Sto implementando GCM nella mia applicazione. Ho seguito tutti i passaggi indicati nel tutorial GCM da developer.android.comGCM: onMessage() di GCMIntentService viene chiamato Molte volte?
Sono in grado di ottenere l'ID registro da GCM con successo e sto passando questo ID al mio server applicazioni. Quindi la fase di registrazione viene eseguita con successo.
Ora, quando il mio server applicazione invia un messaggio push al dispositivo, il server ottiene il messaggio come SUCCESS = 8 GUASTO = 0, ecc, cioè Server sta inviando un messaggio con successo, ma OnMessage sempre chiamato 8 volte dipende il valore del successo.
Il mio dispositivo collegato gira il wifi della mia organizzazione senza impostazioni proxy.
Quindi la mia domanda è: perché sto ricevendo il messaggio PUSH da GCM come valore di tempo del successo. Perché Google sta offrendo così tanto tempo? Quale potrebbe essere la ragione?
mio GCMBaseIntentService sembra
public class GCMIntentService extends GCMBaseIntentService {
public GCMIntentService() {
super(GCMActivity.SENDER_ID);
}
@Override
protected void onError(Context arg0, String arg1) {
Log.d("GCM", "RECIEVED A ERROR MESSAGE");
// TODO Auto-generated method stub
}
@Override
protected void onRegistered(Context arg0, String registrationId) {
//Send the registration id to my app server to store the reg id list
GCMActivity.sendRegIdtoApplicationServer(registrationId);
}
@Override
protected void onUnregistered(Context arg0, String registrationId) {
// TODO Auto-generated method stub
}
@Override
protected void onMessage(Context context, Intent intent) {
Log.d("GCM", "RECIEVED A MESSAGE");
// Get the data from intent and send to notificaion bar
String data = intent.getStringExtra("data");
String action = intent.getAction();
if((action.equals("com.google.android.c2dm.intent.RECEIVE"))) {
try {
JSONObject jsonObject = new JSONObject(data);
boolean updateStatus = jsonObject.getBoolean("update");
if (updateStatus) {
//Showing Notification to user
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
La mia attività si presenta come
public class GCMActivity extends Activity {
public final static String SENDER_ID = "872355133485";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gcm);
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
GCMRegistrar.register(this, SENDER_ID);
} else {
// sendRegIdtoApplicationServer(regId);
Log.v("gh", "Already registered");
System.out.println("RegisterID:"+ regId);
}
}
And Manifest file will be

Nelle mie app GCM non lo fa - sembra più un bug nel tuo codice se me lo chiedi - puoi mostrare il codice? – ligi
@ ligi ho aggiunto il mio codice. – Lakshmanan
dov'è il codice lato server in cui si invia il messaggio con un particolare ID di registrazione? – appukrb
