Android服务一 创建启动服务

启动服务

基于Service

package service;

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

/**
* 创建启动服务
*/
public class MyService extends Service {

@Override
public void onCreate() {

}

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

return 0;
}

@Override
public IBinder onBind(Intent intent) {

return null;
}

@Override
public void onDestroy() {

}

}

String address = "https://img-blog.csdn.net/20160527205804527";
Intent intent = new Intent(this, MyService.class);
intent.putExtra("address", address);
startService(intent);

基于IntentService

package service;

import android.app.IntentService;
import android.content.Intent;

import HttpURL.HttpUtil;

/**
* 使用IntentService创建启动服务
*/
public class StartIntentService extends IntentService {

public StartIntentService() {
super("Download Picture");
}

@Override
protected void onHandleIntent(Intent intent) {
HttpUtil.downloadPicture(intent.getStringExtra("address"));
}
}

String address = "https://img-blog.csdn.net/20160527205804527";
Intent intent = new Intent(this, MyService.class);
intent.putExtra("address", address);
startService(intent);
