Have problem when trying to build Android .apk 1. Reinstalled Unity 2. Reinstalled Android SDK 3. Full updated Android SDK 4. Reinstalled JDK I don't know what is wrong... have Windows 8

Please help, I bought couple of items from Assest Store, all working good on Windows build but I can't generate .apk even using blank project :/ Android SDK working good with eclipse and Phone Gap :/
