Conversion of 7z files to apk file format

Sometimes APKs (Android apps) downloaded from torrents or other websites have their extensions renamed from APK to some of the existing archive formats like ZIP, RAR, 7-z, TGZ etc., usually to bypass some kind of restriction or protection. You have to check out if your .apk file had just it extension renamed or if it was actually compressed, in this case to 7z.
