Firebase throwing uninitialized error despite being initialized

I'm trying to setup firebase messaging in an Android app, and from what I understand I need to run FirebaseApp.initializeApp(context) before I do anything else with the firebase classes. The problem I'm having is I'm running initializeApp before trying to get the device token with FirebaseInstanceId.getInstance().getInstanceId(), but firebase is still throwing this error:

09-05 11:16:20.314 24640-24640/com.company.AppName E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.company.AppName, PID: 24640
    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.company.AppName/com.company.AppName.MainActivity}: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.company.AppName. Make sure to call FirebaseApp.initializeApp(Context) first.

Here is the code that initializes firebase and throws the error (in MainActivity.java onCreate):

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

If I comment out the setDeviceToken line, no error is thrown. Is initializeApp asynchronous? The Firebase Android setup guide manages to not even mention initializeApp.

You do not need to call initializeApp if you performed an integration with Firebase using the documented procedure. If you do a standard integration, Firebase will be initialized automatically at app launch. Please read more about this in the API docs for FirebaseApp.

If you didn't perform a standard integration, then it's up to you to call initializeApp at the right time for your use case.
