Launching Google Maps Directions via an intent on Android

Question

My app needs to show Google Maps directions from A to B  but I don t want to put the Google Maps into my application - instead  I want to launch it using an Intent  Is this possible  If yes  how

This is a little off-topic because you asked for "directions", but you can also use the Geo URI scheme described in the Android Documentation:

http://developer.android.com/guide/appendix/g-app-intents.html

The problem using "geo:latitude,longitude" is that Google Maps only centers at your point, without any pin or label.

That's quite confusing, especially if you need to point to a precise place or/and ask for directions.

If you use the query parameter "geo:lat,lon?q=name" in order to label your geopoint, it uses the query for search and dismiss the lat/lon parameters.

I found a way to center the map with lat/lon and display a pin with a custom label, very nice to display and useful when asking for directions or any other action:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("geo:0,0?q=37.423156,-122.084917 (" + name + ")"));
startActivity(intent);

NOTE (by @TheNail): Not working in Maps v.7 (latest version at the time of writing). Will ignore the coordinates and search for an object with the given name between the parentheses. See also Intent for Google Maps 7.0.0 with location

if you know point A  point B  and whatever features or tracks in between  you can use a KML file along with your intent   String kmlWebAddress    http   www afischer-online de sos AFTrack tracks e1 01 24 Soltau2Wietzendorf kml   String uri   String format Locale ENGLISH   geo 0 0 q  s  kmlWebAddress   Intent intent   new Intent Intent ACTION VIEW  Uri parse uri    startActivity intent     for more info  see this SO answer  NOTE  this example uses a sample file that  as of mar13  is still online   if it has gone offline  find a kml file online and change your url

You could use something like this   Intent intent   new Intent android content Intent ACTION VIEW       Uri parse  http   maps google com maps saddr 20 344 34 34 amp daddr 20 5666 45 345     startActivity intent     To start the navigation from the current location  remove the saddr parameter and value   You can use an actual street address instead of latitude and longitude  However this will give the user a dialog to choose between opening it via browser or Google Maps   This will fire up Google Maps in navigation mode directly   Intent intent   new Intent android content Intent ACTION VIEW      Uri parse  google navigation q an address city       UPDATE  In May 2017 Google launched the new API for universal  cross-platform Google Maps URLs   https   developers google com maps documentation urls guide  You can use Intents with the new API as well

A nice kotlin solution  using the latest cross-platform answer mentioned by lakshman sai     No unnecessary Uri toString and the Uri parse though  this answer clean and minimal    val intentUri   Uri Builder   apply         scheme  https         authority  www google com         appendPath  maps         appendPath  dir         appendPath           appendQueryParameter  api    1         appendQueryParameter  destination      yourLocation latitude    yourLocation longitude       build    startActivity Intent Intent ACTION VIEW  apply         data   intentUri

First you need to now that you can use the implicit intent  android documentation provide us with a very detailed common intents  for implementing the map intent you need to create a new intent with two parameters   Action  Uri   For action we can use Intent ACTION VIEW  and for Uri we should Build it  below i attached  a sample code to create build start the activity    String addressString    1600 Amphitheatre Parkway  CA               Build the uri              Uri Builder builder   new Uri Builder        builder scheme  geo                path  0 0                query addressString       Uri addressUri   builder build               Intent to open the map             Intent intent   new Intent Intent ACTION VIEW  addressUri               verify if the devise can launch the map intent             if  intent resolveActivity getPackageManager       null                     launch the intent                    startActivity intent

Open Google Maps using Intent with different Modes   We can open Google Maps app using intent   val gmmIntentUri   Uri parse  google navigation q   destintationLatitude     destintationLongitude     amp mode b   val mapIntent   Intent Intent ACTION VIEW  gmmIntentUri  mapIntent setPackage  com google android apps maps   startActivity mapIntent    Here   mode b  is for bicycle   We can set driving  walking  and bicycling mode by using    d for driving  w for walking  b for bicycling   You can find more about intent with google maps here   Note  If there is no route for the bicycle car walk then it will show you  Can t find the way there   You can check my original answer here

Although the current answers are great  none of them did quite what I was looking for  I wanted to open the maps app only  add a name for each of the source location and destination  using the geo URI scheme wouldn t work for me at all and the maps web link didn t have labels so I came up with this solution  which is essentially an amalgamation of the other solutions and comments made here  hopefully it s helpful to others viewing this question   String uri   String format Locale ENGLISH   http   maps google com maps saddr  f  f  s  amp daddr  f  f   s    sourceLatitude  sourceLongitude   Home Sweet Home   destinationLatitude  destinationLongitude   Where the party is at    Intent intent   new Intent Intent ACTION VIEW  Uri parse uri    intent setPackage  com google android apps maps    startActivity intent     To use your current location as the starting point  unfortunately I haven t found a way to label the current location  then use the following  String uri   String format Locale ENGLISH   http   maps google com maps daddr  f  f   s    destinationLatitude  destinationLongitude   Where the party is at    Intent intent   new Intent Intent ACTION VIEW  Uri parse uri    intent setPackage  com google android apps maps    startActivity intent     For completeness  if the user doesn t have the maps app installed then it s going to be a good idea to catch the ActivityNotFoundException  then we can start the activity again without the maps app restriction  we can be pretty sure that we will never get to the Toast at the end since an internet browser is a valid application to launch this url scheme too           String uri   String format Locale ENGLISH   http   maps google com maps daddr  f  f   s    12f  2f   Where the party is at            Intent intent   new Intent Intent ACTION VIEW  Uri parse uri            intent setPackage  com google android apps maps            try                       startActivity intent                     catch ActivityNotFoundException ex                        try                               Intent unrestrictedIntent   new Intent Intent ACTION VIEW  Uri parse uri                    startActivity unrestrictedIntent                             catch ActivityNotFoundException innerEx                                Toast makeText this   Please install a maps application   Toast LENGTH LONG  show                              P S  Any latitudes or longitudes used in my example are not representative of my location  any likeness to a true location is pure coincidence  aka I m not from Africa  P  EDIT   For directions  a navigation intent is now supported with google navigation  Uri navigationIntentUri   Uri parse  google navigation q     12f        2f    creating intent with latlng Intent mapIntent   new Intent Intent ACTION VIEW  navigationIntentUri   mapIntent setPackage  com google android apps maps    startActivity mapIntent

Using the latest cross-platform Google Maps URLs  Even if google maps app is missing it will open in browser  Example https   www google com maps dir  api 1 amp origin 81 23444 67 0000 amp destination 80 252059 13 060604  Uri Builder builder   new Uri Builder    builder scheme  https        authority  www google com        appendPath  maps        appendPath  dir        appendPath          appendQueryParameter  api    1        appendQueryParameter  destination   80 00023         13 0783   String url   builder build   toString    Log d  Directions   url   Intent i   new Intent Intent ACTION VIEW   i setData Uri parse url    startActivity i

For multiple way points  following can be used as well   Intent intent   new Intent android content Intent ACTION VIEW       Uri parse  https   www google com maps dir 48 8276261 2 3350114 48 8476794 2 340595 48 8550395 2 300022 48 8417122 2 3028844     startActivity intent     First set of coordinates are your starting location  All of the next are way points  plotted route goes through   Just keep adding way points by concating   latitude longitude  at the end  There is apparently a limit of 23 way points according to google docs  Not sure if that applies to Android too
