What it is
A short episode of the Android Developers series on Android Development Patterns, presented by Ian Lake, about sharing text, HTML, files and images between apps. It covers ShareCompat for building share intents and FileProvider for granting URI-based access to files without storage permissions.

You are sending File URIs, with which Intent.FLAG_GRANT_READ_URI_PERMISSION does not apply and should not be used, as explained in this video [this video] and its accompanying blog post [LINK] . Other apps would need the storage permission to access your files. From the blog post: Instead, you can use URI permissions to grant other apps access to specific Uris. While URI permissions don’t work on file:// URIs as is generated by Uri.fromFile() , they do work on Uris associated with Content Providers [LINK] . Rather than implement your own just for this, you can and should use FileProvider [LINK] as explained in the File Sharing Training [LINK] .

Don't use file:// URIs for sharing. It requires the receiving application to have the READ_EXTERNAL_STORAGE permission. Instead use FileProvider [LINK] with external-path to allow the receiving app to access the file through your content provider without requiring special permissions.

You should check out the official training docs for sharing [LINK] . You should always expect content:// uri's like content://Download/5348 . Because your suppose to call getContentResolver().openInputStream(uri) . So you can just end up using the ShareCompat.IntentReader [LINK] .

Well, as I already said, you can't share a drawable because of the Sandbox (it is only visible to you app). You can have a look here to see a few ways on how you can share it ( [this video] ), but you have to store the file in the external storage. An alternative would ve something like this [LINK] but this approach is more of a "hack" than an actual solution. The proper way to do it is to save it on external storage and then use the path to share it.
