Am I the only one facing this issue with Copilot in Android Studio?

Needed to make some tweaks and some additional features in my old app which I kind of manually coded with a bit of AI usage.

Now, as usual I prompt in all required changes and it's on this loop of adding and deleting stuff, the app isn't even that big.

It was done once but as soon as I tried to build, errors shown up

So , I asked AI to resolve it but it's been like 2 hrs now , no progress, I would've manually been done by now.

Is it only copilot thing or just common behaviour,might shift to another model now.

Startup app security

I’ve noticed a weird gap in the app ecosystem.

Enterprise companies have AppSec teams, dedicated security engineers, and expensive tooling.

Most indie developers and startups don’t. We’re trying to ship features, fix bugs, market the product, and security often becomes “I’ll come back to it later.”

I’ve been building a security platform with those smaller teams in mind, and I’d rather have real developers using it than trying to guess what people need.

So I set it up to give the first 50 organizations free Team access. No codes, no DMing me, no application, just sign up and claim it if it’s still available.

Strata-security.com

The trade-off is simple: use it on your projects, and if you run into bugs, false positives, confusing UX, or features you’d like to see, let me know. I’d much rather improve it with real-world feedback than build in a vacuum.

Even if you never use my platform, I’m curious, what’s the biggest security challenge you’ve run into as an indie developer or startup? Is it mobile apps, dependency management, secrets, CI/CD, or just finding time to think about security at all?

Identity of Composeable instances

In https://developer.android.com/develop/ui/compose/lifecycle#composition-anatomy
, they explain that the identity of a composeable instance is its call site, which they define to be “The call site is the source code location in which a composable is called. This influences its place in Composition, and therefore, the UI tree.”

I understand this as being the place in the source file where the composeable is called. But I find that there must be more to it than that, as it’s hard to imagine a robust, efficient system that literally keeps track of the exact line of code where each composeable gets called for a composition. For example, the compiler would have to build out a table for every composeable and store it as part of the build, and if the composeable never gets called in the user session, then it’s just storage space being wasted. I assume the identity of each instance of a composeable is established during initial composition where the Compose layout system behind the scenes builds out some kind of a tree to see the composeables and their location relative to other composeables in same function. Just looking for insights.
Thanks!

A CLI Tool to Audit and Auto-Fix Android Gradle Performance Issues Open Source

I built a CLI tool that audits Android Gradle performance problems and safely fixes them.

Unlike the usual build-speed advice that's all manual, it detects bottlenecks across config cache, build cache, Kotlin incremental, daemon and parallel execution, then applies reversible fixes with a dry-run preview. It also covers KMP and Flutter Android projects, and has CI/CD and an simple webpage dashboard. Just try

npx droidperf audit /path/to/project

Made an open source tool to stop multiple adb clients (AI agents, scripts, Studio) from fighting over the same device

I kept running into an annoying problem with multiple Claude Code sessions on the same machine.

I'd have two Android app apps building by two or more claude sessions, usually with one or two phones plugged in. Both agents were doing the usual install → launch → screenshot verification loop over ADB, and they kept picking the same device at the same time.

The result was chaos:

Agent A screenshots Agent B's app and assumes its own app crashed or something has happened.
It reinstalls and/or relaunches.
Agent B does the same.
Both end up stuck reinstalling and relaunching over each other.

adb -s lets you target a specific device, but there's no ownership or queuing on top of the shared ADB server. Nothing prevents multiple independent processes from trying to drive the same phone.

So I built AdbHarbor.

It works as a broker that sits on port 5037 (the default ADB server port) and moves the real ADB server to 5038. Since every ADB client already connects to 5037 by default, existing tools—including adb from any path, Maestro, ddmlib, Gradle, Android Studio, etc.—work without any configuration changes.

Features:

One device lease per session.
Automatically identifies sessions by walking the client's process tree back to the owning agent.
Other sessions wait in a queue.
Read-only commands (getprop, pm list, etc.) bypass locking.
Stale leases are reclaimed automatically if the owning process crashes.
acquire --any atomically picks a free device and returns its serial, so multiple agents naturally spread across a device fleet instead of all grabbing the same phone.

One funny bug while recording the demo: both Claude sessions sat waiting for three minutes because my scrcpy window had already taken the lease. 😅 That led me to add an observer mode so screen mirrors never acquire exclusive device locks.

I'm curious how other people solve this problem. If you're running multiple AI agents, CI jobs, Android Studio, or other tooling on the same machine, how do you avoid device contention? Is everyone just relying on "one device per tool" by convention?

What do you think about this monetization approach?

I'm working right now on publishing my first Android app.

This is supposed to be a paid app that will be fully on-device with no ads or tracking.
This is a dialer/launcher type app.


The initial approach is:
\- search is always for free,

\- first 20 actions on contacts or apps are free

\- afterwards a 30-day Google Play free trial (card required in Google Play but otherwise free) leading to an annual subscription worth roughly a coffee at a coffee shop

or a

\- lifetime purchase worth roughly 4 years of subscription.


What do you think about this approach?

Submitted my first ever game!

I've been working on a hypercasual mobile game for about 3 months now, with zero experience. It has been a long journey with MANY frustrating moments. It went from just a small side project to something I was working on every single day after work. I'm so invested in this that I even created my very own LLC. Now all that's left is to wait on Apple, and start my google play submission! Will update my status.

Career switch to Android in 2026 – Looking for advice from Android developers

Hi everyone,

I'm 24 and transitioning from web development (React/Next.js) to native Android development with Kotlin and Jetpack Compose.

My goal is to become employable as an Android developer over the next few months by studying full-time and building production-quality projects.

For those already working as Android developers:

\- What skills should I prioritize?

\- What projects actually stand out during interviews?

\- Is there anything you wish you'd learned earlier?

I'd really appreciate any advice.

API 37: Valid values of typeMask (for WindowInsets) have disappeared?

After upgrading from API 36 to 37, Android Studio puts a red underline on the typeMask parameter of WindowInsets.getInsets. The message on hover is "Must be one or more of:" followed by literally nothing.

In the latest documentation, the list of valid base values of typeMask seems to have disappeared for every relevant method of WindowInsets.

- Before change: <https://web.archive.org/web/20260208222401/https://developer.android.com/reference/android/view/WindowInsets#getInsets(int)>
- After change: <https://web.archive.org/web/20260213235548/https://developer.android.com/reference/android/view/WindowInsets#getInsets(int)>
- Screenshot of comparison: <https://imgur.com/a/AnuxRP4>

My code still compiles and the behaviour seems to be right (I'm using it for edge-to-edge bottom padding of a keyboard), but the red underline is really annoying.

Do I just have to wait until someone restores the list of valid typeMask values?
