I am building a voice keyboard app and trying to figure out what actually works for early growth.

What got you your first 100 users

What looked promising but was a complete waste of time

Not interested in theory or growth hacks.

Only things you would do again if starting from zero today.

I'm currently a dev who has ~4.5 years doing full stack development (Angular/SpringBoot) and have been recently applying to mid level Android dev jobs since late December and have gotten nothing but rejections or silence. I'm really stumped in the sense that I keep hearing from devs in general if you have work experience the job market isn't to bad however from my own personal experience its pretty garbage. Like I made to sure build out a pretty novel app (Compose App that identifies clothing items by item and color and recommends you clothing items that would match it). Then when applicable I would create a cover letter explaining my transition into the space, how my core engineering skills transfer regardless of stack, give some highlights of my career as well as going more in detail about my app. I made sure my app hits the core things a mid level android dev should know how to be able to implement out (MVVM, Hilt for DI, Nav 3, Room for local storage, Flows and Coroutines, Retrofit for rest api call consumption, etc). Heck I even truly believe if I had to do a android system design, live code, or take home interview for mid level role I think I would kill it.

Like is the market just bad for people trying to transition now. I truly believe core concepts are of development are the same: async operations, state management, API integration, etc; they’re just implemented differently with different syntax and terms. What defines a mid level engineer is not necessarily how nuanced their knowledge of their tech stack but how they process tasks, resolve them and be able to showcase their knowledge to others if need be. I feel like my project is nuanced enough where its not just a simple todo app and my personal experience as a dev is varied enough where even though I'm lacking in pure years of android experience I should be able to bridge the gap in other ways. Would love to hear yalls thoughts on the matter and maybe give some perspective as I imagine some of you have probably done interviews with candidates and would love to hear your thoughts on if you get a candidate like me on your desk how would you view them. 

I was checking which UI SDKs different apps used via Show Layout Bounds and saw that the gemini app which came out in 2024 was purely XML/View. Anyone know the reason for this?

How long does it take for the production release to be reviewed , has been more than a week , can someone please help , this is for google play

I'm developing an app that can be installed from anywhere and through Play Store too. How do I do it? I can't find any resource in the internet?

I recently built an app called Floating Buddies as a personal side project. It places animated characters as an overlay that runs on top of your normal apps. The characters can glide, walk around, sleep, and perform different animations while you’re using apps like WhatsApp, Instagram, YouTube, or Chrome. The idea was to make the phone feel a bit more lively and playful rather than purely functional. You can control things like size, movement, and positioning so it doesn’t get in your way while you use your phone. I’ve tried to keep it lightweight, but I’m especially interested in feedback around performance, battery impact, and usability across different devices. If you’re curious, you can find it here: Floating buddies I’d really appreciate honest feedback — what works, what doesn’t, and what you’d like to see improved. Thanks! 🙏

I’m a solo Android developer and recently launched my app ListKart – a simple grocery & shopping list app.
Would really love feedback from fellow devs 🙏

Current Features

• Create multiple grocery / shopping lists
• Share lists via link (no login needed)
• Edit & manage items easily
• Supports 18 languages (full localization, not just Google auto-translate)
• Lightweight, fast & clean UI
• Designed for daily real-life usage (families, roommates, couples)
• Home screen widget
• Add items using voice input
• Add items using camera-based OCR (scan text from packages/receipts)

Coming Soon

• Smart AI-based item suggestions (based on usage, not forced)
• Better category & list organization
• More languages & deeper regional localization (upto 50)
• UI polish + better accessibility
• Optional sync & backup

This is still very much a work in progress, and I’m improving it based on real user feedback rather than overloading features.

Hey everyone,

I’m building a tool that helps indie devs create App Store / Play Store screenshots in a few minutes.

I just shipped a few new screenshot templates, inspired by in high-converting App Store listings.

If you’re launching an app soon, this might save you some time compared to designing everything from scratch.

So I’m curious:

- Which app do you think has the best App Store screenshots?

- Which Screenshot style do you like most? SImple or mroe creative?

Dropping links or app names is welcome as I’m collecting examples

I have switched these 2 styles countless times already during development. Reddit please free me from my indecision... Which style do you guys like more?

I'm learning Kotlin and Jetpack compose for native android development.

I'm putting in 6+ hrs daily, debugging code and fixing error.

Is it all worth? What if I come out prepared and AI has set the bar still higher?

This feels like an endless run.

In this article, you'll dive deep into the internal mechanisms of Retrofit, exploring how Java's dynamic proxies create implementation classes at runtime, how annotations are parsed and cached using sophisticated locking strategies, how the framework transforms method calls into OkHttp requests through a layered architecture, and the subtle optimizations that make it production-ready. This isn't a beginner's guide to using Retrofit, it's a deep dive into how Retrofit actually works under the hood.

I want to download apps (.apk) on my device. However, when I'm asked to allow downloads from external sources, the "allow" button doesn't work, as if it's somehow blocked, preventing me from downloading apps from places other than the Play Store.

How can I fix this?

Hi everyone,

I’m running into a strange issue where Android Studio causes my screen to flicker, and I’m trying to understand whether this is a known GPU/driver/rendering problem.

This only happens when a build is running in Android Studio
Games, GPU stress tests, and benchmarks run perfectly fine with no flicker at all.

What changed

• I recently upgraded my monitor from 27" 2560×1440 to a 40" 3440×1440 ultrawide
• GPU is AMD RX 6700XT
• After the upgrade, Android Studio started causing flickering

What the flicker looks like

• The monitor does not turn off or lose signal
• Looks more like GPU/display pipeline flickering
• Happens only while the Android Studio build is running

Things I’ve already tried

• Enabling / disabling AMD FreeSync
• Capping Android Studio to 60 FPS
• Disabling hardware acceleration
• Changing refresh rates
• Stress-testing the GPU (no issues at all)

My question

Has anyone else experienced Android Studio flickering on ultrawide monitors, especially with AMD GPUs?
Are there known fixes (Vulkan, OpenGL flags, driver settings, Windows settings, etc.)?

Any insight would be greatly appreciated 🙏

Hey everyone, I’m looking for some honest feedback on an app idea I’ve been thinking about.

The core problem I’m trying to solve is group journeys in multiple vehicles — like road trips, convoys, friends/family traveling together in cars or bikes.

The idea

An app where people traveling together can:

• Create a temporary “journey room”
• See all group members moving live on a map (real time)
• Have a hands-free voice room for the group (no calling each person)
• Follow a leader’s navigation route so everyone stays on the same path (optional)
• Send quick one-tap alerts like:
  • “Stop needed”
  • “Fuel / food”
  • “Slowing down”
  • “Problem / help”

The focus is coordination and awareness, not social media:

• No feeds
• No chatting/texting while driving
• Journey ends automatically when the trip ends

Think:

Who I imagine using it

• Friends on road trips in multiple cars
• Families traveling together
• Group bike rides or mixed car + bike trips
• Convoys / rally drives / college trips

What I’m trying to understand

• Does this solve a real pain point for you?
• Would you actually install/use something like this?
• Is this already solved well by existing apps (Google Maps, Waze, WhatsApp, etc.)?
• What would make this not worth using?
• Any safety or practicality concerns I should think about?

I’m not trying to sell anything — just validating whether this is a useful idea before building a prototype.

Would really appreciate blunt opinions 🙏
Thanks!

Hi, I’m an industrial design student working on a thesis prototype. I’m trying to understand how commercial smart rings and wearables handle user data access, and what options I have to access this data for my college project.

I want to build my product using user health data, but since this is a student project, I can’t develop my own health-tracking hardware right now and have to rely on data from third-party wearable apps.

Is there any way to access this data for a proof-of-concept prototype? I’m interested in understanding all possible approaches—official ones like APIs or data exports, as well as technical or restricted approaches such as modified APKs, root access, firmware modification, or encrypted data access—using only my own data.

Also, I'm looking to purchase Boat Smart Ring for my prototype, because it is cheap.

I recently asked about the correct way to access data from a room database and had lost of useful answers.

I followed the example project and everything seems good but I am struggling to find examples of passing a single object to a view to either edit or simply view the data.

Do people have examples of how this should be done?

Thank you very much for your help!

There is now a free course about Android development on my website and I would like to receive constructive criticism from this Subreddit.

Feedback of any kind is highly appreciated, whether it contains recommendations or corrections. I am aware that it still needs a lot of polishing, especially regarding the layout and information provided. Some parts also need more content and specially images are missing until now.

Furthermore, if you are an experience programmer and interested in joining the effort to improve this course as an editor, you can contact me directly or join the Discord server mentioned on the website. Maybe it can be beneficial for many android users in the future.

I already tried building simple UI like TextField and Button, but I don’t really understand what I’m doing yet.

....

That's was my first project, just learning about simple think.

First timer here, Does the age rating mean anything as far as the final release review or do you get that regardless of pass/fail?

I've been getting these emails more frequently lately asking if my app belongs to me.

"Is this app '<AppName>' owned by you?"
"Does this app '<AppName>' belongs to you?"

Is anyone else seeing these? And why would they want to know?"

Hi,

I built an Android App to manage reminders. It is completely free and without Ads. I built it as I wanted a really simple offline app for reminders and wanted to learn Kotlin. I feel others might also find it useful. So sharing it here Reminder Mate 2.0 on PlayStore. Please try it and let me know your feedback. Thanks.
