问题
When I'm using android c2dm to push notification to my devices, I have a strange problem.
If I'm closing application using "Manage apps->My application->force stop" and I try to send a push to my device, it doesn't work.
It works with all my other devices which have an Android version less than 4.0.
Any ideas?
Thanks
EDIT: Ok, I have investigated a little bit more, it seems that background code can not be run when an application is killed this way.
The system logs show me this:
05-09 11:43:15.450: W/GTalkService(25542): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE cat=[net.scimob.xxxxxx] (has extras) }
I don't know why it works on previous version of android and not 4.0 and more. Maybe google changed something in their code.
ps: When I use task killers, it doesn't use the same way to kill app and the c2dm push still works.
I hope this will help in the futur!

Correct. Don't do that.

This effect can be seen starting with Android 3.1. Apps when they are first installed, or are force-stopped, will not run again until the user manually launches some activity.
