cannot access viewBinding

Question

I'm now using viewBinding with Kotlin.

here is my build.gradle

enable ViewBinding and has auto import ViewBinding dependency.

but Android Studio still shows error like this Android Studio Error

but I can build and run with no problem.

and if I add viewBinding in dependencies, then the error is gone.

Does anyone know why?

UPDATE:

I know why. I'm using AndroidX, and the IDE says can not access 'android.viewbinding.ViewBinding', but my dependency is AndroidX, it is 'androidx.viewbinding.ViewBinding', package name changed.

SOLUTION: add android.useAndroidX=true to project gradle.properties file.

global gradle.properties setting does not work, don't know why.

@Bek I'm awayls use the last version. thanks for comment, I know why, see my update. — Joky, Jan 08 '21 at 02:53
Try to add `android.useAndroidX=true` to `gradle.properties` file then invalidate cache restart — Bek, Jan 08 '21 at 04:29
@Bek It is work after I add android.useAndroidX=true to project gradle.properties file. But it already added in global gradle.properties file. — Joky, Jan 08 '21 at 06:09

Facing same issue exact error yesterday. Solution work for me is

Step 1- Remove .Idea Folder
Step 2- Close android studio
Step 3- Reopen android studio with same project path (This will genarate new .Idea folder)

and Error is gone

Making sure

android.useAndroidX=true. inside gradle.properties file
inside app build.gradle

 buildFeatures {
       viewBinding true
 }

Always Use folder structure with samll case latter only class name is allowed to be Uppercase
If you are using any Copyright-Comment at top of xml or Layout tag without variable tag or we can say without any data then remove that and try to clean/rebuild project

I had this problem or did I? I found that the find in Android Studio was including old projects which did have kotlinx.android.synthetic imports. Could not find out how this occurred so closed studio and rm -rf the .idea. Not only did it cure the problem but speed it back up to a usable state. (Still not as good as VS Code) Hope it helps someone and ask an adult before deleting .idea in your project.

Yes, closed Android Studio then deleted the ".idea" folder solved this issue. Thank you – hoanngothanh Aug 04 '21 at 08:55

For me the error fixed when I changed the viewBinding build option to true in the module-level build.gradle file from Groovy mode to Kotlin mode, as shown below :

android {
    ...
    buildFeatures {
        viewBinding = true
    }
}

I'm not sure but the problem may lie in the fact that you're using both dataBinding and viewBinding. Try removing one of them then rebuild your Android Studio project.

I fixed it by adding in build.gradle

plugins{
    id 'kotlin-android'
}

android{
    buildFeatures{
        viewBinding true
    }
}

I got the same problem and this is the solution I got

go to the project gradle.properties
delete the android.useAndroidX=true line (in my enviroment this is set by default)
Sync gradle
add the deleted line again
Sync again

I noticed that the gradle has a comment that said that this setting was a duplicate so im guessing there was some kind of internal conflict

Used environment:

Android Studio Flamingo|2022.1 Patch 1
Build #AI-222.4459.24.2221.9971841, built on April 20, 2023

cannot access viewBinding
