    HashMap<String, Object> defaultsRate = new HashMap<>();
    defaultsRate.put("new_version_code", String.valueOf(getVersionCode()));
    mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
    FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
            .setMinimumFetchIntervalInSeconds(10)
            .build();

    mFirebaseRemoteConfig.setConfigSettingsAsync(configSettings);
    mFirebaseRemoteConfig.setDefaultsAsync(defaultsRate);

    mFirebaseRemoteConfig.fetchAndActivate().addOnCompleteListener(this, new OnCompleteListener<Boolean>() {
        @Override
        public void onComplete(@NonNull Task<Boolean> task) {
            if (task.isSuccessful()) {
                final String new_version_code = mFirebaseRemoteConfig.getString("new_version_code");

                if(Integer.parseInt(new_version_code) > getVersionCode())
                    showTheDialog("com.facebook.lite", new_version_code );
            }
            else Log.e("MYLOG", "mFirebaseRemoteConfig.fetchAndActivate() NOT Successful");

        }
    });
}

private PackageInfo pInfo;
public int getVersionCode() {
    pInfo = null;
    try {
        pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
    } catch (PackageManager.NameNotFoundException e) {
        Log.i("MYLOG", "NameNotFoundException: "+e.getMessage());
    }
    return pInfo.versionCode;
}



private void showTheDialog(final String appPackageName, String versionFromRemoteConfig){
    final AlertDialog dialog = new AlertDialog.Builder(this)
            .setTitle("Update Available")
            .setMessage("This version is Old, please update to version: "+versionFromRemoteConfig)
            .setPositiveButton("UPDATE", null)
            .show();

    dialog.setCancelable(false);

    Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
    positiveButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {
                startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse("market://details?id=" + appPackageName)));
            }
            catch (android.content.ActivityNotFoundException anfe) {
                startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
            }
        }
    });
