How can I ask the user for Yandex Navi or Google Maps? How can I direct it?

Question

I have two values in latitude and longitude. I have a key. This button must have two options to go to location information,Yandex Navi and Google Maps. When I click on the button, I want to know which one would like to open it. How can I do that?

Answer 1

You can use Intent.createChooser() like:

String url = "yandexmaps://maps.yandex.ru/?pt=" + latitude + "" + longitude + "&z=12&l=map";
Intent intentYandex = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intentYandex.setPackage("ru.yandex.yandexmaps");

String uriGoogle = "geo:" + latitude + "," + longitude;
Intent intentGoogle = new Intent(Intent.ACTION_VIEW, Uri.parse(uriGoogle));
intentGoogle.setPackage("com.google.android.apps.maps");

String title = "Select";
Intent chooserIntent = Intent.createChooser(intentGoogle, title);
Intent[] arr = new Intent[1];
arr[0] = intentYandex;
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arr);
startActivity(chooserIntent);

Andrii Omelchenko's answer always opens Google Maps for me. But after change google and Yandex order for chooserIntent, it is worked in my case:

    val uriYandex = "yandexnavi://build_route_on_map?lat_to=${latitude}&lon_to=${longitude}"
    val intentYandex = Intent(Intent.ACTION_VIEW, Uri.parse(uriYandex))
    intentYandex.setPackage("ru.yandex.yandexnavi")

    val uriGoogle = Uri.parse("google.navigation:q=${latitude},${longitude}&mode=w")
    val intentGoogle = Intent(Intent.ACTION_VIEW, uriGoogle)
    intentGoogle.setPackage("com.google.android.apps.maps")

    val chooserIntent = Intent.createChooser(intentYandex, title)
    val arr = arrayOfNulls<Intent>(1)
    arr[0] = intentGoogle
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arr)

    val activities = packageManager.queryIntentActivities(chooserIntent, 0)
    if(activities.size>0){
        startActivity(chooserIntent)
    }else{
        //do sth..
    }

If it absolutely has to be either Google Maps or Yandex Navi, the easiest way would probably be to figure out which one the user wants to use (via a dialogue or similar), and then set that as the target of a Map Intent. For example, here's an intent from Google's Android documentation that targets Google Maps by app name:

// Creates an Intent that will load a map of San Francisco
Uri gmmIntentUri = Uri.parse("geo:37.7749,-122.4194");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, 
gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

This should also work with Navi by setting the package to "ru.yandex.yandexnavi".

Note, though, that a more standard way to do this would be with a Map Intent that doesn't specify the targeted app. That way, all you would have to provide is the coordinates, and then the user could use their app of choice:

public void showMap(Uri geoLocation) {
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(geoLocation);
    if (intent.resolveActivity(getPackageManager()) != null) {
      startActivity(intent);
    }
}
