How to set the labels for source and destination in google maps programmatically in android?

I am using this code to open the Google Maps app in android.
if(source != null && destination != null) {
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?daddr="
+ destination.latitude + "," + destination.longitude + "(" + ADDRESS + ")"));
startActivity(intent);
} else {
Toast.makeText(context, "Please check your internet connection and try again!!", Toast.LENGTH_LONG).show();
}
What happens when it goes to the Google Maps app of android, at first it displays the ADDRESS in the destination box and "Your Location" in the source box but after that, it gets changed to "Point on Map". Is there any way by which I can avoid this? Or I am missing something?
Can anybody help me with this?

you can set markers to set Destination and Source Points on Google Maps
String uri = String.format(Locale.ENGLISH, "geo:%f,%f?z=17&q=%f,%f", sourcelatitude,sourcelongitude,destlatitude,destlongitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));

Not able to open directions in google map in android

I have one screen in app which shows address. Now I want to open google when while click on that address. And it have to show directions from current location to that address.
//code in app
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?daddr=28.5600697,77.2695753"));
startActivity(intent);
but it is not opening location only processing.

Try this
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?q=28.5600697,77.2695753"));
startActivity(intent);
and please let me know if it works.

Try something like this. this will Suppress chooser dialog when calling Google map using intent
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr="+Latitude+","+Longitude+"&daddr="+latitude+","+longitude));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

Try this code
float storeLatitude = Float.parseFloat(storeList.latitude + "");
float storeLongitude = Float.parseFloat(storeList.longitude + "");
String uri = String.format(Locale.ENGLISH, "http://maps.google.com/maps?daddr=%f,%f (%s)", storeLatitude, storeLongitude, "Store Address");
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);

First you need to fetch user's current Latitude and Longitude than use following :
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=" + mUserLatitude + ", " + mUserLongitude +
"&daddr=" + lat + ", " + lon));
startActivity(intent);
Where lat , lon is destination Latitude and Longitude resepectively.

open google maps through intent for specific location in android

I'm designing one application in which I want to show specific location on Map.
I'm passing String of address which is already placed on Google Map.
Following is my Intent code..
String url = "http://maps.google.com/maps?daddr="+address;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
But it gives me Google Map for getting direction. I know why that so, because I used daddr in url but I don't know what to use for specific location..Please tell me what to use there..

I have not tested this but you could try :
First method:
String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);
EDIT:
This might not work with Google maps 7,0
hence you could change the uri to :
Second option:
String geoUri = "http://maps.google.com/maps?q=loc:" + lat + "," + lng + " (" + mTitle + ")";
where mTitle is the name of the location.
Third option:
geo:0,0?q=my+street+address
Fourth option:
String map = "http://maps.google.co.in/maps?q=" + yourAddress;
Hope that works and helps :D..

Get Lat-Lng Using this web-service
http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false
Then Pass it to this code
String strUri = "http://maps.google.com/maps?q=loc:" + lat + "," + lng + " (" + "Label which you want" + ")";
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(strUri));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);
I hope it will help you
Thank you.

The latest version of map provides better solution. If you wish show an address on map use below code.
Uri mapUri = Uri.parse("geo:0,0?q=" + Uri.encode(address));
Intent mapIntent = new Intent(Intent.ACTION_VIEW, mapUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);
If you want to display using latitude and longitude values, use below method.
Uri mapUri = Uri.parse("geo:0,0?q=lat,lng(label)");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, mapUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);
Lat and lng being the latitude and longitude you wish to display, the label here is optional.

This will work like a charm. Make sure to check for existence for Google Maps, so this can work universally across all non Google devices also. It will open in a browser in such cases.
Also, remember, don't have www in the URL. Else this will not work.
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?q=loc:" + latitude + "," + longitude));
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // Only if initiating from a Broadcast Receiver
String mapsPackageName = "com.google.android.apps.maps";
if (isPackageExisted(context, mapsPackageName)) {
i.setClassName(mapsPackageName, "com.google.android.maps.MapsActivity");
i.setPackage(mapsPackageName);
}
context.startActivity(i);
private static boolean isPackageExisted(Context context, String targetPackage){
PackageManager pm=context.getPackageManager();
try {
PackageInfo info=pm.getPackageInfo(targetPackage,PackageManager.GET_META_DATA);
} catch (PackageManager.NameNotFoundException e) {
return false;
}
return true;
}

As of 2020 you can also consider using Google Maps URLs, the API designed by Google in order to create universal cross-platform links. You can open Google maps on web, Android or iOS using the same URL string in form:
https://www.google.com/maps/search/?api=1&parameters
In case when you need show certain location you can use an URL like
https://www.google.com/maps/search/?api=1&query=36.26577,-92.54324
The code snippet is
String url = "https://www.google.com/maps/search/?api=1&query="+address;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,Uri.parse(url));
startActivity(intent);

Uri gmmIntentUri = Uri.parse("geo:37.7749,-122.4194");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
startActivity(mapIntent);
}
Refer this documentation

try {
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=" + src_lat+ "," + src_lng + "&daddr=" + des_lat + "," + des_lng));
startActivity(intent);
}catch (ActivityNotFoundException ane){
Toast.makeText(activity, "Please Install Google Maps ", Toast.LENGTH_LONG).show();
}catch (Exception ex){
ex.getMessage();
}
}
});

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("geo:0,0?q=" + address));
startActivity(intent);

This helper method using uriBuilder for cleaner code and handle condition if there is no activity on device that can open map
public static boolean openMap(Context context, String address) {
Uri.Builder uriBuilder = new Uri.Builder()
.scheme("geo")
.path("0,0")
.appendQueryParameter("q", address);
Intent intent = new Intent(Intent.ACTION_VIEW, uriBuilder.build());
if (intent.resolveActivity(context.getPackageManager()) != null) {
context.startActivity(intent);
return true;
}
return false;
}

I find this solution in Google documentation so, it will work fine.
Double latitude = 37.7749,longitude = -122.4192;
String label = "Your location desired Aryan";
Uri gmmIntentUri =
Uri.parse("geo:0,0?q="+latitude+","+longitude+"("+label+")");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
context.startActivity(mapIntent);
If you have any doubt just comment it. I am not checking maps package because on every Android device we have maps. If you want you check it easily.

For the ones, who are looking for opening the "Maps" app for a particular location(by passing lat and long) and do not want that lat/long co-ordinates to be shown in Maps search bar after redirection(Opening Maps app). Instead wish to show some label or place name, you can refer to the code below,
private void openMapView(String latitude , String longitude , String locationName){
Uri gmmIntentUri = Uri.parse("geo:"+latitude+","+longitude+"?q="+locationName);
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(context.getPackageManager()) != null) {
context.startActivity(mapIntent);
}
}
Note : "locationName" in the method above, represents the name you wish to display inside the Maps search bar.

To show location and disply show directions button inside google Maps use
this code snippet:
String geoUri = "http://maps.google.com/maps?q=loc:" + latitude + "," + longitude + " (" + locationName + ")";
Intent mapIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(geoUri));
if (mapIntent.resolveActivity(context.getPackageManager()) != null) {
context.startActivity(mapIntent);

I thought I would chip in with the Kotlin code.
I created a helper function that takes latitude, longitude and context params to fire off the intent.
fun openGoogleMap(latitude: Double, longitude: Double, context: Context) { ... }
Inside the openGoogleMap() helper function create an intent passing in the action, data to act upon (lat/long) and package name for the Google Map application.
fun openGoogleMap(latitude: Double, longitude: Double, context: Context) {
// you need action, data and package name
val uri = Uri.parse("geo:$latitude,$longitude?z=15")
//create an intent
val mapIntent = Intent()
//add action & data
mapIntent.action = Intent.ACTION_VIEW
mapIntent.data = uri
//package name for google maps app
mapIntent.setPackage("com.google.android.apps.maps")
try {
context.startActivity(mapIntent)
} catch (e: ActivityNotFoundException) {
//if map app isn't resolved/installed catch error
e.printStackTrace()
}
}
The docs say that
To verify that an app is available to receive the intent, call
resolveActivity() on your Intent object. If the result is non-null,
there is at least one app that can handle the intent and it's safe to
call startActivity().
But I found that using resolveActivity() has issues when used with this code especially when you are outside the Activity's code.
mapIntent.resolveActivity(packageManager)?.let {
...
}
To get around this I used try-catch block to catch ActivityNotFoundException with startActivity().
mapIntent.setPackage("com.google.android.apps.maps")
try {
context.startActivity(mapIntent)
} catch (e: ActivityNotFoundException) {
//if map app isn't resolved/installed catch error
e.printStackTrace()
}
I tested the util function and it does work and is launching the GoogleMaps with Kotlin code.

If you have the name and address of the location available then you can launch the exact spot along with its images, details and navigation option using the following code :
fun loadLocation(ctx: Context, name: String, address: String) {
try {
val geoUri = "http://maps.google.com/maps?q=$name,$address"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(geoUri))
ctx.startActivity(intent)
}
catch (ex: Exception) {
ex.printStackTrace()
}
}

https://www.google.com/maps/dir//37.4219983,-122.084
String location = "https://www.google.com/maps/dir//" + latitude + "," + longitude;
try {
SmsManager sms = SmsManager.getDefault(); // using android SmsManager
sms.sendTextMessage(number, null, message + location, null, null); // adding number and text
Toast.makeText(getApplicationContext(), "Message Sent", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(this, "Sms not send, please check phone number/network", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}

Google Maps 7 started with geo intent is dropping a pin at the closest address to a coordinate instead of the exact location

In my app users can save the latitude and longitude of a particular location. I want them to able to launch other apps on their phone via a geo intent such as Google Maps so that they can easily get exact directions back to it. Here is the code I am using to generate the geo intent:
public static Intent getFindIntent(Context context) {
Intent intent = new Intent();
SharedPreferences prefs = Tools.getPrefs(context);
String latitude = prefs.getString(Const.LAT_KEY, "");
String longitude = prefs.getString(Const.LONG_KEY, "");
intent.setAction(Intent.ACTION_VIEW);
String uri = String.format(Locale.US, "geo:%s,%s?z=%d&q=%s,%s", latitude, longitude,
Const.ZOOM_LEVEL, latitude, longitude);
intent.setData(Uri.parse(uri));
return intent;
}
Obviously most people will use Google Maps since it's on everyone's phone. When I first released my application Google Maps would start and drop a pin at the exact coordinates specified in the q parameter of the geo uri that is set as data for the intent. With the release of Google Maps 7, maps seems to drop a pin at the closest address to the provided coordinates. This poses a problem to me since users should be able to navigate back to the saved position exactly, and not an address near it. The only place I have found this documented is here. The docs are from the official Android Developer site but they are very sparse. Are there alternatives to the geo intent to provide this functionality or is there something wrong with my code? I think Google Maps is breaking it's API contract since I am providing coordinates and not an address.

To drop the pin use this code:
try {
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:" + AppointmentDetailLayout.docLatitude
+ "," + AppointmentDetailLayout.docLongitude
+ "?q=" + AppointmentDetailLayout.docLatitude
+ "," + AppointmentDetailLayout.docLongitude
+ "(" + label + ")"));
intent.setComponent(new ComponentName(
"com.google.android.apps.maps",
"com.google.android.maps.MapsActivity"));
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
try {
context.startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse("market://details?id=com.google.android.apps.maps")));
} catch (android.content.ActivityNotFoundException anfe) {
context.startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/apps/details?id=com.google.android.apps.maps")));
}
e.printStackTrace();
}
For directions use this :
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=" + lat
+ "," + lng + "&daddr="
+ AppointmentDetailLayout.docLatitude + ","
+ AppointmentDetailLayout.docLongitude));
context.startActivity(intent);

Search nearby hospital via google map intent (Android)

I need to search nearby child hospital and find the root from button click using intent,
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?&saddr="
+ x
+ ","
+ y
+ "&daddr=nearby child hospitals"
));
startActivity(intent);
x,y as current lat and long.
It will show the hospitals are not in my current location(Shows different country hospitals)
Then, I click back button, then click Get Directions button means (From text box contains my source lat and long, Destinations text box contains nearby child hospitals), it shows my nearer child hospitals.
Is there any way do to this in first (i.e., intent call)?

You can use "geo:" URL scheme to open maps and then search nearby hospitals like this:
String uri = "geo:"+ x + "," + y +"&q=child hospitals";
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
For documentation reference, see Invoking Google Applications on Android Devices

Uri gmmIntentUri = Uri.parse("geo:0,0?q=" + query);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(gmmIntentUri.toString()));
intent.setPackage("com.google.android.apps.maps");
try {
context.startActivity(intent);
} catch (ActivityNotFoundException ex) {
try {
Intent unrestrictedIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(gmmIntentUri.toString()));
context.startActivity(unrestrictedIntent);
} catch (ActivityNotFoundException innerEx) {
Toast.makeText(context, "Please install a maps application", Toast.LENGTH_LONG).show();
}
}

you can use this code, intent open a map and automatic search hospital near me
String uri = "geo:"+ x + "," + y +"?q=hospitals+near+me";
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
