ANDROID APP DEVELOPMENT COMPANY

New open source programming language that is used by Google to replace Java for building Android apps. It has a clear syntax, it can be compiled to JavaScript or JVM bytecode easily, and due to integration with all Java frameworks and libraries, app development process goes faster and gives developers more tools to build native Android apps.

This Backend-as-a-Service platform frees developers from such backend work as managing servers and writing APIs and lets them focus on building the top-notch user experience. Being almost an all-in-one backend solution, Firebase helps to speed up the Android native app development.

It is a lightweight database that geared toward getting rid of server-client architecture and storing all the app data directly on a mobile device. This DB is based on files, so provides the wide range of capabilities for developers. Since SQLite doesn’t send requests to server, it is much more powerful and faster.

Realm is a popular mobile database for every app development platform. It’s incredibly rapid (much more rapid than SQLite), cross-platform, thread-safe, and has an easy-to-use API. The developers call it a contemporary and reliable substitute for the native Apple’s databases.

This is Android open-source unit test framework that allows QA specialists to launch tests for Android apps via local JVM. This Android app test type is similar to black box testing, and the test can become more efficient for refactoring, and the behavior of the app can be tested as well. The framework makes the testing process faster.

RxJava is a specific implementation of reactive programming for Java and Android, an open source library that has Observer patterns and iterator patterns that help build good software with front-end and back-end parts. It offers developers intuitiveness, extensions, quick reacting to any changes.

JUnit is an open-source unit testing framework in the Java language. It provides an incredible opportunity to write code and test it simultaneously! This framework is able to create test suites step by step to thoroughly trace all possible side effects. Thus, it is very powerful and its graphical interface make the whole testing process simpler.

It is a mocking framework for effective unit testing of Java applications. This tool facilitates creating mock objects and allows programmers to verify the behavior of the system under test without establishing expectations beforehand. As a result, you will get a simpler test code that is much easier to read and edit.

Espresso is an automation tool created by Google. Being used for writing concise and reliable UI tests, this framework has many advantages to both developers and QA engineers, so dramatically accelerates the development process. It is easy to use within popular IDEs and provides useful testing annotations and assertions.
