1. How do you explain Android to people with no software development background?

Android is an operating system for Android devices developed by Google. For comparison, it is like iOS for Apple devices or Windows for desktops. Android is Linux-based. It allows developers to create applications for your mobile devices.

2. What are the main features of Android?

Android has plenty of features that make it easier for developers to develop and upgrade applications. These features include:

  • It is open source
  • Flexible and customizable operating system
  • Supports development of a different variety of apps
  • It is less complex compared to iOS
  • Able to support messaging and web browsing services, storage and connectivity, and various types of media

3. What is Android Architecture?

Android Architecture refers to the different types of layers on an Android stack. These are the operating system, middleware, and applications. Each layer provides different services. The layers include Linux Kernel, Libraries, Android Framework, and Android Applications.

4. In Android development, which programming language is used?

For Android application development, the primary programming language used is Java. Although it is possible to develop apps using C or C++, Java is the most used language for Android. Plus, Android’s APIs are designed for Java as well.

5. In Android development, what are File, Class, and Activity?

In Android app development, Files are resources for storing information. Meanwhile, Classes produce executable APKs from files compiled from Java. On the other hand, Activities are not files. Instead, they a class or classes. They are used to load UI elements on view.

6. Define Android frameworks.

Android frameworks are APIs that allow developers to write code. They are a crucial part of Android Architecture.

7. Why is it not advised to change the file name of an application after deployment?

Changing the name of an Android application after deployment may cause some of its functionalities to break down.

8. How can you improve teamwork while developing an app?

Android app development can be very hectic once its starts. As a developer, I will have to coordinate and collaborate with other team members, including non-development staff. 

To avoid misunderstanding, I believe there should be an open communication line throughout the process. Also, it would be conducive for everyone in the team to write their code clearly and in an organized manner. This way, it would be easier for the other members to pick up where the previous member ended their tasks.

9. Have you experienced not being able to meet a deadline? Explain.

It rarely happens, but sometimes, there are projects that I could not meet certain deadlines. Most of it occurs when unforeseen problems come up. That’s why I strongly believe that proper planning and documentation are very important.

My previous team was in charge of developing an app that monitors users’ health. I am very interested in wearable health applications. And being a part of the team was a learning experience.
