT_PICTURE) {
                Uri selectedImageUri = data.getData();
                if (Build.VERSION.SDK_INT < 19) {
                    selectedImagePath = getPath(selectedImageUri);

                    Picasso.with(this).load(selectedImageUri).resize(100, 100).transform(new CircleTransform() {
                        @Override
                        public Bitmap transform(Bitmap source) {
                            int size = Math.min(source.getWidth(), source.getHeight());

                            int x = (source.getWidth() - size) / 2;
                            int y = (source.getHeight() - size) / 2;

                            Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
                            if (squaredBitmap != source) {
                                source.recycle();
                            }

                            Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

                            Canvas canvas = new Canvas(bitmap);
                            Paint paint = new Paint();
                            BitmapShader shader = new BitmapShader(squaredBitmap,
                                    BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
                            paint.setShader(shader);
                            paint.setAntiAlias(true);

                            float r = size / 2f;
                            canvas.drawCircle(r, r, r, paint);

                            squaredBitmap.recycle();

                            return bitmap;
                        }
                    }).into(image);

                }
            }
            if (requestCode == REQUEST_IMAGE_CAPTURE) {
                Bundle extras = data.getExtras();
                Uri selectedImageUri = data.getData();
                // data.getData() gives null value
                Bitmap imageBitmap = (Bitmap) extras.get("data");
                image.setImageBitmap(imageBitmap);

            }
}

AFAIK, you can get with Intent data only thumbnail or something like this, moreover some devices don't return thumbnail at all. To capture and get photo you can refer to this.

You need Providers while using camera intent.

file_paths.xml:

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

Camera permission:

 private void askCameraPermissions() {
        if(ContextCompat.checkSelfPermission(this,Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(this,new String[] {Manifest.permission.CAMERA}, CAMERA_PERM_CODE);
        } 
    }

Camera intent:

 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) {

            }
            // Continue only if the File was successfully created
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this,
                        "com.example.android.fileprovider",
                        photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, SELECT_PICTURE);
            }
        }

Manifest:

<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>
