Is there a trick to using View Binding with multiple modules? The bindings aren’t being generated when I add it to a second module.

With DataBinding you need to enable it in Gradle for both library modules and the app module as well

[wasyl]

Even if app module doesn’t contain views or bindings itself

It’s still not working for me after I enabling it in the app module. I get

error: package mypackage.databinding does not exist
import mypackage.databinding.MyLayoutBinding

do you have a custom binding adapter? or using <data> tag also using it in your xml like this:

<TextView
  app:customBinding="@{variable1}" />

you might want to check if the customBinding match with your data type

sometimes data binding won’t generated any layout if there’s an error of it
1. wrong syntax
2. wrong data type provided
3. unescaped strings
4. Integer data type but using it in CharSequence attributes, e.g: android:text="@{thisIntegerValue} won’t works

I’m using view binding, not data binding.

[miqbaldc]

does both your modules already include viewBinding { isEnabled = true } ?

Yes

Same as this? https://issuetracker.google.com/issues/140955511

It’s working for my multi-module application. Also have a look at this: https://issuetracker.google.com/issues/149045351

This was resolved by updating my build tools version to 3.6.1
