1 - Error building Player: Win32Exception: ApplicationName='D:\SDK's\AndroidSDK\build-tools\23.0.3\aapt.exe', CommandLine='package --auto-add-overlay -v -f -m -J gen -M AndroidManifest.xml -S "res" -I "D:/SDK's/AndroidSDK\platforms\android-23\android.jar" -F bin/resources.ap_', CurrentDirectory='Temp/StagingArea'
