Answer 1

You can try to get some frame out of your video just like this:

Uri  videoURI = Uri.parse("android.resource://" + getPackageName() +"/"
        +R.raw.cashword_video);
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(this, videoURI);
Bitmap bitmap = retriever
        .getFrameAtTime(100000,MediaMetadataRetriever.OPTION_PREVIOUS_SYNC);
Drawable drawable = new BitmapDrawable(getResources(), bitmap);

Video on res/raw folder of your application aren't managed by Android Media Content Provider, so you cannot obtain their thumbnail from it.

Alternatively, you can try to save them as normal file in your SD and, then, ask to media provider for thumbnail or create it directly via ThumbnailUtils.createVideoThumbnail class (only Android 2.2 or above)
