Android: ThumbnailUtils.createVideoThumbnail return black bitmap



I am dealing with the thumbnail in Android. Even though I use the function ThumbnailUtils.createVideoThumbnail provided by Android, it gets black bitmap.

I start my research and find out some links:
1/ Thumbnail null
2/ Video Thumbnail return null

However, I checked my returned bitmap and figure out that it is not null.

Please let me know if you have any ideas.

Any suggestion would be appreciated. Thank you in advance!
