Hello, the nrfTooolbox app from Play Store runs on my LG K4 phone which has 5.1.1 Lolipop. If I load the Github project into my Android Studio and try to run it on the phone when compiled with Nougat 7.1.1 the uart app crashes, which I assume is normal. If I try to change the Compile Sdk to Lollipop, I get dependency errors " Error:(4) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'." Do you have the Project sructure setting used for the released App? It will help me fix the dependency errors. I assume this is the way to go.
