 private void checkForUpdate() {
        PackageInfo packageInfo = null;
        try {      packageInfo=getPackageManager().getPackageInfo(DashboardActivity.this.getPackageName(), 0);
            int curVersionCode = packageInfo.versionCode
            if (curVersionCode > 1) {  // instead of one use value get from server for the new update.
                showUpdateDialog();
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
