我正在尝试在Android应用程序中设置firebase消息,据我所知,我需要运行 FirebaseApp.initializeApp(context) 在我处理firebase类之前。我的问题是我在跑步 initializeApp FirebaseInstanceId.getInstance().getInstanceId() ,但firebase仍引发此错误:

09-05 11:16:20.314 24640-24640/com.company.AppName E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.company.AppName, PID: 24640

下面是初始化firebase并抛出错误的代码(在 MainActivity.java onCreate

FirebaseApp.initializeApp(this);
NativeApp
    .shared()
    .setContext(this)
    .setDeviceToken(FirebaseInstanceId.getInstance().getInstanceId().toString());
