Follow this 7 step guide to create your first Android App
Android is no doubt a great platform for users as well as developers. Thanks to Android Studio
and continuous support from Google. And in case you were thinking to
begin creating Android apps but did not have much idea of the know-how,
you can follow this article to get your doubts clarified.
Programming Language
Android apps are developed in Java. You do not need to be an
expert, but you should be good in specific areas, e.g. you need to have
good knowledge of AWT and Swing for developing a GUI for your app.
Getting easy with following topics before starting will make the
development phase more enjoyable.
>> Event Handling.
>> Swing.
>> Constructors.
>> JDBC.
>> Classes, Objects and Methods.
>> Packages.
>> Abstraction.
>> Polymorphism.
>> Inheritance.

You’ll also need to learn basics of the Extended Markup Language(XML).

Steps to get an app built
1. Ideation
First of all an idea is required to be worked on. You’ll need to
have a clear view of what your app will be for and what it will do. A
good idea will be to start small and gradually add sophistication. Don’t
make it so boring that you don’t want to make it but try to avoid any
complex functions as far as possible. Ideally, the app will only require
one ‘screen’ (activity) and will involve some simple interactions so
that something happens when the user presses a button. Consider it a
challenge to make something that’s genuinely useful with the minimum
amount of code.
2. Choosing your IDE
The most common way to build Android apps is to use Android Studio
and Java. This is the official method recommended by Google and it will
afford you a lot of flexibility while ensuring there’s plenty of support
if things go wrong. This is also the method you will need to know if
you ever plan on becoming a professional developer.
There are numerous other options for your IDE and language too
however. You may pick Unity and C++ for instance if you want to make a
game. Basic4Android is an IDE focused on rapid development that lets you
code with BASIC rather than Java. There’s even an IDE that runs on
Android called AIDE.
3. Collecting Resources
Resources mean images and other material you will use in your app.
You can download numerous images and use them but be aware not to
violate someone’s copyright.
4. Building the layout of your app in IDE
Now you’re going to create your layout in Android Studio using the
‘designer’. This is a tool that lets you simply drag and drop the
widgets (also called ‘views’) where you want them on the page. You’ll
need to start a new project in Android Studio to do this but there will
still be no coding necessary at this point (except maybe a little XML).
To start a new project select File > New > New Project. Follow the
steps selecting a name for your project and for your activities and
choose ‘Empty Activity’.
5. Writing the core code
Now comes the more challenging part – adding the code. You know the
basics of Java and you have your widgets/views already in place. Now
you’re going to open the Java file for your main activity and simply
create some ‘onClick’ events to add code that will run only when users
click a specific button or otherwise take a specific action.
6. Implementing more complexity
By now though, you should have some of the basic functionality in
place so that your app responds to button clicks (in one way or another)
and perhaps stores some variables.
Next is to add the more advanced functionality that will be
specific to your app. For example, you might want your app to play music
when a button is clicked. Maybe you want to add some flashy animations.
Or perhaps you need to know how to transition from one activity to the
other.
7. Final review and publishing
Now comes the last step. You’ll have to test your app for bugs and
once everything is right you can get your app published on Google Play
Store.
