单击我的应用程序的按钮时，我正在尝试使用手机上的默认应用程序打开一个 xml 文件。在谷歌之后我发现并遵循了这个：http ://www.androidsnippets.com/open-file-with-default-application-using-intents ，我的代码就像：

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(_file), "application/*"); 
startActivity(intent);

它可以在我的手机上运行，​​但是 logcat 出现了一些错误：

我没有注册任何东西，也不知道如何解决“您是否错过了对 unregisterReceiver() 的调用”，我该如何更改我的代码？

我不是 100% 确定，但如果它工作正常并且抛出异常，你可能不需要对此做任何事情。这可能是您设备的问题，例如，供应商 Android 操作系统自定义错误。尝试在模拟器上测试它，如果它不会抛出异常，就让它保持原样。我认为你的代码很好。
