在 android 2.2 和 2.3 上播放视频，但在 Android 4.0.4 上不播放

Question

我正在开发 android 应用程序来播放实时流。他们在 OS 2.2 和 2.3 上运行良好。给我们的新设备是 OS 4.0.4，每次我都会出错； onErrorListener() 方法中的媒体错误未知。这是我的代码

    mVideoView = new VideoView(this);// (VideoView)
    mVideoView.setId(id_mVideoview);

    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

    mVideoView.setLayoutParams(lp);

    mVideoView.setOnKeyListener(this);
    mVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {

        public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
            // TODO Auto-generated method stub
            mHandler.removeCallbacksAndMessages(null);
            Toast.makeText(
                    streamplayer_filmstrip.this," Video cannot be        played", Toast.LENGTH_LONG)
                    .show();
            try {
                Thread.sleep(3000);
                Go_Back();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                Log.d("VidError",
                        "Exception :: " + e.toString() + e.getMessage());
                Toast.makeText(streamplayer_filmstrip.this,
                        "On Error Ex ::" + e.toString(), Toast.LENGTH_LONG)
                        .show();
                e.printStackTrace();
            }
            return true;
        }
    });

    mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

        public void onPrepared(MediaPlayer arg0) {
                    // doneSomething        
                    });


       mVideoView.setVideoURI(Uri.parse(getStreamURL("some_url_for_live_stream")));

        mVideoView.postInvalidateDelayed(100);
        mVideoView.setMediaController(null);
        if (mView1.getVisibility() == View.GONE)
            mVideoView.requestFocus();
        else {
            ll_PopUp.bringToFront();
            mView1.requestFocus();
        }
        mVideoView.start();

非常感谢任何帮助

根据设备类型，Android 中的视频处理方式不同，您应该提及您的设备以及您使用的流媒体类型，android 支持 rtsp 流媒体，对于其他版本，您的设备可能支持流媒体，也可能不支持流媒体输入。
