Uploading image taken from gallery app (Quality issue)

Using Android's gallery app to select a photo to upload with httppost later. The photo gets uploaded but it's very low quality and size. I have been reading about setting the Bitmap.CompressFormat.PNG will make it lossless but it's taking the photo from 2000x1500 to 250x187.

Is it possible that I'm getting the thumbnail and not the actual image? I'm using Photos from Google.

Code

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

    if ( resultCode == getActivity().RESULT_OK ) {
        selectedImage = Uri.parse( data.getDataString() );

        try {   
            final Bitmap v = DecodeUriImage.Decode( selectedImage, getActivity() );
            ByteArrayOutputStream bao = new ByteArrayOutputStream();
            v.compress( Bitmap.CompressFormat.PNG, 100, bao );
            byte[] byte_arr = bao.toByteArray();

            // Add image to array
            images.set( selectedImageIndex, Base64.encodeToString( byte_arr, Base64.DEFAULT ) );

            } catch ( FileNotFoundException e ) {
                e.printStackTrace();
            } catch ( Exception e ) {
                e.printStackTrace();
            }
        }
    }
}

Result

Image

There is no reason to put the selected image in a Bitmap for later use. Moreover you did not show what all is happening in DecodeUriImage.Decode( selectedImage, getActivity() );. Maybe it's quality is changed there. Instead realise you have a media path in selectedImage which you can convert to a real path to the filesystem. Save that path for later use.

If you use it later than just load the file in a byte array and encode base64. Do not use Bitmapfactory.

The Bitmap.CompressFormat.PNG will compress the image but It depends on what kink of format you have used on the non-compressed image. You should use a vectorial image to get the best results because on the "compressing transfer" the immage loses the quality both in getting the image bigger on not.
