Answer 1

In my case my banner ads have response code 3 on some devices with high API and especially with wide screen (I have used smart banner size), changing dependcy from com.google.android.gms.ads to com.google.firebase:firebase-ads (In case you are using Firebase) solved my problem.

Answer 2

The issues comes only if that particular app is suspended from playstore. Maybe you can try changing the package name and and also with new Admob Id.There is a chance that particular admob id can also be suspended due to compliances.

Answer 3

If you app support Designed for Families.

Bundle extras = new Bundle();
extras.putBoolean("is_designed_for_families", true);

AdRequest request = new AdRequest.Builder()
        .addNetworkExtrasBundle(AdMobAdapter.class, extras)
        .build();

Answer 4

Basically just try pass your test device id to adBuilder :

/** adRequest Object For test device */
AdRequest adRequest = new AdRequest.Builder().addTestDevice("TEST_DEVICE_ID").build();

/** adRequest Object For Production Device*/
AdRequest adRequest = new AdRequest.Builder().build();

You can find your test divece id in logCat after without test divece id adBuilder request:

I/Ads: Use AdRequest.Builder.addTestDevice("TEST_DEVICE_ID") to get test ads on this device.

Answer 5

If your AdMob account is only configured for banner ads and you're using interstitial ads, you may get this problem. My 2 cents.

Answer 6

I was testing on Galaxy S4, later my friend tested on Note 2 and it did not show the banner ad. Hence the problem was test device Id. If you are testing then make sure the test device ID is of the device you are testing on.
