apache cordova si blocca dopo aver ricevuto notifica push parse.com

Question

Desidero aggiungere il servizio di notifica push parse.com alla mia app Cordova. Ho letto la guida rapida di parse.com e ho inserito il file SDK nella cartella libs. dopo di che ho aggiunto i codici al file java principale e AndroidManifest.xml. l'app funziona correttamente. parse.com può ricevere il mio token dispositivo e posso inviare notifiche push al dispositivo, ma dopo due o tre notifiche push l'app si blocca.

il messaggio di errore nel CatLog è questo:

05-07 02:08:25.185: E/com.parse.PushService(28735): The Parse push service cannot start because Parse.initialize has not yet been called. If you call Parse.initialize from an Activity's onCreate, that call should instead be in the Application.onCreate. Be sure your Application class is registered in your AndroidManifest.xml with the android:name property of your <application> tag.

I ho cercato e sembra che molti sviluppatori abbiano esattamente lo stesso problema. Ho trovato due argomenti in parse.com forum di assistenza: https://www.parse.com/questions/app-crashes-after-after-screen-unlock https://www.parse.com/questions/cannot-send-push-to-android-after-app-is-closed-until-screen-unlock e questa qui: Android App crashes when push is received and app is closed

ma le soluzioni non è chiaro per qualcuno che non conoscono Java. Come posso modificare il mio AndroidManifest.xml e il file java principale per farlo funzionare.

grazie in anticipo

Answer 1

Il servizio push Parse non possono iniziare perché Parse.initialize non è ancora stato definito. Se chiami Parse.initialize da un onCreate di un'attività, quella chiamata dovrebbe invece essere in Application.onCreate. Assicurati che la tua classe Application sia registrata nel tuo AndroidManifest.xml con la proprietà android: name del tuo tag.

Provare a separare Attività e Applicazione, creare un nuovo file di classe, ad es. Principale dell'applicazione.

PushApp.java:

public class PushApp extends CordovaActivity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     super.init(); 
     // Set by <content src="index.html" /> in config.xml 
     super.loadUrl(Config.getStartUrl()); 
     //super.loadUrl("file:///android_asset/www/index.html"); 
    } 
} 

MainApplication.java:

public class MainApplication extends Application { 
    @Override 
    public void onCreate() { 
     super.onCreate(); 
     Parse.initialize(this, "xJK9ZA0Dtsjd8RwoNUUsIHPXzMRbmcxXGWqiw", "19g9eUKjLjlUdogHEXStUABNcvy2rA6azb5mXy"); 
     PushService.setDefaultPushCallback(this, PushApp.class); 
     ParseInstallation.getCurrentInstallation().saveInBackground(); 
    } 
} 

e il cambiamento:

<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:name="PushApp" android:theme="@android:style/Theme.Black.NoTitleBar"> 

a:

<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:name="MainApplication" android:theme="@android:style/Theme.Black.NoTitleBar"> 

ora si dovrebbe anche ricevere notifiche push quando applicazione è chiusa/schermo è bloccato

Answer 2

controllare il vostro manifest.xml se avete chiamato i <application> come android:name="MainApplication"

ei <activity> come android:name="PushApp"
