Hi guys, did someone solved issue with kapt3 and databinding, that kapt3 shows compilation errors without info/error messages from databinding? Kotlin 1.3.72 + Android Gradle Plugin 4.0.0

[INFO] Processing java sources with annotation processors: [*redacted*]
C:\Users\arcao\project\app\build\generated\source\kapt\debug\com\example\app\DataBinderMapperImpl.java:131: error: cannot find symbol
import com.example.app.databinding.ViewListItemBindingImpl;
                                      ^
  symbol:   class ViewListItemBindingImpl
Note: [1] Wrote GeneratedAppGlideModule with: [com.bumptech.glide.integration.okhttp3.OkHttpLibraryGlideModule]
> Task :app:kaptDebugKotlin FAILED
  location: package com.example.app.databinding

and now i get this error:

error: [Dagger/MissingBinding] java.lang.String cannot be provided without an @Inject constructor or an @Provides-annotated method.

my class looks like this

class InstructorProfileState @Inject constructor(
    val instructorId: String
) {
    sealed class ViewCommand {
        class SetInstructorData(val instructor: Instructor) : ViewCommand()
    }

    val viewCommandStream = SingleLiveEvent<ViewCommand>()
}

Hello guys, I obfuscated my code to shrink it's size..etc using these lines

minifyEnabled true
shrinkResources true

inside build grade(module:app) I have a few data classes that I want to keep as is. what should I search for?

We are also going through Hilt transition as we speak if any one is interested https://github.com/toggl/android/pull/509/files We are still facing some issues but it should be ready to go soon. Hopefully we got the scoping and everything right.

How can I update the apk manually in Android codw Slack Conversation

How do I show progress when using coroutines? e.g. The code is usually written in the attached way. If I want to show progress, I can start before making the call. But I'm not sure how to end the progress. I ideally want to stop showing the progress when the coroutine ends, but I'm not aware of any such mechanism. I'll have to observe the different possible results that I get from the call and call

stopProgress()

in each of the observers. Is there a better way? 😞 Can I make this generic so I do not have to do this in each and every fragment?

This is making all my questions null once it goes to the question as the submit button was pressed in q1, i need it to nullify the options once the submit button has been pressed in each question and then un-nullify when going to the next question. Rather than just nullifying the options for all questions once submit has been pressed in one. I guess once it goes to the next question, they should be tv_option_(number of option).setOnClickListener(this) again. Can't seem to get it to work. For context making a quiz app, any help appreciated!

hello i'm trying to call the copy function by passing the

Hello guys, Leakcanary gives me the log as below. can someone please suggest me to resolve this.

I'm sorry about the possible off-topic, but I don't know where else to write. Explain why it is returning null, please

I have a keypair generated using the AndroidOpenSSL provider as follows:

// Get the EC key generator. Has to be the OpenSSL version
        val kpg: KeyPairGenerator = KeyPairGenerator.getInstance(
            "EC", "AndroidOpenSSL")

        val parameterSpec = ECGenParameterSpec("AndroidOpenSSL)"

        //initialize and generate the keypair
        kpg.initialize(parameterSpec)
        val kp = kpg.generateKeyPair()

I need to be able to store and retrieve this using the android keystore, however there doesn’t seem to be a way get the self signed certificate needed to store the key pair:

val certArray : Array<Certificate> = arrayOf(certificate)
            //var certPath = PublicKeyToX509Cert(keyPair.public)
            keyStore.setKeyEntry(alias, keyPair.private.encoded, certArray)

Basically the first certificate in the certArray needs to be the public key certificate. So the core question is how do I get from a publicKey to a certificate?

Is this correct behaviour for a RadioButton? It’s not centred within its view boundaries, so when we add a TextView next to it there’s too much space

Should inline classes work with Parcelize or is this a limitation? I have a Parcelable data class with an inline class id that I would like to send in a bundle...

Any good multi module projects for Android that feature well structured gradle files? Like a Library base module that handles the dependancies. I cannot for the life of me find anything

Hey, I am learning Android. I struggle to properly capture and react to the user's horizontal scrolling event across the screen. I'd like to touch the screen and with a horizontal scrolling motion I would like to update a number (TextView) on the screen, much like a traditional slider widget but the slider itself is the entire screen. I think I need to fiddle with

GestureDetector

like shown here. Can anyone link me some examples that I can learn from, please? I'm digging Google hard, but since I'm new, it's hard to ask the right questions.

Why does the following line not work:

this.mainLayout.removeCallbacks(this::stopConnecting)

But if the following does:

val stopConnectingRunnable = Runnable { this.stopConnecting() }
this.mainLayout.removeCallbacks(this.stopConnectingRunnable)

We thought (erroneously apparently and to much confusion/frustration) that the first would work.
