 ### 🎉 New features
 
+- [build-tools] Add serve-emu web previews to Android Agent Device, Argent, and Appium remote sessions. ([#4270](https://github.com/expo/eas-cli/pull/4270) by [@szdziedzic](https://github.com/szdziedzic))
 - [build-tools] Add `ios_signing_backend` option to the repack step. ([#4239](https://github.com/expo/eas-cli/pull/4239) by [@gabrieldonadel](https://github.com/gabrieldonadel))
 - [build-tools] Support an optional `package_version` input on `eas/start_serve_sim_remote_session`, so a simulator session can pin the `@expo/serve-sim` version instead of always running `latest`. ([#4253](https://github.com/expo/eas-cli/pull/4253) by [@gwdp](https://github.com/gwdp))
