Feature Request: Retain state on Android close

[whs]

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

When RetroArch Android is closed by swiping up in Android task switcher, or automatically by the background task killer all progress in RetroArch is lost

Expected behavior

There should be an option (or always on) that flush in memory states to disk on activity onStop()

• Flush SRAM to disk
• If auto save state is on, make a save state
• Flush auto save state to disk

Looking at uwp/uwp_main.cpp App::OnSuspending it seems like similar behavior was implemented for UWP, but not Android

Actual behavior

Everything is lost when the app is killed in background

Steps to reproduce the bug

1. Play a game in Retroarch
2. Switch to 5 other apps
3. Android should've killed Retroarch at this point
4. Go back to Retroarch. It appears as fresh instance without the game running and all progress are lost
