当有人点击广告后返回时，Android 应用程序不会恢复

Question

当有人点击广告并返回应用时，应用不会恢复。我在 mainfest 中添加了 android:launchMode="singleInstance" 并在 list 的 Activity 声明中添加了 android:alwaysRetainTaskState="true"。

我不知道哪里出错了。

我的 .java 文件代码如下:

 public class MainActivity extends Activity implements AdListener{

 public static int count=0,dispad=0;
 public static LinearLayout lay1;
 private static final Class<?>[] NUMBERS = {First.class};
  protected AdView adView;
    View admobAds;


   @Override
    protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
adView = (AdView)findViewById(R.id.ad);

Toast toast = Toast.makeText(getApplicationContext(), "Click on the ad to      
       make        it     disappear" +
            "", Toast.LENGTH_LONG);
    toast.show();

 adView.loadAd(new AdRequest());

 lay1=(LinearLayout)this.findViewById(R.id.mainlay);

 admobAds = (View) findViewById(R.id.ad);

   //More code 

    public void onDismissScreen(Ad arg0) {

    lay1.removeView(admobAds);
    dispad=1;
    // TODO Auto-generated method stub

}
   }
