使用 VideoView 播放视频会导致 MediaPlayer(1873): 错误 (1, -2147483648)

Question

当我尝试使用 VideoView 播放 3GP 视频时，出现以下错误：

MediaPlayer（1873）：错误（1，-2147483648）

我的源代码是：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.videoplayer);
        mVideoView = (VideoView) findViewById(R.id.surface_view);
        mVideoView.setOnErrorListener(this);
        mVideoView.setOnCompletionListener(this);
        mVideoView.setOnPreparedListener(this);
        mVideoView.requestFocus();

        /*
         * MediaController mc=new MediaController(VideoPlayer.this); mc.show(0);
         * mc.setEnabled(true); mVideoView.setMediaController(mc);
         */

        Intent intent = getIntent();
        if (intent == null) {
            System.out.println("intent is null");
            return;
        }
        Util.showToast(R.string.play_video, VideoPlayer.this);
        String mUri = intent.getStringExtra("path");
        mVideoView.setVideoPath(mUri);
        mVideoView.start();
        System.out.println("path: " + mUri);

    }

错误信息是：

如何解决这个问题？

Answer 1

我找到根本原因：我的应用程序没有访问/mnt/media/Video/VID_20000101_001843.3gp的权限。
