In the latest API 24, you may face some issues if you stick with an approach in the accepted answer.

for example in this line int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); sometimes I got W/System.err: java.lang.IllegalArgumentException: column '_data' does not exist error message.

also in the latest API, you may get SecurityException if you deal with widgets or shared content. Keep that in mind.

As for the video thumbnail from Uri - I use an approach which utilizes MediaMetadataRetriever, thus you don't need to get String filePath:

            MediaMetadataRetriever mMMR = new MediaMetadataRetriever();
            mMMR.setDataSource(context, videoUri);
            bmp = mMMR.getFrameAtTime();

Hope this helps
