Keep or embed a View when a required SDK component lacks a Compose equivalent or replacing a substantial existing renderer would add undue migration risk. Neither toolkit is inherently faster for every renderer: profile the implementation on representative devices.
How to choose between Compose and Views
| Decision factor | Jetpack Compose | Android Views |
|---|---|---|
| Direction for new UI | Android describes its approach as Compose-first. | The View toolkit is in maintenance mode; Android says it will receive only highly critical fixes. |
| Custom drawing | Provides Canvas and drawing modifiers, including drawWithContent, drawBehind and drawWithCache. |
Custom drawing uses the View-based Canvas; hardware-accelerated support varies by drawing operation and Android API level. |
| Using the other toolkit | Can host a View with AndroidView. |
Can host Compose content with ComposeView. |
| Performance evidence | Compose can skip phases when a change does not require them, though code can prevent those optimizations. No official head-to-head benchmark was established in the Android documentation reviewed. | Performance depends on the renderer and device; Android recommends profiling and testing custom drawing on actual hardware. |
Android says it will continue to support interoperability APIs, so adopting Compose does not require an all-at-once rewrite. The View toolkit’s maintenance status is not the same as a claim that existing View interfaces have stopped working.

What custom rendering looks like in Compose
Compose offers scoped drawing through Canvas and modifiers. Use them when the renderer needs to draw a graphic or visualization as part of a Compose interface, and use Compose layout and state to connect that drawing to the rest of the UI. Android’s documentation describes these APIs as using the view-based UI Canvas under the hood.

A change that affects only drawing may not need to trigger the earlier work. Conversely, coding patterns can prevent Compose from skipping phases that are not needed, so the API choice alone does not guarantee efficient frame updates.

When an existing View is the better fit
Retain a View when a required SDK component has no Compose equivalent, or when replacing a mature custom renderer would create disproportionate migration risk. Embed that component in Compose with AndroidView; use its factory and update behavior to create the View and keep it synchronized with Compose state.
For an existing View-based application, add Compose incrementally with ComposeView. Android recommends rewriting custom Views in Compose where possible, beginning with simpler components and moving toward more complex ones. This lets a team migrate piece by piece rather than replacing the interface in one release.
How to assess renderer performance
Do not choose a toolkit on the assumption that it is universally faster. Android’s performance guidance recommends profiling the actual app. For Compose, the draw measurement includes custom drawing performed in Canvas or draw modifiers; inspect the renderer’s real work and frame behavior on representative devices rather than treating toolkit-level claims as a benchmark.
For custom View drawing, hardware acceleration and supported operations differ across Android API levels. Test the drawing on actual hardware with acceleration enabled across the app’s supported device and API range. The official Android documentation reviewed does not provide a comparable Compose-versus-Views benchmark, so no general speed percentage can settle the choice.

- Starting a new renderer: choose Compose if its drawing APIs and the components the renderer needs cover the job.
- Relying on a View-only SDK component: keep that component and host it in Compose with
AndroidViewwhile the rest of the screen uses Compose. - Maintaining a View-based app: introduce Compose with
ComposeViewwhere it is useful, then migrate custom Views incrementally when replacement is practical. - Evaluating performance: profile the renderer’s actual frame work on the devices and Android versions the app supports; test View custom drawing with hardware acceleration enabled.
This comparison does not establish that one toolkit is categorically easier or more capable for every custom renderer. The practical choice depends on the required components, existing implementation and measured behavior. The Android documentation cited here also does not settle accessibility or testing differences for custom renderers.
