Load .apkx file into Android

An .apkx file is a collection of stuff one can download from a place like apkpure but then how do you install the application?

I recently downloaded duolingo to install on my Oukitel C8 and found that the solution was quite simple:

• Extract the files from the apkx file (an apkx file, like an apk file, is a zip format archive. In my case the filename was: Duolingo Learn Languages Free_v4.91.2_apkpure.com.xapk)
• The files are: com.duolingo.apk, config.armeabi_v7a.apk, config.xhdpi.apk, icon.png and manifest.json the last two files can be ignored.
• Use Android Debug Bridge (adb) to install the APKs all at the same time

Using install-multiple to get all those APKs on the device at the same time:

adb install-multiple com.duolingo.apk config.armeabi_v7a.apk config.xhdpi.apk

I also had to set "full screen mode" to allow the applicaiton to function properly... I don't know why.
