I have lenovo tablet: Bluetooth Wi-Fi Android 4.2.2 processor quadcore
So when I ever try to download brother in arms 2 from Googleplay it says doesn't complaitble with your device why?

Your android version is to old. Android is on Ver 5.0 lollipop now. If you don't have at least android 4.4.2 Kitkat your gonna see this problem a lot. I recommend upgrading you version. You can do this simply in the system settings > Check for software updates.
