when I go into settings -> downloaded ->
and I look under “Storage”
I see: Total, Application and Data.
Where does it get Application from. If I look under /data/data/com.company.app, I can see the data storage, but for Application, if I look under /data/app/com.company.app.apk — the install image, but that’s not the same size as what settings Application Info reports…
Does Android run straight from the apk/zip file or does it expand it somewhere and run from there?
The apps don’t run directly from the .apk, they are decompressed and JIT-compiled to the “Dalvik cache”
