Android / iphone - Questions?

So I’m getting ready to make a android game and before I do I need some help.

(1) - How do you make a Save, So the player can store the data of the game
on to the phone.

(2) - I hear that if you uninstall or if I make a Update it will will delete your save is this true?

(3) - If (2 true) then how would you make it so people can buy coin,gem or other stuff in your game? (Because if someone buy something for $1 and can I Update or he/she uninstall the game lose it, it would be suck.

There are my Questions, I been thinking about this stuff for a long time and
I don’t want to see everything someone did in my game get lost, Hope you can help.

Thank you.

1)There are lots of questions regarding serialization. You can use System.IO to write plain data or .NET XML built-in serializers. Recently Unity added persistant data path variable in Application class pointing to external storage and making it easy to roam data along with SD card for user.

2)If you will change application identifier - yes, you will be unable to access old data. At least without pain and suffering. It is better idea to make sure you have set it correctly before deployment.

3)Sorry, no idea there, but I bet there are lots of this kind of questions answered already. Use search :slight_smile:
