error with sdk folder

I was presented this problem

Error building Player: Win32Exception: ApplicationName=‘java.exe’, CommandLine='-Xmx1024M -Dcom.android.sdkmanager.toolsdir=“C:/Users/andrea/Desktop/filippo/APP/adt-bundle-windows-x86_64-20130917/android-sdk-windows ools” -Dfile.encoding=UTF8 -jar “C:/Program Files (x86)/Unity/Editor/Data/BuildTargetTools/AndroidPlayer\sdktools.jar” - ', CurrentDirectory=‘C:\Users\andrea\Desktop\filippo\lavori unity\provva’

can you give me a hand?
