Android is the most popular operating system in the world, with over three billion active users spanning over 190 countries. The reason behind Android's popularity is that it is affordable and has the capacity to perform various tasks that an iPhone can do. It is an open-source operating system, and the source code is available to the public. Device manufacturers are able to customize it according to their requirements and use it freely without the need for licenses and royalties. Manufacturers choose Android due to this flexibility, which has resulted in the rapid expansion of the Android ecosystem.
Android app development refers to developing software applications that use the Android operating system. App development focuses on coding, testing, and debugging applications. Android apps are written using languages like Kotlin, Java and C++. Depending on the project’s needs and preferences, developers choose a language for Android app development. Here are the top 5 programming languages used for Android app development.
1. Java
Java is the most sought-after language for Android app development. Many apps in the Google play store are built using Java. Its compatibility with any operating system equipped with a compatible Java Virtual Machine (JVM) speaks about its popularity.
Java is one of the first true cross-platform languages with its write-once, run-anywhere approach. Java’s biggest advantage is its security and stability. The virtual machine provides an additional layer of security that prevents any malicious code from being executed. This layer enhances performance through features like memory management.
2. Kotlin
Kotlin is derived from Java but with significant improvements. The most notable improvement is its conciseness. It is not as verbose as Java and allows developers to implement ideas with fewer lines of code. When a Java code is rewritten in Kotlin, the length of the code reduces by almost 40%. The best thing about Kotlin is its interoperability with Java, as Kotlin code is compiled into bytecode that also runs in the JVM.
Kotlin has both object-oriented and functional constructs. With excellent support for features like higher-order functions, function types, and lambdas, Kotlin is a great choice for developers who are doing or exploring functional programming. It boosts productivity, developer satisfaction and code safety.
3. C++
C++ is one of the most powerful and versatile languages today. It’s used to build everything from cutting-edge 3D games to operating systems. If the program is complex and advanced, chances are developers will build it with C++. However, C++ isn’t a native Android language. To use it, you’ll need to convert the code using the Android Native Development Kit (NDK). This allows your Java or Kotlin code to access the converted C++ code.
C++ is a supplement to Android languages but one of the fastest programming languages ever.
It’s often used to implement performance-critical components, like game engines, real-time audio, and computationally intensive tasks. Unlike Java, C++ is compiled into machine code that runs directly on the device without runtime machines or interpreters. The lack of an intermediary reduces overhead significantly, making it execute faster.
4. Dart
Dart is Google's cross-platform mobile app development tool. One of Dart’s greatest strengths is that it is very easy to learn. Dart uses English-like syntax that’s intuitive to read and understand, similar to modern languages like C# or Javascript. Thus, Dart makes for an easy switch for an expert or a great gateway for the beginner.
One of the most powerful features of Dart is the hot reload. This capability allows developers to edit the code and see changes in real-time. This speeds up development dramatically by eliminating the time-consuming write-compile-test-edit cycle. Dart is very fast for a cross-platform language because Dart code is compiled into native Android code, resulting in good performance and smooth animations.
5. Python
Python is a versatile app development language known for its simplicity and readability. It powers renowned platforms like Netflix, Reddit and Uber. Its cross-platform capabilities ensure smooth operation across various systems and devices. Python’s support for multi-threading enhances concurrent request management and overall performance. Its clean and user-friendly syntax is beginner-friendly, making it a great choice for newcomers to programming.
The robust community support provides a wealth of resources for addressing inquiries during the app development process. Its interpreted nature enables rapid prototyping and testing, appealing to both beginners and experts.
The choice of mobile app development language depends on several factors, such as project requirements, target platforms, and developer expertise. By carefully evaluating the strengths and limitations of each language and considering the specific needs of their projects, developers can make informed decisions that lead to the creation of exceptional mobile app experiences.
