/**

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();
}

安卓清单.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 onStart命令，没有错误日志

一些日志

我发现其他人像我一样的代码工作正常。 为什么我的代码不起作用。

这是对我的影响吗？

类加载器引用的未知路径：

Answer 1

类TestService的包是package com.mxyue.www.testdemo。在清单中也使用相同的：<service android:name="com.mxyue.www.testdemo.TestService"></service>
