🚀 CodeAssist 3.5.0

LAYOUT PREVIEW

Tap to edit - tap any view in the live layout preview to open a visual attribute editor (a bottom sheet on phones, a docked panel on wide screens). It edits the real XML, so the Code view and the preview update together as you change things.
Each attribute gets the right control: a switch for true/false, chips for enums and flag combinations, a dp field (with wrap_content/match_parent chips) for sizes, a color swatch for colors, and a text field for the rest.
Add attribute opens a searchable picker that only lists attributes the selected view actually supports (framework + your own custom views), and auto-declares a missing xmlns when you add an app: attribute.
Typing a value gives the exact same auto-complete you get editing the XML by hand.
New one-time "Prepare libraries" panel: the preview now tells you when a project's libraries still need preparing (and how many) with a one-tap prepare step, instead of silently stalling on the first render. It no longer redoes that work on every render.

ANDROID XML

Code folding - collapse any element's body and multi-line comments in layouts, manifests, and resource files.
Parameter hints inside attribute values - put the caret inside an attribute's quotes and see what it expects (true/false, the enum/flag members, or the resource type like @string/...).
Your own custom View subclasses now show up as layout tags (even before they are compiled) and inherit the android: attributes of the framework widget they extend.
Theme references (?attr/colorPrimary, including Material/AppCompat) now complete - type ? to bring them up.
New inspection: a duplicate attribute on the same tag is now flagged.
XML is now parsed with IntelliJ's XML PSI, the same engine Android Studio uses, so tags, attributes, and value ranges are recognized more precisely (and it stays error-tolerant on half-typed files).

KOTLIN

Much smarter type inference - a new constraint-based engine (K2-style) infers types through generic call chains and scope functions. sumOf/maxOf/minOf { } now resolve to the correct Int/Long/Double overload based on what your lambda returns.
Builder inference - buildList/buildSet/buildMap/sequence/flow { } infer their element type from what you add/put/yield inside, even through if/for/repeat.
Generics variance (out/in/*) is now respected in completion and subtyping.
Highlighting: this/super are colored as keywords everywhere (including inside string templates and when labeled like this@Outer), and a lambda's implicit it is colored as a parameter.
A batch of completion fixes: map.forEach entry types as Map.Entry (so .key/.value complete), x!! yields the not-null type, StringBuilder/StringBuffer members, Array(n){}/reduce/IntRange element types, and mixed numeric arithmetic (Int * Double) widens correctly.
Fixed a with/run/apply regression where members of the receiver inside the block could resolve incorrectly.

ANDROID BUILD

Build your own .aar library modules - Android library modules now assemble a real .aar (per variant) containing the classes, manifest, resources, R.txt, assets, native libs, and consumer ProGuard rules a consumer needs. Assemble it straight from the Run picker.
Console / plain-Java projects no longer see android.* - each module now resolves its own platform SDK, so a Java/Kotlin console or library module compiles, completes, and error-checks against the core Java platform instead of android.jar (no more spurious android.* suggestions). You can also pick a module's Platform SDK in Module config.
Fixed corrupted .aar extraction: a dependency .aar interrupted mid-extract is no longer treated as complete and reused (which caused missing resources/assets) - it now re-extracts cleanly.

EDITOR & STABILITY

Fixed the top on-device editor crash - shortening a file could throw ArrayIndexOutOfBounds when the renderer read a line number captured a frame earlier; line lookups now clamp safely and self-correct.
Fixed a crash when copying a long build log to the clipboard (TransactionTooLargeException); the copy is now capped while keeping the end of the log, where the errors and final status are.
Smart backspace - Backspace at an indent stop now removes a full indent level instead of one space at a time.
Sample-project images and other binary assets are now created byte-for-byte instead of being corrupted, and large/binary files are no longer overwritten by the editor.
Faster folding - fold regions are cached and reused while the buffer is unchanged, instead of reparsing on every folding pass.

BUILDS & NOTIFICATIONS

Notification permission is now asked the first time you build (with an explanation of why the isolated build shows a progress notification) instead of at launch. Decline and builds simply run in-process; you can re-enable it later in Settings → Build Runtime. It only prompts once.

SUPPORTING CodeAssist (ADS), FREE TO TURN OFF

CodeAssist now shows lightweight native ads on Android only (never on desktop), in a few calm, between-tasks spots: below the project list, one card in the Projects store, the Learn tab, and the build console footer while nothing is building. No pop-ups, no interstitials, nothing over your work or a running build.
You can turn ads off for free, no payment, ever. On the project picker's "Support CodeAssist" card there is a single "Show ads" toggle; switch it off and ads never render again (your choice is saved).
There is deliberately no paid "remove ads" purchase. Removing ads is free; supporting the project through the optional Sponsor / donation button is completely separate and always optional.

ANALYTICS

Still opt-in and performance-only - it never collects your messages, file names, or content, and there is no new personal data. Behind the scenes, failed builds are now tagged by category and crash reports always pin a line of app code, so problems are easier for us to diagnose.
