I am using coins in my Android game. You can collect coins while playing and purchase powerups using those. But the coin increases automatically to some previous high value on screen transition after I spend it on buying powerups. Suppose I have 100 coins and I bought a powerup for 40 coins. So now my coins are showing to be 60 which is supposed to. But if i went back to Main Menu or any other UI and if anything comes over screen like pressing the power button of device then unlocked phone again or any full screen ad appears or just minimizing the app and reopening it from recent apps list, then the value of the coins get increased automatically to 100 or 97 or 96 something like that. Please help me to fix the issue. Currently on BB 2.2.8 and exporting game for android OS.
