阅读更多关于 Android GCM doesn't work with wifi networks when 3G network is available

问题 I am developing app on Android GCM push notification. Everything works fine .But I am not able to get the notification message when my device is on wifi rather than on data plan of service provider. In my case data plan is 3G but and notification comes as usual to devices but when device is connected through wifi I am not able to get any notifications. 回答1: Well this should not be the case, I have an android app that receives GCM push notifications regardless it is connected via 3G or Wi-Fi.

How to keep Listening for Push Notifications on Android in the background

阅读更多关于 How to keep Listening for Push Notifications on Android in the background

问题 I am working on Push Notifications in Android. Now the issue is that I want to keep running my Push Notifications on the back ground as soon as the app start because I have no idea when the server will push the data to the devices. The main requirement is that our corporate app is having more than 10 activities and based on the notification received, I have to bring the related activity on the foreground so that user can preform action on that or do some silent action in the background

How to handle GCM changing the registration Id?

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

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 steps should be taken. Quote from Google - Although the com.google.android.c2dm.intent.REGISTRATION

C2DM Server with PHP 401 Error

阅读更多关于 C2DM Server with PHP 401 Error

I'm building my own C2DM application right now. I first started with a small Android application to test the push feature. And it works if I just call the curl command with the correct settings in my shell. Now for the server part I wanted to use PHP but as it seems I'm doing something wrong as I always get a 401 error message when I try to send a message to the client. First of all the code consists of two parts. The first curl request asks for the server token. This works I get a real response from google with a working token! The second curl request ends up with a 401 error message. Any

Android C2DM sleeping phone

阅读更多关于 Android C2DM sleeping phone

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 simply made something fundamentally wrong or did I misunderstand the C2DM push functionality? Can I
