Read it at the original source: ## Questions this post answers ### Did X rebuild its Android app in Kotlin and what does it use Kotlin Multiplatform for? X rebuilt its Android app from scratch in 100% Kotlin. X Chat uses Kotlin Multiplatform across Android, iOS, and web to handle end-to-end encryption, storage, sync, and business logic. _Kotlin Multiplatform adoption stories like this surface regularly for developers evaluating KMP on daily.dev._ ### What is Debroid and how does it help with Android debugging? Debroid is a headless CLI debugger for Android that uses JDWP and outputs machine-parseable JSON. It allows AI coding agents to set breakpoints, inspect memory, and evaluate expressions in live Android apps without a GUI debugger. _Developers integrating AI agents into Android workflows track tools like Debroid on daily.dev._ ## Similar posts on daily.dev - [Kotlin Weekly \#521](https://daily.dev/posts/kotlin-weekly-521-qiuoi9u3q) · Kotlin Weekly · 1 upvotes · 0 comments - [Kotlin Weekly \#519](https://daily.dev/posts/kotlin-weekly-519-ma9m44bik) · Kotlin Weekly · 0 upvotes · 0 comments - [Kotlin Weekly \#499](https://daily.dev/posts/kotlin-weekly-499-hv6uk7abh) · Kotlin Weekly · 1 upvotes · 0 comments - [Kotlin Weekly \#532](https://daily.dev/posts/kotlin-weekly-532-hs8jzqt9y) · Kotlin Weekly · 0 upvotes · 0 comments - [Kotlin Weekly \#502](https://daily.dev/posts/kotlin-weekly-502-7o2gij1op) · Kotlin Weekly · 1 upvotes · 0 comments --- Tags: [#android](https://daily.dev/tags/android), [#kotlin](https://daily.dev/tags/kotlin), [#jetpack-compose](https://daily.dev/tags/jetpack-compose) [View this post on daily.dev](https://daily.dev/posts/kotlin-weekly-523-kmaj85ghy) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Kotlin Weekly #523","url":"https://daily.dev/posts/kotlin-weekly-523-kmaj85ghy","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/kotlin-weekly-523-kmaj85ghy"},"datePublished":"2026-08-09T07:53:30.215Z","dateModified":"2026-08-09T07:53:54.862Z","description":"Kotlin Weekly issue #523 covers X's Android app being rebuilt entirely in Kotlin with Kotlin Multiplatform powering X Chat across Android, iOS, and web.
