Finding the version of unity player used

It's kind of burdensome, but you can:

• Rename your apk file extension to rar (an APK is just a RAR file)

• Extract the file's contents

• Open any numbered asset file inside: assets/bin/Data with your hex editor

• Starting at the 21st byte ($14) there is a string telling the Unity version used to build

Thanks a lot for the response There are two different version number that i see, one in unity default resource and another different version (same across all other files) in rest of the files.

Which one should i consider
