我正在尝试在我的 android 应用程序中实现广告。当我将广告添加到我的 xml 布局时,我怀疑内存泄漏,所以我尝试了这篇文章中描述的方法:- Admob Memory Leak - 通过使用空活动来避免
广告已呈现并且没有问题,除了如果在我的应用程序屏幕之间,如果我不小心点击了设备的主页按钮,然后如果我转到最近的应用程序并选择我的应用程序,我会收到错误消息:-

我的 AdMobActivity 的启动模式是 singleInstance 所以也许这就是原因。我应该怎么做才能工作?
更新:-我的代码
在我的第一个启动活动(MainActivity)中
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
DatabaseAdapter databaseAdapter = new DatabaseAdapter(
getApplicationContext());
databaseAdapter.open();
databaseAdapter.close();
}
@Override
protected void onResume() {
super.onResume();
if (AdMobActivity.AdMobMemoryLeakWorkAroundActivity == null) {
Log.i("CHAT", "starting the AdMobActivity");
AdMobActivity.startAdMobActivity(this);
}
}
AdMob 活动:-
public final class AdMobActivity extends Activity {
public static AdMobActivity AdMobMemoryLeakWorkAroundActivity;
public AdMobActivity() {
super();
if (AdMobMemoryLeakWorkAroundActivity != null) {
throw new IllegalStateException("This activity should be created only once during the entire application life");
}
AdMobMemoryLeakWorkAroundActivity = this;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("CHAT", "in onCreate - AdMobActivity");
finish();
}
public static final void startAdMobActivity(Activity activity) {
Log.i("CHAT", "in startAdMobActivity");
Intent i = new Intent();
i.setComponent(new ComponentName(activity.getApplicationContext(), AdMobActivity.class));
activity.startActivity(i);
}
}
行号 16 是
throw new IllegalStateException("This activity should be created only once during the entire application life");
