While working on a little project that integrates with GCM, I've stumbled across a bit of a strange issue.
Some times when I start watching the log to see if messages are received, messages do not appear to be coming through until I have changed the network state (I.E. originally on WiFi, if I turn off WiFi and move to Mobile Data, the messages arrive fine). After I've changed the network state, messages start to arrive perfectly fine, and the same applies once I change the network state back to what it was before (in this case, WiFi) the messages continue to be received.
The project itself includes the ability to start on boot (starts the GCMBaseIntentService on boot), which again works perfectly fine, and I'm sure the app / service is running as I've manually started up the app when this issue occurs (which also checks to see if the service is running, and if it's not it runs it and checks to see if it's registered).
Has anyone else come across this issue, or has any pointers as to how I could resolve this? I'm not seeing anything of much help in the log between the time messages are not being received and when they are (after changing the network state). I've gone through the GCM docs and can't see any mention of messages not being received due to a time-out (on the device itself), or any config options that might affect this.
Appreciate any assistance - I can provide source if needs be, although it hardly deviates from the demo app provided in the android-sdk.
