Does it work if you call LoadAd? Are you sure that AdView type is InterstitialAd?

Does it work if you call LoadAd?

Yes, without problems! As always, however, I can not reproduce the error with my test devices.

Are you sure that AdView type is InterstitialAd?

1. Catch this error with Try / Catch block.

2. Your code looks correct. The ad unit is set when you call Initialize.

Are you calling LoadAd multiple times? Make some tests and kill the activity and recreate it while the ad is loaded.

Are you calling LoadAd multiple times?

I call "LoadAd" in 3 different Activity each in "Activity_Create" 1 times.

Make some tests and kill the activity and recreate it while the ad is loaded.

Thanks, I have to try that.

Maybe also try using AdView1.Ready before you call AdView1.Show. Maybe there's a slight delay between when ReceiveAd is fired & it's actually ready.

If you're using Firebase Analytics you could log true & false results from AdView1.Ready - that way you can confirm (or not) if sometimes the ad isn't actually ready when ReceiveAd is fired.

Thanks for the tip, it looks better now.

Sub AdView1_ReceiveAd
    'Log("AdView1_ReceiveAd")
    If AdView1.Ready Then AdView1.Show
End Sub
