Unity Build Error

I am getting this error while building my app. can anyone please tell me about this issue,
Thanks

Error building Player: Win32Exception: ApplicationName=‘C:/adt-bundle-windows-x86-20140702/sdk ools\zipalign.exe’, CommandLine='4

It’s because of the new android SDK. They changed the folder structure and Unity can’t find the exe in the old place.

(The paths below are the default android sdk installation paths. Change them according to your installation folder)

You need to copy zipalign.exe from

C:\Program Files (x86)\Android\android-sdk\build-tools\20.0.0

to

C:\Program Files (x86)\Android\android-sdk ools
