我正在制作一个应用程序，其中的一项功能是每 10 秒更新一次用户位置。到目前为止，应用程序没有更新它的位置，因为在检索位置之前，活动已暂停并重新启动。我不明白为什么要重新启动活动。我最好的猜测是，由于没有很多事情发生，操作系统正在暂停活动，但是什么会触发活动重新启动？我之前尝试过构建应用程序，然后我从头开始，因为我犯了太多错误，但即使如此，我以前也没有遇到过这个问题。

正如标题所示,我试图覆盖onRequestPermissionsResult抽象方法,但Gradle说该方法没有超类.

根据文档,超级类是ActivityCompat我导入的.

我正在为基于位置的应用创建位置对象.

我该如何解决这个问题？
