If you use the gps receiver, the receiver MUST get a satellite fix. The initial fix may take 30 to 60 seconds; subsequent fixes will take about 20 seconds or less depending on many factors.

Have you read Using the Location Sensor the section that explains that?

The html file does work in the webviewer, asks user for permission to access Location (Location services need to be ON) No reason why this method would be any quicker than built-in blocks / component method, so may as well use the built in method.

5 posts were split to a new topic: How can I use the WebViewString?

You could try something like this that uses WIFI/network instead of the gps receiver hardware.
If you are WIFI connected, it should provide an instantaneous location response.
passiveProvider

This works on my 4.2 phone with passive provider. It might also work with network provider. It does not work with my 8.1 Android. :cry:

Be sure to unlock the Provider when you are finished experimenting.

Does the example help?
