Android下Service入门

Service做为Android的5个基本组件之一，是很强大的，实现基本功能也并不复杂

Android下做个木马的话 用服务实现，是必须的，它可以后台运行，开始启动，下面实现简单的

1.在Eclipse中创建一个新的Android工程 HelloService

2.在ServiceAndroid项目->New->Class Package选择ServiceAndroid Name写MyService

3.打开MyService.java 输入如下内容

package Service.HelloService; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.util.Log; public class MyService extends Service { private boolean threadDisable; private int count; @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { super.onCreate(); new Thread(new Runnable() { @Override public void run() { while (!threadDisable) { try { Thread.sleep(1000); } catch (InterruptedException e) { } count++; Log.v("MyService", "Count is " + count); } } }).start(); } @Override public void onDestroy() { super.onDestroy(); this.threadDisable = true; Log.v("CountService", "on destroy"); } public int getCount() { return count; } }

4.修改 项目的 AndroidManifest.xml文件 加入一句 注册服务

<service android:name="MyService" />

5.修改项目主文件Service.java代码如下

package Service.HelloService; import android.app.Activity; import android.os.Bundle; import android.content.Intent; public class Service extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.startService(new Intent(this, MyService.class)); } @Override protected void onDestroy() { super.onDestroy(); this.stopService(new Intent(this, MyService.class)); } }

现在就完成了，开始编译 运行 Android模拟器出现后 打开LogCat 就可以看到调试的信息了。
