android - Get selected location from Google Maps activity

Question

I'm trying to return the location selected by the user in the Google Maps Android application, but I can't seem to find information about how to achieve this task.

I created an Intent to open the GMaps Activity, but the user can't select a point on the map nor does the Activity return a point to my application when it is closed.

I'm using startActiviyForResult, since I'm expecting a result back from the Activity.

You could simply use PlacePicker instead of implementing your own MapActivity. You will need to add Google Play Services library reference in your project though.

Just startActivityForResult with the intent provided by PlacePicker.IntentBuilder

int PLACE_PICKER_REQUEST = 1;
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();

Context context = getApplicationContext();
startActivityForResult(builder.build(context), PLACE_PICKER_REQUEST);

And then receive the results in onActivityResult

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == PLACE_PICKER_REQUEST) {
    if (resultCode == RESULT_OK) {
        Place place = PlacePicker.getPlace(data, this);
        String toastMsg = String.format("Place: %s", place.getName());
        Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
    }
  }
}
