kotlinlang #android

so was able to finally solve my issue, after lots of painstaking debugging and logs, so seems when the process is killed all user variables are set to null so even if am reinialising those variables their being recalled from null source hence null setting null, so instead doing savedInstanceState on every activity calling that object(Since its a singleton) i used the BaseActivity to saveState and update the object globally when the app is recreated so all other activities just inherit from this.

design patterns are not tied to a specific language

There isn’t a one size fits all answer to your question. Your design should be dictated by the problem space, your skillset and that of your teammates. It’s a thing that changes, and evolves ( and devolves ) if your not careful. Take the time to consider the question you are asking, and try to not see things from the point of view of needing the one true answer. There usually is not one.

Is there some way to get rid of this horrible code?

Copy code

val parcelable = extras.getParcelableArray(LocationPicker.INPUT_POLYGON) as Array<Parcelable>
        for (e in parcelable) {
            inputPolygon.add(e as LatLng)
        }

I cannot find a way to make the compiler happy. Array<Parcelable> vs Array<LatLng>. Generics covariance once more

or an extension casting method

Copy code

@Suppress("UNCHECKED_CAST")
fun <T : Any> Bundle.getTypedParcelableArray(key: String) = getParcelableArray(key) as Array<T>

Copy code

inputPolygon.addAll(bundle.getTypedParcelableArray<LatLng>(LocationPicker.INPUT_POLYGON))
