Restricting App to Only Read Images/Videos from SD Card

[mac-ro-ni]

Hello Everyone,

I have a specific use case that I would like to implement. Currently, I know that the app allows including and excluding specific folders. However, I would like to programmatically restrict the app so that it only reads images and videos from the SD card (external storage).

Since I understand the app uses MediaStore for accessing media files, is there a particular place in the code where I can modify this behaviour to ensure only images and videos from external storage are accessed? Any pointers or insights on how to achieve this would be greatly appreciated.

Additionally, I’d love to get a bit more insight into the overall flow of the app. A brief explanation of how the app interacts with the MediaStore and handles storage access would be really helpful.

Thank you!

However, I would like to programmatically restrict the app so that it only reads images and videos from the SD card (external storage).

How would that be different from excluding the Internal storage? Excluding the folder in-app activates a different code path which is more or less same as blocking access directly in code.

Assuming you'll be using this app yourself, the easiest way to achieve what you want is by hardcoding whatever path you want to exclude in config.excludedFolders. In most cases, the Internal storage is located at /storage/emulated/0 so...

...you can replace HashSet() with hashSetOf("/storage/emulated/0").
