Example crashes when trying to access remote preference

[a1b2c]

Scope request works perfect but crash when trying to edit RemotePreference or openFileOutputStream. I just added

val pref : SharedPreferences? = service.getRemotePreferences(packageName)
pref?.edit()?.putBoolean("temp", true)?.apply()

to onServiceBind method of callback like this

override fun onServiceBind(service: XposedService) {
mService = service
binding.binder.text = "Binder acquired"
binding.api.text = "API " + service.apiVersion
binding.framework.text = "Framework " + service.frameworkName
binding.frameworkVersion.text = "Framework version " + service.frameworkVersion
binding.frameworkVersionCode.text = "Framework version code " + service.frameworkVersionCode
binding.scope.text = "Scope: " + service.scope
service.requestScope("com.android.settings", mCallback)
val pref : SharedPreferences? = service.getRemotePreferences(packageName)
pref?.edit()?.putBoolean("temp", true)?.apply()
}

here is exception
