Just to inform all of you that I have my first app made in AppyBuilder. It’s a Sales Force which uses MySQL as the remote database. It’s has a very simple UI. I’m very happy with the results. Here some screenshots:
I won’t share the APK due a contract that I have with my client who is the owner of this app.
I would like to say THANK YOU to @Hossein, @Andres_Cotes, @CarlosPedroza27 and others that helped me a lot with my doubts.
