How to list markers in Google Map using RxJava?

Question

Java

There is a list of cities with a name and coordinates. (A list with 200000+ elements)
How can I display all this data in a background thread using RxJava, since when outputting through a normal loop in the main thread, the application crashes

Answer 1

No way, in android: display something on the screen = do it in the UI thread. Another question is why display 200 thousand elements at once when you need to use clustering.
