Question

目前正在尝试从返回的视频中获取缩略图（来自图库或来自设备上的视频目标）以在ImageView中显示，但是我收到FileNotFound异常并返回空位图。不完全确定我哪里出错了，虽然从错误判断它必定是不正确的路径。有什么想法吗？

if (requestCode == GALLERY_VIDEO_CODE  || requestCode == VIDEO_CODE) {
            videoURI = data.getData();
            if(videoURI != null) {
                MediaPlayer mp = MediaPlayer.create(this, videoURI);
                int duration = mp.getDuration();
                mp.release();
                if (duration <= 11000) {
                    addBtn.setVisibility(View.INVISIBLE);
                    clearBtn.setVisibility(View.VISIBLE);
                    Toast.makeText(this, "Video added!", Toast.LENGTH_LONG).show();
                    File file = new File(videoURI.getPath());
                    Bitmap bm = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MINI_KIND);
                    userPhoto.setImageBitmap(bm);
                } else {
                    videoURI = null;
                    Toast.makeText(this, "Video too long - maximum duration is 10 seconds", Toast.LENGTH_LONG).show();
                    addBtn.setVisibility(View.VISIBLE);
                    clearBtn.setVisibility(View.INVISIBLE);
                }

通过使用以下方法将文件路径放入createVideoThumbnail（）方法，解决了这个问题：https://stackoverflow.com/a/20470572/5325511

Android ThumbnailUtils返回null，filenotfoundexception？
