Answer 1

Check This code It may be help you :

protected void gcm() {
    // TODO Auto-generated method stub
    GCMHelper gcmhelper = new GCMHelper();
    String gcmtokenAlready = gcmhelper.alreadyregisterGCM();
    if(gcmtokenAlready.length()>0){

        To do code here

    }else{
        gcmhelper.registerGCM();
    }

//GCMHelper

public class GCMHelper {
private final String SENDER_ID = ContextProvider.getContext().getResources().getString(R.string.GCM_ID);
private final Context context = ContextProvider.getContext();
/**
 *  This method is used to register the device with the GCM.
 *
 * @param context the context
 */
public void registerGCM() {
    GCMRegistrar.checkDevice(context);
    GCMRegistrar.checkManifest(context);        
    GCMRegistrar.register(context, SENDER_ID);
}

/**
 * Already register gcm.
 *
 * @param context the context
 * @return the string
 */
public String alreadyregisterGCM() {
    GCMRegistrar.checkDevice(context);
    GCMRegistrar.checkManifest(context);
    return GCMRegistrar.getRegistrationId(context);
}

}
