dependency...

Hey people! I’m trying out the new

CompanionDeviceService

(Android 12 DP2) while bonding with a Wifi (via SSID) and feel quite confident with my current setup. I get the following logs but my CompanionDeviceService is never called.

why navigation arguments of type Int, Long, Float are not nullable?

Does anyone know how to check if an environmental variables is empty in gradle ?? Ie APP_NAME I want to check if an empty string is sent back from the pipeline?

Greetings all! Is it possible that a

LiveData

with a backing property (MutableLiveData) inside the ViewModel to

Observe

and

Add

to an ArrayList can cause a race condition and a

Lock

is required? Provided that the ArrayList will get its value from a callback.

Hello folks, where is the android gradle plugin hosted? At first I thought it was available in maven central, but no. Then I though its gotta be on the gradlePluginPortal, but naaay. Anyone knows where? Tried google, but it also failed to resolve

How do I call a network api when the fragment destroy? If I write api call in ViewModel with

viewModelScope

, it would be clear when view destroy. Using

Globalscope

is a good idea?

Heyho, just trying out the new

addRepeatingJob

API for safely consuming Flows from ViewModel (thanks @Manuel Vivo !): https://medium.com/androiddevelopers/a-safer-way-to-collect-flows-from-android-uis-23080b1f8bda I am mostly observing multiple Flows from my ViewModel, e.g. one for the UI-State, and another one for One-Shot operations, like Toasts, Navigation, ... Would it be safe to consume them like this, with launching sub-coroutines inside

addRepeatingJob

? Or would it be better to have one

viewLifecycleOwner.addRepeatingJob(Lifecycle.State.STARTED)

-Block for each observation?

viewLifecycleOwner.addRepeatingJob(Lifecycle.State.STARTED) {
            launch {
                viewModel.uiState.collect { uiState ->
                    // configure UI here
                }
            }

            launch {
                viewModel.events.collect { event ->
                    // react to one-shot events
                }
            }
        }

Ok so I think the answer to this is yes but is it unsafe to have a

ViewModel

collect from a

Flow<T>

given to it by a

View

,

Activity

or

Fragment

? I.E.

// MyView.kt
val events: Flow<Event> = flowOf(Event1, Event2)

viewModel.handleEvents(events)

Hi All, I'm using StateFlow below is the code for the same. I'm facing an issue where the update in the StateFlow data is not triggering the updation of value at one place and it is working fine at the other place.

Hi all. Can anyone read fileuri and file path in android 11 using scoped storage

my app displays some images from the web. I need the app to have them downloaded so they can be displayed offline. I am already using Coil, how should I handle it? 1. Use Coil's backing OkHttp disk cache with no size limit and roll my own eviction policy 2. Use some other library (?) that handles this 3. Implement my own downloads (download images to a specific folder, handle all the records, eviction) 4. ???

Hi All, Is there any reliable Image picking lib which support android 11 and other use cases, It is super common task and almost 99 percent of stackOverflow answers are wrong. I hope at some point there will be an Android X lib for picking Images/Video/Documents @Ian Lake Please can you suggest reliable way to achieve it across different devices and Android Versions.

Hi guys! I’m having a strange behaviour with AS:

If I have a class that has it dependencies by field injection:

private val logger: Kermit by inject()

I cannot attach the debugger, any break point shows this icon: 🚫 (the gray one) If it’s constructor injection it attaches ok 🤔 I’m using Koin because this is a KMM project and the code is in the commonModule. Any ideia? Thanks.

Hello, All! Started android development with Compose framework and looking for good books about mobile UI/UX in general, any advice much appreciated!

Does this return a new map everytime it's read?

interface Foo {
    val bar: Map<String, String>
        get() = mapOf("1" to "1")
}

I would say yes but not sure

I am working on Jetpack Compose.

Hi! I am having trouble with the Android emulator. Not sure if this is the right place to ask this question, but maybe someone has run into the same issue before. So the problem is that Qemu produces massive disk-io ... ~400MiB/s or more and CPU is high as well. It starts when I launch an Android-Device in the emulator. Goes for some minutes and will then eventually stop. I am afraid this will destroy my SSD. Does anyone have an idea what could be the cause for this? Help is very much appreciated.

Hi, does Jetpack Compose for Android have compose "hooks"? IE I want to be notified of every (re)composition through my tree. Similar to Activity Lifecycle hooks.

Hey all, wondering if someone (perhaps @Ian Lake?) could help me out here... I cloned the Github androidx repo, and setup my local dev environment according to the Contribution guide at https://github.com/androidx/androidx/blob/androidx-main/CONTRIBUTING.md. Everything seems great so far. I can open and build the

navigation

project ... But when I run tests according to the guide (I've made zero changes. Just cloned the repo, open the project build, run tests), they fail...

cd navigation
# Run device side and host side tests
./gradlew test connectedCheck

.....

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':navigation:navigation-safe-args-gradle-plugin:test'.
> There were failing tests.

Am I doing something wrong?

Dear Community, I need your help! I have a ViewModel where I have 2 methods both are calling

suspend

methods and returning a

Double

result. How I can organise the code so

calculateResult()

method is called ONLY when

resultDoSomething1

and

resultDoSomething2

are received from the server. (without booleans)

val resultDoSomething1: Double = 0.0
val resultDoSomething2: Double = 0.0

fun doSowmthing1() {
    iewModelScope.launch {
        resultDoSomething1 = downloadDataFromServer1()
    }
}

fun doSowmthing2(){
    iewModelScope.launch {
        resultDoSomething2 = downloadDataFromServer2()
    }
}

fun calculateResult() {
     val res = resultDoSomething1 + resultDoSomething2
}
