Debugging
Techniques

2. Introduction
to Android
Debugging
Debugging is the process of identifying and removing
errors or defects from software applications.
In Android app development, debugging is crucial to
ensure the app's functionality, performance, and user
experience.
Common bugs in Android apps include logic errors,
null pointer exceptions, memory leaks, and UI issues.
Android provides various debugging tools and
techniques, such as Logcat, Android Studio Debugger,
and profiling tools.
Effective debugging leads to stable, reliable, and high-
performing Android apps.

3. Android Studio Debugger
Android Studio, the official IDE for Android development, includes an integrated debugger.
Developers can set breakpoints to pause the app's execution at specific lines of code.
Step through the code line by line using step into, step over, and step out commands.
Inspect variable values and evaluate expressions at runtime.
Debug techniques like conditional breakpoints and watchpoints aid in advanced debugging
scenarios.

4. Google Acquires
Android
In 2005, tech giant Google recognized Android's potential and
acquired the company. This move marked a turning point,
providing financial backing and Google's engineering expertise.
The goal shifted towards creating a powerful open-source
mobile platform to rival existing competitors.
• Google saw Android's potential to create a wider mobile
ecosystem
• Acquisition fueled Android's development with increased
resources
• Open-source model was key to Google's strategy
• Aimed to compete with Symbian, Blackberry OS, and emerging
iOS

5. What is
Android

6. Why is Android so
Popular?
• Open-Source: Freely available for manufacturers to
use and modify
• Customizability: Users and manufacturers can tailor
the experience
• Massive App Store: Google Play Store offers millions
of apps.
• Frequent Updates: Google regularly adds new
features and security improvements
Android's tremendous popularity stems from several
factors. Being open-source means lower costs for
device makers, leading to a wider price range for
consumers. Android devices offer a high level of
personalization in appearance and functionality.
Additionally, the Google Play Store is the go-to source
for a vast library of apps, and Google consistently
enhances Android with updates and security patches.

7. Dynamic Color Theming
• Android adapts its entire color palette based on
your wallpaper.
• System UI, icons, quick settings, and even some
apps change to match your aesthetic.
• Creates a cohesive visual experience across your
device.
• Easier on the eyes due to harmonious color choices.
• Your phone feels uniquely yours.
Android's Dynamic Color Theming is a visual
revolution. Your wallpaper becomes the source of
inspiration for the entire look and feel of your phone.
Menus, buttons, and even compatible apps are
infused with your chosen color scheme, establishing a
highly personalized and elegant look.

8. Redesigned Widgets
• Widgets are now more interactive and informative
than ever.
• Many widgets come in multiple sizes, allowing you
to customize your home screen layout.
• Access quick controls and glance at important
information without opening apps.
• Widgets provide both utility and visual appeal to
your phone.
Widgets are no longer mere static icons. Recent
Android versions empower you with resizable,
interactive widgets. Check the latest news headlines,
control music playback, manage your to-do lists, or
monitor the weather – all from your home screen.

9. Enhanced Privacy Dashboard
• Centralized hub showing what permissions apps accessed in
the last 24 hours.
• Timeline view for precise tracking of camera, microphone,
and location usage.
• Easily revoke permissions from any app directly inside the
dashboard.
• Approximate location setting to limit precise location
tracking.
• Indicators for camera and microphone usage in the status bar.
Taking a user-centric approach, Android's Privacy Dashboard
grants you unprecedented control over your data. Know exactly
which apps are using sensitive permissions, and when. Quickly
cut off access if desired. New indicators clearly signal when
your camera or microphone is active.

10. Focus Mode
• Pause distracting apps with a simple tap.
• Create custom Focus Modes for different
scenarios (work, study, etc.).
• Schedule Focus Modes to automatically
activate at specific times.
• Silences notifications and visual interruptions.
• Stay on track and avoid getting sidetracked by
your phone.
Sometimes it's vital to block out the digital
noise. Focus Mode lets you temporarily disable
apps you find distracting. Tailor different modes
for work, personal time, or whatever helps you
stay on task. Schedule them, activate them
instantly, and regain control of your attention
span.

11. Seamless Media Switching
• Redesigned media controls with a dedicated
output switcher.
• Easily switch audio between phone, headphones,
speakers, and other compatible devices.
• Works with apps like Spotify and YouTube Music.
• Enjoy continuous listening as you move through
different environments.
Android delivers a seamless audio experience.
Switching between your headphones, your smart
speaker, or your car's system is now as simple as a
few taps. Your music or podcast follows you
effortlessly, without missing a beat.

12. Improved Copy and Paste
• Recent clipboard history provides access to multiple copied items.
• Automatically suggests edits when you copy text (like adding area code to a
phone number).
• Inline image editor to crop and annotate screenshots before sharing.
• Copy something on your phone and paste it seamlessly on your Android tablet
(or vice versa).
Copy and paste gets remarkably convenient. You no longer have to keep re-
copying things – find recently copied items easily. Android smartly suggests
contextual edits to save you time. Edit screenshots instantly, and even enjoy
cross-device copy-and-paste for supported devices.

13. Nearby Share
• Share files, photos, links, and more with
nearby Android devices wirelessly.
• Works just like Apple's AirDrop.
• Faster and more secure than Bluetooth.
• No internet connection needed.
• Send content to friends, family, and your
own devices effortlessly.
With Nearby Share, Android adopts a
streamlined method for close-range file
sharing. Forget about fumbling with
Bluetooth or relying on cloud uploads.
Select 'Nearby Share,' tap on a visible
device, and transfer items at lightning
speed.

14. Expanded Emoji
Toolkit
• Android keeps adding new emoji with
each major release.
• Wide range of skin tones and diversity
representations.
• Fun and expressive new characters,
objects, and symbols.
• Keeps your chats and texts fresh and
engaging.
Sometimes, only an emoji will do! Android
consistently expands its collection of emoji,
allowing you to react and communicate
with nuance. Expect even more choices for
representing yourself, your emotions, and
the world around you.

15. Smart Battery
Management
• Adaptive Battery learns your app usage
patterns to reduce power drain from less-used
apps.
• Optimized charging extends battery lifespan by
adapting to your overnight charging habits.
• Background power restrictions extend standby
time.
• Get more out of each charge cycle.
Android works behind the scenes to deliver
longer battery life. Adaptive Battery analyzes how
you use your phone and prioritizes battery
resources for your most important apps.
Optimized charging protects your overall battery
health for long-term performance.

16. App Permissions "While Using"
• Many permissions can now be granted only "while using the app."
• Apps don't get background access to location, camera, or microphone
without your knowledge.
• Automatic revocation of unused permissions.
• Enhanced privacy and peace of mind.
Android gives you even finer control over what apps are allowed to do.
Grant access to things like your location only while you're actively using
an app, and not lurking in the background. If you don't use an app for a
while, it loses permissions automatically, reducing security risks.

17. Conclusion
Effective debugging is crucial throughout the app
development lifecycle to ensure quality,
performance, and user satisfaction.
Follow best practices, such as writing testable code,
profiling early, adhering to guidelines, and
collaborating with team members.
Continuous learning and staying updated with the
latest tools and techniques are essential for
successful Android debugging.
Explore additional resources, such as official Android
documentation, developer forums, and online
courses, for further learning.
