How to use GeoPicker in your Android app?

Now, GeoPicker 1.1 support the Intent invoke, you can use it in your app.
If you want to ask user to choose a location, you can invoke GeoPoint by Intent. And it will return the coordinate the user picks.

-invoke GeoPicker

Intent intent = new Intent(Intent.ACTION_PICK);
intent.setClassName("", "");

/*option: the initial locaiton*/
intent.putExtra("lat", 25135022);
intent.putExtra("lon", 121516890);

startActivityForResult(intent, REQUEST);

-return coordinate

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode ==REQUEST && resultCode ==Activity.RESULT_OK){
int latE6 = data.getIntExtra("lat", 0);
int lonE6 = data.getIntExtra("lon", 0);
-Show GeoPicker on Android Market, if GeoPicker isn't installed.
List resolvList=getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
Uri uri = Uri.parse("market://search?");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
