Question

我有一个videoView，我想在其中显示来自URL的MP4视频。我在Andoird 4.0.2模拟器上尝试过，它工作正常。但是，在使用GingerBread硬件时尝试它，它崩溃了。我也尝试过姜饼模拟器，认为我的设备可能有问题，但仍然没有进展。当我点击“播放”按钮时，logcat会一次又一次地重复这些。

它没有显示任何错误，因此我可以知道哪条线正是导致问题的原因。这是Play按钮的代码：

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();
        }
    }
}

任何帮助都将受到高度赞赏。感谢。

您可能想尝试此代码，

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();
  }
});

MP4视频无法在Android 2.3上播放
