Answer 1

With OS validation.

Call this in an AsyncTask

/** Retrieve the Android Advertising Id 
     * 
     * The device must be KitKat (4.4)+ 
     * This method must be invoked from a background thread.
     * 
     * */
    public static synchronized String getAdId (Context context) {

        if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT) {
            return null;
        }

        AdvertisingIdClient.Info idInfo = null;
        try {
            idInfo = AdvertisingIdClient.getAdvertisingIdInfo(context);
        } catch (GooglePlayServicesNotAvailableException e) {
            e.printStackTrace();
        } catch (GooglePlayServicesRepairableException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        String advertId = null;
        try{
            advertId = idInfo.getId();
        }catch (NullPointerException e){
            e.printStackTrace();
        }

        return advertId;
    }
