When I try to initialize viewmodel in an Activity which extends ComponentActivity, I can use “by viewModels(..)” . However if I try to instantiate the same in an activity that extents AppCompactActivity, it remains unresolved.

I checked the source code of ‘by viewModel’, looks like its only applicable on ComponentActivity,

public inline fun <reified VM : ViewModel> ComponentActivity.viewModels(
    noinline extrasProducer: (() -> CreationExtras)? = null,
    noinline factoryProducer: (() -> Factory)? = null
): Lazy<VM> {
    val factoryPromise = factoryProducer ?: {
        defaultViewModelProviderFactory
    }

    return ViewModelLazy(
        VM::class,
        { viewModelStore },
        factoryPromise,
        { extrasProducer?.invoke() ?: this.defaultViewModelCreationExtras }
    )
}

Is there a way in which I can also use this function under AppCompactActivity?

I have tried adding the following dependencies:

implementation("androidx.activity:activity-ktx:1.9.0")
implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:2.8.3")
implementation("androidx.lifecycle:lifecycle-runtime-ktx:2.8.3")

implementation("androidx.fragment:fragment-ktx:1.8.1")
implementation("androidx.core:core-ktx:1.13.1")

implementation("androidx.navigation:navigation-fragment-ktx:2.7.7")
implementation("androidx.navigation:navigation-ui-ktx:2.7.7")
implementation("androidx.lifecycle:lifecycle-livedata-ktx:2.8.3")
