I've been working on an Android app that uses QuickBlox for chatting. The chat is working fine, but I am encountering difficulties with the push notifications for logged out users.
The problem is that some devices sometimes stop receiving notifications. It often works fine for a couple of hours, but then suddenly completely stops working for that device. A full manual uninstall + reinstall (which then logs the user in again to QuickBlox + GCM) usually solves the problem.
Looking at the QuickBlox admin panel, I can see that some subscriptions lose their push token.
User 1 registered on device A. Push token has disappeared.

User 1 registered on device B. Push token still present.
http://i.stack.imgur.com/Yu5IQ.png
I register with GCM + QuickBlox push messages once the user is logged in to QuickBlox. This code was largely taken from the QuickBlox chat sample.

To allow a user to receive notifications, I log him out every time the app goes to the background (using onStop in a BaseActivity) and then log back in when the app resumes (which then again starts the PlayServicesHelper).
ChatService.getInstance().logout(null);
The app also uses Parse (with GCM) for push notifications, but the problem still seemed to occur when I disabled Parse.
Could the problem be caused by having one user registered on multiple devices at the same time? Could the frequent app installs (without manually removing the previous installation) result in this behavior?
Push token can disappear if 2 users use the same device
for example, User 1 subscribed for pushes on deviceA
Then User 2 subscribed for pushes on deviceA (the same device)
After this only User 2 will be receiving pushes, not User 1
Is there a chance to have such logic in your case?

After a lot of searching and following this guide https://github.com/codepath/android_guides/wiki/Google-Cloud-Messaging

And this is my script in which i am making the post requests
REGISTRATION_ID=xxxxxx

curl --header "Authorization: key=$SERVER_KEY" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{ \"data\" : {\"foo\": \"bar\"}, \"registration_ids\":[\"$REGISTRATION_ID\"] }"
GCM response 'Not Registered' means following "If it is NotRegistered, you should remove the registration ID from your server database because the application was uninstalled from the device or it does not have a broadcast receiver configured to receive com.google.android.c2dm.intent.RECEIVE intents." from documentation. Check in what case you get this error, when app is uninstalled from device or your describe incorrect broadcastreceiver in AndroidManifest. You can test your GCM functionallity with my test gcm server. Hope, this help you.
I'm developing a quite simple application that receives GCM's push notifications. There are similar questions here in SO, but this is the only one I found that tries to update the ListView in the onNewIntent() hook, but it wasn't helpful.
The "business logic" should be:
If a notification is received when the application isn't in foreground, add it to the ListView (so, the ListView will have only one item).
If a notification is received when the application is in foreground, add it to the ListView (so, it will have n>1 items).
This is the Activity that holds the ListView:

However, although the agregarNotificacion() method is called with the correct notification, it won't update the ListView items.
I did quite a bit googling, and read that methods like myAdapter.add() should be used, but it didn't work either (that's why I left it commented).
So, in this particular situation (creating the ListView in one Activity hook, and updating it in another), how could I refresh my ListView?
Two final considerations:
There's a small bug: if the application is run for the first time, and a push is received then, it won't be added (since the getNotificacionFromIntent() method is returning an object with null fields, instead of a null Notificacion). I'm aware of it, but running and exiting the app is a quick possible workaround.
Sorry for the "spanglish": this is a university project, so I'm using Spanish names in the variables and classes. But also, there's some copy-paste involved, that I haven't refactored yet.
Any help or direction will be highly appreciated.
Regards.
The solution was to extend from ListActivity, and sending the new items via: this.notificacionesAdapter.add(newItem).
I've been given access to the blogger API, I've confirmed that on my developer console.
I've also written some code to perform oAuth2 with Google Play Services using some of the code below.
String SCOPE ="oauth2:https://www.googleapis.com/auth/blogger";
GoogleAuthUtil.getToken(context, "myEmail#gmail.com", mScope);
It returns a token. As it should.
However, once I try to access the api using the token i get a error.
Unexpected response code 403 for https://www.googleapis.com/blogger/v3/users/self/blogs
Here is my request:
And here is my response:
Here is my BaseActivity.java code that gets the token:

I've been banging my head against the wall on this one. Anyone have any ideas?
Finally figured it out.
My build.gradle file somehow ended up having a different Application ID than my manifest. I changed it so they both match the manifest, and boom! it worked.
I have a strange issue which I cannot explain. In the manifest file the launch activity of my app is defined as follows:
<activity
android:name="com.xxx.xxx.xxx.StartupActivity"
android:label="#string/app_name"
android:theme="#android:style/Theme.Light.NoTitleBar"
android:screenOrientation="sensorPortrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
In the StartUpActivity the following check is performed:
protected void startIntent() {
Intent intent;
if (checkCurrentProfile()) {
Notifier.showHttpToast(R.string.toastLoggedIn);
//try to update the device token in the database
Request.updateDeviceToken();
intent = new Intent(this, GameListActivity.class);
} else {
intent = new Intent(this, RegisterActivity.class);
}
startActivity(intent);
finish();
}
So if the user has a valid account the GameListActivity is shown as root activity:
<activity
android:name="com.xxx.xxx.xxx.xxx.GameListActivity"
android:label="#string/app_name"
android:theme="#style/MyTheme"
android:screenOrientation="sensorPortrait" >
</activity>
The issue now is the following: sometimes the system brings the root activity to the front spontaneously without any user actions. It only occurs sometimes, but I can't figure out the cause. Can anyone help me out here?
The StartUpActivity looks like this:
public class StartupActivity extends StartupCoreActivity implements OnRegisterGCMListener {
private IabHelper mHelper;
private IabHelper.QueryInventoryFinishedListener mQueryInventoryFinishedListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
registerOnRegisterGCMListener(this);
if (!registerGCMneeded()) {
initInAppBilling();
}
}
#Override
public void registerGCMfinished() {
initInAppBilling();
}
private void initInAppBilling() {
boolean hasPremium = Prefs.getBoolValue(getResources().getString(R.string.pref_key_upgrade_premium), false);
if (hasPremium) {
//unlocking contents not needed
startIntent();
} else {
Prefs.storeValue(getResources().getString(R.string.pref_key_upgrade_premium), false);
mHelper = new IabHelper(this, C.Billing.BILLING_KEY);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (result.isSuccess()) {
queryInventory();
} else {
startIntent();
}
}
});
}
}
private void queryInventory() {
String[] products = {C.Billing.ITEM_SKU};
mQueryInventoryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
if (result.isSuccess()) {
checkPremiumVersion(inv);
} else {
startIntent();
}
}
};
mHelper.queryInventoryAsync(true, Arrays.asList(products), mQueryInventoryFinishedListener);
}
private void checkPremiumVersion(Inventory inv) {
if (inv.hasPurchase(C.Billing.ITEM_SKU)) {
Request.updPremiumVersion();
Prefs.storeValue(getResources().getString(R.string.pref_key_upgrade_premium), true);
Notifier.showHttpToast(R.string.toastPremiumContentsUnlocked);
}
startIntent();
}
}
And the StartupCoreActivity looks like this:
public class StartupCoreActivity extends Activity {
private final static int PLAY_SERVICES_RESOLUTION_REQUEST = xxxx;
GoogleCloudMessaging mGcm;
Context mContext;
String mRegId;
/**
* Substitute you own sender ID here. This is the project number you got

}

// Check device for Play Services APK.
if (checkPlayServices()) {
// If this check succeeds, proceed with normal processing.
// Otherwise, prompt user to get valid Play Services APK.
mGcm = GoogleCloudMessaging.getInstance(this);
mRegId = getRegistrationId(mContext);
if (mRegId.isEmpty()) {
registerInBackground();
return true;
} else {
// note we never called setContentView()
return false;
}
}
return false;
}

Intent intent;
if (checkCurrentProfile()) {
Notifier.showHttpToast(R.string.toastLoggedIn);
//try to update the device token in the database
Request.updateDeviceToken();
intent = new Intent(this, GameListActivity.class);
} else {
intent = new Intent(this, RegisterActivity.class);
}
startActivity(intent);
finish();
}
private boolean checkCurrentProfile() {
KUPlayer me = G.getMySelf();
if (me.getPlayerId() <= 0) {
//database was not present yet and has been created
//or database was present, but profile cannot be read anymore

return false;

return true;

super.onResume();
checkPlayServices();

I guess it has to do with the following known Android bug:
How to prevent multiple instances of an activity when it is launched with different intents
And as suggested put the following code in the onCreate method of the rootActivity:
// Possible work around for market launches. See http://code.google.com/p/android/issues/detail?id=2373
// for more details. Essentially, the market launches the main activity on top of other activities.
// we never want this to happen. Instead, we check if we are the root and if not, we finish.
if (!isTaskRoot()) {
final Intent intent = getIntent();
final String intentAction = intent.getAction();
if (intent.hasCategory(Intent.CATEGORY_LAUNCHER) && intentAction != null && intentAction.equals(Intent.ACTION_MAIN)) {
finish();
return;
}
}
I tested it and when you start your app from Google Play store in stead of launch screen, then indeed finish() is called from above code.

Above code for getting registration number please correct me anything wrong... but some time am getting duplicate notification.
thanks
You should use Canonical IDs for this. This might happen because you registered with several IDs for the same device. Using canonical IDs will set your ID to be the last registration you've made.
As per the GCM reference about this:
Canonical IDs
On the server side, as long as the application is behaving well, everything should work normally. However, if a bug in the application triggers multiple registrations for the same device, it can be hard to reconcile state and you might end up with duplicate messages.
GCM provides a facility called "canonical registration IDs" to easily recover from these situations. A canonical registration ID is defined to be the ID of the last registration requested by your application. This is the ID that the server should use when sending messages to the device.
If later on you try to send a message using a different registration ID, GCM will process the request as usual, but it will include the canonical registration ID in the registration_id field of the response. Make sure to replace the registration ID stored in your server with this canonical ID, as eventually the ID you're using will stop working.
More info here.
