Question

MainActivity.java

package com.mxyue.www.testdemo;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.i("DemoLog", "beforetest startService");
        Intent intent1 = new Intent(MainActivity.this, TestService.class);
        startService(intent1);

        //stop Service
        Intent intent4 = new Intent(this,TestService.class);
        stopService(intent4);

        //restart Service

        Intent intent5 = new Intent(this,TestService.class);
        startService(intent5);

        Log.i("DemoLog", "aftertest startService");
    }
}

TestService.java

package com.mxyue.www.testdemo;

/**
 * Created by mxyue on 2017/8/13.
 */

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;


public class TestService extends Service{


    @Override

    public void onCreate(){

        Log.i("DemoLog","TestService -> onCreate, Thread ID:"+Thread.currentThread().getId());

        super.onCreate();

    }


    @Override

    public int onStartCommand(Intent intent,int flags,int startId){

        Log.i("DemoLog","TestService -> onStartCommand, startId: "+startId+",Thread ID: "+Thread.currentThread().getId());

        return START_STICKY;

    }


    @Override

    public IBinder onBind(Intent intent){

        Log.i("DemoLog","TestService -> onBind, Thread ID: "+Thread.currentThread().getId());

        return null;

    }


    @Override

    public void onDestroy(){

        Log.i("DemoLog","TestService -> onDestroy, Thread ID: "+Thread.currentThread().getId());

        super.onDestroy();

    }

}

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mxyue.www.testdemo">

    <application>
        ...
    </application>

    <service android:name="com.mxyue.www.testdemo.TestService"></service>

</manifest>

未调用onStartCommand，没有错误日志

一些日志

我发现像我这样的其他代码工作正常。为什么我的代码不起作用。

这是影响我吗？

ClassLoader引用了未知路径：

班级TestService的包是package com.mxyue.www.testdemo。也可以在清单中使用相同的内容：<service android:name="com.mxyue.www.testdemo.TestService"></service>

在Android Activity中启动服务，没有任何反应
