What are we building:

Download the source code here Download

What is required?

  1. Install google maps api for flash ( Emanuele Feronato tutorial )
  2. Flash IDE ( Ability to compile & export apk for android ) Im currently using flash CS5
  3. AS3 knowledge ( duh )

once you install google maps api for flash, navigate to the components and drag out a GoogleMapsLibrary component to the library.

Under the document class enter Main ( the external AS3 file ) which we’ll be having the code in.

Save the Fla file and in the same directory create an AS file and save it as Main.as, Copy & Paste the following code in Main.as :

package  {

	//Flash imports
	import flash.display.MovieClip;
	import flash.sensors.Geolocation;
