Cool [Q] Is this app defending itself?

Hey everyone,

Do any one know solution for this type of problem? Using 360Yunpan application for usage of 36TB of space but couldn't understand Chinese language so decided to decompile and recompile the app changing it to english language but unlucky its giving error saying this app is not the original application. Can any help me finding out the solution? If this trick is used in all other apks then probably it would be difficult to decompile apks. The screenshot info and errors of decompile and recompile are attached.

Thank You
