Get Video Thumbnail from Uri

Question

I want to select a video from my Gallery. It\'s working fine. But now I want to display a Bitmap, as a thumbnail.I tired this code it\'s not working, it always says: NullPoi

Answer 1

1. createVideoThumbnail() needs the file path, not the content uri.
2. The file path requires external read permissions.

If you're getting null responses, it may be from using the content uri (though the assumption in ThumbnailsUtils.java is of a corrupt video file). When I fixed that, then I was getting permissions errors.

I was able to get the file path from the content uri using the video's ID like this:

val selection = MediaStore.Video.Media._ID + " = $id"
val cursor = 
this.contentResolver.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, null, 
selection, null, null)      

And then continue on with the cursor as in the other answers in SO.
