Android: Start to collect from Flow when button pressed? I am trying to build a sign up and login screen with Firebase Authentication. When a user enters an email and password, they can click a sign up or login button which subsequently makes a network request to Firebase to perform the respective action. Now, the network request returns a Flow which looks like this for the login action and similarly for the sign up action: fun authenticate(email: String, password: String): Flow = flow { emit(NetworkResponse.Loading) try {...

Placing New Marker on Google Map - Function not being called on API 33 but works fine on API 31 I'm a beginner in android development and kotlin so pardon me if i ask anything too basic. I'm working with google maps, and i'm trying to set a new marker for a location input by the user. This is done by my method updateLocationOnMap(location: String, address: Address). updateLocationOnMap removes the previous Marker from the map and places the new one via placeMarkerOnMap. Everything works fine on a device running on API 31, but not for API 33, where placeMarkerOnMap does not even get...

Mapping a soap client exception defined in wsdl to a custom one by using interceptors I've been using an apache CXF client to communicate with an external SOAP service, which returns faults. My application uses hexagonal architecture, so I would like the soap module to throw domain exceptions. I wrote the interceptor code, that triggers after the exception is mapped to the exception defined in WSDL, and maps it to my own, then sets the message's content to it, because it seemed like a better approach than breaking the interceptor chain by throwing it right there. I guess my...

How to get annotations of a variable in external method using Kotlin? I'm starting with Kotlin reflection. I need to write a method in Kotlin that would take a variable (in this case lets say of type String) and return all annotations (if any) that are applied to that variable. fun getAnnotations(variable: String): List{ //get annotations here } Of course that is only possible if annotations are also passed to the method along with variable itself. I wasn't able to find that info in documentation. For my use case, it is not acceptable to send entire user...

Spring Authorization Server JWT authentication Having JWT authentication of users (Resource Owners) in Authorization Server makes it impossible to use /oauth2/authorize endpoint. I've debugged it a bit and found a OAuth2AuthorizationEndpointFilter is set up before the BearerTokenAuthenticationFilter. So the OAuth2AuthorizationEndpointFilter checks whether the request is authenticated but the authentication is not set by BearerTokenAuthenticationFilter yet. What configuration changes should I apply to make it all work? Can I somehow set...

Jetpack Compose - State value change is not being notified in @Composable I'm newbie in Jetpack Compose. I'm working on a project now and I've come across a strange problem. I have a StateFlow in the ViewModel which I'm observing in the @Composable using collectAsState(). StateFlow carries marker information, these markers need to be shown on Mapbox map.

Kotlin with Composer: why are all project files in the presentation package? I'm started to learn Kotlin + Composer for Android (specially WearOS) development. What is really strange for me (coming from C++ and Java world), is how the projects are built up architectural. I found quite a lot samples, but all of them seems having one thing in common: their packages are always inside the presentation package what Android Studio creates for you with your first "Empty Composer Activity": <a...

(Kotlin - Android Studio) - Set Metronome Timer to play a sound precisely at every given interval (e.g.: 500 ms) I'm making an Metronome app. I wish to have it count precisely 4 beats in a loop with an accent on the first beat. Inside Android Studio on my simulator it works fine, but on my actual phone (Galaxy J3 - 2018, Android v9) that time interval is not stable at all it's very random. I have tried Threads, Coroutines, Handlers but nothing seems to work. I also had a look at the Timer objects, I was trying to copy someone's code on <a...

Android deeplinking with navigation component I am working on single activity app with navigation component.

Sort array according values from another array I have two arrays .First array (points) is arrayOf(22, 8, 17, 13, 20) and second is an empty array. How can I set the rating to second array, according points in the first array. E.g. largest value is 22, so first element in the second array will have value 1. Second the largest value in the first array is 20, so last element in the second array will have value 2. At the end second array will look next (1, 5, 3, 4, 2). What's the best way to implement this?

Ensure all Jar files that are run, are signed, and are signed by me? I have a Java Desktop application. I'm trying to find a way to download updated jars, and run them without my users having to completely re-install their application. I need to do this safely, and want to verify that 1. the Jars I run haven't been modified, and 2. the Jars I run were signed by me. Because of how MSIX works, and the new standards for mac os applications, I either can't, or am not supposed to modify my application directories, meaning that I have to save my new jars in an...

Kotlin delay won't fire on long delays So I have 2 main places I have that I use a delay. Both are designed as loops, the first is a 5 second delay, and the second is an hour. They are along the lines of this: GlobalScope.launch { delay(5000) // Execute code } This code runs in the background, doesn't matter if the app is open or closed or if the phone is locked. The 5 second delay like here works fine, however, the 1hr one doesn't seem to work (I had it set at 60 seconds to test and it worked fine, just updated the...
