Frequently Asked Android Application Development Course Interview Questions

1: What is Android?

Ans: Android is an open-source mobile operating system developed by Google. It is based on the Linux kernel and is designed primarily for touchscreen devices such as smartphones and tablets.

2: Explain the Android application components.

Ans:Android application components include activities, services, broadcast receivers, and content providers. These components work together to form the basis of Android applications.

3: What is the difference between Java and Kotlin in Android development?

Ans: Java and Kotlin are both programming languages used for Android development. Kotlin is more concise, expressive, and null-safe compared to Java. It is fully interoperable with Java, meaning you can use Kotlin and Java code in the same project.

4:Explain the concept of an Activity in Android.

Ans: An Activity represents a single screen with a user interface. It is the basic building block of Android UI and can contain layout elements, such as buttons, text fields, etc. Activities are used to interact with the user and handle user input.

5: What is a Layout in Android?

Ans: A layout defines the structure for a user interface in an Android application. It organizes the UI elements, such as buttons, text fields, and images, on the screen.

6:Explain the difference between match_parent and wrap_content in layout parameters.

Ans:match_parent (or fill_parent) specifies that the view should take as much space as its parent view allows. wrap_content specifies that the view should be only as big as needed to fit its content.

7: What is SQLite in Android?

Ans: SQLite is a lightweight, embedded relational database management system. It is used as the default database engine in Android devices. Android provides built-in support for SQLite databases.

8:Explain the difference between Shared Preferences and SQLite databases.

Ans: Shared Preferences is used for storing small amounts of data in key-value pairs, mainly for user settings. SQLite databases are used for storing structured data in a relational database format. Shared Preferences are simpler and ideal for small data, while SQLite databases are suitable for larger datasets and complex data relationships.

9: What is AsyncTask in Android?

Ans:AsyncTask is a class in Android used to perform background operations and update the UI thread. It allows you to run tasks asynchronously without blocking the UI thread. However, it is deprecated in newer versions of Android, and developers are encouraged to use more modern approaches like Kotlin Coroutines or RxJava.

10: Explain the purpose of the AndroidManifest.xml file.

Ans: AndroidManifest.xml is a configuration file that contains essential information about the Android application. It includes details such as the application's activities, services, permissions, hardware requirements, and other crucial settings required by the Android system to run the app.

11: What version control systems have you used for Android development?

Ans: Mention the version control systems you are familiar with, such as Git, SVN, or Mercurial. Explain your experience with the system you mention.
