Every Android
Developer Should
Know

2. No matter how you have learned to build
Android apps, to take your Android Skills to
the next level, you must learn the seven
crucial things provided here.

3. Let’s explore the
7 crucial things

4. ❑ Android architecture plan should be followed
consistently, as it gives knowledge of how the different
application components should be organized and tied
together.
❑ It even provides guidelines during the development
process and forces some sacrifices that help in the
development of well-written applications.
1. Android Application Architecture

5. ❑ Knowledge of Java and Kotlin programming languages
is a must as they are game-changers for Android
Developers.
❑ Kotlin integrates seamlessly with Java code, so you can
easily write codes with existing Java code.
❑ Java on the other hand is used in an integrated
development environment for Android application
development.
2. Knowledge of Java & Kotlin

6. ❑ Android SDK, a collection of libraries and tools, gives
you access to mobile device functions like the camera
and accelerometer.
❑ The SDK represents Android’s toolkit for a specific
version and technology of its operating system.
❑ Every time Google releases a new version of Android, a
corresponding SDK is also released.
3. Android SDK

7. ❑ Android Studio makes it seamless for Android
application development on any interface.
❑ Android Studio is built on JetBrains’ Intellij IDEA
software and is designed especially for Android
development.
❑ You should know the working of Android Studio as it
supports all programming languages of PyCharm,
Kotlin, Python as well as Intellij.
4. Android Studio

8. ❑ The android application undergoes various states and
that is called the Android Activity Life Cycle.
❑ Activity is one of the most important components of
Android where you put the UI of your application.
❑ Developers new to Android applications should know
what an Activity in Android is, and what is the lifecycle
of an Activity.
5. Android Activity Lifecycle

9. ❑ Constraint layout gives you adaptable and flexible
ways to create views for your apps. And also many
ways to place objects.
❑ Using constraint layout you can create large, complex,
dynamic, and responsive views in a flat hierarchy.
❑ It flattens the view hierarchy and gives better
performance, making it easier for developers to put
together the UI.
6. Constraint Layout

10. ❑ Architecture patterns are applied to structure the
project’s code and give it a modular design. Following
are the popular Android architectures used by
developers.
❑ MVC (Model – View – Controller) pattern is the oldest
app architecture.
❑ MVP (Model – View – Presenter) pattern is the second
iteration of the Android app architecture.
❑ MVVP (Model – View – ViewModel) pattern is the third
iteration of Android architecture.
7. Android Architecture Patterns

11. To become a full-fledged Android developer not only you
must know the above-mentioned languages and skills, but
along with that, will have to brush up with additional back-
end technology skills such as .Net, Rails, Django, NodeJS, etc.
Having knowledge of these skills will give you a full-rounded
view of how the Android application works and interplays
with middleware or backend.
