GCM error on app start

Question

This is my RegisterGCM class

 public class RegisterGCM {

private static final String PROJECT_ID = "589104089214";
// This tag is used in Log.x() calls
private static final String TAG = "otp_verification.";

// This string will hold the lengthy registration id that comes
// from GCMRegistrar.register()
private String regId = "";

// These strings are hopefully self-explanatory
private String registrationStatus = "Not yet registered";
private String broadcastMessage = "No broadcast message";

// This intent filter will be set to filter on the string
// "GCM_RECEIVED_ACTION"
IntentFilter gcmFilter;
Context ctx;

// textviews used to show the status of our app's registration, and the
// latest
// broadcast message.

// This broadcastreceiver instance will receive messages broadcast
// with the action "GCM_RECEIVED_ACTION" via the gcmFilter

public String getRegId() {
    return regId;
}

public void setRegId(String regId) {
    this.regId = regId;
}

public String getRegistrationStatus() {
    return registrationStatus;
}

public void setRegistrationStatus(String registrationStatus) {
    this.registrationStatus = registrationStatus;
}

public String getBroadcastMessage() {
    return broadcastMessage;
}

public void setBroadcastMessage(String broadcastMessage) {
    this.broadcastMessage = broadcastMessage;
}

public IntentFilter getGcmFilter() {
    return gcmFilter;
}

public void setGcmFilter(IntentFilter gcmFilter) {
    this.gcmFilter = gcmFilter;
}

public Context getCtx() {
    return ctx;
}

public void setCtx(Context ctx) {
    this.ctx = ctx;
}

public BroadcastReceiver getGcmReceiver() {
    return gcmReceiver;
}

public void setGcmReceiver(BroadcastReceiver gcmReceiver) {
    this.gcmReceiver = gcmReceiver;
}

public static String getProjectId() {
    return PROJECT_ID;
}

public static String getTag() {
    return TAG;
}

// A BroadcastReceiver must override the onReceive() event.
private BroadcastReceiver gcmReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (broadcastMessage != null) {
            // display our received message

        }
    }
};

public RegisterGCM(Context ctx) {
    super();
    this.ctx = ctx;
}

public void registerClient() {
    // TODO Auto-generated method stub

    try {
        // Check that the device supports GCM (should be in a try / catch)
        GCMRegistrar.checkDevice(ctx);

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

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

        if (regId.equals("")) {

            registrationStatus = "Registering...";

            // register this device for this project
            GCMRegistrar.register(ctx, PROJECT_ID);
            regId = GCMRegistrar.getRegistrationId(ctx);

            registrationStatus = "Registration Acquired";

            // 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.
            sendRegistrationToServer();

        } else {

            registrationStatus = "Already registered";

        }

    } catch (Exception e) {

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

    }

    Log.d(TAG, registrationStatus);
    // tvRegStatusResult.setText(registrationStatus);

    // 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.
    Log.d(TAG, regId);

}

private void sendRegistrationToServer() {
    // TODO Auto-generated method stub

}

// NOTE the call to GCMRegistrar.onDestroy()

public void onDestroy() {

    GCMRegistrar.onDestroy(ctx);

}

public void stop(Context ctx) {
    GCMRegistrar.unregister(ctx);
}

}

Here's what my LogCat shows when i launch the application

I have just started my app it does not have a gcm id so how can it recieve a message as in my logcat the last 2 line suggest and also my code for getting id is when i move to my login page. The app crashes the first time i start it and then when i start it again it runs smoothly without the above exception.

This looks like a known problem with a very old version of the GCM library. I would recommend updating to the latest version, as detailed here: https://developers.google.com/cloud-messaging/android/client
