Weather App - Android Technical Task

👉 Video Demo for this task on youtube 👈

Weather application

• Created android screen that has search bar on top.
• Detected current location of the customer.
• Using https://openweathermap.org/api. Current weather data web service to provide all the necessary data.
• All permissions is properly handled .
• There are no restrictions on use of external libraries.

Project Dependency Graph

• App module depend on core + feature search current weather + library location tracker : contains app start point it may be a splash screen.
• Core module depend on nothing : contains all sharable data among different modules.
• Feature Search current weather Module depend on core + library location tracker : contain search weather feature related ui and other staffs.
• Library location tracker depend on core : contain code of getting current user location.

Use domain specific langauge

• Make gradle scripts easy
• Support Kotlin for better dependencies management by Using Domain-Specific Languages.
• Support autocomplete

Modular architecture

• Speeds up builds
• Enable on demand delivery
• Simplify development
• Reuse modules across apps
• Experiment with new technologies
• Scale development teams
• Enables refactoring
• Simplifies test automation

MVVM Inside each module

• each developer inside android team has a free to select suitable architecture for his module.

Dependency injection with Hilt

• Hilt is a dependency injection library for Android that reduces the boilerplate of doing manual dependency injection in our project.

Enable AppCenter Pipelines

• Support CI so i can check different stages like build and run unit test before merge any branch to master branch.

Detekt

• to make code style analysis and be sure follow best practice for writing kotlin code.

Firebase crashlytics

• to rack bugs even though app moved to production

To avoid 64k functions problem and get smaller apk

• Enables code shrinking, obfuscation, and optimization for only
• Enables resource shrinking, which is performed by the

Data binding

• The Data Binding Library automatically generates the classes required to bind the views in the layout with your data objects.

leakCanary

• to detect memory leak through debugging process that will improve app performance as well.

Truth For unit test its recommended from google

• write unit test for Search Validator Class

Reactive programming (Coroutines)

Coroutines is Google recommended solution for asynchronous programming on Android. Noteworthy features include the following:

• Lightweight: You can run many coroutines on a single thread due to support for suspension, which doesn't block the thread where the coroutine is running. Suspending saves memory over blocking while supporting many concurrent operations.
• Fewer memory leaks: Use structured concurrency to run operations within a scope.
• Built-in cancellation support: Cancellation is propagated automatically through the running coroutine hierarchy.
• Jetpack integration: Many Jetpack libraries include extensions that provide full coroutines support. Some libraries also provide their own coroutine scope that you can use for structured concurrency.

PermissionsDispatcher

PermissionsDispatcher provides a simple annotation-based API to handle runtime permissions.

• Fully Kotlin/Java support
• Special permissions support
• 100% reflection-free
