Yo guys you should try this plugin for exception handling. v1.0.3 under review for 1-2 days atm. https://github.com/ogzkesk/ExceptionGuard-Kotlin-Plugin

Hi, is jodatime still relevant for modern android applications written in Kotlin?

Hi! When I change the app language, the screen somehow blacks out or flashes. How can I fix this? I’ve tried numerous solutions, but none of them worked. Only the language screen is built with Compose; the others use XML

private fun applyAppLocale(languageCode: String) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        // Android 13+: Use LocaleManager for per-app persistence
        val localeManager = context.getSystemService(LocaleManager::class.java)
        localeManager.applicationLocales = LocaleList.forLanguageTags(languageCode)
    } else {
        // Pre-Android 13: Use AppCompatDelegate
        val locales = LocaleListCompat.forLanguageTags(languageCode)
        AppCompatDelegate.setApplicationLocales(locales)
    }

    // Immediate update for resources (affects View-based UI)
    val config = Configuration(context.resources.configuration)
    config.setLocale(Locale(languageCode))
    @Suppress("DEPRECATION")
    context.resources.updateConfiguration(config, context.resources.displayMetrics)
}

Hi Android community 👋 I'm the developer of Immutable Arrays for Kotlin and I'm hoping to bump the minimum version to JDK 17 in order to upgrade dependencies. Can Android developers safely use Kotlin libraries that use inline classes & inline functions with Java 17 bytecode and still target older devices? I want to make sure I'm not excluding a large portion of the user-base but I'm not familiar with Android development. Thanks in advance 🙏 p.s. The next release will reduce temporary memory consumption of some operations by 16X on average. Almost done benchmarking locally before pushing.

👉 Hello fellow Devs I finally had a chance to upgrade my most popular Android open-source project This is still the most complete Android sample you can find around (Kotlin, Coroutines, Jetpack Compose, Jetpack Navigation, Material Design 3, Clean Architecture, Tests, Feature Modules, MVVM, Static Analysis, CI Config, Gradle Convention Plugins, and more). If you spot something off or areas for improvement, please let me know! https://github.com/igorwojda/android-showcase

Hi. Is there a slack channel to ask questions related to Android & Google Play Billing Library?

👋 Hello, team!

I have an issue with new Android 16 behaviour change of ignoring activity orientation specified in manifest. Even having

appCategory="game"

in manifest and the activity forced to "landscape", the OS rotates the screen, displaying the game in portrait but simulating a fake landscape mode, with two black spaces on top and bottom of the game screen. But the main issue is that is destroying and recreating my activity. That breaks completly the game. How is supposed we should sholve this? Some games are old games developed a lot of years ago, even in java, and are not prepared to survive activity recreation. Supposedly

appCategory="game"

should help us keeping our games alive in Android 16, but that onDestroy and onCreate doesn't help.

Hi, I have a problem with Android Studio (version arwhal 4 Feature Drop | 2025.1.4) and kotlin versions: The IDE does not recognize the correct kotlin language version I am using (2.2.20). The features I use (e.g. Clock Interface) work fine when building, but the IDE shows an error saying "This declaration is only available in Kotlin 2.1 ...". Now when I try to change the language version in the settings, it does not work, it still shows the same error and when restarting IDE it jumps back to 2.0, even though in my gradle i definitely have 2.2.20 configured. This is my gradle:

agp = "8.13.0"
kotlin = "2.2.20"

[plugins]
androidApplication = { id = "com.android.application", version.ref = "agp" }
kotlinMultiplatform = { id = "org.jetbrains.kotlin.multiplatform", version.ref = "kotlin" }

plugins {
    alias(libs.plugins.kotlinMultiplatform)
    alias(libs.plugins.androidApplication)
...
}

kotlin {
    sourceSets.all {
        languageSettings {
            optIn("kotlin.uuid.ExperimentalUuidApi")
        }
    }

    androidTarget {
        compilerOptions {
            jvmTarget.set(JvmTarget.JVM_21)
        }
    }
...
}

And in the settings it looks like this:

Hey everyone! The author of this post is trying to point out some issues with Kotlin's

Any new schedules Junie release for Android Studio Otter ?

hello. i am trying to use the ktor lib in order to perform some cloud requests. if i have a vpn connection ON on the device, the requests get timeout (even if the timeout is set to 30 seconds). i will leave in the thread how chatGPT suggested to configure the HttpClient I use in order to avoid the problem, but I still encounter it has anyone encountered this issue?

Hi just like to ask about the TimePicker composable, is there a way to update it's semantics / talkback? currently when I'm using clearAndMergeSemantics it removes the focus on the whole timepicker and just become one ( the dial and the input ), are there other ways to update it's semantics? specifically for the dial and for the input texts separately?

Hi everyone 👋 I’m working with Room in an Android app. • In debug builds, Room works perfectly without any special configuration. • But in release builds, Room breaks unless I add ProGuard/R8

-keep

rules for my

@Entity

models, DAO interfaces, and sometimes even fields. My concern is: If I keep these classes, their names and structure are no longer obfuscated in release builds. Doesn’t this expose the database schema to reverse-engineering? How do people handle this securely? Any guidance or best practices would be really helpful!

Hi i am trying to record audio and STT(Speech to Text) at the same time? I'm using MediaRecorder for recording, but not sure what to use for transcription. Tried Android’s SpeechRecognizer, but it can’t run together with MediaRecorder because both need the mic. is there any other way I can achieve this?

Can anyone help me, about instrumented tests in release build with R8 Enabled, in recent AGP?

Hi, any ideas why local notifications are often not showing up (at all)? • scheduled daily at ~9:00am • cancelled and re-scheduled often (on app's on resume): this is temporary behavior which I'll improve, but technically, it should work? I added remote logging and noticed that the broadcast receiver is not called (though it's also technically possible that the error reporter is not available/doesn't work) Thanks!

Hi everyone. We’ll appreciate your feedback.

👋 Hello, team!

👋 Hello, team!

I'm using a hidden api jar, I switched from kotlin 2.0 to 2.2, and now it doesn't seem to find the references anymore - via

compileOnly(files("../hidden-apis/android-30-custom/android.jar"))

, but that doesn't seem to be pulling it in correctly. I've got some code which compiles fine with kotlin 2.0, but not anymore with 2.2. They always showed up as missing references in the IDE, but gradle was fine with them.

Hi everyone 👋 I have an API that returns a list of 2000+ items in one response. Right now the UI is not laggy, but I’m worried it might lag on older or low-end devices. I’m using Jetpack Compose + MVVM and I’d like to add paging, but the server does not support pagination. What’s the best way to handle this? • Keep everything in memory and page it locally? • Save the data to Room and use a

PagingSource

?

Hi everyone, I need some guidance regarding Android app startup performance. I’m working on a large production app (~6 million users) and currently facing slow startup time. Current setup: • In the Application.onCreate() we initialize multiple SDKs (Firebase, payment SDKs, Facebook, etc.). • In the Splash Activity, I do some initial checks to decide the next screen and also make an API call to fetch required data. Because of this, the app startup time has increased. Startup metrics (Macrobenchmark): timeToInitialDisplayMs min: 1283 ms median: 1305 ms max: 1542 ms Device: Pixel 3a (Android 12) My questions: • What are the best practices for initializing multiple SDKs without impacting startup time? • Should SDK initialization be lazy / deferred, and if yes, how do you usually decide what to defer? • Is it okay to make network calls in Splash, or should this be moved elsewhere? • What approach do you personally prefer in large-scale apps? I’d really appreciate any suggestions, patterns, or real-world experiences you can share. Thanks in advance!
