Conversion of zip files to apk file format

A zip to apk conversion is basically repacking of a ZIP archive to APK format used on Android. First of all, it's worth mentioning that .apk files are .zip files that had their suffix renamed from zip to apk. The internal structure of the .apk has a specific standard, so you can't just take any random ZIP archive and turn that into a proper APK file simply renaming the extension.

You can find apps that claim that they can help you convert zip to apk, like zip2apk converter, but such programs quite often just rename the files and conversion works not as apk Android package.
