Thanks for the reply. Lack of Google Play Services is a common trait of non-Google Android builds. I haven't looked at the GcmNetworkManager code to see what would be involved in adapting that, but apparently there is code in GcmNetworkManager that checks for Google Play Services and if not available reports "Google Play Services is not available, dropping GcmNetworkManager request." I don't know why Google Play Services would need to be available for GcmNetworkManager to do its thing, so was hoping that Qualcomm would work around that if possible. Or at least report why support for this feature isn't available.
