Android notifications not showing up in app

I am writing an app that uses GCM Push Notifications, however when a notification appears, it opens the app but doesn't show the message. When I am in the app though, the messages show up normally. Please help.
This is my Manifest
<?xml version="1.0" encoding="utf-8"?>

Notification Code
public class GCMNotificationIntentService extends IntentService{
//set ID for the notification, so it can be updated
public static final int notifyID = 9001;
NotificationCompat.Builder builder;
public GCMNotificationIntentService() {
super("GcmIntentService");
}
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d("GCMN","GCMNTEST");
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: "
+ extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
sendNotification("Message Received from Google GCM Server:\n\n"
+ extras.get(AppConstants.MSG_KEY));
}
}
GCMBroadcastReceiver.completeWakefulIntent(intent);
}
private void sendNotification(String msg){
Intent resultIntent = new Intent(this, HomeActivity.class);
Log.d("RECEIVEDPT2",msg);
resultIntent.putExtra("msg", msg);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this,0,resultIntent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mNotifyBuilder;
NotificationManager mNotificationManager;
mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
mNotifyBuilder = new NotificationCompat.Builder(this).setContentTitle("Alert")
.setContentTitle("You've received a new message")
.setSmallIcon(R.drawable.ic_cast_dark);
//Set pending intent
mNotifyBuilder.setContentIntent(resultPendingIntent);
//Set vibration
int defaults = 0;
defaults = defaults | Notification.DEFAULT_LIGHTS;
defaults = defaults | Notification.DEFAULT_VIBRATE;
defaults = defaults | Notification.DEFAULT_SOUND;
mNotifyBuilder.setDefaults(defaults);
// Set the content for Notification
mNotifyBuilder.setContentText("You have new notifications");
// Set autocancel
mNotifyBuilder.setAutoCancel(true);
// Post a notification
mNotificationManager.notify(notifyID, mNotifyBuilder.build());
}

As requested in the comments, please include the code for HomeActivity which handles the notification so we can examine the code and suggest solutions. In the meantime, this is how I'd suggest you process the incoming GCM notification in your HomeActivity class (will update the answer once I see you code, if necessary). In my example, I have a helper method processIntent(Intent intent) which handles the Intent and its Extras. I call this method from both onCreate and onNewIntent methods.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.<layout-id>);
//here I call our processing method
processIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
//call our processing method
processIntent(getIntent());
}
/**
* Helper method to process the incoming GCM Notification.
* #param intent
*/
private void processIntent(Intent intent){
if(intent == null) { return; }
Bundle extras = intent.getExtras();
try{
if(extras.containsKey("msg")){
//possibly a message
String message = extras.getString("msg");
Log.i(TAG, "Received Message "+message);
//do whatever with the message, like set as Text of TextView, etc
}
}
catch(Exception e){
Log.e(TAG, "Error Processing GCM Notification Intent", e);
}
}

Android push notification when app is close

I followed the documentation of google to implement push notifications.
When the app is open works fine, but when I close the app does not receive notifications.
Here is the code:

message = notification.getString("body");
}
NotificationUtility.showNotification(title, message);
NotificationUtility.setBadge(1);
}
}
MyInstanceIDListenerService.java
public class MyInstanceIDListenerService extends InstanceIDListenerService {
/**
* Called if InstanceID token is updated. This may occur if the security of

Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}
}
GcmBroadcastReceiver.java
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(), MyGcmListenerService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
When the app is open onMessageReceived of GcmListenerService class is called but when the app is closed is not called.
What did I do wrong?
Thanks

I resolved by updating the play service from com.google.android.gms:play-services:8.3.0 to com.google.android.gms:play-services:8.4.0

How to get push notification message in android?

I am trying to receive the push notification message and send the notification message but i am getting the null value not receive any message.
Below code
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
Log.d("push","msg type: " + messageType);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
} else if (!extras.isEmpty() && GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
Log.d("push notify msg: ", extras.toString());
sendNotification(extras.toString());
}
}
GcmBroadcastReceiver.completeWakefulIntent(intent);
}

Create a receiver and declare it in manifest.
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(),XYZIntentService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
Manifest:
<receiver
android:name="com.companyname.GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="PKG_NAME" />
</intent-filter>
</receiver>
Meta Data Tag:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Permissions:
<permission
android:name="com.vuliv.player.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.vuliv.player.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
Now you can add your code to XYZIntentService to get GCM notification.
For any query feel free to raise.

Follow this link it is a sample project of GCM provided by GOOGLE it will help you

Can't receive messages using Google Cloud Messaging for Android (not the helper library)

Does anybody can help me with a working example for receiving messages from gcm using Google Cloud Messaging for Android. I have tried both ways (helper library and GoogleCloudMessaging class) and nothing seems to work. I'm using a PHP script that shows the following:
Multicast ID: 5.2108110103215E+18
Number of messages processed successfully: 1
Number of messages with processing errors: 0
Canonical IDs: 0
So apparently everithing is OK. I could register the device in both ways, using the helper library (gcm.jar) and using GoogleCloudMessaging class. The problem is that there is no way the message I send via PHP arrives, or at least I don't know how to handle it correctly. Here are the permissions and the receiver from my manifest:
<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<uses-permission android:name="android.permission.READ_OWNER_DATA" />
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<!-- Receives the actual messages. -->
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<!-- Receives the registration id. -->
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.example.gcm" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
Finally here is the service class
public class GCMIntentService extends GCMBaseIntentService {
private static final String PROJECT_ID = "49XXXXXXXX6";
private static final String TAG = "GCM Intent Service";
public GCMIntentService()
{
super(PROJECT_ID);
Log.d(TAG, "GCMIntentService init");
}
#Override
protected void onError(Context ctx, String sError) {
Log.d(TAG, "Error: " + sError);
}
#Override
protected void onMessage(Context ctx, Intent intent) {
Log.d(TAG, "Message Received");
String message = intent.getStringExtra("message");
sendGCMIntent(ctx, message);
}
private void sendGCMIntent(Context ctx, String message) {
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("GCM_RECEIVED_ACTION");
broadcastIntent.putExtra("gcm", message);
ctx.sendBroadcast(broadcastIntent);
}
#Override
protected void onRegistered(Context ctx, String regId) {
Log.d(TAG, regId);
// Notify main UI to update registration status
Intent registrationIntent = new Intent();
registrationIntent.setAction("registered");
registrationIntent.putExtra("regId", regId);
sendBroadcast(registrationIntent);
}
#Override
protected void onUnregistered(Context ctx, String regId) {
//...
}
}
Here is the code when using the GoogleCloudMessaging class (I changed the manifest to use the custom receiver):
public class GCMBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "GCM Receiver";
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
private Context ctx;
#Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, "Message received");
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
ctx = context;
String messageType = gcm.getMessageType(intent);
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("Send error: " + intent.getExtras().toString());
}
else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: "
+ intent.getExtras().toString());
}
else {
sendNotification("Received: " + intent.getExtras().toString());
}
setResultCode(Activity.RESULT_OK);
}
// Put the GCM message into a notification and post it.
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager) ctx
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0,
new Intent(ctx, MainActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
ctx).setSmallIcon(R.drawable.ic_launcher_temp)
.setContentTitle("GCM Notification")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
The thing is that everything seems to be ok, but the message never arrives. Any ideas??
Thanks in advance.

Add the following in your manifeast
<permission
android:name="PACKAGE_NAME.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="PACKAGE_NAME.permission.C2D_MESSAGE" />
<!-- App receives GCM messages. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

Your manifest is missing some permissions :
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
EDIT :
In your manifest you are using com.google.android.gcm.GCMBroadcastReceiver. That's a class from the old helper library (gcm.jar) which starts an intent service. If you want to use the helper library you should define the intent service in your manifest.
If you don't want to use the helper library, you should change the package of GCMBroadcastReceiver in the manifest to be the package of the GCMBroadcastReceiver class that you included in your question. Otherwise, that class won't be used.

After correcting the issues above still no push messages. The problem was the 403 error. Looks like that service is not available in Cuba, so the solution is to use a tool like "your freedom" or "thor", etc.

Don't forget to change 'com.example.gcm' to your package name e.g. 'com.yourdomain.yourapp'

You are using GCMBaseIntentService which has been deprecated by Google. (But it should be still working.) I followed the latest tutorial http://developer.android.com/google/gcm/client.html and did receive messages. You can try it too.
Another possible reason is you may have received a message but it was not shown in a notification successfully. Add this line in the method: sendNotification(String msg)
Log.i(TAG, msg);

GCM: onMessage() from GCMIntentService is called very few times

I am implementing GCM in my application. I have followed all the steps given in GCM tutorial from developer.android.com
My application's build target is pointing to Goolge API 8 (Android 2.2 version).
I am able to get the register ID from GCM successfully, and I am passing this ID to my application server. So the registration step is performed successfully.
Now when my application server sends a PUSH message to my device, the server gets the message as SUCCESS=1 FAILURE=0, etc., i.e. Server is sending message successfully, but my device never receives the message.
After searching alot about this, I came to know that GCM pushes messages on port number 5228, 5229 or 5230.
Initially, my device and laptop was restricted for some websites, but then I was granted all the permissions to access all websites, so I guess these port numbers are open for my device.
So my question is: Very few times, I am receiving PUSH message from GCM. Why Google is so uncertain in delivering messages?
What could be the reason?
Please see my following code and guide me accordingly:
I have declared following in my manifest:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<permission
android:name="package.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<!-- App receives GCM messages. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- GCM connects to Google Services. -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />

Check whether the debug certificate is expired or not, If it is then create new certificate and generate new key.

Try to change your class names as full names with package names. Like:
<service android:name="com.xx.xx.xx" />
And dont forget to put your package name here:
<category android:name="packageName" />

Make sure your app name and the name you registered on the google console for getting api key are same name.Same name in the sense that exactly the same
