3. The best practices can help answer the question- how to make an Android app. This
includes device fragmentation, user experience and maintenance of the code.
Android is a fragmented operating system with a plethora of devices and form factors. It is
important for mobile app developers to consider these aspects before creating solutions.
In this guide, we will look at the best practices. We will also take you through the top tips
that can help you build an engaging and interactive Android app solution.
INTRODUCTION
Getting up to speed with Android App Development requires mastering the fundamentals.
From designing the UI to coding the logic, carving out a successful app requires knowledge
and experience in many areas. Learning the best practices for Android App Development is
essential for any aspiring developer who wants to create apps that stand out from the rest.
With a few tips and tricks, you can quickly become an expert at developing for this popular
platform.

4. #1. Determine the Code Quality
Code development is nothing short of
creativity. There are several ways in which
a developer can create the same code. It
depends on their style of writing, their way
of expressing the language and of course
coding habits.
However, code quality is the most crucial
part of your app development best
practice. Considering you will be creating a
code for multiple devices and form factors,
you need to ensure the code is uniform.

5. #2. Plan for fragmented devices
Device fragmentation is core to Android.
There is no single type of device or form
factor that you can find for Android
devices. In fact, each device manufacturer
has a different type of screen, capabilities
and component usage under the Android
banner.
If you develop an app screen by focusing
on a particular screen size, you might be
unfair toward other screen types.

6. #3. Focus on usability
The app’s usability is key to garnering more
conversions. If your app is not usable or
cannot be accessed by different users, they
may churn out. This might impact your
overall popularity and app store ratings.
The app usability depends on factors such
as usefulness, credibility, and value
addition. You should make the app
desirable and accessible for the users.

7. #4. Implement agility for better processes
Agile methodology is a great way to
introduce changes. It can accelerate
development and deliver your app to the
market with quality and performance.
The continuous collaboration between the
development, operations and client teams
can help accelerate the development. It will
also help divide the entire development
into smaller portions that are easy to
handle and test.

8. #5. Build Secure Applications
Focus on security is an important part of
Android app development. A vulnerable
app will see a downfall at the app store. It
will impact your ratings and the conversion
rate. This can also help you differentiate
your application from the competition.
Session management is an important
security consideration. You should
implement risk mitigation strategies and
include encryption for better security
management.

9. #6. Implement Unit Tests
It is important to know if each unit within
the app functions as expected. This should
be your testing priority. You will know the
debugging plan, can identify the errors/
issues and find the mitigations with these
unit tests.
It is important to run these unit tests on
JVM as you will get the perfect results.
Testing on the emulator or physical device
will cause debugging issues.

10. #7. Avoid Floating Point
One of the critical factors for an engaging
application is performance. If your app
doesn’t match the required performance
or speed, your users may churn.
You should ideally avoid using Floating
Point during Android development. This
simply means avoiding using floating-point
number values. This can cause your app to
slow down by 2x. It can eventually impact
user conversion.

11. #8. Address Memory Leak Issues
This is one of the most persistent issues in
Android app development. This can
significantly impact your user experience.
Memory leaks can lead to increased crashes
and friction, which would reduce
engagement. Eventually, it would lead to
increased churn.
LeakCanary is an excellent tool that can
handle memory leaks. It will detect if there
are any issues in the memory and resolve
them in the early stages.

12. #9. Avoid Third Party Libraries
This cannot be entirely avoided when
developing an Android application. However,
extensive dependency on third-party
libraries can cause troubles within the
application. You may notice data leaks, and
even frictions getting the queries.
It is important to select the right libraries for
Android development. Conduct a thorough
privacy check before you integrate with the
library.

13. #10. Implement Android Debug Database
Database debugging is an important part
of Android application quality assessment.
You should check the database for
real-time communication, query responses
and other aspects.
The Android debug database feature gives
you a complete view of the database. It will
give you a glimpse into the sharing
preferences, the settings and other aspects
directly via the browser.
