Interstitial not loading.?

public class MainActivity extends ActionBarActivity {
InterstitialAd mInterstitialAd;
@Override
public void onBackPressed() {
    ShowAd();
    finish();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mInterstitialAd = new InterstitialAd(this);
    //mInterstitialAd.setAdUnitId(String.valueOf(R.string.interstitial_ad_unit_id));
    //mInterstitialAd.setAdUnitId(getString(R.string.interstitial_ad_unit_id));
    mInterstitialAd.setAdUnitId("ca-app-pub-6342248862135370/7323606247");
    requestNewInterstitial();
    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdFailedToLoad(int errorCode) {
            Toast.makeText(getApplicationContext(),"Ad Failed To Load", Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onAdLoaded() {
            Toast.makeText(getApplicationContext(),"Ad Loaded", Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onAdClosed(){requestNewInterstitial();}
    });
    //Load Ad Starts
    AdView mAdView=(AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
    //Load Ad Stops
}
public void second(View view){
    Intent i = new Intent(getApplicationContext(), second.class);
    startActivity(i);
}
public void ShowAd(){
    if(mInterstitialAd.isLoaded()){
        Toast.makeText(getApplication(), "The Ad has Loaded.", Toast.LENGTH_SHORT).show();
        mInterstitialAd.show();
    }
    else
        Toast.makeText(getApplication(), "The Ad has not loaded yet.", Toast.LENGTH_SHORT).show();


}
public void requestNewInterstitial() {
    AdRequest adRequest = new AdRequest.Builder().build();
    mInterstitialAd.loadAd(adRequest);
}

}

我的问题是它总是显示 toast "Ad failed to Load"。我不知道我的代码中缺少什么。请帮忙!!。我已经对此进行了很多搜索,所以请不要 post 链接到其他问题。

这就是您没有收到任何广告的原因。此时、地点和设备有 none 可供您使用。如果你想测试你需要设置测试 adUnitId。这也由 logcat:
