In this video I will finish the Android Contact App I started in the last video. The goal of this tutorial is to keep everything simple, but to teach numerous things.

I’ll show you how to create lists of contacts, which will contain a list of information on each contact. Will save these contacts to a database online. We’ll also be able to edit it from multiple screens. After this video you’ll be able to create lists of contacts, edit contacts and delete them, with everything stored online.

    Hello Derek. My one won't work properly when I try to update contacts and addresses. Its says "operation is list empty? cannot accept argument: [JDContacts]. For some reason it wont accept my tag for the webDB. Not sure what is wrong here.

    Derek I have a question. You think that C++ will be replaced soon (and if not, when you think ?) by other language (and which), in making games for consoles/PC ? Thx ^_^

    Hey:)
    I have a very old Android mobile phone. I think there is 2.X version on it.
    So here the question… On which versions does an app created on App Inventor work? And how can I set it so that the app works on that version?
    Sorry for the bad english.

    Hello Derek. I was thinking about making a security app. Which will do the following:

    – Whenever someone will turn on their mobile. The app will automatically detect if its them using the front camera.
    – If its them, nothing will happen. But if its someone else the mobile will automatically take a few pictures with the front camera.
    – There would also be an option to send those pictures to the owner of the mobile by email.
    – Also there will be an option to keep the app hidden from the app drawer.

    Can you just please tell me if it possible to make such an app using app inventor? So that i would waste my time in making it, if its not possible. Thank you.

    Hello Coach,
    Hope you are doing well.
    In any PRODUCTION environment there are many many Java/JSP/CSS/HTML files and many Config files which are  INTER- RELATED.

    It feels like being lost in a MAZE.
    How to know the LOGICAL FLOW of code in such a TOUGH case ?
    Can you please give a demo example ?
    Thanks for all you do have a nice week-end.

    Hi Derek, thank you for the videos. I made this app after watching your videos:
    https://play.google.com/store/apps/details?id=appinventor.ai_languagesenseiapp.LanguageSensei
    Could you please do a video on what to do after you have made an appinventor app. I tried researching on how to include ads and also how to include spaces in the name on Google Play, sadly to no avail. So my app is only found when I search for LanguageSensei.

    (I can see that the link I shared gave away  the new gmail account i used to develop with in the id. That's not secure.) 

    Thank you.
