Android Application Development

Android is a mobile multitasking operating system used in smartphones, tablets, readers, consoles, TVs, and even domestic robots. The OS was developed by Android Inc. basing on Linux and was later purchased and popularised by Google. The appearance of Android OS in 2008 made a splash, and it immediately became a leader in the market of smart devices. Thanks to this operating system, modern smartphones and tablets can be considered pocket mini-computers.

Android is a flexible and friendly OS with less than one hour enough for an initial acquaintance. Any user can easily configure OS settings as there is a large number of available relevant applications. You can change anything beyond recognition: if you don’t like the appearance, icons, or a ringtone, just go to Google Play, download a relevant application, and quickly configure everything to your liking.

Programming languages for Android application development

Creating an Android application means developing a complicated multifunctional product based on the Linux kernel. Given the sustainable market growth, Android app development is very much in demand now as more than half of all gadgets use this particular OS. Various services, editors, games, and messengers are developed for Android. With such a variety, there are plenty of programming languages available for Android app development.


Java is the primary programming language for Android app development. It is also called the official language of Android as the OS documentation and courses are based on this language. Many developers find Java very convenient for creating mobile apps. The disadvantage of Java is its complexity as this language was designed 24 years ago and it has never been a simple one. Therefore programming in Java requires time and a lot of experience. However, without Java knowledge, one cannot succeed in Android app development. When developing in Java for Android, manifest XML files are used in addition to the code with classes.


Kotlin is one of the youngest languages developed since 2011. It was officially released only in 2016, however, the language has already gained popularity. Kotlin allows you to comfortably create full-featured native applications. Google itself positions it as the second official Android development language. When using Kotlin, possibly due to the IntelliJ IDEA native environment, developers do not experience any problems. It is also highly compatible with Java, it does not reduce performance nor increase file sizes.


C# is an object-oriented application-level language developed by Microsoft engineers in 2000. Though it was created for their own .NET Framework platform, it perfectly suits Android mobile app development. This programming language comprises many useful Java features while eliminating most of the shortcomings.


Google provided developers with two environments: SDK for Java code and NDK for native code in C and C ++. Of course, it is impossible to develop a full-fledged mobile product using only these two languages. But you can write a library with the help of C/C++ that will be further connected to the application base using Java.


Though Python is not used for the full development of Android applications, it is also adapted for some operations. There are plenty of tools to convert Python code into a required state. A variety of libraries support building optimised interfaces in accordance with Material Design recommendations.

Development environment

Android Studio is the most popular and desired development environment for Android. This integrated environment is based on IntelliJ IDEA software. Android Studio has the following features and advantages:

  • advanced layout editor;
  • automatic application building using Gradle;
  • static source code analyser;
  • code redesigning;
  • integrated ProGuard tool;
  • application signing utility;
  • Android basic component and layout templates;
  • Google Cloud Platform suite support.

Adding an application to Google Play

To publish your application in Google Play, do the following:

  1. Create a special developer account in the Google Play Console required to publish apps.
  2. Issue a privacy policy document stating responsibility for the product and its contents and obligation to ensure user confidentiality and user data security.
  3. Prepare marketing materials.
  4. Provide the build with a digital signature certificate required to identify the developer on Google Play, so that only the creator could update or modify versions.
  5. Customise receiving payments within the application.
  6. Send the complete build to Google Play.

Android app development cost

Our qualified team competently approaches the development of any complexity and performs tasks without delay. We will create a unique business model, a convenient and friendly user interface, and will also help with placement in Android stores and marketing promotion.

Creating a mobile application consists of the following stages:

  1. Writing technical specifications (if you don’t have one) — from 18 hours.
  2. Business analysis and specification — from 20 hours.
  3. UI and UX design — about 35 hours.
  4. Back-end development — more than 40 hours, depending on the required functionality.
  5. Front-end development — more than 30 hours.
  6. Testing — about 20 hours, depending on the functionality.

Based on these data, the approximate cost of the MVP app for Android starts at $20,000 and then depends on the level of complexity. Please note that after the development is completed, the application must be supported, and such service is paid separately.
