I have previously changed some code in my project and now there is the following error thrown during compilation for the following auto-generated class:

DataBinderMapperImpl.java : cannot find symbol "AdvancedBoxBindingImpl" (in line 'import ...databinding.AdvancedBoxBindingImpl;')

The AdvancedBox is included in the the layout fragment_config.xml like this:

<layout xmlns:bind="http://schemas.android.com/tools">

    <data>

        <import type="android.view.View"/>

        <variable name="viewModel" type ="...GlobalConfigViewModel"/>

    </data>

...

<....AdvancedBox

                android:id="@+id/advancedBox"

                android:layout_width="match_parent"

                android:layout_height="wrap_content"

                app:viewModel = "@{viewModel}"

                android:visibility="@{viewModel.advancedShown ? View.VISIBLE : View.GONE}"/>

...

</layout>

The advanced_box.xml looks like this:

<layout>

    <data>

        <import type="android.view.View"/>

        <variable

            name="viewModel"

            type="...GlobalConfigViewModel" />

    </data>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    ....

The binding in the AdvancedBox-class is instantiated like this:

class AdvancedBox : LinearLayout{

    private lateinit var mBinding: AdvancedBoxBinding

    init{

        mBinding = AdvancedBoxBinding.inflate(inflater, this, true)

    }

All of this previously worked, but I have recently updated Android Studio and made changes in the Code.

Additional Information:

• gradle.properties has the attribute 'android.databinding.enableV2=true'


• I have tried File->Invalidate Caches and Restart

Any suggestions on what might be the problem?

where have you specified the binding class inside xml? I think that's the issue

<layout>

    <data class="AdvancedBoxBinding">

        <import type="android.view.View"/>

        <variable

            name="viewModel"

            type="...GlobalConfigViewModel" />

    </data>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Possible problem with the way data has been bound to the view.
In my case, I had a model :

<data>

    <variable name="user" type="zw.org.coop.models.User"/>

</data>

but because of copy pasting, I had a typo like :

<TextView

    android:id="@+id/fullName"

    style="@style/styleEditText"

    android:layout_width="match_parent"

    android:layout_height="35dp"

    android:padding="5dp"

    android:text="@{user.user.firstName}"

    android:textSize="12sp"

    tools:text="Dean Kaila" />

where user.user.firstName was not intend but user.firstName

Would've been better if Jetbrains had some intellisense going on to help with such issues, but yeah, that was a good 2 days for me.
Hope this helps someone.
