// The app consists of MainActivity.java and SearchResultFragment.java at which I don't want to show Ads and few other fragemnt with Ads.
// The Appodeal bottom banner is handled only in the Activity.
// In onCreate() method there is initilization:

Appodeal.initialize(this, appKey, Appodeal.INTERSTITIAL | Appodeal.BANNER_BOTTOM);

// and then call for showing bottom banner

Appodeal.show(this, Appodeal.BANNER_BOTTOM);

// in onResume I call:

Appodeal.onResume(this, Appodeal.BANNER_BOTTOM);

// In MainActivity I created public methods for showing/hiding apps (I know that interface is better option, but it also don;t work this way)

public void showAds() {
  Appodeal.show(this, Appodeal.BANNER_BOTTOM);
}

public void hideAds() {
  Appodeal.hide(this, Appodeal.BANNER_BOTTOM);
}

// For the SearchResultFragment itself in Oncreate I'm hiding the ads:

((MainActivity) getActivity()).hideAds();

// In onStop method I'm trying to show the ads:

((MainActivity) getActivity()).showAds();


// To sum up, ads are hiding, but after that, calling showsAds(); does not seem to work (it is invoked though).
