Gcm Launch Background/closed App When Get Notification (android)

I have a problem with GCM. I created a server side notification pusher (in PHP), that send to specific user (based on location) who have the app, a notification. I have three cla

Solution 1:

OK,

I just fixed the problem.

The JSON i send is like :

"notification":{
    "body":"blabla",
    "title":"one title""icon":"notification_icon"
},
"data":{
    "body":"blabla",
    "title":"one title"
},
"registration_ids":["id1", "id2", etc]

---

But this part (from the JSON) :

"notification":{
    "body":"blabla",
    "title":"one title""icon":"notification_icon"
}

was the problem.

I thought the JSONmessage is in two part, "data" when app is open, and "notification" when app is closed or in background. I thought that, because the app is closed, how can android know that he must show a notification ? So it's why use "notification" for specify that android must show a notification.

But no, "notification" is used for send simple notification without action.

So i resolve the problem by sending this JSON :

"data":{
    "body":"blabla",
    "title":"one title"
},
"registration_ids":["id1", "id2", etc]
