Hey is overriding a virtual fun with a reified type a bad idea?

https://developer.android.com/reference/kotlin/org/json/JSONObject. I'm trying to use a public method of this class as follows:

fun getSource(inp: JSONObject, key: String): String{
    return JSONObject(inp.getString("_source")).optString(key)
}

My ide is saying that the public methods getString and optString are unresolved references. Anyone know what the issue might be?

Hi, With the new Kotlin feature Prototype of Context Receivers how can we create an extension function for this nesting and make it just one line? I've seen something online but I lost the link.

viewLifecycleOwner.lifecycleScope.launch {
    viewLifecycleOwner.repeatOnLifecycle(Lifecycle.State.STARTED) {
        locationProvider.locationFlow().collect {
            // New location! Update the map
        }
    }
 }

Is it necessarily better or "safer" to call shared prefs from an IO dispatcher?

supportActionBar?.setCustomView(R.layout.action_bar_textview)

Hey I am working in Android kotlin. I have response data, which I want to filter and extract data according. My Response look like this. Inside my response there is three field strength, quantity and subscription. First Block in for strength, second block is for quantity and third block is for subscription. I will explain in more details. For example I want to filter all subscription value who has 25 , 50 and 75 and their value of quantity and subscription are respectfully from the response. Note subscription value is in repoonse is hard code. In real response it will more than 3 categories. I am thinking to use Tree or Graph data structure, but I am not 100% sure. I am doing correct or not. Is there any idiomatic kotlin way to achieved this. I want code to be Performance optimisation, speed, memory etc. I'll send these filter list to RecylerView and will manage to show like below image. Can someone guide me how to filter list through response. Thanks
