override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    val inflater = menuInflater
    super.onCreateOptionsMenu(menu)
    inflater.inflate(R.menu.main_menu, menu)

    val manager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
    val searchItem = menu?.findItem(R.id.search)
    val searchView = searchItem?.actionView as SearchView
    searchView.setSearchableInfo(manager.getSearchableInfo(componentName))
    searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(query: String?): Boolean {
            searchView.clearFocus()
            searchView.setQuery("", false)
            searchItem.collapseActionView()
            Toast.makeText(this@MainActivity, "looking for $query", Toast.LENGTH_LONG).show()
            return true
        }

i have this in the main activity. if I want to reuse this(it's a search bar on the actionbar) in another activity, do i have to copy and paste the code every time? or is there an easier/efficient way to do this?

hey anyone know if there's a way to get a DialogFragment (Bottom sheet DialogFragment) to be the root of a modal flow? Meaning I don't want it to be dismissed when I navigate from it to another fragment

I'm wondering how to dependency inject into a feature module. All of the examples I see uses an activity. Is it not possible to use a feature module without a separate activity? From what I've seen you can just navigate by single-activity navigation and specify which module a certain navigation action goes to. I can't figure out how to get dagger working though. This is in one of my modules.

@Singleton
@Component(
    dependencies = [AppComponent::class],
    modules = [
        ViewModelModule::class,
        FragmentModule::class
    ]
)
interface StartupComponent : AndroidInjector<BaseApplication> {
    fun inject(activity: MainActivity)
}

But I have nowhere to initialize this component from. This is the error that I get:

No injector factory bound for Class<ferm.jonny.startup.presentation.fragments.ExtendedSplashScreenFragment>

Hi everyone 👋 I'm trying to make my app hit my server which consists of the FCM api endpoint, every weekly or monthly based on the user preference, but I don't really know how to go about it, I figured the operation would be a background task but I'm stuck at what I need to use cos AlarmManager would only achieve it for an exact time hour you fixed. So anyone with any article or guide would really appreciate

Anyone encountered UI with Grouped recyclerview and the section items are single option? Could find any helpful resource. If you know something hit me up. Thanks!

Hello, im having an issue with Kotlin Flow and Room. Im trying to return a Flow of a Tupple data class(https://developer.android.com/training/data-storage/room/accessing-data#query-subset-cols). But the compiler throw this error:

Has someone experienced something like this?

Hello, I’ve been trying to move common details of my android lib modules to a specific plugin defined in

buildSrc

. Using Kotlin along with the

kotlin-dsl

for gradle i’ve been able to move pretty much everything except for the following excerpt:

android {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

The

kotlinOptions

isn’t visible from the extensions within

buildSrc

sourceset, probably because I don’t implement the dsl? I’ve tried doing the following, but it didn’t work

target.tasks.withType(KotlinCompile::class.java).forEach { task ->
    task.kotlinOptions.jvmTarget = "1.8"
}

I have a question related to passing touch event from a dialog fragment to the activity below (parent activity). My goal is to be able to have the dialog showing but allow the transparent section of the dialog to pass touch events back to the parent activity so that other things like clicks/ keyboard input can still happen as the dialog is being shown. Currently i am using

dialog?.window?.decorView?.setOnTouchListener { view, motionEvent ->
    activity?.dispatchTouchEvent(motionEvent)
    false
}

to try to dispatch the touch event to the activity but it doesn’t work as i expected. Does anyone have an idea of how to approach this?

Anybody know how to show an empty state view if PagingData has empty items? I can't seem to check the size of the items in PagingData

anyone know if theres a way to pass args into the constructor of a fragment using the navigation component? I have a VehicleFragment that should take a vin. I know I can pass it in via a bundle but was wondering if constructor args are possible with the nav component

Embarrassing I don't know this, but if I want to use the newly stable Kotlin 1.4.0 explicit API mode with Android build.gradle, where would I put the block?

kotlin.explicitApi()

Is `await`ing in fragment A for a computation done in another fragment B possible in anyway? I know this is a dumb question, but I'm finding it hard to chain a sequence of asynchronous operations.

Does AGP 4.0 and 4.1 supports Kotlin 1.4?

I have this bug I updated my old project which I used Kotlin DSL last year I was using Android studio 3.5 at that time I have changed gradle all versions to recent once even kotlin version 1.3.7* I can't pass this error if anyone encountered help me out kindly Forgot to say it has dynamic modules in it

Any reason why

emit

says it has to be ran from a coroutine body ( I am well aware it is a suspend function)?

import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.flow

class FirebaseDataSource (private val firebaseFirestore: FirebaseFirestore) : NetworkDataSource{

    fun fetchMenuItems(): Flow<Food> = flow{
        firebaseFirestore.collection("menu_items")
                .get()
                .addOnSuccessListener { documents ->
                    try {
                        for (document in documents) {
                            val doc =...
                            emit(doc) //error here
                        }
                    } 
                }
    }

In every example I've seen online they have it just inside the

flow {}

Eg.

fun simple(): Flow<Int> = flow { 
    for (i in 1..3) {
        delay(100)          
        println("Emitting $i")
        emit(i)
    }
}

any one know why when using registerForActivityResult in BottomSheetDialogFragment the ide say Unresolved reference: registerForActivityResult error but it runs fine

Hey! Got a problem and I cant think of an elegant and clean solution. Basically in a mutli feature (module) project I have a restaurant Menu feature and an Order feature to preview and confirm the selected items. The problem lies in notifying the Feature Order about adding a new item while keeping them decoupled as much as possible. You select an item from the Menu and it should give a notice or something to the Order module. Single activity, bottom nav bar so cannot use the fragment arguments. Modules are VMs,Fragments and their data layers.

Good day to all! 🙂 My name is Eugene and I'm a product manager at JetBrains. Currently, I look for Java developers who continue to use Java in their production projects. I'd like to learn more about your UCs and why's do you use Java instead of Kotlin. I think most of you have completely switched to Kotlin, but perhaps you know people out of this channel who continue to use Java 🤔 Just DM me and I'll ask a few questions :android: That's it. Have a nice day and happy coding 👩‍💻

class AppViewModel : ViewModel(), LifecycleObserver {

    val myCoreModel = MyCoreViewModel()

    @OnLifecycleEvent(Lifecycle.Event.ON_START)
    fun onStart() {
        myCoreModel.appEnteredForeground()
    }

    override fun onCleared() {
        super.onCleared()
        myCoreModel.appWillClose()
    }

}

How can I capture, from within the Android’s ViewModel, the event of the app entering the foreground? I tried this way, but my function

appEnteredForeground

doesn’t get fired.

When launching a share intent, is it possible to know when it is complete? I want to move on after the user has seen the share dialog, but not until it has been dismissed

Am I missing something or is the kotlin 1.4.0 plugin for android studio not released on the stable track yet?

After 1.4 update our build started failing with

Caused by: java.lang.IllegalStateException: Unexpected non-class file: META-INF/versions/9/kotlin/reflect/jvm/internal/impl/serialization/deserialization/builtins/BuiltInsResourceLoader.class

Any ideas people what could be the cause?

what is the best way to get Object returned from a CoroutineWorker • sth like Result.Success(object)

what is the correct way to use viewBinding in coustom view mainly extending ConstraintLayout or should i avoid it and use findViewById?

How do I setup a count-up timer that runs even if app is killed?
