Android Question webviewextras geolocation fatal signal problem

[cengolo]

I kindly as your help for a problem i have with webviewextras. I develop a wrapper android app for a map application. i have a webview, added chrome client and enabled javascript. for testing purposes, the webview only loads maps.google.com page and whenever i press find user location in the page, the application exits with the error below. is this a common problem and do you know a solution to this?
basically what i need is to load a map app in the webview and find the geolocation of the user and show it on the map. i checked the examples and gave neccesary permissions in the manifest editor, but i still get this fatal signal

On Android you should use native GoogleMaps instead of a Webview with a Map.

 

[cengolo]

unfortunately, if i use them, dont i have to purchase an api key and pay google for each transaction?

 

[DonManfred]

Native Android GoogleMaps and using Markers, Polygons and so on are free.
This is not true for the Javascript GoogleMaps which you want to implement. Here you need to have a Apikey. Check Googles Documentation about their plans to find out more. I can´t remember the link but it should be possible to find using Google or the forumsearch.

You need to have a Apikey if you want to use any Api from google though (Direction, Places and so on).
