App Inventor and embedded HTML/JavaScript

Get coordinates for any Location on Google Maps back to App Inventor

It was asked in the App Inventor Forum, is there a capability in AppInventor to get co-ordinates for any location clicked on Google Maps and pass that back to the application? App Inventor together with embedded HTML/JavaScript can do that!

The example uses the Google Maps API V3. For your own app, first obtain an API key. Then use your API key for your queries to the Google Maps API inside the embedded HTML/Javascript document.

I used one of the map icons from Nicolas Mollet as marker , you can easily adjust that.

The tools extension offers the method PathToAssets which always returns the correct path to the assets.

Questions and Answers

Q1: I don't understand how it can take the selected position (with this app) to my 'blocks' as an argument of Latitude and Longitude??
A: In the example the selected coordinates are displayed in the title of the app. See the screenshot below how to get lat and long.

Btw. I recommend you to do the MIT tutorials first to learn the basics of App Inventor.
