[Q] How to make an app that requires android 4.4 or more run on a lower version?

I have a custom rom with Android 4.2.2 on my Gionee Elife E6 and I've been trying to install an .apk file for 3 days now, only to get the "There was a problem parsing the package" error. It took me 2 days and another device with Android 4.4 to realize the application has an Android version restriction. I've been searching the web for 3 hours now and I can't seem to find any help in changing the app's requirements, and while browsing the apk's files I cannot seem to find any file to have a code line about android version restriction. Can I get some help please? I am so desperate to get this app working right now
