Discussion on SIM Card Manager with Admob

How I open the project in Android Studio?

I generated the apk file, the first time I’ve performed it worked, but after close and reopen it, no longer opens, get an error saying that the application has stopped.

What admob format I must choose? I’ve tried with interstitial but the ads are not displayed.

can u add interstitial ads?, i want to buy this.

Will this code fetch information from the dual sim mobiles and also from devices version 2.3 to latest?
