        <Button
          title='Interstitial'
          onPress={this.showInterstitial}
          containerViewStyle={styles.interstitial}

        <AdMobBanner
          style={styles.banner}
          adSize='mediumRectangle'
          adUnitID={
            Platform.select({
              ios: 'ca-app-pub-3940256099942544/2934735716',
              android: 'ca-app-pub-3940256099942544/6300978111',
            })
          }
          testDevices={[AdMobBanner.simulatorId]}
          onAdFailedToLoad={error => console.error(error)}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  rewarded: {
    width: '100%',
    marginLeft: 0
  },
  interstitial: {
    width: '100%',
    marginLeft: 0
  },
  banner: {
    position: 'absolute',
    bottom: 0
  },
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

動作検証

android、iosともに表示された。

インステは動画じゃなくて静止画のみだった。(2020/7/20時点)

async-awaitを使う場合

AdMobRewarded.requestAd().then(() => AdMobRewarded.showAd());

上記を以下のようにもかける。functionをasyncで囲む

await AdMobRewarded.requestAd();
await AdMobRewarded.showAd();

バナーサイズ

adSizeに以下の通り設定する

banner	320x50
largeBanner	320x100
mediumRectangle	300x250
fullBanner	468x60
leaderboard	728x90
smartBannerPortrait Screen width x 32|50|90
smartBannerLandscape Screen width x 32|50|90
