Thread: 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.

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.

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?
