Android, looking for a simple way to accurately determine if a device is C2DM capable?

Question

I'm looking for the simplest way to write a boolean function that will tell me if the device the app is running on is capable of using C2DM.

I am aware that the presence of the Android Google Play app is guaranteed to ensure C2DM capability but not all devices have this and are still C2DM capable

As far as I can tell, The device needs to have the GSF installed (Google Services Framework) and a valid GMail account set up and these are the only requirements to guarantee C2DM will work. Is this accurate?

If so would a check for the existence of the GMail package and the Google Services Framework package be the best and most accurate approach?

Answer 1

Very quick an dirty but the concept remains, if you DO wish to simply search for the presence of the Google services framework you can use the below.

I only post this because AFAIK there isn't another obvious method.

 boolean installed  =   appInstalledOrNot("com.google.process.gapps");
        if(installed)
        {
                  System.out.println("App installed on phone");
        }
        else
        {
            System.out.println("App is not installed phone");
        }
    }
    private boolean appInstalledOrNot(String uri)
    {
        PackageManager pm = getPackageManager();
        boolean app_installed = false;
        try
        {
               pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
               app_installed = true;
        }
        catch (PackageManager.NameNotFoundException e)
        {
               app_installed = false;
        }
        return app_installed ;
}
