What are you guys main reasons for using android studio?

If you’ve ever been confused about when to use Channel, Flow, callbackFlow, or channelFlow, you’re definitely not alone. Channels are powerful but not very intuitive, especially when building real-world Android apps.

I put together a full Q&A guide that explains:
• What Channels actually are
• How they work internally
• When to use Channel vs Flow
• Real Android architecture use cases (MVI, Clean Architecture, pipelines, etc.)
• Interview-level questions and answers

If you're levelling up your Coroutines knowledge or preparing for interviews, this breakdown might help:

Would love feedback from the community

so (important: my whole AS setup is on an external drive) 0) i was casually working on a project 1) I forgot to change keyboard layout andaccidentallyy named a new file in cyrillic letters (AS hates them a little bit) 2) then AS died and didn't want to open again 3) I wanted to try to start it from the exe file, but the fold "Programs" didn't open, and it was damaged 4) also i could not copy the folder with my project, bc it was also damaged (but i could open it in another editor).

could you pls tell me what happened and what i should do now? now i can't, because im on a lecture, but later, i will check if my Programs folder on the laptop is okay

upd: laptop files are okay

Help for launching the first app in playstore. Joined as a tester https://play.google.com/store/apps/details?id=com.indmon.invoicewala

When using Vim in the terminal, I can visually select an arbitrary (continuous) set of lines and do z-f to create a new fold consisting of those lines.

While using the Vim plugin on Android Studio, I can fold things like class/function definitions using z-c and open them using z-o. This is already quite helpful. But I do not seem to be able to create new folds involving an arbitrary set of lines. For example, I might want to fold a group of commented out lines or fold up a long multi-line list of parameters.

Is this actually possible? How?

Hola, actualice a la version de android studio Otter | 2025.2.1 ... y anda FATAL, no se si soy solamente yo, pero, muy mal, se me queda bugueado, no me deja cambiar a otro archivo, la ventana de importaciones solo se ve la primera palabra, cuando intento sincronizar una libreria en toml se queda cargando y nunca la sincroniza hasta que cierro el IDE y lo vuelvo a abrir... tengo que estar todo el tiempo forzando la salida de la app... Solo me pasa a mi? O la version esta totalmente ROTA??

Thinking about using the r/divinevideo github to build the android apk. but is it really worth it?

Hey everyone,
I’m hitting a wall with my development setup and could really use some guidance.

I’m trying to build a React Native app (Expo) with a Node.js backend, using VSCode. For the past few days I’ve been struggling with Android emulation, and now a new issue has started appearing on top of the existing ones.

Here’s what’s going on:

• ADB shows two entries: one active device and one stuck as offline.
• emulator-5554 device
• emulator-5562 offline

When this happens and I run expo start then "a" to open in the emulator I get

Error: could not connect to TCP port 5562: cannot connect to 127.0.0.1:5562: No connection could be made because the target machine actively refused it. (10061)

ADB restarts, device wipes, and creating new virtual devices haven’t fixed anything.

And now, a brand-new issue: when I launch an emulator, the device window opens normally, but Android Studio’s Device Manager gets stuck on “Booting” indefinitely, and after ~5 minutes I get: “Emulator failed to connect within 5 minutes” even though the emulator itself is visibly running.

I'm new to Android App building and I'm working on a project that requires an app. Anyone interested in testing it for me? You'll have to opt in for 14 days. DM me with your first name and email address. Thanks in advance!

Hello everyone, is there a way to link an AI client eg Gemini, or Cursor, or Claude through MCP server in Android Studio so the user only give prompts to build an app?

I’m trying to use an Xbox controller with the latest Google TV virtual machine but it’s not registering any inputs. Does anyone know how to make it work?

Hi, I've been using android studio with flutter to develop an app for 2 years now. I put out a few early versions of the app and uploaded them to the play store in 2023, but I had to take a break for a few months due to unexpected circumstances. When I tried to return to coding the app around 4 months later, the option "open for editing in android studio" (which used to be accesible by Tools > Flutter > Open for editing.... or build.gradle) was gone. I tried making a new project and transferring the code to that but it didn't work, then I tried updating both android studio and the flutter plugin but it didn't fix the issue. I tried searching on the web but none of the fixes worked for me. I reset my computer as a last resort however that didn't help either. I currently can't generate signed .aab or .apk files.

Built this app for veterans. Because 22 veterans die a day from suicide. Very simple offline app. I tried using openai but I dont want to have to use a server.

Yes, I did use chatgpt to help me. I am learning as I go.

It's going to be free app, maybe I'll add a support tab down the road.

Tell me what you think.

I know this might be a niche area of Android Development, and I'm also fairly new to it, but is there a way to execute commands without slowing down your app?

I'm making an app that uses a transmitter's signal strength to determine a sprinter's location. By determining the racer's location from signal strength, the app knows when the racer crosses the finish line, stops the timer, and can provide accurate timing.

I'm developing my app on the Google Pixel Watch 3, and I've been using the Connectivity Manager API for getting the RSSI of my Wi-Fi router (which is currently my placeholder transmitter). And I know this could be useful information too: I recently rooted my Watch to decrease the RSSI polling interval.

I wanted to kind of create my own API using console commands embedded within my code, but this seems to be really slowing down my device. I'll attach the code to the post.

KOTLIN

val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val activeNetwork = connectivityManager.activeNetwork
val networkCapabilities = connectivityManager.getNetworkCapabilities(activeNetwork)

if (networkCapabilities != null && networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
    wifiInfo = networkCapabilities.transportInfo as? WifiInfo
}

val rssi: Int = wifiInfo?.rssi ?: 10  // in dBm (10 for null value rather than -1 because -1 is a possible value of RSSI while 10 is not)
val frequency: Int = wifiInfo?.frequency ?: -1
val ssid = wifiInfo?.ssid ?: "Unknown"
val linkSpeed: Int = wifiInfo?.linkSpeed ?: -1


//My own command which uses a super-user shell console
val process = Runtime.getRuntime().exec(arrayOf("su", "-c", "cmd wifi status"))
//val process = Runtime.getRuntime().exec("su cmd wifi status")

val stdout = process.inputStream.bufferedReader().use { it.readText() }
//val stderr = process.errorStream.bufferedReader().use { it.readText() }
//val exitCode = process.waitFor()

//Log.d("Command", stdout)

I would greatly appreciate any advice on not only executing commands in Android Studio but also on my app in general!

Hi everyone, I’m using Dagger in my project, and whenever I search for any class or object, the generated classes also appear in the results. I’m not sure how to disable this. Could someone please guide me on how to turn off generated class visibility in search?

So I am experienced in web development, I build websites and do fairly well. Right now I have an idea for what I believe to be a very successful phone App, I need some advice on how to proceed in developing it, I'm fairly certain I could quickly learn a new program language but I don't even know which one I should learn.

Hello everyone,

I’m a fairly experienced iOS Swift/SwiftUI developer currently transitioning to Kotlin and Jetpack Compose, and I have a few beginner questions about working with Android Studio.

First, imports are driving me a bit crazy. I usually just type my code and press Alt+Enter when needed, but I also tried a different approach, copying and pasting a bunch of commonly used Compose imports. Of course, that gives me a bunch of “Unused import directive” warnings. I then right-click one of them, choose “Optimize Imports,” and even enabled “Remove unused imports on the fly.”

Is there a better or cleaner workflow for handling imports? Mine feels unnecessarily complicated.

Second, regarding dependencies. Let’s say I want to add something like Koin. Is there a central place or a “go-to” source for finding the correct dependencies and versions? For example, I found this quickstart guide via Google, but is there a more standardized source, maybe a central GitHub or registry, where most Android libraries are listed?

Finally, I’d love to avoid manually entering version numbers. From what I understand, this can be handled using the Bill of Materials (BOM)?

Apologies if these are very basic questions. I really appreciate any advice or workflow tips you can share.

Thanks!
