The latest Compose BOM and Compose 1.12

Add the BOM as a platform dependency, implementation(platform("androidx.compose:compose-bom:2026.09.00")), plus the same for testImplementation and androidTestImplementation, then declare Compose libraries without versions. Raising the BOM version updates all of them together. To use a different version of one library, keep the BOM and add a version to that single dependency; Google notes that pulling an alpha this way can also pull alpha versions of its dependencies. The Compose compiler isn’t part of the BOM: since Kotlin 2.0 it ships with Kotlin and uses the same version, so update it through Kotlin, see Kotlin 2.4 and 2.4.20.

The Compose 1.12 release notes state that Compose’s compileSdk moved to API 37 and that this means a minimum AGP of 9.2.0. So before moving to a BOM that brings Compose 1.12, set compileSdk to 37 and upgrade the Android Gradle plugin; if you are coming from AGP 8, follow the AGP 9 migration and the Gradle 9 upgrade first. Raising compileSdk doesn’t change your targetSdk; the Play deadline for that is a separate rule, covered in Google Play’s target API level requirement.

Fonts: downloadable Google Fonts can be variable and no longer need font certificates added by hand. Color: non-sRGB color spaces such as Display P3 set on Paint or a shader are preserved on API 29 and later. Graphics: MeshGradientPainter, drawn with hardware-accelerated Canvas.drawMesh, replaces Modifier.meshGradient. Autofill: a credentialRequest semantics property connects text fields to Credential Manager on API 34 and later. Sound: clicks and navigation play the platform’s interaction sounds, and SoundEffectOnInteraction turns them off for a subtree. Testing: onRootWithViewInteraction scopes Compose lookups to a View matched by Espresso, which helps with hybrid screens such as RecyclerView rows, and captureToImage() can include popups and dialogs with their anchor.

A current UI toolkit keeps your app polished; being found brings people to it. Censuus ranks apps by the visits they draw, and adding your app is free through the List my app form. Placement comes from traffic and sponsorship: apps climb on the visits they draw, and a sponsor can pay to rise higher. For navigation on Compose, see Navigation 3.
