    Default From a Java-program to an app on your phone

    Hello,

    I have a simple question, but I hope the answer will be simple too.. I have created a Java-program and it runs fine on a desktop or laptop computer. But now I want to create an android app of this Java-program. How do I do that?

    I have watched a video on Youtube, but it made me a bit dissapointed, because it looks like that all the lay-out work had to be done again... Maybe I'm wrong with that conclusion. The program that I used to make my Java-program is called 'Eclipse'. Now I'm afraid that this program is not qualified to make apps. In the Youtube video the guy used 'Adroid Studio'.

    I am not very experienced with programming in Java and I never made an app. So I hope someone can help me with this question.

    Yes. The GUI has to be completely rewritten. I have had very good luck copying the non-GUI code from desktop programs to Android apps. The GUI needs to be rewritten.

    I use Eclipse for my apps, but the current recommended/required IDE for apps is Android Studio.

    Start with a simple program that you find with a search on the internet. Build and test it to see what the steps are for Android development.
    Good Luck.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks for the quick answer. So unfortunately I was right about the GUI.. My program-script was 32 pages so there's a lot of work to do again. But I will start indeed first with a simple program so that I can find out how Adroid Studio really works.

    But your answer raises a new question. You said that you use Eclipse for your apps, but what kind of apps are they? Only for desktop and laptops or also for phones?

    My apps are for tablets. I'll send you a PM with a link to my Github entries.
