I'm safe, readable, I'm Kotlin DSL
Nowadays, readability and building things dynamically aren't optional anymore.
In this session, we will walk through how Kotlin DSL makes the code more readable, easy to understand and looks like normally spoken languages.
Besides that, we will deeply understand how can we build a feature using Kotlin DSL, as a real live example we will deeply discuss how navigation graphs could be built dynamically.
How easy is drag-and-drop in compose?
Drag-and-drop seems complex for Android Developers; however, in Compose, it's easy to understand and implement with the lowest complexity ever.
In this session, we will create an agile/kanban board where we will discuss how the drag and drop feature works from a real-life example
Passwordless App with Passkey
Most of the apps include a login feature, where the user should enter his username and password to be able to sign in.
However, passwords are easily forgotten and could be phished by hackers, and some apps force users to provide a strong password, which would be easily forgotten in the future.
Using Biometric login provides a more secure and easier way to sign in; however, it is still limited to the device itself, so if I'm using a platform that provides a mobile application and website, I can be signed in with the mobile device, but I can't be signed in with biometric on the website.
Passkey provides a seamless sign-in experience using biometric fingerprint or face recognition across all platforms, including mobile and websites.
With passkey, the user will have all sign-in options in one place, e.g., normal username and password, federated sign-in (such as sing-in with Google), and biometric. Which makes it easier and clearer for the user.
Passkey is new in Android 14 and has backward compatibility with Android 9, which will make it widely used in the future.
During the talk we would have a live demo application on Passkeys, to make it easy for the audience
Super fast Jetpack Compose with Relay
No doubt that Jetpack Compose make Android Developers life easier, However, Relay make it more and more.
Relay is the integration between Figma and Android UI to auto-generate the Composable function as designed in Figma. Moreover, any change on Figma could be reflected to the Composable functions automatically.
This official integration makes 99.99% matching between the UX/UI design and the Android UI Implementation.
