• Kotlin: 

Kotlin is one of the top programming languages for developing Android apps. It is cross-platform, general purpose, statically typed, language with type inference, and the best programming language. It is also known as the family language for building applications for Android. Android Studio also supports it. It is suitable for Android developers because it provides touchpoints for developing seamless applications. This is why Android developers always prefer Kotlin for custom Android app development. 

The Kotlin development language comes with the code syntax. Moreover, you can use it in native code or JavaScript. It works via Java Virtual Machine and here are the best features of this popular programming language. 

• Null Safety
• Operating Overloading 
• Smart Cast
• Object Oriented Programming
• Operator Overloading 
• Interference type 

•  Java

Java is a high-level, class-based, object-oriented programming language. Its design minimizes implementation dependencies. For its robustness and a blend of interpreted and compiled code, Java is a top choice for server-side development due to its advanced safety and security features. It also supports complex programming constructs. It includes constructors, checked exceptions, and null pointer management. 

The language is an ideal choice across platforms because it does not depend on implementation dependencies. You can also call it the crowning language for programmers. Here are its features that you need to know about: 

• Multithreaded
• Architectural neutral 
• Simple and portable
• Platform independent
• Distributed system

• C/C++

C++ is known for its high level, and multi-paradigm, C/C++ is best for Android app development. Google offers a Native Development Kit also known as NDK. It is a toolset that easily integrates with the SDK and deploys native languages such as C/C++ for Android application building. C++ is enabled to build a complete program and NDK allows you to develop a native library that is useful in Java Programs. 

In most of the cases, NDK is crucial. So, rather than crafting a code that works on JVM using NDK, you can write a code that works natively on the device.  C/C++ libraries use this approach to develop Android applications. Further, C/C++ programs are easy to write and easy to use. These are the trendy Android app development programming languages that are useful across industries, like banking, gaming, and more. Here are the USPs linked with C++/C: 

• Abstraction
• Memory management
• Structured programming
• Compiler based
• Case sensitive

• C#

C# is one of the highest-level languages in the .Net environment. The developers who know well Microsoft’s C and C++, C# offers a more work-oriented type of these two languages. However, C# is not a typical Android app programming language. It is one of the best frameworks that empowers to development of native, cross-platform frameworks. It could be MAUI and Xamarain. These are the frameworks that empower developers to write  C# code and compile it to native Android apps. It further provides access to the Native APIs and Android SDK. 

C# is one of the best Android app development programming languages these days. It has remarkable performance and is best for the development of resource-intensive applications. In addition to that C# programs are very easy to craft and understandable. The language is easy to use because Microsoft needs its tools for multiple independent stages. It allows developers to build an Android app without any purchase. Here are some features that are as follows: 

• Rich library
• Typesafe
• Scalable and updateable
• Component oriented
• Interoperability

• Python

It is one of the best languages when it comes to developing Android apps. Further, Python is a general-purpose, high-level programming language these days. It offers a design philosophy that deals with code readability. In those days it was impossible to develop Android applications with the help of Python language. However, today we have multiple third-party tools that are available to use Python programs with Android mobile devices. Its features such as dynamic binding and typing make it the best programming language for Android application development. 

It is effortless for crafting codes, and faster the process of app development as compared to the other programming languages. Android app development costs with the help of Python become minimal and even for maintenance. Python is useful to build large commercial apps. Here are some features that you need to know about: 

• GUI programming support
• High-level language
• Free and open-source
• Dynamic memory
• Large standard library
