Appodeal ads not showing up

Integrated Appodeal in one of my app but ads are not showing up. I implement ads using a static class and than call the initialisation and display methods.
This helps in keeping all sdk codes in one place. for example

in MyAdsClass.java, I have a method for initialising and showing Appodeal ads, among others.

public void initAppodeal(Activity act){
Appodeal.initialize(act, “mysdkkeyforads”);
}

public void showAppodeal(Activity act){
Appodeal.show(act,Appodeal.INTERSTITIAL);
}

Now from my activities I call

MyAdsClass.getInstance().initAppodeal(this);
MyAdsClass.getInstance().showAppodeal(this);

But nothing shows up.

I use this method for AdMob, Airpush, MiniMob, MobileCore and others and those ads show up.
