In order for the app to work, your phone must be on the same network as your development machine. Some corporate networks disallow communication between devices even on the same network. You can check connectivity by trying to access your app’s web interface from your device’s browser by trying to load http://<your-dev-machine’s-IP-address>:8080
If you happen to be using a Mac with Parallels, see here.
Thanks for your response…
I think it is not a connectivity issue, because I can see my “My App” on my mobile, but not the complete content.
For example: On my home screen, I just see the tabs, which i have implemented, but not the other features, which I have added. Do you have another idea regarding this issue?
Did you use the Mendix "Make It Native" App to test it, or did you try to test the native app with the normal Mendix "Developer App" like I did with the same error result?
