Android development provides advantages to organizations that release
new apps, such as lower development costs and greater promotional reach
and potential. Because of this, more doors open for Android developers.
Android should be your OS of choice because no recurring charges are
associated with using the Android Software Development Kit (SDK).
Despite including the price of creating audio, assets, and graphics, as well
as the cost of coding, this app development method is much more cost-
effective than designing an app for a separate operating system. Using
Android, developers can create dynamic apps on every device with little
capital outlay and maximum return on investment.
Once an Android app has been designed and tested, the approval and
deployment process on Google Play Store often takes only a day. The
entire process is simplified, from creating an app to releasing it.

5. Android Developer Jobs: Essential Questions
Do you have the necessary expertise? Excellent, because you can expect to be
bombarded with questions at any tech job interview. For an Android developer
position, you can anticipate questions like these:
What are the commonly used Programming Languages for creating native Android
apps?
For this relatively easy Android developer interview question, you should be
prepared with a list of commonly used programming languages, including Java,
Kotlin, C#, Python, and Groovy. Include a few Integrated Development
Environments (IDEs) like Eclipse, NetBeans, IntelliJ, and Android Studio for
bonus points.

6. Moreover, The interviewer may alter their attention to questions about specific
technologies depending on the nature of the role and the candidate’s prior
experience. The interviewer may not even ask about Java if Kotlin is more
important for the job. However, even if candidates have extensive prior
knowledge of Java, they may still be asked questions in this area.
What are Android architecture and components?
Android architecture is a software system designed to meet the requirements
of mobile devices. The Android software stack consists of a Linux Kernel, a
collection of C/C++ libraries exposed via an application framework’s services, a
runtime, and an application.
The following are primary Android architecture components:
Applications
Android Framework
Android Runtime
Platform Libraries
Linux Kernel
What are the benefits and drawbacks of using Kotlin?
Java is well-established and pervasive, but Kotlin’s popularity continues to rise. If
prompted, use this question to demonstrate your knowledge and skills with
Kotlin by describing how it can eliminate NullPointerException from code, has
cross-platform app development capabilities, and typically has improved
readability.
Moreover, after establishing project experience, the interviewer will tailor
technical questions to the candidate. If the person has never utilized RxJava

7. operators or Kotlin-Java interoperability, discussing them is unnecessary.
How are permissions managed on Android?
Android permissions govern how users gain access to sensitive application
data. As an Android developer, you are responsible for restricting data access
while preserving functionality. List some recommended practices for Android
permissions, such as configuring default handlers and choosing third-party
SDKs with similarly restricted permissions.
What Is the Google Android SDK?
Developers require the Google Android SDK in order to create applications for
Android-enabled devices. It includes a graphical interface that emulates an
Android-powered handheld environment, enabling developers to test and debug
their code.
Describe the Android Framework.
Android Framework is a crucial component of Android Architecture. Here you
will find all of the classes and methods developers require to create Android
applications.
What does ANR mean?
In response to this intermediate interview question, you should describe
Application is Not Responding (ANR) and how you might prevent it from
happening. A long calculation taking place on the main thread or a synchronous
binder call with another process taking a long time to return are two frequent
patterns used for diagnosing ANRs and should be mentioned alongside the
trigger circumstances (a response to an input, a broadcast receiver does not
execute in a suitable period).

8. Describe Activities
Activities are a type of user interface window. In the same way, you create
windows to display output or request input in dialogue boxes, activities serve
the same purpose, albeit sometimes in the form of a user interface.
Explain flavors in Android
The interviewer wants to know if you can distinguish between product flavors
and build categories, as they frequently need clarification. Also, emphasize that
developer customization of apps across multiple codebases is time-consuming
and prone to error, so product flavors are preferable because you can create
app variants using a single code base. Mention these particulars in addition to
describing Gradle, as it generates distinct build type variants.
What are the Intents?
Within an Android-enabled device, Intents displays notification messages to the
user. It can be utilized to notify the user of a specific circumstance. Users can
be pushed to comply with intents.
You can impress a hiring manager or other important contact by mastering the
answers to these questions.
Responsibilities of Android Developers
In the first place, let’s address the topic of responsibility. As an Android
software developer, you can expect to handle several primary responsibilities;
however, the specifics Android developer job description may change from one
organization to the next.
