Android App Absturz auf Google Maps Aktivität

Question

Es wird die Fehlermeldung angezeigt, dass die App leider geschlossen ist, wenn ich von der AddReminder Aktivität zu der AddEventPlace Aktivität gehe.

Answer 1

Der Fehler ist klar:

Fehlende erwartete Ressource: "R.string.google_app_id" für Initialisierung der Google-Dienste.

Sie müssen google_app_id auf Ihre Ressourcen wie folgt hinzuzufügen:

<string name="google_app_id">PROJECT_NUMBER</string> 

Sie können Ihre Projektnummer aus dem Google Developer Console

Answer 2

Wie logcat erzeugen vorschlagen, dass Sie nicht richtig Setup Google-Service.

Eine erwartete Ressource fehlt: 'R.string.google_app_id' für Initialisierung der Google-Dienste. Mögliche Ursachen sind fehlende google-services.json oder com.google.gms.google-Dienste

    android:name="com.google.android.geo.API_KEY" 
    android:value="@string/google_api_key" />
