Today I tested my app via Developer Sdudio platform. I found an issue with the Developer Studio.
When I created a component (ride4gGpio) in my project (ride4G), and start running Build Project, there are many Errors displaying in the Problems output window, you can see the screen shot:
But when I re-import the project an re-build the project, all of the issue was resolved.
Addition: my Developer Studio is v5.1.
