推荐答案

试试这个，可能是你的媒体文件的路径是错误的。使用下面的方法，你会得到确切路径。它为我工作

Try this, May be you media file path was wrong. Use below method you will get exact path. Its working for me

 Bitmap thumb = ThumbnailUtils.createVideoThumbnail(getPath(outputFileUri),
                        MediaStore.Images.Thumbnails.MINI_KIND);

photo_Img.setImageBitmap(thumb);

/**
 * Get file path
 */
public static String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = context.managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
