阅读更多关于 Android C2DM message received confirmation at App Engine side

问题 Is there a way I can get the information whether the c2dm message was sent to a device or still in queue somewhere on App Engine side? The device won't get the messages if it's on some WiFi access point (random behavior). I want to implement time limit to the notification messages. If the time is up, the messages make no sense anymore and should never be delivered. 回答1: You shouldn't be sending information, however small, directly to your users through C2DM.

阅读更多关于 How to handle GCM changing the registration Id?

问题 I was wondering how will app/device be notified if GCM server decides to refresh the registrationId which the app previously retrieved from the GCM server. Currently, I save the 1st retrieved registrationId and save it in the database and send this registrationId to App server. So, from next time App won't be talking to GCM server. In this case App will never know if the registrationId is changed by GCM server. Google document suggest something to handle the case, but it does not mention what

问题 According to this Android C2DM keeps a socket alive with a heartbeat mechanism, making it able to receive push messages. This made me hope I could deliver messages to sleeping phones with an active wifi connection. I've made an implementation setting the "delay_while_idle" to '0'. The message is delivered if my phones' screen is powered off, but not if the phone goes to sleep (tested with intervals 20mins, 1-6 hours). I have acquired a partial cpu lock + a full wifi lock just in case. Have I
