android 10.0拍照显示并上传服务器

参考：
okhttp图片上传
Android 调用相机拍照，适配到Android 10
并在大佬的demo上增加了上传图片功能

10.0、9.0、8.0、6.0上试过了都能用。没试过 7.0

直接上代码:

AndroidManifest
添加权限

注册provider

在res文件夹中新建xml文件：file_paths

<?xml version="1.0" encoding="utf-8"?>

在app的build.gradle中引用

implementation 'com.zhy:okhttputils:2.6.2'

然后我运行的时候报错

java.net.UnknownServiceException: CLEARTEXT communication ** not permitted by network security policy

解决办法
在xml文件夹中新建：network_security_config

<?xml version="1.0" encoding="utf-8"?>

在application中直接引用
