Android Question How to reset a google map and erase markers

[Mark Read]

I have an app with three components: a button, an edittext and a webview.

The button uses a search criteria entered in the edittext to generate markers for google maps. My problem is how to clear the map if a new search is required?

A html file is created locally which is read into the webview, therefore I would have at least the possibilty to:

1. Delete the webview and make a new one
2. load a dummy file with nothing in it and then the real file - tried this, did not work
3. Do something else?

Ideas please.

You can always call WebView.LoadUrl to load a new page.

I tried that Erel, I loaded an empty page with Webview.Loadhtml (as I said in point 2 above) but it didn't work. The page I am loading (as in the screenshot) is created using javascript. I am wondering if the new page uses information from the cache? If so, how can I clear the cache?

This is an example of the file which is created by my app and displayed in the webview.

You can clear the cache with JavaObject:

Dim jo As JavaObject = WebView1
jo.RunMethod("clearCache", Array(true))
