Xutils
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 {
@Override
public voidonCreate() {
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-permissionandroid:name="android.permission.INTERNET"/>
<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:name=".base.MyApplication"
