getBitmap deprecated in API 29 java android

Question

I am developing an android application I want user to select an image from gallery. But I have seen that getBitmap is deprecated on API 29

I have tried ImageDecoder.decodeBitmap(Imagedecoder.createSource()) but it crashes the application

if (requestCode == GALLERY){
            if (data != null) {
                Uri contentURI = data.getData();
                try {
                    if (contentURI!=null){
                        bitmap = ImageDecoder.decodeBitmap(ImageDecoder.createSource(getContentResolver(), contentURI));
                        Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
                        pic.setImageBitmap(bitmap);
                    }
                    dialog.show();
                } catch (Exception e){
                    e.printStackTrace();
                    Toast.makeText(getApplicationContext(), "Failed!", Toast.LENGTH_SHORT).show();
                }
            }
        }

I am not getting that why app is crashing.

here is crash log

Answer 1

From Documentation of public static Bitmap getBitmap (ContentResolver cr, Uri url)

This method was deprecated in API level 29. loading of images should be performed through ImageDecoder#createSource(ContentResolver, Uri), which offers modern features like PostProcessor.

Example algorithm can be

if (android.os.Build.VERSION.SDK_INT >= 29){
    // To handle deprication use   
    ImageDecoder.decodeBitmap(Imagedecoder.createSource())
} else{
    // Use older version
    MediaStore.Images.Media.getBitmap(contentResolver, imageUri)
}
