我正在测试一个简单的应用程序，它使用 VideoView 从互联网播放 http/rtsp 视频。该应用程序在 3.3 之前的 2.2 版本中运行良好，但是当我在 4.0 及更高版本上对其进行测试时，崩溃！！！（在模拟器和真实手机上都测试过：-/）

谁能给我一个提示为什么？

xml文件：

    <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"

</LinearLayout>

.java文件：

  public class Video extends Activity {
    private static final String TAG = "VideoViewDemo";

    private VideoView mVideoView;
    private EditText mPath;
    private ImageButton mPlay;

    private Uri current;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.video);
        mVideoView = (VideoView) findViewById(R.id.surface_view);

        mPath = (EditText) findViewById(R.id.path);
        mPath.setText("http://daily3gp.com/vids/747.3gp");

        playVideo();

        mPlay = (ImageButton) findViewById(R.id.play);

        mPlay.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                playVideo();
            }
        });

        runOnUiThread(new Runnable(){
            public void run() {
                playVideo();

            }

        });
    }

    private void playVideo() {
        try {
            //final String path = mPath.getText().toString();
            Uri path = Uri.parse(mPath.getText().toString());
            Log.v(TAG, "path: " + path);
            if (path == null) {
                Toast.makeText(Video.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.start();
                    mVideoView.requestFocus();
                    return;
                }
                current = path;
                mVideoView.setVideoURI(path);
                mVideoView.start();
                mVideoView.requestFocus();

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


}

这里是带有错误的 Logcat 文件：

手机上的崩溃错误只是说“不幸的是，Test VideoView 已停止”

提前谢谢！
