Question

当我按下＆＃34;启动服务＆＃34;我想在背景中运行一些应用程序。即使应用程序关闭或被杀，也会继续在后台运行。为此，我使用START_STICKY并且它可以工作，但问题是当我想要终止服务时 - 应用程序已关闭（就像我想要的那样）然后我得到错误（不幸的是，流程服务已经停止）。并且该服务尝试再次运行。

我如何停止服务？

P.S-I在网上搜索解决方案但未成功。

我的代码

MainActivty

public class MainActivity extends AppCompatActivity {
    private TextView textView;
    private  Intent i;
    private static Button killSerBut;
    private static final String TAG="com.example.elicahi.service";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView=(TextView) findViewById(R.id.textView1);
        killSerBut=(Button)findViewById(R.id.kill);
        killSerBut.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG,"onClick");
                textView.setText("OnClick");
                killServ();
            }
        });
        //start the service
       i= new Intent(this, MyService.class);
        startService(i);

    }



    public void changeText(String msg)
    {

        textView.setText(msg);

    }
    public void killServ()
    {
        finish();
        Log.d(TAG,"OnStop");

        MyService myService=new MyService();
        myService.stopService(i);
    }
}

为MyService

    public class MyService extends Service {

        private static final String TAG="com.example.elicahi.service";
        private Intent intent;

        public MyService( ) {


        }


        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            Log.d(TAG, "onStartCommand method called");
            Runnable r= new Runnable() {
                @Override
                public void run() {
                    for (int i=0; i<10;i++){
                        long waitFor= System.currentTimeMillis()+1000;
                        while (System.currentTimeMillis()<waitFor){
                            synchronized (this){
                                try{
                                    wait(waitFor-System.currentTimeMillis());
                                    Log.d(TAG, "the service is doing something");

                                }catch (Exception e){}
                            }
                        }

                    }
                }
            };
            //start the thread that inside the run nethod
            Thread elichaiThread = new Thread(r);
            elichaiThread.start();
            //if the service is destroy- then restart it
            return START_STICKY;


        }




        @Override
        public void onDestroy() {
            Log.d(TAG,"onDestroy method called");
            stopSelf();
        }





       /* public void killServ(Intent intGet)
        {
            Log.d(TAG,"Killed");
        intent=intGet;
        }*/

        @Override
        public IBinder onBind(Intent intent) {
            // TODO: Return the communication channel to the service.
            return null;
        }

}

那就是我的清单

  <service
                android:name=".MyService"
                android:enabled="true"
                android:exported="true" >
            </service>

logcat的

Answer 1

在Service标记

下的清单文件中使用属性

android:stopWithTask="true"

Answer 2

请替换此方法

public void killServ()
{
  stopService(MainActivity.this,MyService.class);
}

停止START_STICKY服务
