隐示意图启动服务，在Android 5.0之后必须外加指定启动服务的包名
intent.setPackage(“com.example.sj.servicedemo2”);
需在配置文件注册的seivice中增加意图过滤器

<intent-filter><action android name="com.wy.haha"/>;</intent-filter>

    Intent intent = new Intent("hehe.haha.houhou");        intent.setPackage("com.example.sj.servicedemo2");        this.startService(intent);

package com.example.sj.servicedemo2;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Toast;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    //隐式意图启动服务    //5.0之后，通过隐式意图启动服务。必须setPackage();    public void go1(View view) {        Toast.makeText(this, "启动了", Toast.LENGTH_SHORT).show();        Intent intent = new Intent("hehe.haha.houhou");        intent.setPackage("com.example.sj.servicedemo2");        this.startService(intent);    }    public void go2(View view) {        Toast.makeText(this, "终止了", Toast.LENGTH_SHORT).show();        Intent intent = new Intent("hehe.haha.houhou");        intent.setPackage("com.example.sj.servicedemo2");        this.stopService(intent);    }    public void go3(View view) {    }}

package com.example.sj.servicedemo2;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;

public class MyService extends Service {
public MyService() {
System.out.println(“MyService的构造器”);
}

//    @Override

// public void onStart(Intent intent, int startId) {
// super.onStart(intent, startId);
// }
//创建
@Override
public void onCreate() {
super.onCreate();
System.out.println(“MyService.onCreate”);
}

//启动时执行@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {    System.out.println("MyService.onStartCommand");    return super.onStartCommand(intent, flags, startId);}//销毁/停止时执行@Overridepublic void onDestroy() {    System.out.println("MyService.onDestroy");    super.onDestroy();}@Nullable@Overridepublic IBinder onBind(Intent intent) {    return null;}

}
