Getting unresolved reference on Android S - Kotlin

Question

I'm trying to use new Notification API setForegroundServiceBehavior. However, when trying to create a build I'm getting an unresolved reference I believe in Android S in general. (I'm working on a different project using Java and there seems to be no problem.)

    val builder = Notification.Builder(this, CH_ID)
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        builder.setForegroundServiceBehavior(Notification.FOREGROUND_SERVICE_IMMEDIATE);
    }

Errors:

Unresolved reference: S
Unresolved reference: setForegroundServiceBehavior
Unresolved reference: FOREGROUND_SERVICE_IMMEDIATE

Gradle:

compileSdkVersion 31
buildToolsVersion "30.0.3"
defaultConfig {
    ...
    minSdkVersion 28
    targetSdkVersion 31

Don't know if it has anything to do with it, but I think it's recommended to use buildToolsVersion that is the same as compileSdkVersion . Maybe try "31.0.0" there – Selfaddressed

Tried changing buildToolsVersion to "31.0.0" but issue is still occurring. – Barnett

Try 1. syncing project with grade files 2. Invalidate cache and restart. – Aubade

no error am facing above code. may be check with invalidate cache and restart android studio will helps – Bookshelf

@Barnett did you try? – Aubade

As it turned out this was a problem caused by an outdated framework.jar being used in the project. Since it has higher priority during build time, the change in sdk is being overwritten/ignored. – Barnett

how did you resolved this? I'm getting same issue. – Baptism

Update you buildToolsVersion to “32.0.0” and compileSdkVersion and targetSdkVersion to 32. Or newer versions.
