Thank you very much! That is absolutely useful to know and I failed to find this information before on official resources. Although it does not explain the APK error, it points me to look for compatible alternative, which hopefully will work better together.
give a look in Android bundles, in Android Studio, i believe can us create apk with more one compilation to assegure all types of Android. Compile and distribute especific type of app for a correct Android version, then you use a framework7 v1,v2 or v3 and make a another app to Android 4.4.4. I dont make this, but i have that intention, im need to estudy more of that, hope help you.
