Android intent for opening both Waze and Google maps

Question

There are a few similar posts but I couldn't find an exact one. basically, I want to open both Google maps and Waze with the same intent. At first I tried this:

final String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(intent);

Waze navigated directly to the right location and Google maps opened the right place. then I realized that Google maps doesn't put a pin on the location so it's hard for the user to know where it is exactly. So I looked around and realized that Google maps requires the "?q=..(label)" for that... I changed the uri construction to:

final String uri = String.format(Locale.ENGLISH, "geo:%f,%f?q=%f,%f (%s)", latitude, longitude, latitude, longitude, name);

But then Waze did 2 things: navigated to the right place AND run a search on the label. This required the user to click the back button to close the search results screen and remain with the navigation to the right place.

I looked everywhere for an answer but failed to find a solution that will achieve both. At first I thought that it's not possible and Waze has a bug... but then I noticed that Facebook messenger is doing exactly what I want. when clicking on a message with a location it will open both apps: Google maps will have a pin (with a label) and Waze will navigate straight to that location without running a search.

Few questions about the above: 1. (Of course) How can I achieve that? 2. How can I know how the Facebook messenger's intent being built? (Can I catch it in anyway) 3. What's the reason behind having the label only with the "?q=.."?

Thanks

Answer 1

Never mind. I was able to intercept the Facebook messenger with the below app and figured that the URI should be as follows:

String.format(Locale.ENGLISH, "geo:0,0?q=") + android.net.Uri.encode(String.format("%s@%f,%f", label, latitude, longitude), "UTF-8");
