How to Install Incompatible/Old App on Android [Without Root]
Installing an app via the Play Store is a straightforward process, and it is guaranteed to work on your device because the Store scans the undelying specificiation for your device and brings the exact same build of that app. Unfortunately, you cannot always be dependent on the Play Store, as there are a few instances wherein you might have to sideload the app from a third-party site. And this is where things begin to go south.

Chances are, you will hardly find the build of the app that will work straightaway on your device. Even if you find the APK that corresponds to your device’s chipset/processor, you might still face an issue or two.
