MP4視頻不能在Android 2.3上播放

Question

我有一個videoView，我想在其中顯示來自URL的MP4視頻。我在Andoird 4.0.2模擬器上試了一下，效果很好。但是，在GingerBread硬件上嘗試時，它崩潰了。我也嘗試過薑餅模擬器，認爲我的設備可能有問題，但仍然沒有進展。當我點擊播放按鈕時，logcat會重複這些操作。

它沒有顯示任何錯誤，這樣我就可以知道哪個線恰好導致了問題。這裏的播放按鈕的代碼：

try { 
     final String path = mPath.getText().toString(); 
     Log.v(TAG, "path: " + path); 
     if (path == null || path.length() == 0) { 
      Toast.makeText(MainActivity.this, "File URL/path is empty", 
        Toast.LENGTH_LONG).show(); 

     } else { 
      // If the path has not changed, just start the media player 
      if (path.equals(current) && mVideoView != null) { 


       mVideoView.setVideoURI(Uri.parse("http://173.193.24.66/~kanz/video/mp4/9.mp4")); 

       mVideoView.requestFocus(); 

       mVideoView.start(); 
       return; 
      } 
      current = path; 

      mVideoView.setVideoURI(Uri.parse(getDataSource(path))); 


      mVideoView.requestFocus(); 
      mVideoView.start(); 


     } 
    } catch (Exception e) { 
     Log.e(TAG, "error: " + e.getMessage(), e); 
     if (mVideoView != null) { 
      mVideoView.stopPlayback(); 
     } 
    } 
} 

任何幫助將高度讚賞。謝謝。

你可能想試試這個代碼，

String videoSource = "http://173.193.24.66/~kanz/video/mp4/9.mp4"; 

myVideoView.setMediaController(new MediaController(this)); 
myVideoView.setVideoPath(videoSource); 
myVideoView.requestFocus(); 
myVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
    public void onPrepared(MediaPlayer mp) { 
    myVideoView.start(); 
    } 
});
