I am working on a project right now that can work way better if I am able to receive and save files from an Android app to the flash memory of an ESP32CAM and send said files back.

I have looked around but haven't really found anything on the matter. The Android app sends tthe messages through the Java intents and activities.

Does anyone have any idea how I can receive the file and save it to either flash memory or an SD card?
