I\'m preparing to launch an app in the Play Store, and after experimenting with AdMob (in test mode with my device id), I am now wondering if I should remove the test device
Yes you should remove test mode before publishing:
AdView adView = (AdView) findViewById(R.id.ad); AdRequest adRequest = new AdRequest(); adView.loadAd(adRequest);
In onDestroy(): adView.destroy();
adView.destroy();
In layout:
In AdMob app settings select this: Disable test mode for all requests
