Android Jetpack: Room, Navigation and Data Binding

Create a new Android Studio project with an empty activity named notes, enable Android X, and set the minimum API level; explore project structure, then run or debug the app.

Configure Android Studio to import and synchronize the required Room and Navigation libraries, set version variables, apply plugins, and fix mistakes to ensure the project builds and runs.

Navigate apps with the Jetpack navigation component, managing back stack, destinations, actions, and deep links via the navigation graph, nav host fragment, and nav controller, with safe args.

Preview a two-screen notes app built with Android Jetpack navigation, featuring an empty notes list and a button to navigate between screens, with fragments, layouts, and a navigation xml resource.

Configure navigation with jetpack navigation to switch between two fragments, the home and add note fragments, via a navigation graph and actions like note and save notes.

Designs the home and add-note layouts using a recycler view, card views, and a floating action button to navigate to the add note fragment, with editable text fields.

Explore navigation between home and add note fragments using generated actions, nav controller, and fragment directions; implement button clicks to navigate and leverage navigation to manage back stack and state.

Explore how Room provides a persistence library with an abstraction layer, entities and daos, compile-time checked queries, and support for migrations, live data, flow, and tests.

Build a Room library-based database by creating a new note, reading notes into a fragment using a RecyclerView, updating notes, and deleting with a confirmation dialog.

Define a room entity note with auto generated id and primary key, implement a dao with insert, get all, update, delete, and build a singleton room database to manage notes.

Implement a note saving flow using Room in a fragment, handle input validation, run database writes on a coroutine, and navigate back after a successful save.

Display notes from the Room database in a recycler view, binding each note's title and body via a notes adapter.

Update notes in the Room database by passing a Note object between fragments, loading existing data into the add note screen, and saving changes through navigation with Parcelable arguments.

Create a top-right delete icon and menu, display a confirmation dialog, and upon confirmation delete the note via the DAO and navigate back to the home fragment.

Binds a data object to UI layouts using the data binding library, reducing boilerplate, binding events and attributes directly, and enabling custom attributes with binding adapters and expressions.

Learn to implement data binding in Android Jetpack by setting up the binding library, updating layouts, binding notes to views, and binding note clicks.

Enable data binding in the app module, declare a data note variable in a layout, and bind the note title and body to the ui.

Bind method calls in Android by using a click listener interface, wire on note clicked in the adapter, and navigate to the editor with the selected note.
