Android 拍照以及相册中选择(适配高版本)————上传头像并裁剪(一)

前言

       在项目研发中，相信大家都遇到过给用户增加头像照片的需求。

       随着手机版本的不断更新，Android 8、android 9、android 10、android 12、android 13、鸿蒙系统等等；遇到这个功能需求，大家肯定会想，“这还不好写？ 之前就已经写过了。” 把老项目跑了一遍之后发现无法运行。要不大多数就会出现奔溃的情况！

       这也就遇到常见的 高版本适配情况，以及针对不同版本该如何处理？

       碰到这种情况也不要慌张，博主将为大家推出两篇热乎连载篇。从两个不同开发场景下，来给大家分享两篇文章，来更加详细的了解该如何去实现？【特此来记录】

       本篇将为大家详细讲解如何调用摄像头拍照 & 选择相册，并裁剪图片。

效果

实测android 8、android 9、android 11、android 13、鸿蒙系统均有效；
手机机型分别为OPPO、华为、VIVO手机。

对于效果演示，将单独拿出两个来举例：

• VIVO android 13
• 华为 鸿蒙系统2.0.1

vivo	华为

功能

1. 动态申请拍照，读，写权限
2. 自定义弹出框
3. 调用系统相机拍照
   3.1 调用系统相机申请拍照权限回调
   3.2 拍照完成回调
4. 自动获取sdk权限
   4.1 访问相册完成回调

具体实现

.gradle配置文件：

AndroidManifest文件：

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

<provider      android:name="androidx.core.content.FileProvider"      android:authorities="com.harry.takepicture.provider"      android:exported="false"      android:grantUriPermissions="true">          <meta-data             android:name="android.support.FILE_PROVIDER_PATHS"             android:resource="@xml/filepaths" /></provider>

filepaths.xml文件：

<?xml version="1.0" encoding="utf-8"?><paths>    <paths>        <external-path            name="camera_photos"            path="" />    </paths>    <external-path name="rc_external_path" path="."/></paths>
