please use below function:

public static String registerClient(Activity activity) {
        String regId = "";
        String registrationStatus;
        try {
            // Check that the device supports GCM (should be in a try / catch)
            GCMRegistrar.checkDevice(activity);

            // Check the manifest to be sure this app has all the required
            // permissions.
            GCMRegistrar.checkManifest(activity);

            // Get the existing registration id, if it exists.
            regId = GCMRegistrar.getRegistrationId(activity);

            if (regId.equals("")) {

                registrationStatus = "Registering...";

                // register this device for this project
                GCMRegistrar.register(QwichesApplication.mContext,
                        CommonVariable.GCM_PROJECTID);
                regId = GCMRegistrar.getRegistrationId(activity);

                registrationStatus = "Registration Acquired";
                Log.d("tag", regId);
                // This is actually a dummy function. At this point, one
                // would send the registration id, and other identifying
                // information to your server, which should save the id
                // for use when broadcasting messages.

            } else {

                registrationStatus = "Already registered";

            }

        } catch (Exception e) {

            e.printStackTrace();
            registrationStatus = e.getMessage();

        }

        Log.d("tag", regId);

        // This is part of our CHEAT. For this demo, you'll need to
        // capture this registration id so it can be used in our demo web
        // service.

        return regId;

    }

this function returns gcm_id . i hope its useful to you...
