android怎么样检查，如果我的应用程序仍然是乳宁 [英] android how to check if my app is still runing

问题描述

我想建立一个处理程序或什么都来检查应用程序仍在运行，像

 而（appIsRunning）
 { //做一点事 }
做somthimg
 

解决方案

使用ActivityLifecycleCallbacks，使用这种方式：

 公共类MyApplication的扩展应用{     @覆盖
     公共无效的onCreate（）{
     super.onCreate（）;
     registerActivityLifecycleCallbacks（新MyActivityLifecycleCallbacks（））;
     }        @覆盖
        公共无效onTerminate（）{
         super.onTerminate（）;
        }        @覆盖
        公共无效onConfigurationChanged（配置NEWCONFIG）{
         super.onConfigurationChanged（NEWCONFIG）;
        }        私有静态final类MyActivityLifecycleCallbacks实现ActivityLifecycleCallbacks {      公共无效onActivityCreated（活动活动，捆绑软件包）{
       Log.e（，onActivityCreated：+ activity.getLocalClassName（））;
      }      公共无效onActivityDestroyed（活动活动）{
       Log.e（，onActivityDestroyed：+ activity.getLocalClassName（））;
      }      公共无效onActivityPaused（活动活动）{
       Log.e（，onActivityPaused：+ activity.getLocalClassName（））;
      }      公共无效onActivityResumed（活动活动）{
       Log.e（，onActivityResumed：+ activity.getLocalClassName（））;
      }      公共无效onActivitySaveInstanceState（活动活动，
        捆绑outState）{
       Log.e（，onActivitySaveInstanceState：+ activity.getLocalClassName（））;
      }      公共无效onActivityStarted（活动活动）{
       Log.e（，onActivityStarted：+ activity.getLocalClassName（））;
      }      公共无效onActivityStopped（活动活动）{
       Log.e（，onActivityStopped：+ activity.getLocalClassName（））;
      }
        }
    }
 

此方式可以检查每一个州和做任何事情...

I want to create a handler or what ever to check if the app is still running, something like

while(appIsRunning)
 {

 //do something

 }
do somthimg

解决方案

Use "ActivityLifecycleCallbacks" and use it this way:

    public class MyApplication extends Application {

     @Override
     public void onCreate (){
     super.onCreate();
     registerActivityLifecycleCallbacks(new MyActivityLifecycleCallbacks());
     }

        @Override
        public void onTerminate (){
         super.onTerminate();
        }

        @Override
        public void onConfigurationChanged (Configuration newConfig){
         super.onConfigurationChanged(newConfig);
        }

        private static final class MyActivityLifecycleCallbacks implements ActivityLifecycleCallbacks {

      public void onActivityCreated(Activity activity, Bundle bundle) {
       Log.e("","onActivityCreated:" + activity.getLocalClassName());
      }

      public void onActivityDestroyed(Activity activity) {
       Log.e("","onActivityDestroyed:" + activity.getLocalClassName());
      }

      public void onActivityPaused(Activity activity) {
       Log.e("","onActivityPaused:" + activity.getLocalClassName());
      }

      public void onActivityResumed(Activity activity) {
       Log.e("","onActivityResumed:" + activity.getLocalClassName());
      }

      public void onActivitySaveInstanceState(Activity activity,
        Bundle outState) {
       Log.e("","onActivitySaveInstanceState:" + activity.getLocalClassName());
      }

      public void onActivityStarted(Activity activity) {
       Log.e("","onActivityStarted:" + activity.getLocalClassName());
      }

      public void onActivityStopped(Activity activity) {
       Log.e("","onActivityStopped:" + activity.getLocalClassName());
      }
        }
    }

This way you can check each state and do anything...
