Answer 1

Error code is 3 stand for the ad request was successful, but no ad was returned due to lack of ad inventory.

The document is here https://developers.google.com/android/reference/com/google/android/gms/ads/AdRequest#ERROR_CODE_NO_FILL

You can implement this small function to get the knowledge of error code.

   private int getAdMobErrorCode(SampleErrorCode errorCode) {
    switch (errorCode) {
        case BAD_REQUEST:
        return AdRequest.ERROR_CODE_INVALID_REQUEST;
    case NETWORK_ERROR:
        return AdRequest.ERROR_CODE_NETWORK_ERROR;
    case NO_INVENTORY:
        return AdRequest.ERROR_CODE_NO_FILL;
    case UNKNOWN:
    default:
        return AdRequest.ERROR_CODE_INTERNAL_ERROR;
    }
}
