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

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.

Answer 1

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

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

 buildFeatures {
       viewBinding true
 }

3. Always Use folder structure with samll case latter only class name is allowed to be Uppercase
4. 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

Answer 2

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.

Answer 3

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 don't know why but my same problem got solved by removing below line from gradle.properties(project properties)

android.useAndroidX=true

Answer 5

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.

Answer 6

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

1. go to the project gradle.properties
2. delete the android.useAndroidX=true line (in my enviroment this is set by default)
3. Sync gradle
4. add the deleted line again
5. 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

Answer 7

I fixed it by adding in build.gradle

plugins{
    id 'kotlin-android'
}

android{
    buildFeatures{
        viewBinding true
    }
}
