Question

When I develop an Android application, how to exit this application? I try anything what I can do ,but I can’t exit my application what I am developing. How to do this ?
Any idea?

This my solution ,as folow,

public class SysApplication extends Application {
private List<Activity> mList = new LinkedList<Activity>();
private static SysApplication instance;

private SysApplication() {
}

public synchronized static SysApplication getInstance() {
    if (null == instance) {
        instance = new SysApplication();
    }
    return instance;
}

// When an activity is created  ,excute this method ,addActivity(activity) 
public void addActivity(Activity activity) {
    mList.add(activity);
}


      //When I want to exit this aplication ,excute this method ,exit()
public void exit() {
    for (Activity activity : mList) {
        activity.finish();
    }

    System.exit(0);
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    System.gc();
}

}

This can be useful for you : How to shutdown an android application?. There is method : Activity.finish() for closing activities.

Easy way is to press home button. It will put your app to the background and Android will take care of it.
