Android Jetpack- Composable functions




Jetpack Compose is built around composable functions. These functions
let you define your app's UI programmatically by describing how it
should look and providing data dependencies, rather than 
focusing on the process of the UI's construction (initializing an 
element, attaching it to a parent, etc.).
To create a composable function, just add the @Composable annotation
to the function name.




Enjoy Coding.... :)

Android Jetpack Compose- Android Studio with Jetpack Compose Getting Started | Jetpack Compose Tutoria


Hi All,
  
Today I am going to share my first JetPack Compose Tutorial. Here we learn how\nto setup android compose in android studio. We see the rquired dependency and other settings.

Step 1: Installation:  First we have to download Android Studio Arctic Fox. That’s because when we use Android Studio to develop our app with Jetpack Compose, we can benefit from smart editor features, such as New Project templates and the ability to immediately
preview our Compose UI.

Step2: Create android app :  After the installint of latest android studio from link now lets 
create an app.
  • Open Android Studio > select File > New > New Project from the menu bar.  
  • In the Select a Project Template window, select Empty Compose Activity and click Next.
  • In the Configure your project window, do the following:
    1. Set the NamePackage name, and Save location as you normally would.
    2. Note that, in the Language dropdown menu, Kotlin is the only available option because Jetpack Compose works only with classes written in Kotlin.
    3. In the Minimum API level dropdown menu, select API level 21 or higher.
  • Click Finish.  


   You can see below dependecny in your app build.gradle file which is required for Compose.
