I dont know how to fix this but it showed up after I integrated google play services into my project. The error is:
Error building Player: Win32Exception: ApplicationName='C:\Program Files (x86)\Java\jre7\bin\javac.exe', CommandLine='-bootclasspath "C:/Program Files (x86)/Android SDK/adt-bundle-windows-x86_64-20140702/sdk/platforms/android-21\android.jar" -d "C:\Users\Shay\Documents\Flappy Rotation\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding UTF-8 "com\google\example\games\basegameutils\R.java" "com\UltimateStudios\ChickenWings\R.java"', CurrentDirectory='C:\Users\Shay\Documents\Flappy Rotation\Temp\StagingArea\gen'
Any suggestions would be very helpful.
