I have several .mapk files each for different apps that I would like to install at once.

For a normal APK this is easy enough to do looping with adb instead app.apk

When I try: adb install –user 0 app.apkm

I Get this: Performing Streamed Install
adb: filename doesn’t end .apk or .apex: apkm.apkm

I found online a way of installing from the extracted apps from the mapk?

Is there a way to install a .mapk file from adb/cli?

I hope this makes sense. Thanks for any suggestions
