I had read the various solutions about WakeLock found here, such as adding Permission in the AndroidManifest.xml as well as ensuring the Constructor of GCMIntentService is set to public.
However, my code is still stuck at "Acquiring Wakelock"
The exact same code works seperately as an individual Android Application.
I am only encountering this error AFTER I integrate it into my Main Application.
The following are my code for GCM Intent Service:

GCM IntentService class: com.mp2012.ieatishootipostanalyzer.GCMIntentService
Acquiring wakelock
and it hangs....
Thanks !
Keep all the GCM
related class in the main package, i.e where u r calling gcm
registration. like this in your project package name com.mp2012.ieatishootipostanalyzer
.
It may be the case that there are lot more packages under the main package and the GCM
code need to put under another package. For example com.mp2012.ieatishootipostanalyzer.notification
. This also can be done but you need to edit the GCM code provided by google cloud message system. This is in the GCMBroadcastReceiver
:
protected String getGCMIntentServiceClassName(Context context)
{
String className = context.getPackageName() +".notification"+DEFAULT_INTENT_SERVICE_CLASS_NAME;
return className;
}
The the system will work.
