Unnable to make Google Cloud Messaging Work - google-cloud-messaging

Question

I followed the new tutorial Implementing GCM Client on Android, and I'm unnable to make it work.
I get the token form my device succesfully, and when I send the following message
{
"to": "f19jCbaw-S4:APA91b....",
"notification": {
"body": "body",
"title": "title"
},
"data": {
"message": "test"
}
}
to https://gcm-http.googleapis.com/gcm/send, I get the result:
{
"multicast_id": 844556567...,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "0:1433092445706613%..."
}
]
}
But my app is never entering into the the onMessageReceived of MyGcmListenerService class. The only clue that I have is the following log trace:
6399-6454/com.miapp.app W/GcmNotification﹕ Failed to show notification: Missing icon
I'm duplicated step by step the Google Cloud Messaging Quickstart sample project. Obviusly I use my api key and my sender id... but id does not work, my app never stops in my onMessageReceived method.
Anybody else is having this problem?

Answer 1

In fact the payload without notification should reach the "onMessageReceived" method and work fine, but if the notification is present into the payload, the same error is displayed "Failed to show notification: Missing icon".
I tried to set the icon inside the AndroidManifest.xml (on the both intent-filter, on the receiver), but nothing worked.
If you do not require notification, just remove them from the payload.
And if you need the notification, you need to add another required field inside the notification:
If your icon is inside the mipmap you can add:
"icon" : "ic_launcher"
if your icon is inside the drawable, you should have:
"icon" : "#drawable/ic_myicon"
So your new request would look like:
{
"to": "f19jCbaw-S4:APA91b....",
"notification": {
"body": "body",
"title": "title",
"icon" : "#drawable/ic_myicon"
},
"data": {
"message": "test"
}
}
