即使在服务被系统杀死后，Service 内部的线程也会继续运行

Question

my thread is basically a loop of some actions.

I have set a few checks in my loop, to check basically if a boolean is still true or false. The boolean is set to true when starting the service and set to false when the service is being stopped. More specifically, I set the boolean to false in onDestroy() method of my Service class.

Example:

  public class MyThread extends Thread{
   
    
private boolean active; 
    
public void setBoolean(boolean active)
    this.active=active;
    }
    }
    
    public class MyService extends Service{
    
    private Mythread mythread;
    
    @Override
    public void onDestroy()
    {
    mythread.setBoolean(false);
    }
    }

The issue is that when a Service is being stopped by the system, onDestroy() method is not called. So, how can I properly stop the thread when the service is no longer running?

Answer 1

It helps to know exactly what you mean by " when the service is being stopped ." I found 3 links related to your problem that I am sure will help to solve your issue (or at least to fully understand it):

TL:DR - If you are forcing stop, onDestroy() will most likely not get called.

• Android - Service - onDestroy() method not called when using Force Stop
• Is an android service guaranteed to call onDestroy()?

Even if the first helps, read through the rest.
