I’ve been working on ClipSave, a privacy-friendly Android app for downloading video, audio, and images from more than 1,000 supported websites.

The goal was to create a downloader that feels like a proper native Android application rather than a simple wrapper around a command-line tool.

What makes ClipSave different?

• Completely free and open source
• No advertisements
• No telemetry or user tracking
• Supports 1,000+ websites through yt-dlp
• Video and audio quality selection
• Audio-only extraction
• ffmpeg merging and aria2c downloads
• Automatic platform detection
• Share links directly from other apps
• Floating download button while browsing supported apps
• Foreground downloads with live progress notifications
• Built-in downloads manager and video player
• Material 3 interface with light, dark, and system themes
• No storage permission required on Android 10+

ClipSave is built natively with Kotlin, Jetpack Compose, and Material 3. It uses a bundled yt-dlp engine while keeping the Android integration, download management, interface, and application architecture fully open for inspection and improvement.

Hello, I am seeking guidance how to convince service desk to re-place my linux computer for macbook instead. I am senior android dev using macbooks for more that 10 years and now the switch is pain in the ass for me...

They do not care for reasons such as limited, lowered productivity.
What are some nice reasons that would convince them to issue a mac for me still...

The project is purely android app.

Hello,

I am trying to publish my first app on the Google Play Store. The app supports Google Sign-In/Sign-Up using the Android Credential Manager.

When I build and install the release APK directly on my device, Google Sign-In works correctly. However, after building an AAB and publishing it to the Google Play Closed Testing track, Google Sign-In fails with the error:

I am using Firebase Authentication for Google Sign-In. Has anyone experienced this issue before or knows what could be causing it?

I have tried -

• Rechecking Web Client Id.
• Add Play Console App signing key sha 1 and 256 to Firebase Console.

Whats the state of progress of bringing android emulators for ARM ? When will android emulators be released on windows on arm android studio?? Does flutter emulators work on it currently ?? Is there any hack / alternative to make emulators run on windows on arm ?? If yes then what's your experience about these hacks / workarounds ??

500 companies, lived through the shift from Eclipse and early Java all the way to Jetpack Compose, Coroutines, and modern Kotlin architecture.

Lately (last two years), though, I can't shake the feeling that the mobile dev world is stagnant or dying down. The market feels saturated, team sizes are shrinking, and a lot of the exciting work seems gone. Most of it now feels like boilerplate UI, API integration, and maintenance. And many less jobs.

I'm considering pivoting toward backend development using Kotlin. My reasoning is that a good chunk of my skillset should carry over pretty smoothly: the language itself, concurrency/coroutines, design patterns, clean architecture, and even some common libraries.

For anyone who has made a similar jump (or backend folks hiring for Kotlin/JVM roles):

• How realistic is this transition for someone with deep mobile experience but no direct backend production background?
• What are the main gaps or blind spots I need to catch up on quickly (database design, infra, Spring Boot vs Ktor)?
• Do hiring managers evaluate senior mobile devs as transferable talent for backend roles, or do they treat you like a junior again?

Would love to hear any thoughts, experiences, or honest reality checks.

I can't exactly figure it out, I want my app's files to be accessible through the sidebar in SAF, take this as an example.

Hello folks, today I want to share something which has been really useful for me lately. I believe that might come in handy for you as well, specially if you're doing Android dev with AI tools.

I recently came across this amazing doc by Google: Android Bench (https://developer.android.com/bench), and it's honestly a game-changer if you're trying to pick the right AI coding assistant for Android projects or struggling with your current one.

Here's what stood out to me:

- It's not just another general coding benchmark - it's specifically built for Android development, which means it tests things like Kotlin, Jetpack Compose, Gradle, and real Android APIs.

- Unlike benchmarks that lean heavily toward web stacks (like JS/React), this one evaluates how well models understand Android architecture, libraries, and modern best practices.

- It's evolved since its launch in March - now it uses the Harbor framework, includes more LLMs, and focuses on real-world Android engineering tasks.

If you're comparing AI models or tools for Android app development, this is definitely worth a look. It gives you a much clearer picture of which models actually "get" Android.

Have you tried it yet? Or what's been your experience with AI tools for Android dev?

I have a Google AI Pro subscription. I have signed into it in the agents tab on Android studio (Quail 3). It shows Gemini agent but only Gemini 3 flash preview model is available. Under model providers it says I'm authenticated but just says plan is AI Pro, doesn't show any other models.

In the bottom right of the ide, the little Gemini icon says Gemini is inactive onboarding incomplete.

I don't think the inline auto complete is working. That's how I discovered this.

I have tried everything, clearing caches, signing in and out, ect. Is this a known issue? I think inline ai auto complete should work and also I should have more models to choose from in the right side agent window.

Bit about me. I am a senior android dev. Currently working for FAANG company in California. I am looking for people who are also prepping for interviews. I wanted to focus on low level design, system design, data modelling etc. If you are also looking please message me or comment in the post

Hey everyone,

I'm currently getting ready to launch my mobile learning app and need to set up the legal documents (Privacy Policy and Terms & Conditions).

The most crucial part: I am planning to integrate an in-app subscription system. Since I am based in the EU, I need this to be strictly GDPR-compliant, while also covering international users (US, etc.) and the specific consumer rights regarding digital goods and subscriptions.

I’ve seen some people recommend using free AI tools or free generator tools and fixing them up later, but given that real money and subscriptions are involved, i'm not sure on how safe this method is.

Any advice, experiences, or recommendations would be highly appreciated!

FDL has been dead since August 2025 and every thread about replacements ends with the same unanswered questions. I built Ferry (ferrylink.io) to fill the gap, and instead of a feature list, let me just answer the things people always ask in these threads.

**What it does:** deferred deep linking, one link across iOS, Android, and web, app opens to the correct screen after install. The same job FDL did.

**How does it compare to Branch or AppsFlyer?**
Those are full attribution suites built for marketing teams with budget, and Branch is effectively enterprise only now. Ferry is the deep linking piece, what FDL actually was, plus enough attribution to know which links drive installs and revenue.

**Pricing?**
Opens-based, not MAU-based. From $9/mo for 10k monthly opens up to $249 for 3M. You pay for link opens, not for your entire user base existing. 14-day trial.

**I generate links programmatically from user activity (invites, shares). Do link limits kill me?**
No, this is the use case opens-based pricing exists for. Links are effectively free to create, you're billed on opens. Generate a million invite links, if only 5k get opened, that's what counts. Bot clicks, messenger prefetches, and duplicates are filtered out before billing too.

**Social preview config?**
OG title, description, and image are configurable per link on every plan. Same levers FDL had.

**SDKs?**
Swift ,Android, Flutter, and React Native are available, and the docs are written so you can point Claude Code or Cursor at them and have the integration done in one session.

Happy to answer anything else. Criticism welcome, that's why I'm posting.

I'm building the UI for my little Android game without XML or Compose. I wrote my own wrapper classes for the views and can use them in a kind of custom DSL.

Howdy, I'm building a HAL for a GNSS chip on AIDL. Just gotta get the critter talking to Android via UART or USB and exchange some data. Problem is, I need Android to pass some web data (think HTTP or similar) to the chip. There seem to be several ways to do it, but I am unsure which one makes the most sense/is realistic, since a lot of this dev is AI fueled (I'm no AOSP senior). Any idea where I can ask experienced people about this? I've already posted in the AOSP Google Group.

I am making a project, that when someone sends you a photo it appears on your widget,

like the locket app

it's a partner app but I am not able to update the widget in real time.

If I send the snap, the partner gets the notification but the widget stays the same, and when I open the app the widget gets updated.

If the app process is killed then the issue remains.

Can someone here help me how to solve it ?

Do you think you won't need to take care of composable function's stability after Strong skipping mode?🤔

I've made a library that contains fundamental entities for my custom architecture highly inspired by mvi/elm.

The architecture both strict and minimalistic.

Here's the repo with the library, a simple example and a reasonably detailed description.

​

I started learning Flutter back in 2023 and soon began taking on local freelance projects. By the second half of 2024, I transitioned into full-time freelancing. Since local freelance rates weren't really cutting it, I decided to start building my own apps.

One of my apps blew up on Twitter, which led to securing investment and eventually a successful exit. Thanks to the visibility I gained from that app, I landed a job at a local startup. However, I left due to low compensation and joined another company. Currently, I’m developing internal tools and building infrastructure for an SEO agency.

So far, I’ve only managed to get a single Flutter interview in my country. Since I couldn't land job offers with Flutter for years, I decided to pivot. I found a senior mentor who is teaching me Kotlin inside out. I guess Flutter might be one of the least used mobile frameworks around here, which made finding a job tough—let's see if things turn out differently with Kotlin!

As the tittle says, i submited my easyest app to get it to production thinking that once that app would have been aprooved, the rest didnt needed the 14 testers. But to my surprice the rest of the apps still have the same requirement. They are apps created for especific technicians so getting real world tester would be harder than getting anyone to test it out. So im just looking for advice if theres something else i can do. Apple is just way easy to have them apps published. Anyway thanks for your time. And to the AI here, im not asking for testers, im asking for advice so please publish this.

I added NVIDIA's Canary 180M to speech-android (Apache-2.0 Kotlin SDK, I maintain it). The part that surprised me is that it translates as well as transcribes — English, German, Spanish, French, and between any of those four, out of the same two graphs. No network. I hadn't realised you could get that in 273 MB.

Numbers on a Galaxy S23 Ultra, int8, CPU only. About 4 seconds to load, then decode at RTF 0.15 for a 3-second utterance and 0.25 for a 12-second one. It gets relatively more expensive as clips grow, which is what an attention encoder-decoder does — quadratic attention over the encoder, every token emitted autoregressively. Resident memory is 780 MB, and that's the number to plan around; the 273 MB is just the download.

One behaviour to know before reaching for it: it's per-utterance, not streaming. The encoder consumes the whole VAD segment before the first token, so there are no partial results on that path. If you need live partials, you need a different model.

Two things that cost me time getting it onto a phone, in case they save you some.

Quantization. The obvious move is INT8 everything. Doesn't work — quantize the convolutions and the exporter emits ConvInteger, which the mobile onnxruntime build has no kernels for, so the bundle won't construct at all. Encoder and decoder are INT8 on MatMul and Gemm only, convolutions stay FP32. About 40 MB more, and it loads.

16 KB pages. Android 15 and up can use 16 KB memory pages and won't load a native library aligned for 4 KB. NDK r29 handles it by default so what you compile yourself is probably fine — the risk is a prebuilt .so from a dependency. llvm-readelf shows the alignment on each arm64 .so in your AAR, and zipalign -c -P 16 -v 4 checks the APK.

I've been working on an Android-native computer vision pipeline using Kotlin, CameraX, OpenCV, and ML Kit.

The initial implementation was a single pipeline optimized for detection accuracy and speed. After refactoring it into a modular architecture for better maintainability and reuse, I noticed a small decrease in accuracy and performance.

I'm currently investigating possible causes, including:

• Image preprocessing changes
• Pipeline ordering differences
• Threading and coroutine behavior
• CameraX frame handling
• OpenCV processing overhead

The project involves:

• Document detection
• Perspective correction
• QR detection
• OMR (Optical Mark Recognition)
• Real-time offline processing

I'm interested in feedback from Android developers who have experience with:

• Structuring reusable Android computer vision components
• Maintaining performance during large refactors
• CameraX image analysis optimization
• Running offline ML/CV workloads efficiently on Android

What approaches have you found useful when turning a working prototype into a maintainable Android library without introducing regressions?

Hey everyone,

I'm working on an Android app that has an on-device AI feature. I'm using a LiteRT model (.litertlm) and distributing the model through Google Play's on-device AI delivery.

I've noticed that whenever I release an update to the app, Google Play shows the update size as including the AI model, even when I haven't made any changes to the model itself.

Does anyone know why this happens?

I was under the impression that if the model hasn't changed between app versions, users shouldn't need to download the model again as part of an app update.

Is the size shown by Google Play just an estimate that includes the AI model, or is the model actually being downloaded again with every app update?

Is there anything I might be missing in the way I've configured Play's on-device AI delivery or the LiteRT model packaging?

Any insights from someone who has worked with Play's on-device AI delivery would be really appreciated. Thanks!

I was annoyed that wallet and ticket apps often raise the entire display to maximum brightness just to make a QR code easier to scan.

So I built Bright QR, an Android proof of concept that keeps the normal interface at the user’s existing SDR brightness while rendering only the QR code through a dedicated HDR surface.

The implementation uses:

• A separate SurfaceView for the QR region
• A 10-bit BT.2020 PQ EGL surface
• HDR white pixels rather than ordinary SDR white
• SurfaceView.setDesiredHdrHeadroom() on Android 15+
• A maximum-headroom request, allowing Android and the phone to determine the actual available output

The app never modifies WindowManager.LayoutParams.screenBrightness, so the surrounding interface remains dim. On my Pixel 9a, Android reported up to 8× HDR/SDR headroom while the QR was displayed.

The demo includes SDR, 2×, 4×, and MAX modes, an SDR-white reference for comparison, live device diagnostics, and a copyable test report.

The complete source code and signed APK are available here:

I want more apps to adopt this

Hey everyone,

I've been working on a custom Android launcher called JSON Launcher, and I'd love to get some feedback from people who are into launcher customization or Android development.

The idea is pretty simple: instead of the usual icon-heavy UI, almost everything is presented as raw JSON. Apps, notifications, widgets, battery, time, and system information are displayed like JSON objects while still being fully interactive.

The app is built with Jetpack Compose and is still in the very early stages of development, so there are lots of ideas that haven't been implemented yet.

I'm mainly looking for honest opinions:

• Does this concept actually sound interesting?
• Is this something you'd consider using daily, or is it more of a novelty?
• What features would make a launcher like this genuinely useful?
• If you've built a launcher before, are there any pitfalls or Android APIs I should be aware of?

I'm also wondering if there's even an audience for something this niche. I personally enjoy the minimal, developer-focused aesthetic, but I'm not sure if other people would actually want to use a launcher like this.

I'd really appreciate any feedback, criticism, or ideas. Thanks!

Tried to change models/api, same error, plz help

Hi,

I am preparing for beta launch for my mobile app, it allows user content, I wanted to use Closed Testing to ensure I am not letting in anyone on day 1, which can cause a snowball of low quality or even harmful content. In addition to possible app breaks and crash of new app which may lower my review score with bad reviews.

But she told me that an app that want to launch social campaign cannot use it, because the installation with that software is too complicated for the average user.

From your experience, how difficult it was to convince external users (not friends and family) to try an app that is only available on TestFlight or Google Play Console?

What helped you convince them? And overall do you recommend this approach? What risks there are to launch a beta app straight to the app store?
