Timeout in a coroutine, Kotlin I am working in Kotlin to create a UDP socket between an Android client and a server. For receiving messages, I'm using a coroutine, and the code itself works correctly, checking for every incoming message. My objective now is to set a timeout (or something similar) of 30 seconds to detect if the communication has been lost. If the timeout is reached, I do NOT want the loop to block; I want it to continue to receive any incoming messages. I just want to log or display an appropriate message...

Kotlin Multiplatform "actual" declaration in "commonTest" module not working: "no corresponding expected declaration" In my Kotlin Multiplatform project I have an expect class declared in "commonMain" module, with specific actual implementations in the "androidMain" and "iosMain". Problem is I am writing unit tests in for some shared code that should be in "commonTest" module. My expect class is a dependency of the class being tested, therefore I need to mock it since I don't really have an implementation defined yet (since the test shouldn't depend on the platform). So what I want to do is define a third...

Access generated 'R' or 'R.drawable` object in Android What I’m trying to do: On our project we reference UI libraries from 3rd parties (delivered via maven/aar) and one of those libraries has a bunch of vector drawables we should use.

How to R8 de-obfuscate a library you own? Introduction: I have deployed an Android Library to Maven Central. I see Maven is providing this artefact correctly but, perfectly readable. I'm trying to obfuscate the code to avoid this behaviour as we don't want that behaviour, we want to keep our library closed-source by the moment. Problem: I have configured Gradle to obfuscate the library enabling the Minify and setting some Proguard rules for the data classes. I guess if I deploy this library to Maven, will now be obfuscated thus...
