谷歌云消息发送通知，但我的设备从未被推送

Question

I'm trying to make a web app with push notifications. I'm using server key with no ip adress filtering so any ip is allowed (when I was adding my public shared ip from my server I was getting a 404 forbiden error...) Now it looks like it works, when I send a message I get this :

{"multicast_id":768704xxxxx3856470,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1430054xxxxxx71%60cd63d3f9fd7ecd"}]}{"registration_ids":["APAxxxea-Q0s5pbFZHpSu4BfKdabxxxxxxxxWjPGItVSc54U6_t7WsJme5Z5UjYldhry66rTHk95CUcRR7m2iAtfvPgTklbWlHn4YiDZi1Qxxxxxxxg9iz5jKMPiulvIQTTM5F16THVjw"],"data":{"message":"New content available!"}}

But I never receive a push in my device. I've been following tutorials form google and also form StackOverflow answers, but I'm still very noob in android and I'm sure there is something wrong in my code and I can't figure out what it is, any help would be greatly appreciated.

Answer 1

It will be hard to find the real solution without fixing your BroadcastReceiver implementation first.

It looks like you are following a deprecated sample. In the manifest, you no longer need the com.google.android.c2dm.intent.REGISTRATION action. Also, your receiver tag/entry should be outside the activity tag, and it should have an intent filter (your intent filter is outside the receiver tag).

Hope this leads you to a solution. You might want to follow this sample code instead.
