Hi, I was just doing the tutorials just fine but with running the app on a real device (Nexus 5). Went fine until this step. Any idea? New to Java and android development so bear with me. LogCat says

1,700 PointsResolved btw! :)

Courses Plus Student 1,741 PointsHow did you resolve it? I am having the issue even with a file downloaded from the tutorial, so it's not an issue with the code.

1,700 PointsHmm, when importing the project from Treehouse, it worked. But if it does't work for you, try the workaround mentioned in their description below. Hope it works out! (A lot of "work" words here)
Pablo Prado
Courses Plus Student 1,741 PointsYep, I had not seen the workaround; but it worked. Thanks!
