Hello People 🖐️🏻 Need help, anyone here works on new Android Slices, I want to ask about something

Is there any similar blog/concept on Android as- https://medium.com/@stasost/ios-root-controller-navigation-3625eedbbff

Hello Guys, I'm using Android Architecture Components Room in my project and I have an

Entity

with a

Enum

class as a property. It's something like this:

@Entity(tableName = "tb_episode")
data class Episode (

    var title: String,
    
    var episodeType: EpisodeType
    ...
)

And I have the

TypeConverter

for it:

object Converters {

    @TypeConverter
    @JvmStatic
    fun toEnum(code: Int): EpisodeType {
        return when (code) {
            1 -> EpisodeType.PODCAST
            2 -> EpisodeType.ALBUM_REVIEW
            else -> EpisodeType.DEFAULT
        }
    }

    @TypeConverter
    @JvmStatic
    fun fromEnum(type: EpisodeType): Int {
        return when (type) {
            EpisodeType.PODCAST -> 1
            EpisodeType.ALBUM_REVIEW -> 2
            else -> 0
        }
    }
}

Also, I added the

TypeConverters

Annotation to my Database class:

@TypeConverters(Converters::class)
abstract class AppDatabase : RoomDatabase()

But when I try to run the App I get this message:

Class is referenced as a converter but it does not have any converter methods.

I don't know if Room doesn't support Kotlin

Enum

class or if I'm doing something wrong. Anyone can help me with this?

I’ve noticed that FragmentActivity.activity can be null, in what situation could this occur? Can the activity be destroyed without the destruction of the fragment?

Can anyone help me:

This message was deleted.

What's name of this? Why I couldn't put Toast in it?

@gildor Thanks for the link ! My problem is that I don't really understand coroutines, I guess! 😄 I was setting up a simple app to update some values by making API calls in HTTP. I managed to communicate through the socket using coroutines, but as soon as I was trying to update the UI through callbacks, it became messy. That's why I thought of just creating one other thread for the network and not use coroutines. But I felt I was just going at it the wrong way, so that UI looks perfect to me! Thanks again 😉

My team doesn't want dependencies. 😞 Would using OkHttp (which HttpUrlConnection implements anyway) change anything? Because I might be able to sell that.

Fwiw, Android internally uses okhttp. https://android.googlesource.com/platform/external/okhttp/

if i were to add DI to an already established project, is it worth considering Koin at this point, or is Dagger 2 still the suggested route?

https://github.com/Nilhcem/i2cfun-androidthings/blob/master/app/src/main/java/com/nilhcem/androidthings/i2cfun/device/components/ArduinoFanI2C.kt Hi, What modifications would I have to make in the code above, to make the result of this line: companion object { fun fromValue (i2cValue: Int) = Speed.values (). firstOrNull {it.i2cValue == i2cValue}?: MEDIUM which in the case is static (MEDIUM) in dynamic, ie, I want to get this value from a firebase field

Why does studio autofill generates a nullable bundle for onRestoreInstanceState?

override fun onRestoreInstanceState(savedInstanceState: Bundle?) {
        super.onRestoreInstanceState(savedInstanceState)
    }

I am reading some code from developer in github. setOnKeyListener(View.OnKeyListener { v, keyCode, event -> if ((event?.action == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) { action(text.toString()) return@OnKeyListener true I dont know the purpose of line : return@OnKeyListener true

Does anyone knows what would be returned in case there is no data in database

Hi guys, anyone has problem with Dagger component builder @BindInstance and kotlin inline classes

I will pay $ to anyone who can help solve my issue tonight 😉

Running into an interesting issue with a

BroadcastReceiver

when trying to set a permission. So I set the permission in the sending app in the manifest using

<uses-permission.... />

and then include that permission in the

sendBroadcast(intent, permission)

call. And in the receiving app I have the permission set in the manifest where I am declaring the receiver. But my

BroadcastReceiver

won't accept the broadcast. The interesting thing is that as soon as I remove the permission from both apps, my broadcast works perfectly. Any ideas? Edit: Fixed. It was due to the app signature.

any idea why my proguard is failing here? https://pastebin.com/itxRfUKx here’s my .pro file https://pastebin.com/56EDACgH

Please, How do i force a function to use its default... priorityFilter is null i want it to use the default value

I want to implement reactive UI framework based on Anko with syntax like this. But I get error

Unsupported reference to synthetic extension property for a Java get/set method

. Is there way to fix it without creating extension property for each get/set? Or may be any ideas about another clear syntax to bind view property with reactive property?

Hello, you need to run the ContactsDetail NavigationDrawer activity from the MenuMain NavigationDrawer.I write a bug. How to fix it? Thank you https://hastebin.com/xanowezila.cpp

Hi All, i am converting kotlin code to java and stuck on some function can someone please help me on below code https://paste.ofcode.org/3asiRwyrz4343W3UE8jZm2Z Main: line 21 to 29 thanks in advance

how do you do a check for a

lateinit var

to know when its been initialized

im asking because i have seen some crashes with it, and i dont think its being maintained anymore

Is the application context only garbage collected when the application is destroyed, or is there any other scenarios where it might happen? Trying to understand why when creating singletons / kotlin objects it seems normal to pass in the context every time. Could you not just initialise it with the context one then call getInstance() or whatever without having to pass in the context? The object would be initialised in the Application class of course

e.g. Google pass in the context to every getInstance() call here https://github.com/googlesamples/android-architecture-components/blob/master/BasicRxJavaSampleKotlin/app/src/main/java/com/example/android/observability/persistence/UsersDatabase.kt
