Xutils3——网络连接

1在build.gradle中引包

    compile'org.xutils:xutils:3.3.36'

2创建MyApplication初始化xutils

 public class MyApplication extends Application {@Overridepublic void onCreate() {super.onCreate();x.Ext.init(this);x.Ext.setDebug(BuildConfig.DEBUG);// 是否输出debug日志, 开启debug会影响性能.}

3在AndroiManifast.xml中声明权限并引入MyApplication

 <uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><applicationandroid:name=".base.MyApplication"

4 xml页面
