Installed APK, wont work

[SamsungMasterRace]

Hi all,
I installed an APK for an app (Air tycoon 4) to get unlimited cash. Whenever I open it, it gets stuck on loading screen. Works fine without apk. Help?
Thanks

I got it from a third party website.

Hi !
I think the version is not the right apk of the company or the Android version in your phone is not compatible

The apk is not legit. It may be compromising other aspects of your phone as well.
