If Android apps can't access other app code, how can one app check another for viruses?
I am trying to build an Android app to scan other apps for viruses or malware etc. But first I'm trying to figure out how existing antivirus scanning systems work.

I don't think rooting it, because there are many antiviruses that don't need rooting. If I have to guess, I would say that it scans the files for signature. And they gain access to files similar to the work of file explorers. Someone more knowledgeable can fix me.
