Custom apps should be moveable to the external SD card #374

Closed kelson42 closed 7 years ago

kelson42 commented 7 years ago

Kiwix releases pretty big custom apps (~1GB). Google plays allows only to downlaod the app on the main memory. Android allows only to move the app (and not any companion files) to the external SD card.

This is a problem because most of the people do not have a lot of free space on the main storage or do not want to keep it there.

The solution is not clear to me, but IMO we should provide - at least - a feature to move the whole app (main APK + companion file) to the external SD card. Hope this is feasible at all!

@kelson42 Well I guess its theoretically possible. We have write access to the .obb so we should just be able to provide an interface to copy it to another storage directory. Might be fiddly to implement correctly though and Google play likely wouldn't like it so might require a very hacky solution.

APK: Android itself has a tool to "migrate" an app to the ext SD card (at least on my Samsung device) and I believe to remember that many apps provide this kind of feature. So maybe the primitive is available in the Android SDK and we can use it to let Kiwix migrate itself.
OBB: Might be interesting to have a proof of concept (moving obb somewhere, and see how Android behave - update, uninstall, etc..).

Both might be "spike kind" CGI tasks maybe.

Duplicate of #8

@kelson42 I don't think we can achieve number one based on the nature of android. Number 2 sounds feasible however and might be suitable as a GCI task to create a proof of concept / fail and produce well written documentation on why it is not feasible.

@mhutti1 (1) OK, how work apps allowing to move apps to the SD card? Or does the problem is that the app can not move itself? (2) Sounds good.
