Android ActivityRecognition java.lang.NullPointerException: Nie zażądano odpowiedniego Api

Question

Próbuję podążać za przykładem Google'a Activity Recognition.

W przykładzie rozpoczynają rozpoznawanie aktywności po kliknięciu przycisku, jednak chciałbym go uruchomić po uruchomieniu aplikacji - dlatego próbowałem go umieścić w metodzie onConnected. Jednak kończy się wyrzucanie wyjątku wskaźnika pustego.

Oto jak dzwonię go:

@Override 
public void onConnected(Bundle connectionHint) { 
    Log.d(TAG, "onConnected"); 
    try { 
     ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(
       mGoogleApiClient, 
       UPDATE_INTERVAL_IN_MILLISECONDS, 
       getActivityDetectionPendingIntent() 
     ).setResultCallback(this); 

    } catch (SecurityException securityException) { 
     logSecurityException(securityException); 
    } 
} 

i błąd:

pomysłów, co muszę zrobić inaczej, aby uniknąć tego błędu? Inne usługi lokalizacyjne działają dobrze - jak geofencing lub żądanie aktualizacji aktywności.

Answer 1

Problem polegał na tym, że dodawałem LocationServices.API do klienta Google API, ale nie dodawałem ActivityRecognition.API. Po tym, jak zaktualizowałem swoje połączenie, zadziałało:

protected synchronized void buildGoogleApiClient() { 
     mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) 
       .addConnectionCallbacks(this) 
       .addOnConnectionFailedListener(this) 
       .addApi(LocationServices.API) 
       .addApi(ActivityRecognition.API) 
       .build(); 
    }
