Android 拍照以及相册中选择(适配高版本)
|
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
动态申请拍照，读，写权限自定义弹出框调用系统相机拍照 3.1 调用系统相机申请拍照权限回调 3.2 拍照完成回调自动获取sdk权限 4.1 访问相册完成回调
具体实现
