如何将图像从 ImageView 保存到 Android 共享存储？ 当用户卸载应用程序时，我不希望我的图像被删除

Question

I want to store my file in android Shared Storage. All the ways I have found store image in internal storage which I don't want because internal storage will be deleted when user uninstall the app. A code would be helpful which store the image from ImageView to shared storage. I have tried reading android documentation but I don't understand what's written there.
