Context
Hema originally planned that the MMPK be rolled out via Google Play and sent to the devices, but encountered an issue in Android 12+ devices where it restricted putting files in other app folders, requiring the step of copying/moving the MMPK file from the device storage to the RT-app’s file folder.
The envisioned solution for this is an on-the-air updater where the RT-app itself will download the file from an Amazon AWS bucket that saves it directly to the RT-app’s file folder, making it directly accessible by the app for use.
Design
From the early design, a Check for updates button is available at the Settings screen References
