I have read the Android docs, and I am not hopeful, but I thought I would give it a go anyways. Basically, the situation is that I have 2 apps. App A is a content manager that checks on a secured server for content files and downloads them to its storage on the Android device. App B (and any other apps that later may be needed) needs to view the content in App A's storage. Usually FileProvider
would be the way I go, but there's a problem with that.
Many of the content files are HTML documents with relative links. FileProvider
doesn't give access to every linked file to App B, so links are regularly broken. I am not sure, as it is not my project, if App A can be directed to download to a shared location either.
Is there a way to:
have App A grant what apps are allowed read access to its storage?
have FileProvider
grant general read access to a directory and all its sub-directories?
anything else someone might think of to get App B to view the files App A downloads?
or is this, as I fear, currently not possible due to Android restrictions?
Thank you.
As long as both your apps (A and B) are signed with same certificate then you can share resources between each other. This is a common practice within a lot of apps available at play store.
