On 4.12.1 i often see following problem on my build machine. 4.10 was okay.
[Aapt] C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(752, 2): error MSB6003: The specified task executable "aapt.exe" could not be run. The filename or extension is too long
Is there any workaround for that ?
