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?

Do you have correct import?

[Subramanian Iyer]

I have:

open class JSONObject

Do I need something else?

[Shohei Kawano]

If you have defined JSONObject just like the snippet you wrote above, instead of defining it by your own, you should import it to use it

[Subramanian Iyer]

Right but what's the import? Is it import org.json? Because then my ide is saying json is an unresolved reference.

[Feri Nagy]

Try import org.json.JSONObject

[Subramanian Iyer]

Tried that too and my ide still says that json is an unresolved reference

[Feri Nagy]

Can you post the whole file - relevant JSON code and imports?

[Subramanian Iyer]

Problem went away! Just had to add a dependency to a gradle file and then wait a while
