Image orientation get changed after selecting

Question

I want to set background image for a view using Intent.ACTION_GET_CONTENT and handled onActivityResult method as...

public void onActivityResult(int requestCode, int resultCode, Intent data) {    
    if (resultCode == RESULT_OK && requestCode == SELECT_PICTURE) {
        Uri selectedImageUri = data.getData();        
        try {
            InputStream inputStream = 
               getContentResolver().openInputStream(selectedImageUri);
            Drawable drawable = Drawable.createFromStream(inputStream,     
               selectedImageUri.toString());
            mView.setBackground(drawable);
        } catch(FileNotFoundException e) {}
    }
}

It works fine for some images from gallary but not for all images. Image orientation get changed after selecting some image.

the image orientation by default is landscape in many phones especially samsung. You need to check for exif rotation tag in your image before displaying it — Illegal Argument, Jun 16 '14 at 11:27

Try below code:-

try {
        File f = new File(imagePath);
        ExifInterface exif = new ExifInterface(f.getPath());
        int orientation = exif.getAttributeInt(
                ExifInterface.TAG_ORIENTATION,
                ExifInterface.ORIENTATION_NORMAL);

        int angle = 0;

        if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {
            angle = 90;
        } else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) {
            angle = 180;
        } else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {
            angle = 270;
        }

        Matrix mat = new Matrix();
        mat.postRotate(angle);
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 2;

        Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f),
                null, options);
        bitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
                bmp.getHeight(), mat, true);
        ByteArrayOutputStream outstudentstreamOutputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100,
                outstudentstreamOutputStream);
        imageView.setImageBitmap(bitmap);

    } catch (IOException e) {
        Log.w("TAG", "-- Error in setting image");
    } catch (OutOfMemoryError oom) {
        Log.w("TAG", "-- OOM Error in setting image");
    }
