安卓service相互唤醒保活

在第一个service里启动第二个service并绑定第二个service,当第二个service被杀死后在断开连接回调里再唤醒,第二个service做一样的操作

public class FirstService extends Service {

    private MyCon myCon;


    @Override
    public IBinder onBind(Intent intent) {
        //第4步，将自定义的Binder,在这里 return
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e("TAG", "本地服务启动");



        //第6步，new  一个自定义的连接对象
        if (myCon == null) {
            myCon = new MyCon();
        }
    }




    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        //第7步，当这个服务启动的时候，和远程服务绑定   bindService
        Intent intent1 = new Intent(FirstService.this, SecondService.class);
        FirstService.this.bindService(intent1, myCon, Context.BIND_IMPORTANT);
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.e("TAG", "本地服务注销");
    }





    //第5步，实现ServiceConnection 接口，实现它两个方法
    public class MyCon implements ServiceConnection {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.e("TAG", "连接远程服务成功");

        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
            Log.e("TAG", "连接远程服务失败");


            //这里是重点，当远程服务被杀死的时候，我们会在这里收到消息   然后重新启动服务，并且重新建立连接
            Intent intent = new Intent(FirstService.this, SecondService.class);
            //重新启动服务
            FirstService.this.startService(intent);
            //重新建立连接
            FirstService.this.bindService(intent, myCon, Context.BIND_IMPORTANT);
        }
    }

}

public class SecondService extends Service {

    private MyCon myCon;


    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e("TAG", "远程服务启动");
  
        if (myCon == null) {
            myCon = new MyCon();
        }
    }



    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Intent intent1 = new Intent(SecondService.this, FirstService.class);
        SecondService.this.bindService(intent1, myCon, Context.BIND_IMPORTANT);
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.e("TAG", "远程服务注销");
    }

 


    public class MyCon implements ServiceConnection {

        public void onServiceDisconnected(ComponentName name) {
            Log.e("TAG", "连接本地服务失败");
            Intent intent = new Intent(SecondService.this, FirstService.class);
            //重新启动服务
            SecondService.this.startService(intent);
            //重新建立连接
            SecondService.this.bindService(intent, myCon, Context.BIND_IMPORTANT);
        }
    }
