Displays current weather conditions and a 14-day forecast for the device's location. It also allows to search the weather by a city name. The app integrates coroutines with Retrofit to fetch weather information and binds all UI components in the XML layout to data sources using a DataBinding rather than programmatically. The UI calls are done in Binding Adapters reducing boilerplate code in the fragment. All is done following Model-View-ViewModel (MVVM) architecture for the presentation layer. Using repository the web services is abstracted from the rest of the app. The weather is exposed from the view model via LiveData and bound to a views so they're refreshed automatically when condition changes. The button's onClick attribute and the TextWatcher attached to the EditText are bound to the view model via a lambda expression.

Displays up to date weather info for the current device's location. The widget is updated periodically with new data through a WorkManager. When the widget is added to the screen, the WorkManager schedules repeated background work to request location updates and fetch weather data from the API performing suspending work. When the widget is removed the background work is terminated. In addition to the FINE location permission, the app has support for Android 10 and 11 by adding logic to access location in the background (android.permission.ACCESS_BACKGROUND_LOCATION).

• App offers a full edge-to-edge screen experience (draws behind the transparent navigation and status bars) and uses insets to move controls away from gesture area.
• The app displays Snackbar explaining importance of the location permission with an action, that allows the user to navigate to the settings.
• Scrolling list of forecasts is displayed in the RecyclerView widget.
• Styled button behaves intuitively changing their appearance when they are pressed.
• Spinner is displayed when the data is loaded.

• Retrofit to make REST requests to the web service integrated with Coroutine to run operations in the background without creating multiple callbacks.
  
• Moshi to handle the deserialization of the returned JSON to Kotlin data objects.
  
• Android Architecture Components (ViewModel, LiveData, Data Binding, WorkManager).
  
• The app accesses the set of supported location services through classes in the com.google.android.gms.location package.

• Icons from Flaticon.com (byFreepik, Swifticons, Good Ware, Vitaliy Gorbachev, Those Icon, Hirschwolf Lineal, Iconixar, Eucalyp, Pixel Perfect).

• using the OpenWeatherMapAPI for constructing RESTful.
