Once saving is done it will then trigger an Intent.ACTION_SEND so user can share the recently save image with some description to social apps and compose a email with GMail. This code snippet works fine. try { //Get primary storage status String state =

问题 In my Android app, I need to expose some file from a FileProvider.
