Answer 1

If you want to use ads:adSize="SMART_BANNER" , you have to set android:layout_width is match_parent . Else, you can use ads:adSize="BANNER"

Answer 2

Add this to see if there are any errors.

mAdView.setAdListener(new AdListener() {
    @Override
    public void onAdLoaded() {

    }

    @Override
    public void onAdFailedToLoad(int errorCode) {
       ..  print the error code to see if there is one
    }

    @Override
    public void onAdOpened() {

    }

    @Override
    public void onAdLeftApplication() {
    }

    @Override
    public void onAdClosed() {

    }
});
