Android studio build error in navigation component, action is not abstract and does not implement abstract member actionID

Question

Out of nowhere, the build is crashing with a strange error related to the navigation component even though it used to work before, the error is in the generated class, in my case NativeLanguageSelectionFragmentDirections

Here is the error

e: C:\Users\David\StudioProjects\android\app\build\generated\source\navigation-args\debug\com\linguistic\linguistic\framework\presentation\loginscreens\ui\main\NativeLanguageSelectionFragmentDirections.kt: (10, 16): Class 'GoToSelectLearningLangAction' is not abstract and does not implement abstract member public abstract val actionId: Int defined in androidx.navigation.NavDirections
e: C:\Users\David\StudioProjects\android\app\build\generated\source\navigation-args\debug\com\linguistic\linguistic\framework\presentation\loginscreens\ui\main\NativeLanguageSelectionFragmentDirections.kt: (13, 12): 'getActionId' overrides nothing

And here is the code of the navigation graph

<?xml version="1.0" encoding="utf-8"?>

        tools:layout="@layout/fragment_welcome" />
</navigation>

I am using

 "androidx.navigation:navigation-fragment-ktx:2.3.5"
 "androidx.navigation:navigation-ui-ktx:2.3.5"

Gillespie

did u try invalidating cache and restart? – Misread

Yes, for sure, I tried another android Studio version xD – Gillespie

That sounds like this issue, but that issue only affects Navigation 2.4.0-alpha01. Are you sure you aren't using Navigation 2.4.0-alpha01? – Nerissanerita

yes I am using navigation androidx.navigation:navigation-compose:2.4.0-alpha01 for compose since part of the project is written in android compose – Gillespie

even after downgrading the dependency mentioned in my previous comment to androidx.navigation:navigation-compose:1.0.0-alpha10, I am still facing the same issue – Gillespie

Answer 1

I had this problem too. Until they release the fix. Please try this:

plugins {
  id("androidx.navigation.safeargs")
}

instead of

plugins {
  id("androidx.navigation.safeargs.kotlin")
}

Finisterre

This was a quick way of working around the same issue for me, thanks. Are there any drawbacks of using the non-Kotlin version? – Incomprehensive

You can't use named arguments for example. – Publisher

What is the cause of this problem?... What is the difference between these two plugins – Crapshooter

@Venkataramanan, to generate Java language code suitable for Java or mixed Java and Kotlin modules use androidx.navigation.safeargs, to generate Kotlin code suitable for Kotlin-only modules use androidx.navigation.safeargs.kotlin, from here – Epigeal

Three years later still valid. – Tamarau

Answer 2

As for my case, I had to update Safe Arg plugin as well to get rid of the error message.

[build.gradle]
buildscript {
    ...
    dependencies {
        ...
        classpath 'androidx.navigation:navigation-safe-args-gradle-plugin:2.4.0-alpha04'
}

[app/build.gradle]
dependencies {
    ...
    implementation 'androidx.fragment:fragment-ktx:1.4.0-alpha04'
    api 'androidx.navigation:navigation-fragment-ktx:2.4.0-alpha04'
    api 'androidx.navigation:navigation-ui-ktx:2.4.0-alpha04'
}

Curr

This solution works for me. Changing from "2.3.5" to "2.4.0-alpha04" fix my error. Got some warnings ⚠ when building, but works. Thanks – Glycogen

Thanks, I just forgot to update the nav_version of androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version in the top-level gradle file to the same nave_version which is in the module's gradle file. – Ultramundane

Answer 3

All of these dependencies

androidx.navigation:navigation-fragment-ktx
androidx.navigation:navigation-ui-ktx
androidx.navigation:navigation-safe-args-gradle-plugin

need to be using the same version - ex: at the time of writing this it's 2.4.0-alpha10

Answer 4

Since the version v2.4.0-alpha02 was released, this known bug is no longer present.

Bug Fixes

• Safe Args no longer crashes when attempting to generate direction properties in Kotlin. (Id2416, b/188564435)

Hued

Still have this bug, any fix? – Clomb

The bug should be fixed by that release. If the problem still persist for you, place your comment on the tracker or create a new issue. – Hued

Got same bug on '2.4.0-alpha06' so it is not fully fixed or some regression happend – Meanwhile

Sounds like a regression bug then @MichałTajchert, in such case I’d bet there’s an existing issue on the tracker. – Hued

Answer 5

just update the safe-args dependency to the latest version(>=2.4.0-rc01) too!:

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.0-rc01"

Bennet

Answer 6

in my case, I get this error for my new module. I added the safe-args classPath in build.gradle (project)

KOTLIN-DSL:

    "classpath"(group = "androidx.navigation",name = "navigation-safe-args-gradle-plugin", version = "2.4.1")

without the plunging in my module build.gradle. so I added this on top of build.gradle:

id("androidx.navigation.safeargs.kotlin")

GROOVY:

classpath  "navigation-safe-args-gradle-plugin : 2.4.1"

and:

id 'androidx.navigation.safeargs.kotlin'

Entebbe

Answer 7

Please change your build.gradle(:app) file

from

apply plugin: "androidx.navigation.safeargs.kotlin"

to

apply plugin: "androidx.navigation.safeargs"

Answer 8

2.4.0-beta02 at this moment available
