再发一次，java怎么调用android中的monkeyrunner

import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import com.android.monkeyrunner.adb.AdbBackend;
import com.android.monkeyrunner.core.IMonkeyDevice;
import com.android.monkeyrunner.core.TouchPressType;
public class MyTest2 {
private static IMonkeyDevice device;
private static AdbBackend adb;
public static void main(String[] args) {
// TODO Auto-generated method stub
if (adb==null){
adb = new AdbBackend();
// 参数分别为自己定义的等待连接时间和设备id
device = adb.waitForConnection(8000,"MSM8225QRD5");
}
//添加启动权限
String action = "android.intent.action.MAIN";
Collection categories = new ArrayList();
categories.add("android.intent.category.LAUNCHER");
// 启动要测试的主界面，主要是配置自己的包和启动类
device.startActivity(null, action, null, null, categories,
new HashMap(),"cn.com.fetion/.android.ui.activities.StartActivity", 0);
// 点击某一个坐标
device.touch(202,258,TouchPressType.DOWN_AND_UP);

}
}

java调用android的monkeyrunner 不理解？你想实现什么效果？
