Some questions about Android Studio
Hey guys,
I'm pretty new to Android Studio and am implementing a simple BLE framework(empty activity) from various tutorials online, mainly the one published by the official Android website. I see that I am getting a lot of errors in any place where code snippets including gatt/bluetoothGatt is mentioned, and while my exact mainActivity code runs perfectly well in my friend's android studio, it doesnt work on mine(when I run on my emulator or phone, the app immedeatly crashes).

Microphone Foreground Service
Hi there! I am trying to build an app where I have a Recorder class, a RecorderViewModel and Recorder Screen, to divide logic from UI. My problem comes when I try to build a Foreground Service for a notification where I want to also control the Recorder. My question is: Where should I call the recorder functions: in the viewmodel or in the service? Thanks in advance...

App rejected due to crash but unable to reproduce or see any crash logs in Android Vitals
I'm trying to publish an app however it got rejected twice due to
Violation of Broken Functionality policy - The app opens, but it keeps crashing
I'm not able to reproduce this crash on any of my devices nor the emulator. It's also not reporting any crash in Android Vitals so there's no evidence of any crash logs there. Any suggestion on how to go about this or using another tool which might show me where the crash is happening if I submit it for review again....

Is there a way to implement guards/redirects for deep links in NavHost?
Let's say I have an app, with a deep link to a screen user can only view if they are signed in, and if they get deep linked while not signed in, I want to have them redirected to a sign in page, where after successful sign in they get redirected to the screen they were initially meant to go to.
What's the proper way of doing this?
In Flutter go_router package, I could just use code like:

if (!isSignedIn) {
return '/sign-in?redirect=${state.uri.path}';

TextFieldState for query textfield in search with pagination
I have a screen with search text field and pagination.
And I found it much more practical to avoid TextFieldState!
I have a loadData function, and it's very convenient to simply call it in viewModel's onEvent for both Search and LoadMore events, to update my uiState StateFlow.
However, with TextFieldState, i have to create a snapshot flow, that I then need to observe in LaunchedEffect, considering dispatcher, lifecycle, and with overall disadvantage of observing an obscure Flow field in UI fo...

How do you handle previews of screens with multiple view models?
I do much prefer screens with a single model emitting a single state.
But for complexity managment sake, sometimes some of my views have their own viewmodels.
For example, sometimes the main screen VM just tells the content whether a certain button is shown or not.
But this button internally has lots more logic to determine what state it is in, how it responds to actions etc. Hence it has its own viewmodel.
And similarly for lists. The screen VM emits simple models to indicate that there is...

API key Client side vs Server side

Ten tips to turn ideas into apps
Getting Real was one of the first business books I read and remains one of the most influential. It showed me a practical path to get from an idea to a tangible app. One chapter advises: out-teach your competition. That’s what the authors, Jason Fried and David Heinemeier Hansson, achieve through their books, podcasts and interviews. For over two decades, they’ve built and run Basecamp, a successful bootstrapped software company.

UI testing in Compose
I'm trying to figure out how to do automated app testing properly. It seems to me there is no way to test colors, backgrounds etc. other than in screenshot testing. This, however, is only in alpha and has major cons (change one color and all tests need to be updated). Am I getting it right? how do people test the way the app renders?...

Moto G8 Play Bricked
A few years ago I bought some Moto G Play 8th Gen (XT2015-2) devices.
Some of these devices were blocked by the store that sold them to me due to some problems we had with payments (delays). The store did not want to remove the locks and I refused to pay until they were unlocked as I had no guarantee that the stored data would be intact.
They are blocked to this day and I would like to remove this block somehow, even with some kind of "bruteforce".
I've already tried to reset one of the device...

Would you use a 'model-agnostic' AI plugin for Android Studio that matches Gemini’s features?
I’ve been using Gemini in android studio, but obviously other models are better at coding, debugging, everything. Lol. I was thinking of building a tool that’s model-agnostic, but with feature parity to Gemini, including gradle error support (i.e. the ask gemini button), unit test generation, UI debugging functionality, etc.
The idea is you can swap out Gemini for local models like Qwen2.5 coder or APIs like Claude, Open AI, etc. all within android studio. What do you guys think?...

Creating formula for probability of text cut within bounds

Should we stop using RealmDB in new projects?
So I was going to implement Realm DB for a new project but saw that they stopped support. Right now it doesn't even have support for kotlin versions above 1.21 other than trying to use community forks that aren't that reliable.
In comparison Room is harder and slower to implement but it has total support from Google.
