Learning to code can be a complicated and daunting experience. Most of the time it’s not even clear where to start, but you’ll probably have a slew of questions to answer before you even get started.
Learning about different types of languages gives you a fair idea of what kind of programming language you need to choose for different kinds of apps. Although Java is the official language, and Android app can be built with other languages. Since you’re interested in how to create Android apps predominantly, here are a few options to take into account.
If you want to develop Android apps, step one is picking a language. The differences between the various Android programming languages can be a little complex and nuanced. Choosing which one to start with requires an understanding of their individual strengths and weaknesses.
Below are the programming languages which are currently used for Android development:
Java – Java is the official language for Android development and is supported by Android Studio. It has a steep learning curve, however.
Kotlin – Kotlin is the most recently introduced Android language and the secondary official Java language; it is similar to Java, but in many ways, a little easier to get your head around.
C/C++ — Android Studio supports C++ with the use of the Java NDK. This allows for native coding, which can be handy for things like games. C++ is more complicated, though.
C# — C# is a slightly more beginner-friendly alternative to C or C++ that obfuscates more code. It’s supported by some very handy tools like Unity and Xamarin, which are great for game development and cross-platform development.
BASIC – A bonus option is to learn BASIC and try the B4S IDE from Anywhere Software. This is an easy but also really powerful tool, though definitely much more niche!
Corona/LUA – Another cross-platform tool build on LUA, it massively simplifies the app-building process and allows you to call native libraries.
PhoneGap (HTML, CSS, JavaScript) – If you already know how to build interactive web pages, then you can use this knowledge with PhoneGap to build a more basic cross-platform app.
The best way to develop an Android app is to go ahead and download Android Studio. This is a piece of software called an IDE, or Integrated Development Environment. It is offered as a package with the Android SDK, which is nothing but a set of tools used to facilitate Android development. This will give you everything you need in one place to get up and get going.
The official tutorials and documentation from Google are referred to in this method and you will find the largest number of libraries and free code to enhance your apps, and tutorials that focus on this method.
Life is much better with Android Studio, which has been gathering strength over the last few years. Features like the visual designer and suggestions make the process smoother, while advanced, powerful features are being added all the time to give developers access to things like cloud storage with easy implementation.
Java
For any mobile app developer around the world, the first and the most preferred programming language for an Android app in Java, one of the reasons being that it’s simply the official language of Android app development, which means it is one of the most supported languages by Google and the one that most apps in the Play Store are built with.
Java itself was developed by Sun Microsystems way back in 1995, and it is used for a wide range of programming applications. Java code is run by a virtual machine, which runs on Android devices and interprets the code.
Unfortunately, Java is also a little complicated and it’s not a great language to deal with if you are a beginner. This is the biggest hurdle faced by people who plan to get into Android app development. Java is an object-oriented programming language with confusing topics like constructors, null pointer exceptions, checked exceptions, and a lot more. It’s not terribly readable and you’ll use a lot of code for simple things.
If you add in the Java SDK, things might get more complicated still – a first-time coder can struggle to know what’s Java and what’s Android! Development using this route also requires a basic understanding of concepts like Gradle, the Android Manifest, and the markup language XML. There are a lot of communities in Java for this reason, and it’s also one of the most versatile and widely used.
So, is it the best programming language you need to learn? Definitely — especially for those who want the full Android development experience, diving into Java is the best place to start, if you ask me.
For those who are worried about complex code, it’s possible to work largely with the designer and follow tutorials for anything more complicated. But, if you’re a beginner and you’re looking forward to making a game, or you just want to start learning for the sake of learning and you’d like to get some rewarding projects off the ground, then I recommend you start with something easier and come back to this once you’ve got a bit more grounding.
Kotlin
Kotlin recently burst onto the scene as the “other” official language for Android development. Some speculations suggest that this was likely to raise the language’s profile and that it could possibly become the next Swift.
Just like Java, Kotlin runs on the Java Virtual Machine. It’s also completely interoperable with Java and doesn’t cause any hurdles or increase in the size of the files.
The main difference is that Kotlin requires less “boilerplate” code, which means that it is a more streamlined and easy-to-read system. It also does away with errors like null point exceptions and even excuses you from ending every line with a semicolon. This is a great programming language if you’re just learning to develop Android apps for the first time.
With that said, you know that Kotlin is definitely an easier starting point for beginners, and the fact that you can still use Android Studio is a big plus. It’s still not quite as simple to pick up as, say, C# with Unity, though, and the community support is in its relative infancy. In fact, you currently need to download a beta version of Android Studio in order to get out-the-box support.
But still, Kotlin should definitely be on your radar and could offer an easier entry point to “proper” Android development, which is likely why Google introduced it in the first place.
C/C++
If you ask me, it’s not really recommended to choose this route to develop an Android app. Android Studio offers support for C/C++ using the Android Native Development Kit. this means you’ll be writing code that doesn’t run on the Java Virtual Machine, but rather runs natively on the device and gives you more control over things like memory.
C#
C# is basically an easier, purely object-oriented version of C and C+ development by Microsoft. Microsoft’s basic aim was to bring the power of C++ and the ease of Visual Basic, and it reads a little like a simplified version of Java.
Unity
Unity is a “game engine,” which means it provides things like physics calculations and 3D graphics rendering and an IDE like Android Studio. It is an open-source tool, which makes it incredibly easy to create your own games, and the community is strong, which means you get a lot of support. With just a few lines of code, you have a basic platform game set up in less than an hour. It’s just perfectly powerful, being the tool used by most game studios on the Google Play Store. And it’s multiplatform, too.
BASIC
What we learned about C# was an attempt to offer the power of C with the ease of Visual BASIC. That’s because BASIC (Beginners All-Purpose Symbolic Instruction Code) is incredibly pleasant to use and an absolutely ideal jumping point for learning to code.
Unfortunately, it isn’t officially supported by Android Studio and you can’t use it in Unity or Xamarin. The good news is that there is a lesser-known option for developing Android apps in BASIC called B4A from Anywhere Software. This is an acronym for “BASIC 4 Android,” and as you might expect, it lets you code Android apps with BASIC. It’s certainly not the first choice for most programmers who want to develop Android apps, but it's always nice to have more options.
B4A is designed as a RAD, or Rapid Application Development environment. There are lots of other smart design decisions to make life easier, and there’s a very supportive community if you have any questions.
This is a great way to learn to code, and you can build some pretty powerful apps using this method alone. It’s not ideal for making higher-end games, though, and once again suffers from being an “unofficial” option, so it’s harder to create something that exactly meets the Material Design specifications, and you’ll find it harder working as a professional developer with only BASIC. The other big drawback is that this is the only option on the list that isn’t free.
Corona
Corona offers another considerably simpler option for developing Android apps while still giving you a fair amount of power and control. You’ll be coding in LUA, which is already much simpler than Java, and on top of that, the Corona SDK will make things even easier. It supports all native libraries, allowing you to publish to multiple platforms.
It is largely used for creating games but can be used in a variety of other ways, too. You’ll need to use a text editor like Notepad++ to enter your code and you can run said code on an emulator without even needing to compile it first. When you’re ready to create an APK and deploy, you’ll be able to do this using an online tool.
This does require basic coding skills, but it offers a nice and gentle introduction to the world of programming. At the same time, though, it is definitely somewhat limited and is a few steps removed from getting into “app builder” territory. This is more useful for someone who wants to create something relatively simple and isn’t as concerned about developing their coding skills or becoming a pro. If you want to use features such as in-app purchasing, then you’ll need to pay a fee. The same goes for using native Android APIs.
PhoneGap
Finally, the last major “simplified” option you can choose to develop Android apps is PhoneGap, unless you want to turn instead to an app builder program.
PhoneGap is powered by Apache Cordova and essentially allows you to create apps using the same code you’d normally use to create a website: HTML, CSS, and JavaScript. This is then shown through a “WebView” but packaged like an app. PhoneGap then acts as a bridge, allowing developers to access some basic native features of the phone or tablet, such as the accelerometer or the camera.
This isn’t really “true” Android development, though, and the only real programming will be JavaScript. For many basic tasks, it will do the job, but if you want to be able to claim true “Android app developer-hood” (that’s a thing)Feature Articles, then you should brave one of the other choices on this list.
