Question

我尝试通过意图播放视频。我用这个方法：

   private void play_video() {
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/nabege" + File.separator + "video"
        + File.separator + videoFileName);
intent.setDataAndType(Uri.fromFile(file), "video/*");
startActivity(intent);}

结束时播放视频停止应用。

我在Internet上搜索，我知道我最常使用registerReceiver（）和unregisterreceiver（）方法。现在我不明白如何使用这两种方法。请指导我

您的堆栈跟踪来自另一个应用，而非您的应用：

Activity com.android.gallery3d.app.MovieActivity has leaked IntentReceiver com.android.gallery3d.app.MovieActivity$6@41b61bf8 that was originally registered here. Are you missing a call to unregisterReceiver()?

您没有编写名为com.android.gallery3d.app.MovieActivity的活动。这是播放视频的第三方应用。显然，你在该应用程序中看到了一个错误。你无能为力。

为什么在意图播放视频后停止app？
