How to Check for "enabled_notification_listeners" Programmatically?

I need to check that either my application's service is Enabled or Not in "Notification Access".

I am using this code to check this. The code is running fine on Nougat, but it crashes on Marshmallow. How can I do that on Marshmallow?

android.provider.Settings.Secure.getString(this.getContentResolver(), "enabled_notification_listeners").contains(getApplicationContext().getPackageName())

This is the Error in LogCat:

You could also check your service directly:

context?.applicationContext?.let {

  val componentName = ComponentName(it, YourNotificationListenerService::class.java)

  val enabledNotificationListeners: String? =
                Settings.Secure.getString(it.contentResolver, "enabled_notification_listeners")

  return enabledNotificationListeners != null && enabledNotificationListeners.contains(
                componentName.flattenToString())
}

The downside is that you need access to the context.

Use this function to get our package have notification listener or not. This Function will returns True or false.

boolean hasNotificationAccess()
    {
        ContentResolver contentResolver = this.getContentResolver();
        String enabledNotificationListeners = Settings.Secure.getString(contentResolver, "enabled_notification_listeners");
        String packageName = this.getPackageName();

        // check to see if the enabledNotificationListeners String contains our package name
        return !(enabledNotificationListeners == null || !enabledNotificationListeners.contains(packageName));
    }
