Compose Title Log For Free

Jetpack Compose is Android's modern toolkit for building native UI. It simplifies and accelerates UI development on Android. Quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs.

The key benefits of Jetpack Compose are that it speeds up testing and uses a single code base to write code. There is, therefore, less chance of producing errors. Let's look at the User Profile Image app that loaded images, and information about users from a rest API, using an intuitive design.

This can slow the app on startup, and whenever it uses a library feature for the first time. You can improve performance by defining baseline profiles.

For compose-based layout, the slow frame rate came out to be 8.91% whereas it was 9.93% for XML-based layout. Like frozen frames, ~10 out of 100 frames would fall under the slow frame category for XML-based layout. Whereas it was ~9 out of 100 frames for compose-based activity.

Android UI development is now more powerful. Few years back, before Jetpack compose, developers were using XML layouts to build native UI. When we build screens with XML, we have a very dependent structure.

Compose works with the aid of a Kotlin compiler plugin in the type checking and code generation phases of Kotlin: there is no annotation processor needed in order to use compose. This annotation more closely resembles a language keyword . A good analogy is Kotlin's suspend keyword.

This section lists a few best practices to help you avoid them. Use remember to minimize expensive calculations. Composable functions can run very frequently, as often as for every frame of an animation.Use lazy layout keys.Use derivedStateOf to limit recompositions.Defer reads as long as possible.
