Errore Parse: Parse # enableLocalDatastore (Context) `deve essere richiamato prima di` Parse # initialize (Context) `

Question

Quindi ho seguito le istruzioni dalla Guida Rapida dal sito Web Parse SDK. L'app funziona bene la prima volta. Ma quando minimizzo l'app ed eseguo di nuovo dal commutatore di attività, la forzatura si chiude.

L'errore non ha alcun senso per me. Logcat -

Mainactivity.java

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     if(!ParseCrashReporting.isCrashReportingEnabled()) 
      ParseCrashReporting.enable(this); 

     Parse.enableLocalDatastore(this); //Its already before initialize 
     Parse.initialize(this, "XXX", "XXX"); 
     ParseInstallation.getCurrentInstallation().saveInBackground(); 
     ParseAnalytics.trackAppOpenedInBackground(getIntent()); 
    } 

Answer 1

Si può avere una classe separata che fanno questa roba inizializzazione. Quindi creare una classe ParseApplication che si estende Application.

public class ParseApplication extends Application { 

    @Override 
    public void onCreate() { 
     super.onCreate(); 

     ParseCrashReporting.enable(this); 
     Parse.enableLocalDatastore(this); 
     Parse.initialize(this, "xxx", "xxx"); 
    } 
    } 

E in AndroidManifest.xml, aggiungere ParseApplication classe Application

<application 
     android:name="com.example.parsetry.ParseApplication" // you should replace this based on your package 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name=".MainActivity" 
      android:label="@string/app_name" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application>
