How to implement events in a game using android events API (blueprint)?
I tried an achievement map but it seems to refuse to work.
Is this even possible in UE4?
I want to store information about ingame currency (events API does this as google claim) so that when local data is erased I could restore all currency information.
Yeah, you can do this by calling native method
Do you mean Nativizing Blueprints?
If so - sad 
I struggle with C++. Currently, I call PHP in my site by VaRest plugin to store information, I know this is not an efficient way but it is easier for me since I have zero to none knowledge in C++
