Split APKs Installation Guide
Some apps are distributed as Split APKs (multiple .apk files packaged together) to optimize resources. Standard Android installers cannot open them.
About This App

On the puzzle, there's a band, consisting of 10 children, each with a musical instrument (bell wreath, triangle, maracas, cymbals, trumpet, guitar, violin, djembe, keyboard and saxophone). Use the app to scan the instruments. You hear the sound and see a photo of that instrument on your mobile device. By scanning the painting, you hear and see several instruments.
