Android admob插屏问题

cocos2dx版本:2.2.3

admob:google play services





以下是admob插屏广告创建的代码:



public void createInterstitial() {





// Create an ad.

_interstitialAd = new InterstitialAd(_activity);

_interstitialAd.setAdUnitId(AD_UNIT_ID);





// Set the AdListener.

//AdmobInterstitialDelegate delegate = new AdmobInterstitialDelegate();

_interstitialAd.setAdListener(this);





loadInterstitial();

}



public void loadInterstitial() {





// Check the logcat output for your hashed device ID to get test ads on a physical device.

AdRequest adRequest = new AdRequest.Builder()

.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)

.addTestDevice(“D2F0DD3A5275B8E6858EA483DD794D55”)

.build();





// Load the interstitial ad.

_interstitialAd.loadAd(adRequest);

}







以上代码是在oncreate里调用,但是没有在请求广告成功后立即将插屏广告显示出来,而是在出现某个场景后通过jni调用以下的方法来显示插屏广告。





public void showInterstitial() {

if (_interstitialAd.isLoaded()) {

_interstitialAd.show();

} else {

Log.d(“Interstitial”, “Interstitial ad was not ready to be shown.”);

}

}





但是,当在执行_interstitialAd.isLoaded()的时候却是出错了。

还请大神指点下!!!
