When I try to build my xamarin android app with Xamarin Studio (or MS Visual Studio 2013) the build fails with error "cannot find symbol". The error source is an activity that is not from my project, but from previously opened project. The full path of the error file is "\obj\Debug\android\src\mono\TrialSplashScreen.java"
The error exists after clearing the project. The wrong activity does not exists and is not mentioned anywhere in my project.
I created my project from the scratch and copied all needed files - the error still exists.
Do you have any suggestions?
