activity_main.xml私はどのように私のアンドロイドアプリにIDを生きているadmobを得るのですか?
public class MainActivity extends AppCompatActivity {
private AdView mAdView;
private Button btnFullscreenAd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.build();
mAdView.loadAd(adRequest);
