Unable to add window -- token null is not valid; is your activity running?

[jonrysimbolon]

I want to initialize popup dialog with @ApplicationContext but still show

"Unable to add window -- token null is not valid; is your activity running?"

this is mine

Loading.kt

@ActivityScoped
class Loading @Inject constructor(
    @ActivityContext var context: Context
) : CustomDialog {

    private val dialog = Dialog(context)
    private val constraintLayout = ConstraintLayout(context)
    private val inflater = LayoutInflater.from(context)

    init {
        init()
    }

    override fun init() {
        val dialogView = inflater.inflate(R.layout.dialog_loading, constraintLayout)
        dialog.setContentView(dialogView)
        dialog.window?.apply {
            setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
            setDimAmount(1f)
            setFlags(
                WindowManager.LayoutParams.FLAG_DIM_BEHIND,
                WindowManager.LayoutParams.FLAG_DIM_BEHIND
            )
        }
        dialog.setCancelable(false)
    }

    override fun show(show: Boolean) {
        dialog.let {
            if (show) {
                it.show()
            } else {
                it.dismiss()
            }
        }
    }
}

Module.kt

@Module
@InstallIn(ActivityComponent::class)
object DialogModule{

    @ActivityScoped
    @Provides
    fun provideLoadingDialog(
        @ApplicationContext context: Context
    ): CustomDialog = Loading(context)

and snippet of

HomeFragment.kt

@Inject
lateinit var loadingDialog: CustomDialog

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    loadingDialog.show(true)
}

How do i fix it ?

Sorry, that is not a Dagger error, so we won't be able to help here. You can try asking your question on StackOverflow.

i'm sorry before sir, but if not use hilt, my code is work (i use lazy), i just want to show the dialog popup with hilt, if my question makes you confused, i'm sorry in advance 🙏

FWIW, use @ActivityContext instead of @ApplicationContext in your provideLoadingDialog() should make it work.
