During building your Unity3d project for Android devices you might get following error::
"Error building Player: Win32Exception: ApplicationName='C:/Program Files (x86)/Android/android-sdk\tools\zipalign.exe', CommandLine='4 "D:\code\Game\Temp/StagingArea/Package_unaligned.apk" "D:\code\Game\Temp/StagingArea/Package.apk"', CurrentDirectory='Temp/StagingArea'"
To fix this error:
- Go to C:\Program Files (x86)\Android\android-sdk\build-tools\20.0.0 (you may have different version)
- Copy zipalign.exe to C:\Program Files (x86)\Android\android-sdk\tools\ (or in your Android SDK path)
