活动不从最近的活动推出： - 安卓 [英] Activity Does not launch from the recent activities:- Android
问题描述
我想实现我的Android应用程序的广告。我怀疑是内存泄漏，当我加入广告到我的XML布局，所以我试图在这篇文章中介绍的方法： - <一个href="http://stackoverflow.com/questions/9558708/admob-memory-leak-avoiding-by-using-empty-activity">Admob内存泄漏 - 避免使用空活动
该广告的呈现并有不同之处在于，如果在我的应用程序的屏幕之间，如果我在设备的主页按钮点击意外，然后如果我去最近的应用程序，然后选择我的，我得到的错误没有问题： -

我AdMobActivity的启动模式是singleInstance所以也许这就是原因。我应该怎么做这个工作？
更新 - 我的code
在我的第一次发射活动（MainActivity）
公共无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.main）;
DatabaseAdapter databaseAdapter =新DatabaseAdapter（
getApplicationContext（））;
databaseAdapter.open（）;
databaseAdapter.close（）;
}
@覆盖
保护无效onResume（）{
super.onResume（）;
如果（AdMobActivity.AdMobMemoryLeakWorkAroundActivity == NULL）{
Log.i（聊天，启动AdMobActivity）;
AdMobActivity.startAdMobActivity（本）;
}
}
AdMobActivity： -
公开最后一类AdMobActivity延伸活动{
公共静态AdMobActivity AdMobMemoryLeakWorkAroundActivity;
公共AdMobActivity（）{
超（）;
如果（AdMobMemoryLeakWorkAroundActivity！= NULL）{
抛出新IllegalStateException异常（本次活动应在整个应用生命周期内只创建一次）;
}
AdMobMemoryLeakWorkAroundActivity =这一点;
}
@覆盖
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
Log.i（中的onCreate - AdMobActivity，聊天，）;
完（）;
}
公共静态最终无效startAdMobActivity（活动活动）{
Log.i（在startAdMobActivity，聊天，）;
意图I =新意图（）;
i.setComponent（新单元名（activity.getApplicationContext（），AdMobActivity.class））;
activity.startActivity（ⅰ）;
}
}
行没有。 16
抛出新IllegalStateException异常（本次活动应在整个应用生命周期内只创建一次）;
请看看这个code。我已经使用这个唯一的。我没有遇到任何内存泄漏。

希望这会帮助你。
与此code也一试。这并不在XML布局整合。只是做亲语法。

I am trying to implement ads in my android application. I suspected memory leaks when i added ads to my xml layout so i tried the approach described in this post :- Admob Memory Leak - avoiding by using empty activity
The ads are rendered and there is no problem except that if in between my app's screens, if i click on home button of the device accidently and then if i go to recent applications and select mine, I get the error :-

The launch mode of my AdMobActivity is singleInstance so maybe thats the reason. What should i do for this to work?
Update :- My code
Inside my first launch activity (MainActivity)
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);
}
}
AdMobActivity:-
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);
}
}
Line no. 16 is
throw new IllegalStateException("This activity should be created only once during the entire application life");
Please have a look at this code. i have used this only. i didnt faced any memory leaks.

hope this will help you.
have a try with this code also. this doesn't to integrate in xml layout. just do it pro grammatically.
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import com.google.ads.*;
public class AdmobExample extends Activity {
/** Called when the activity is first created. */
private AdView myAdView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myAdView = new AdView(this, AdSize.BANNER, "youradmob id. ");
//get layoutView
LinearLayout rootView = (LinearLayout)this.findViewById(R.id.rootViewGroup);
LinearLayout.LayoutParams layoutParams = new LayoutParams(480, 75);
rootView.addView(myAdView, 0, layoutParams);
AdRequest re = new AdRequest();
re.setGender(AdRequest.Gender.FEMALE);
//re.setTestDevices(testDevices);
//re.setTesting(testing)
myAdView.loadAd(re);
}
}
