适配 Android10 内部存储图片显示问题

外部存储将被废弃：filePath:/storage/emulated/0/com.aaa.bbb/图片
对应方法：Environment.getExternalStorageDirectory()
官方接口说明：https://developer.android.google.cn/reference/kotlin/android/os/Environment?hl=en#getexternalstoragedirectory
官方Android 10 隐私说明：https://developer.android.google.cn/about/versions/10/privacy/changes

期望路径文件路径：filePath:/storage/emulated/0/Android/data/com.aa a.bbb/files/Pictures/图片
对应方法context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);

引发问题：在相册无法显示已保存的图片
解决方案：可根据自己的情况做适配
