Images don't show gallery effects

Question

I'm getting images from uris, but they aren't showing any of the gallery effects that have been made (ie. grayscale, sepia). I'm hoping to get the edited images. For example:

ContentResolver cr = activity.getContentResolver();
Cursor cur = cr.query(
       MediaStore.Images.Media.EXTERNAL_CONTENT_URI, // data
       new String[] { MediaStore.Images.Media._ID, 
       MediaStore.Images.Media.BUCKET_DISPLAY_NAME }, // Which columns to return
       "", // Which rows to return (all rows)
       null, // Selection arguments (none)
       MediaStore.Images.Media.DATE_ADDED+" DESC" // Ordering
);

ArrayList<String> bucketImageList = new ArrayList<String>();

//get bitmap thumbnails for all albums
if (cur.moveToFirst()) {
       String bucketName;
       String imageID;
       do {
               imageID = cur.getString(cur.getColumnIndex(MediaStore.Images.Media._ID));
               Uri uri = Uri.parse("content://media/external/images/media");
               uri = Uri.withAppendedPath(uri, "" + imageID);
               bucketImageList.add(uri.toString());
       } while (cur.moveToNext());
       cur.close();
       bucketImages = bucketImageList.toArray(new String[bucketImageList.size()]);
} 
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(bucketImages[2]));

This bitmap will not show any effects made in the Gallery app (Except the Motorola Gallery app).

Your example is too small, Dave! I appreciate synthesis, but this is too much! — Phantômaxx, Jun 03 '14 at 18:45
`they aren't showing any of the gallery edits that have been made (ie. grayscale, sepia)` - Do you **save** your altered images? — Phantômaxx, Jun 03 '14 at 18:47
Yes. In Motorola's Gallery app, it creates a new image. In Android's default app it simply saves what edits have been made to the image. It doesn't actually edit the image, but just displays the edits. This way you can always undo the saved changes. — Randall Stephens, Jun 03 '14 at 18:54

Your code should look similar to this:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK)
    {
        Uri imageUri = data.getData();
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
    }
}

If you need to load very large images, the following code will load it in in tiles (avoiding large memory allocations):

BitmapRegionDecoder decoder = BitmapRegionDecoder.newInstance(myStream, false);  
Bitmap region = decoder.decodeRegion(new Rect(10, 10, 50, 50), null);

Thanks for your help, but I've managed to load bitmaps from uris. It's just not loading the edits that were made using the Gallery app. It's simply loading the original image. — Randall Stephens, Jun 03 '14 at 18:56
