In which programming languages ​​is Android written

How to find the right programming language for Android apps

  • Java is clear:
    Due to the class system and the object orientation, no great ability to abstract is necessary.
  • Java is similar to the real world:
    Here, too, there are objects that are characterized by certain properties and with which certain activities can be carried out. This makes it easier to familiarize beginners with the principle of Java and offers an easy introduction to the world of app programming.
  • Java supports so-called multi-threading:
    With programs in this programming language, several processes can be carried out at the same time. This guarantees efficient execution of the apps, which significantly increases their performance.
  • It is platform independent:
    Java can run on any operating system, whether Windows, MacOS, Linux or another operating system. So if a larger team should be involved in the app development on several systems, this is not a problem.


This is where the major disadvantage of Java comes into play.
Independent programming on all platforms must be accomplished by a separate compiler. A compiler brings the generated code into the form that the respective system requires. Since the code is developed directly for the specific system in other programming languages, this step can simply be skipped there.
The use of a compiler reduces the speed of the programs enormously, which is why a different programming language for Android apps sometimes provides significantly more performance.

C and its variants

Another programming language for Android apps is C, which, unlike Java, is an imperative programming language. This means that in C and its numerous further developments such as C # or C ++ no objects are programmed on which the algorithms are executed, but simply a series of commands. By removing unnecessary objects from it, the code is made cleaner.


However, this also means that C is a more abstract programming language for Android apps. The empathy time is significantly longer and it takes a while until all commands and the syntax are understood.


In certain versions of C, such as C ++, the object orientation was also built in and is therefore more beginner-friendly. Many of the basic types, such as integers, are the same or at least comparable.

The small set of keywords and commands is an advantage of C. This helps with learning because so many different algorithms can be built with just a few commands.
In addition, C does not require a compiler, but can still be used on different operating systems. All that is needed is small, resource-saving programs that convert the code appropriately before use. There is little use of resources here, which makes C very quick and effective.

So you also have the option of programming an Android app with C, which is, however, not as common as app development with Java. C is a bit more difficult to learn as a programming language for Android apps, but the advantages make up for it.


Kotlin is a rather small, but up-and-coming programming language for Android apps. It is statically typed, which means that the code must be declared with all variables before it is compiled. This is not atypical, in Java, for example, it happens the same way. In general, Kotlin is very much based on Java and after a bit of conversion can even read and interpret Java codes.

Now that begs the legitimate question why not just use Java to program the Android app. Kotlin is based on Java, but develops it further, which makes the programming language particularly friendly for Android apps.

A big point here is that Null Pointer Exeptions. These describe common errors that can occur in Java code. These occur when a variable is incorrectly declared in the code or has no value at all. In Java this often causes problems, since otherwise a flawless code becomes completely unusable.

Kotlin offers a kind of early warning system for this by warning of the error before compilation and a solution is presented. This avoids hours of puzzling around and lost working time.

Furthermore, Kotlin is much shorter and clearer. Certain actions, such as the conversion of different data types, happen automatically here, without having to write additional methods. If you want to program an Android app with this, it will run more efficiently. Kotlin is a very good programming language for Android apps.

Development environments such as Android Studio

In addition to the programming languages ​​for Android apps, you also need the interface of the app itself for their development. Programs such as Android Studio, which is provided by Android itself, help here. With numerous templates and simple operation, the studio helps with programming. While the languages ​​provide the logic, the user interface is built here with XML. This can be done by simple drag and drop or by programming yourself.


There are many ways to program an app. Java is the most common and offers easy entry and platform independence.

C is a bit more difficult to start with, but it makes up for it with faster and more efficient programs.
Kotlin specializes in developing an app. It is not very common, but it is easy to use and compatible with Java.

A programming language for Android apps must be selected individually for each project. App development can always look different and each language has its own advantages and disadvantages.
