3.简单使用。

• 所需要的权限：

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

• demo：

public class MyApplication extends Application {    @Override    public void onCreate() {        super.onCreate();        //初始化        x.Ext.init(this);        // 设置是否输出debug        x.Ext.setDebug(true);    } }
