POpush notification doesn't show number of messages

copied!<p>I'm following this <a href="http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/" rel="nofollow">tutorial</a> and its working fine, but problem is: it shows only the last message and all previous are removed. If I sent 3 messages from the server, it does not show number count as (3) in notification bar. It only displays the last message (all previous are deleted) as well.</p> <pre><code>public class MainActivity extends Activity { // label to display gcm messages TextView lblMessage; // Asyntask AsyncTask<Void, Void, Void> mRegisterTask; // Alert dialog manager AlertDialogManager alert = new AlertDialogManager(); // Connection detector ConnectionDetector cd; public static String name; public static String email; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); cd = new ConnectionDetector(getApplicationContext()); // Check if Internet present if (!cd.isConnectingToInternet()) { // Internet Connection is not present alert.showAlertDialog(MainActivity.this, "Internet Connection Error", "Please connect to working Internet connection", false); // stop executing code by return return; } // Getting name, email from intent Intent i = getIntent(); name = i.getStringExtra("name"); email = i.getStringExtra("email"); // Make sure the device has the proper dependencies. GCMRegistrar.checkDevice(this); // Make sure the manifest was properly set - comment out this line // while developing the app, then uncomment it when it's ready. GCMRegistrar.checkManifest(this); lblMessage = (TextView) findViewById(R.id.lblMessage); registerReceiver(mHandleMessageReceiver, new IntentFilter( DISPLAY_MESSAGE_ACTION)); // Get GCM registration id final String regId = GCMRegistrar.getRegistrationId(this); // Check if regid already presents if (regId.equals("")) { // Registration is not present, register now with GCM GCMRegistrar.register(this, SENDER_ID); } else { // Device is already registered on GCM if (GCMRegistrar.isRegisteredOnServer(this)) { // Skips registration. Toast.makeText(getApplicationContext(), "Already registered with GCM",Toast.LENGTH_LONG).show(); } else { // Try to register again, but not in the UI thread. // It's also necessary to cancel the thread onDestroy(), // hence the use of AsyncTask instead of a raw thread. final Context context = this; mRegisterTask = new AsyncTask<Void, Void, Void>() { @Override protected Void doInBackground(Void... params) { // Register on our server // On server creates a new user ServerUtilities.register(context, name, email, regId); return null; } @Override protected void onPostExecute(Void result) { mRegisterTask = null; } }; mRegisterTask.execute(null, null, null); } } } /** * Receiving push messages * */ private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String newMessage = intent.getExtras().getString(EXTRA_MESSAGE); // Waking up mobile if it is sleeping WakeLocker.acquire(getApplicationContext()); /** * Take appropriate action on this message * depending upon your app requirement * For now i am just displaying it on the screen * */ // Showing received message lblMessage.append(newMessage + "\n"); Toast.makeText(getApplicationContext(), "New Message: " + newMessage, Toast.LENGTH_LONG).show(); // Releasing wake lock WakeLocker.release(); } }; @Override protected void onDestroy() { if (mRegisterTask != null) { mRegisterTask.cancel(true); } try { unregisterReceiver(mHandleMessageReceiver); GCMRegistrar.onDestroy(this); } catch (Exception e) { Log.e("UnRegister Receiver Error", "> " + e.getMessage()); } super.onDestroy(); } } </code></pre>
