IONIC 3 - Admob Free not displaying Ads when testing is false

Finally I solved this issue!

Since my code seemed to be right, as the test Ads were working, I went back to my Admob account and found out that I had missing payment info.

As soon as I added my address on the payment page, my live Ads started being served.

I have tested my app on Android (emulator and device) and IOS (emulator only) and the Live Ads are being served with no problem on both.

App with loaded Ads

Bro sorry for not helping you but from 3 days a go i don't know why my ionic doesn't work after installing admob-free this is the error i got while building app :

Dex: Error converting bytecode to dex: Cause: PARSE ERROR: class name (com/google/android/gms/base/R) does not match path (Com/google/android/gms/base/R.class) ...while parsing Com/google/android/gms/base/R.class
