because I was tired of scattered notes and spreadsheets.
I made a FREE version first to see if it helps others.
If anyone wants it, I can share the link....

TWA (Play Store PWA) shows URL bar on scroll — GitHub Pages + assetlinks.json confusion
[Image attached in comment. ]
I’m publishing a PWA to the Play Store using Bubblewrap / TWA. The app works, installs, and launches fullscreen — but when the user scrolls, a top bar appears showing my GitHub Pages domain.
I’ve already done the usual fixes:
• Added /.well-known/assetlinks.json (correct package name + SHA)
• Verified it loads in the browser
• Added .nojekyll at repo root
• Tried _config.yml include rules
• Tried GitHub Pages via branch deploy and GitHub Actions
• Static HTML...

Guides/Tutorials on Cardboard SDK on Android Studio
Does anyone know of any guides, tutorials or resources in general for the Cardboard SDK on Android Studio? The official quick start guide is good but it gets hard to understand some further concepts. For example, for an SDK that expects you to know OpenGL to such a low level, why would they offer some higher code on their API such as a 3D mesh struct (this is on their C API)?
If anyone knows of anything id be glad to know about it too!...

Project Files Vanishing
So, for context, I've just started using Android Studio, and I'm using it for code from an established repo. Problem is, the files keep disappearing. Every time I hit "Sync Project With Gradle Files," the files show up as they should (image 1), but if I switch windows and then switch back, the files will be there for a split-second and then disappear (image 2). What's going on? Has anyone else had this problem? If so, how did you fix it? I've spent hours scouring every possible thing I could, fr...

Screenshooting doubles FPS on LOVR + Monado VR application
I'm on a deep dive into Virtual Reality these days, and I started tinkering with LOVR and Monado on Android. The thing bugging me is that when I set my application supersample parameter to .33 and screenshot while running on my Xiaomi Redmi 13, the frame rate goes from 30 to 55-60!

Need cheaper iOS design reference tool. screensdesign alternative?
I'm building android app rn but I'd like to get inspo from ios side cause let's be honest most polished apps are ios first lol also feels more premium and conversion-focused.
I know Screensdesign is like the best ios design library out there - video flows, business metrics, onboarding analysis, etc...but its kinda pricey for side project budget.
Mobbin doesn't have the metrics, Dribbble is just concepts. Anyone know cheaper options that come close? ...

Actual Offline PDF Editor like Word Processors.
Hi everyone,
I’m currently working on a small Android project called RevPDF. The goal is to make it easy to do quick PDF edits (like resumes) directly on your phone, without creating an account or uploading files anywhere. Everything runs offline.
It’s still early, but the focus is on keeping the original font and layout intact, so edits don’t feel “reconstructed” like many mobile PDF tools. I built this mainly for myself and people who need to make fast change...

What should be the structure? Say I want to store the parent having children ( one to many), this is one set. Like that, there will be n number of sets. Obviously, no child should get involved with other parents and children, and an individual parent should be able to access their children. (The child will be allocated to the parent, depending on some attribute.)...

Has anyone tried the new Gemini-powered auto-translation in the Play Store Console? How's the quality?
Hi everyone,
I recently noticed that Google integrated Gemini models to automatically translate app strings directly within the Play Console.
As a solo developer working on a niche engineering app with lots of technical jargon (terms like "decompression flow", "orifice sizing", and "free-fall analysis"), I’m a bit hesitant to rely purely on AI for localization.
For those who have tested it:

How do you handle currency conversion in mobile apps?
If you you are building an app that has users from different countries:
\- How do you handle currency conversion?
\- Where do you get exchange rates from?
\- How often do you update them?
\- Have you ever had issues with wrong or stale rates?
I am not selling anything, just trying to understand how people handle this in production....

Liquid glass controls?
I'm trying to code an iOS calculator app and want to implement liquid glass (I know it's not for everyone but I kinda like the look). Is there a library out there with buttons and other controls that have liquid glass and the iOS 18 animations, so it looks like the newest iPhones? Or do I have to do this from scratch?

How can I find out which API an Android app uses with Genymotion?
Hi everyone,
I’m new to Android development and mobile app analysis, so please excuse any beginner mistakes.
I haven’t used any tools yet. I’ve only done some research and learned that Genymotion is commonly recommended as a good Android emulator, especially for testing and analysis. That’s basically where I am right now.
What I’m trying to learn is:
How an Android app communicates with its backend
How I can identify which API endpoints an app is using (URLs, requests, responses)

How would you design onboarding for a kids learning app?
I’m building a kids’ learning app for ages 3–7 on Android and want feedback on the **onboarding UIUX** (Grow little kids ).
Goals:
* Make it clear it’s educational, safe, and ad‑light
* Very simple, parent-friendly first‑run experience
* Let parents set age/level quickly without a long sign‑up
Current idea:
1. Screen 1 – welcome [Grow little kids](https://growlittlekids.in/)
2. Screen 2 – learning focus (rhymes, alphabet, numbers, colors)
3. Screen 2 – with age ranges (3–4, 5–6, 7+)

Issues on my nothing phone (2)
yesterday my NP2 suddenly crashed and hasn't been able to turn on since. It keeps trying to boot up then a "crashdump" screen appears and then it tries to boot up again. The only way i found to stop that loop is to power off the device through fastboot mode, i tried everything, even doing a factory reset but to no avail.
the crashdump screen is the same as on the attachment
