I got a working example of a third party server to send push notifications to the device which is perfectly working in the Android emulators I use. As soon as I try to use it on my real device (Samsung Galaxy S) I don't receive my notifications anymore, even tough I reregister the device at the google server (as I use the same gmail account). I basically have no clue where to start looking as Logcat is not giving me any interesting information about it. The code is working in the emulator device, so my guess would be to start looking at the permission rules. Any ideas?
I don't know if this matters, but I am using Ubuntu 10.10 to develop/debug.
