Error build android app

When ever I try to build my android application apk file I get the error message

Error building Player: Win32Exception: ApplicationName=‘C:/Users/public/AppData/Local/Android/android-studio/sdk ools\zipalign.exe’, CommandLine=‘4 “C:\Users\public\Documents\AndroidTestGame\Temp/StagingArea/Package_unaligned.apk” “C:\Users\public\Documents\AndroidTestGame\Temp/StagingArea/Package.apk”’, CurrentDirectory=‘Temp/StagingArea’

Please update to Unity 4.5.2, it resolves this issue (it’s a bug with Unity and the latest Android SDK).
