i have searched everywhere solution , looked @ similar non of them helped me.

use below lines of code

adview madview = (adview) findviewbyid(r.id.adview);  adrequest request = new adrequest.builder() .addtestdevice(adrequest.device_id_emulator)        // emulators .addtestdevice("ac98c820a50b4ad8a2106ede96fb87d4")  // galaxy nexus test phone .build();   madview.loadad(request ); 

instead of using this

adrequest adrequest = new adrequest.builder().build(); 

because line used when application ready publish on google play store.

you can place device's id in place of "ac98c820a50b4ad8a2106ede96fb87d4". code device id:

string android_id = settings.secure.getstring(getcontext().getcontentresolver(),             settings.secure.android_id);
