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

AndroidManifest
添加权限
<uses-permission android:name="android.permission.CAMERA" />
<!-- 用于写入缓存数据到扩展存储卡 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
注册provider
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
在res文件夹中新建xml文件：file_paths
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!-- 这个是保存拍照图片的路径,必须配置。 -->
<external-path
name="my_images"
path="." />
</paths>
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"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
在application中直接引用
<application
android:networkSecurityConfig="@xml/network_security_config"
..../>
