Updating a google maps gui

Question

After the initial onCreate method in Android, are there any other methods to update or change the original content in the onCreate method.

For example I initiate a GoogleMap in the onCreate method, with polylines and circles drawn over it. Is there a way to update this map so the old polylines and circles are removed and replaced by new ones?

Cheers in advance.

Answer 1

You can call map.clear() which removes all markers, polylines etc. and leaves a plain map. Now you can add some new stuff.

If you wanna remove just specific map objects like a polyline hold a reference and call remove.
