android – 允许Admob展示视频广告

我有一个完美显示插页式广告的应用程序,但它们只是图像,而且作为生活在视频上的一代,我认为让Admob也能展示视频广告也是有益的.

我是否必须为此添加额外权限？或者我应该做些什么？

以下是我展示广告的方式;

interstitial = new InterstitialAd(Main.this);
// Insert the Ad Unit ID
interstitial.setAdUnitId("ca-app-pub-...442");

//Locate the BAnner Ad in activity_main.xml

// request for Ads
adrequest = new Adrequest.builder()

// Add a test device to show Test Ads
.addTestDevice(Adrequest.DEVICE_ID_EMULATOR)
.addTestDevice("")
      .build();

// Load ads into BAnner Ads
//adView.loadAd(adrequest);

// Load ads into Interstitial Ads
Runnable r = new Runnable () {

    @Override
    public void run() {
          interstitial.loadAd(adrequest);
    }
};

runOnUiThread(r);
// Prepare an Interstitial Ad Listener
interstitial.setAdListener(new AdListener() {
  public void onAdLoaded() {
      // Call displayInterstitial() function
     displayInterstitial();
  }
 });

而这两个权限;

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

广告显示正常,但它们只是图片广告,我想要视频！
