Question

I had the issue to display an image on AdMob Ad’s when no Ad could be loaded or is blocked by the user.
That occurs when the user has no internet connection for example or uses software to block ads.

Answer 1

I found the following answer to my question:

The link describes basically that you can react if the ad fails to load to show your own image using the method:

...

@Override
public void onFailedToReceiveAd(Ad ad, ErrorCode code)
{
    adView.setVisibility(View.GONE);
    customView.setVisibility(View.VISIBLE);

...

I hope it’s useful to some others.
