action cannot be found from the current destination

Question

I have very simple navigation and when I attempt to go to new fragment I get this error:

java.lang.IllegalArgumentException: Navigation action/destination com.my.app:id/action_settingsFragment_to_profileFragment cannot be found from the current destination Destination(com.my.app:id/mainFragment) label=fragment_main class=com.my.app.main.MainFragment

navigation

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_graphs"
    app:startDestination="@id/mainFragment">
    <fragment
        android:id="@+id/mainFragment"
        android:name="com.my.app.main.MainFragment"
        android:label="fragment_main"
        tools:layout="@layout/fragment_main" >
        <action
            android:id="@+id/action_mainFragment_to_laundriesFragment"
            app:destination="@id/laundriesFragment" />
    </fragment>
    <!-- other fragments here...  -->
    <fragment
        android:id="@+id/settingsFragment"
        android:name="com.my.app.main.SettingsFragment"
        android:label="fragment_settings"
        tools:layout="@layout/fragment_settings" >
        <action
            android:id="@+id/action_settingsFragment_to_newOrderFragment"
            app:destination="@id/newOrderFragment" />
        <action
            android:id="@+id/action_settingsFragment_to_profileFragment"
            app:destination="@id/profileFragment" />
    </fragment>
    <fragment
        android:id="@+id/profileFragment"
        android:name="com.my.app.main.ProfileFragment"
        android:label="fragment_profile"
        tools:layout="@layout/fragment_profile" >
    </fragment>
</navigation>

SettingsFragment.kt (redirect code)

when (position) {
    0 -> {
        //....
    }
    1 -> {
        navController.navigate(R.id.action_settingsFragment_to_profileFragment)
    }
    2 -> {
        //...
    }
}

Any idea?

Update

I've managed to redirect to profileFragment with following code, but when I hit back button it closes the app instead of back to settingsFragment

private fun GenerateItems(){
    when (position) {
        0 -> {
            //
        }
        1 -> {
            this@SettingsFragment.navigateTo(ProfileFragment())
        }
        2 -> {
            //
        }
    }
}

private fun navigateTo(fragment: Fragment) {
    val transaction =  (activity as FragmentActivity).supportFragmentManager
            .beginTransaction()
            .replace(R.id.fragmentFragmentId, fragment)

    transaction.commit()
}

Any idea about back button issue?

NavDirections action = SpecifyAmountFragmentDirections .actionSpecifyAmountFragmentToConfirmationFragment(); Navigation.findNavController(view).navigate(action); — Eyosiyas, Apr 10 '21 at 08:46
@Eyosiyas not sure if I understand you correctly but I have something like this as well `override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) navController = Navigation.findNavController(view) }` — mafortis, Apr 10 '21 at 08:50
Check this link https://developer.android.com/guide/navigation/navigation-getting-started#ensure_type-safety_by_using_safe_args — Eyosiyas, Apr 10 '21 at 08:52
@Eyosiyas thank you but I really don't understand what `SpecifyAmountFragmentDirections` or `actionSpecifyAmountFragmentToConfirmationFragment` are referring to. — mafortis, Apr 10 '21 at 08:54
When you use Safe Args it will automatically generate for you. — Eyosiyas, Apr 10 '21 at 08:57
@Eyosiyas is that possible that you share an answer? cause honestly I don't see this conversation getting any outcome for solving my issue. — mafortis, Apr 10 '21 at 08:58

java.lang.IllegalArgumentException: Navigation action/destination com.my.app:id/action_settingsFragment_to_profileFragment cannot be found from the current destination Destination(com.my.app:id/mainFragment) label=fragment_main class=com.my.app.main.MainFragment

The exception means that you are trying to use an action named as action_settingsFragment_to_profileFragment that can not be found in the current destination/fragment which is MainFragment

As action name implies: It's an action that you use to move from settingsFragment to profileFragment, so can only use this action within the settingsFragment.

Note: The auto generated action name is just an indication for the source & destination, but it can mean something else if the naming is messed up.

Confirming that in navGraph:

<fragment
    android:id="@+id/settingsFragment"
    android:name="com.my.app.main.SettingsFragment"
    android:label="fragment_settings"
    tools:layout="@layout/fragment_settings" >
    <action
        android:id="@+id/action_settingsFragment_to_newOrderFragment"
        app:destination="@id/newOrderFragment" />
    <action
        android:id="@+id/action_settingsFragment_to_profileFragment"
        app:destination="@id/profileFragment" />
</fragment>

This part of navGraph is when you at the settingsFragment, and there are two actions where you can go from the settingsFragment to newOrderFragment fragment or to profileFragment; or even pop up the backstack to return to the previous fragment

If you really want to go to the SettingFragment from the MainFragment, then you need to create a new action in the MainFragment as there is no one there, like below

<fragment
    android:id="@+id/mainFragment"
    android:name="com.my.app.main.MainFragment"
    android:label="fragment_main"
    tools:layout="@layout/fragment_main" >

    <action
        android:id="@+id/action_mainFragment_to_laundriesFragment"
        app:destination="@id/laundriesFragment" />

    <action
        android:id="@+id/action_mainFragment_to_settingsFragment"
        app:destination="@id/settingsFragment" />
</fragment>

UPDATE:

I've managed to redirect to profileFragment with following code, but when I hit back button it closes the app instead of back to settingsFragment

You need to add app:popUpTo="@id/settingsFragment" and specify the fragment that you want the back stack popup to when you click the back or parent buttons

<fragment
    android:id="@+id/settingsFragment"
    android:name="com.my.app.main.SettingsFragment"
    android:label="fragment_settings"
    tools:layout="@layout/fragment_settings" >
    <action
        android:id="@+id/action_settingsFragment_to_newOrderFragment"
        app:destination="@id/newOrderFragment" />
    <action
        android:id="@+id/action_settingsFragment_to_profileFragment"
        app:popUpTo="@id/settingsFragment"
        app:destination="@id/profileFragment" />
</fragment>

To use the generated directions class: dd apply plugin: "androidx.navigation.safeargs" plugin to the gradle module level

Add the class path to the gradle app level:

buildscript {
    repositories {
        google()
    }
    dependencies {
        def nav_version = "2.3.5"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
    }
}

Then Build > Make project to generate the direction class. and In navigation use the generated class

navController.navigate(SettingsFragmentDirections.actionSettingsFragmentToProfileFragment())

Also check documentation for more info

so what you mean is in order to my navigation work i need to add `action_mainFragment_to_settingsFragment` in my main fragment right? – mafortis Apr 11 '21 at 04:03
Yes.. That if you want to go from mainFragment to settingFragment. And use navController to perform the navigation programmatically on some action – Zain Apr 11 '21 at 04:06
gotin to `settingsFragment` from `MainFragment` is not my problem, my problem is going to `ProfileFragment` from `settingsFragment` **PS:** I just tried your suggestion still getting same error – mafortis Apr 11 '21 at 04:08
I've added screenshot. – mafortis Apr 11 '21 at 04:11
You do that from the settingsFragment class? – Zain Apr 11 '21 at 04:18
do what? navigate `navController.navigate(R.id.action_settingsFragment_to_profileFragment)`? If so, yes I'm doing this from my `SettingsFragment.kt` – mafortis Apr 11 '21 at 04:18
Yes... Which is in the when block – Zain Apr 11 '21 at 04:19
yes that's inside my `SettingsFragment.kt` file – mafortis Apr 11 '21 at 04:21
Do you get the same behavior when using the geneated direction class instea of the id of the action? – Zain Apr 11 '21 at 04:31
I haven't tried that how should I do that? – mafortis Apr 11 '21 at 04:33
I've managed to make it work but there is small issue would you mind see my update? – mafortis Apr 11 '21 at 04:37
still closing the app – mafortis Apr 11 '21 at 04:48
It won't work unless you use the action id or the generated direction class – Zain Apr 11 '21 at 04:51
would you mind show me how? cause this was the only way I could make it work maybe your way can do the trick as well. – mafortis Apr 11 '21 at 04:52
Because you avoided using the navGraph in your solution – Zain Apr 11 '21 at 04:52
please show me your way, it might be better than mine. – mafortis Apr 11 '21 at 04:53
so far only way it works is my update part :/ – mafortis Apr 11 '21 at 05:34
@mafortis please make sure that you added the `android:id="@+id/action_settingsFragment_to_profileFragment"` in the NavGraph, setting fragment, and in java/kotlin let the IDE auto-complete the generated Directions class its names should look like `SettingsFragmentDirections` – Zain Apr 11 '21 at 13:25

  if (findNavController().currentDestination?.id != R.id.addressDeleteBottonSheetFragment) {
            findNavController().navigate(
                AddAddressFragmentDirections.actionAddressFragmentToAddressDeleteBottonSheetFragment(
                    selectedAddressId
                )
            )
        }
