Question

当我使用VideoView时，它会引发异常。这是我的代码：

mMediaController = new MediaController(this);
mVideoView.setVideoURI(Uri.parse("http://www.somesite.com/household/uploads/jobs.mp4"));
mVideoView.setMediaController(mMediaController);
mVideoView.requestFocus();

这是一个例外：

E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.spark.peak, PID: 12065
android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

你能帮助我吗？
