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

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?

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);
}
}

Unable to find the place in google map using Android in specific radius

I want to find places of interest under a specific radius using Android. I am working in this way
String uri = "geo:"+ 40.007620 + "," + -75.160264 +"&q=child hospitals";
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
But when I run the application, It opens the google maps but does not mark the child hospitals. Any wrong here?

Try this,
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("geo:<40.007620>,<-75.160264>?q=<40.007620>,<-75.160264>(child hospitals)"));
startActivity(intent);

Please check below reference which will guide you to how to pass or format map intent query data :
https://developers.google.com/maps/documentation/android-api/intents
Example :
Uri gmmIntentUri = Uri.parse("geo:40.007620,-75.160264?q=" + Uri.encode("child hospitals"));

Humty you can try to this code hope this can help you..
Uri gmmIntentUri = Uri.parse("geo:40.007620,-75.160264?z=10&q=child hospitals");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

You can try something like this :
String urlAddress =
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=lat,lng&radius=500&type=city hospital&keyword=hospital&key=YOUR_API_KEY
which you can pass to
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlAddress);
startActivity(intent);
This will get opened in Google Maps with the results w.r.t provided radius. It works also same mentioned in below doc reference.
https://developers.google.com/places/web-service/search
Url to test :
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=18.590478,73.727191&radius=50000&type=child%20hospital&keyword=child%20hospital&key=PASTE_YOUR_API_KEY

Start Google Map Intent

hi i wanted to make a button which is the button will start google map intent
with my current location and destination location
how to make a google map automaticlly detect my location and destination longitude and lat?
where i put that longi and lat?
i want that map directly draw the direction to destination
final Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?"

intent.setClassName("com.google.android.apps.maps","com.google.android.maps.MapsActivity");
startActivity(intent);
alr tried this code but not working

Try using one of these with the View intent:
geo:latitude,longitude
geo:latitude,longitude?z=zoom
geo:0,0?q=my+street+address
geo:0,0?q=business+near+city
Something like:
Uri uri = Uri.parse(<ONE OF THE ABOVE STRINGS>);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);

Try this one:
String url = "http://maps.google.com/maps?saddr="+currentLattitude+","+currentLongitude+"&daddr="+targetLat+","+targetLang+"&mode=driving";
it should work.

Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=srcLatitude,srcLongitude&daddr=destLatitude,destLongitude"));
startActivity(intent);
// srcLongitude/Latitude = current Location`s longitude/latitude
// destLongitude/Latitude = Destination Location`s longitude/latitude

How to draw a route between two markers points on Google Maps v2?

Suppress chooser dialog when calling Google map using intent

I want to call google map intent without showing "Complete Action Dialog"?
Is it possible? Here is my code.
String uri = "http://maps.google.com/maps?saddr=" + Utils.getLatitude(ShowDetails.this)+","+Utils.getLongitude(ShowDetails.this)+"&daddr="+userLatitude+","+userLongitude;
startActivity(new Intent(android.content.Intent.ACTION_DEFAULT, Uri.parse(uri)));
I dont want to show below dialog when calling google map intent . Any Help is appreciated .

Below code helps me to solve my question.
String uri = "http://maps.google.com/maps?saddr=" + Utils.getLatitude(ShowDetails.this)+","+Utils.getLongitude(ShowDetails.this)+"&daddr="+userLatitude+","+userLongitude;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

Use the Google Maps URI rather than "http://[...] "
It goes something like this:
String uri = "geo:" + latitude + "," + longitude
Check out http://developer.android.com/guide/appendix/g-app-intents.html for the info.

Try ACTION_VIEW instead of ACTION_DEFAULT:
String uri = "geo:"+ latitude + "," + longitude;
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
check this Android doc Intents List and browse to "Google Maps".
