Do Not Substitute File Size for Device Requirements
An app release label, a file size and a minimum operating-system requirement are different measurements. One cannot supply a missing value for another.
An app release label, a file size and a minimum operating-system requirement are different measurements. One cannot supply a missing value for another.
Read the field being described
A version name identifies a release label. An Android minimum-version field describes an operating-system threshold. File size describes the size of a particular file. None of these, alone, states all the memory, storage or hardware conditions that may matter.
Avoid invented conversions
Knowing a package’s size does not establish how much RAM a device needs. Nor does a small download prove that every Android phone supports it. Additional requirements need their own publisher evidence, tied to the relevant product and release.
When a specification is unavailable, leave that field unconfirmed rather than filling it with a familiar number from another app. The useful outcome is a correctly labelled set of facts, with gaps visible, instead of an apparently complete specification assembled from unrelated measurements.
An operating-system version is not a release number
A product label such as version 5 does not establish a requirement for Android 5. Those numbers belong to different naming systems. A requirements record should keep the app release, minimum operating system and available storage in separate fields. If only one is documented, reporting one reliable field is better than manufacturing the other two from its number.
