I did someething to my project. I think it was wghen I was trying to clean up the code and moved somne of the files from my app to a share module. Android studio ver 3.0.1
When I try to build the project I get the following error Error:Execution failed for task ':app:preDebugBuild'.
Android dependency 'com.android.support.constraint:constraint-layout' has different version for the compile (1.0.2) and runtime (1.1.0) classpath. You should manually set the same version via DependencyResolution
