xUtils3的使用

MainActivity 主要是調用xutils3的各個方法

在導包那裡找到       
org.xutils:xutils:3.5.0      
        

 可以擷取網絡上的資料（get，post）
 可以擷取圖檔

配置這個       
import android.app.Application;
import org.xutils.x;

/**

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(this);
    }
