How do I open google maps app on tapping an address?

I have an address param within my app say " 921 Beverly Hills, california, CA- 09001"
Upon tapping this I want google maps to open and show annotation for this exact address. How do I do that?
Any clue?

launch maps
There are great resources to get you going this is a sample. In a real app you would want to handle the intent with your own map activity; maybe add bounds and a camera to zoom in or whatever...
Location sf = new Location("");
sf.setLatitude(37.7749);
sf.setLongitude(-122.4194);
requestLocation("your address");
public void requestLocation(Location location) {
// Create a Uri from an intent string. Use the result to
// create an Intent.
Uri gmmIntentUri = Uri.parse("geo:" + location.getLatitude() + "," + location.getLongitude());
// Create an Intent from gmmIntentUri. Set the action to
// ACTION_VIEW
Intent mapIntent = new Intent(Intent.ACTION_VIEW,
gmmIntentUri);
// Make the Intent explicit by setting the Google Maps
// package
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(mapIntent, REQUEST_LOCATION);
}
}
public void requestLocation(String address) {
// Create a Uri from an intent string. Use the result to create
//an Intent.
Uri gmmIntentUri = Uri.parse("geo:" + address);
// Make the Intent explicit by setting the Google Maps
// package
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(mapIntent, REQUEST_LOCATION);
}
}

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);

google maps application from my application wid a label over the location

I can open google maps from my application and have a pointer over the location i am pointing to.
Instead i wanted to open google maps application from my application---- as is when user clicks on an address google maps application opens up with that particular point.
for that i used
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("geo:lat,lng?q=lat,lng")));
Here lat=34.456373 and lng=-45.464748
Google maps application is opening but that particular location is not coming up instead my present location is coming up.How to rectify that?

String geoCode = "geo:0,0?q=" + PLACE_LATITUDE + ","+ PLACE_LONGITUDE + "(" + PLACE_NAME + ")";
Intent sendLocationToMap = new Intent(Intent.ACTION_VIEW,
Uri.parse(geoCode));
startActivity(sendLocationToMap);
http://developer.android.com/guide/appendix/g-app-intents.html refer for more detail..

String uri = String.format("geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);
see if this helps.

lat.setText(String.valueOf(latitude));
lon.setText(String.valueOf(longitude));
String showMap = String.valueOf(latitude) + ","
+ String.valueOf(longitude);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("geo:0,0?q=" + (showMap)));
try {
startActivity(intent);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error in gps "+e, Toast.LENGTH_LONG).show();
}

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)));
