LiveData not updating after changed using Handler PostDelayed?

Question

Here's my ViewModel

class MainViewModel(repository: MainActivityRepo) : ViewModel() {

val isLoading: MutableLiveData<Boolean> = MutableLiveData()

init {
    isLoading.value = false
    android.os.Handler().postDelayed({
        isLoading.value = true
        Timber.d("isCalled")
    }, 5000L)
     }
}

I debugged and checked and the log is working perfectly.

The first value of boolean is set correctly, while the second is not

On background thread, you can use post value instead of set value which will solve your problem!

As mentioned by Vikas you should use the postValue() method.

Handler().postDelayed({
    isLoading.postValue(true)
    Timber.d("isCalled")
}, 5000L)
