I wonder if it possible to retrieve the Google Maps navigation history. In other words, is there a way of retrieving the recent routes taken/searched by the user of the Google Maps app?
Thanks
You can not finish Google Navigation App.
There is only one work around which I found,
Re-start the navigation with the current location, hence the navigation will automatically be finished.
public static void startNavigationIntent(Context activity, String destination)
{
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("google.navigation:q=" + destination));
activity.startActivity(intent);
}
And then bring your app to the foreground.
Intent bringToForegroundIntent = new Intent(BackgroundLocationService.this, DashboardActivity.class);
bringToForegroundIntent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(bringToForegroundIntent);
There is no API available to get information out of the Navigation App. But you can feed some data to Maps to request a route through an Intent / URI.
But I don't think that the Maps app will save the whole route anyway, only the destination. The user selects any saved destination and you can get there from any source.

I have an app that makes use of the following intent in order to display a set of places on Google Map and start direction based on user choice:
Intent intent =
new Intent(Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=" + Uri.encode("mykeyword") + "&z=14"));
// force to use Google maps
intent.setClassName(
"com.google.android.apps.maps",
"com.google.android.maps.MapsActivity");
The intent is started as follows:
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.apps.maps")));
}
The code is triggered by my app activity that is displayed on the lock screen (thanks to the android:showOnLockScreen="true" property). It means the device is locked when the intent is used.
Unfortunately, the intent requires the user to unlock the device in order to have access to the Google Map activity.
I am looking for a way to display the Activity associated with the intent without having the user to unlock his/her device.
The only solution I have for now is to reimplement what is done by the com.google.android.maps.MapsActivity in my own activity. Unfortunately, this is a lot of work just to mimic what is done with the existing Google Map intent (i.e. displaying places for a given keyword, offering a field to change the keyword, displaying suggestions list, detail view, and direction, etc. all with a good UX).
Any experiences or ideas with such a scenario are welcome.
What I got is that you want to use your app whether screen is lock or unlock like Google Map Navigation, right?
I want to open google maps turn by turn direction screen on button click and want to check if user reaches the destination redirect the user to my app currently i am using this code to open google maps
String uri = String.format(Locale.ENGLISH, "geo:0,0?q="+ destinationLoc.latitude+","+destinationLoc.longitude
+ "(The Embroidery Store)" );
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
I want to redirect the user to my app after he reaches the destination.
You may want to look into the concept of geo-fencing.

I am building an android application, that will show certain points on google maps, for which I have (lat,lang) for all the points shown, with me. Whenever, a user clicks on one of these locations on google maps, I am starting a new Google Maps intent which shows navigation to the user and is supposed to take the user to that (lat, lang).
//suppose this function is called on onclick of google maps event
function onclick(){
Uri gmmIntentUri = Uri.parse("google.navigation:q=32.885240,-96.763475");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
startActivity(mapIntent);
}
}
This will start the navigation for the user.
Now what I want to achieve is this -
Whenever this navigation is complete, I want some kind of flag to be passed to my android application, so that my application knows that the navigation has been finished.
If it is possible to automatically close the google maps application after the navigation has been completed, it will be nice to have.
Any help is greatly appreciated. Thanks. Anyone has any solutions for this?
You need to call the finish() method on the activity when the destination is reached. So here are the steps that you need to implement in your program.
First of all know the destination coordinates from the user input and pass it in the Direction API.
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&key=API_KEY
When you know the destination coordinates you can pass that when the marker representing that is clicked in the navigation intent. (which you have already done)
Make use of the location listener interface that tracks the current location coordinates.
Put an if...else condition where you check that the current location is equivalent to the destination.
When the current location == Destination make a call to activity.finish() which will finally close the maps activity hosting.
Hope that Helps!!
I am launching Google Navigation with intent:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?daddr=" + mCity));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);
It build route from my current location to destination city. But sometimes it give me few routes. Is there way to force give me always only one route?
It is just launching Google Navigation app with destination and current address, so it will depend on user to choose one route as is case with regular navigation app.
How can i start an Intent to open either the default navigation application (e.g. Google Navigation or Google Maps) or give the user the opportunity to select among navigation applications.
Thanks in advance.
You have to use an Intent with ACTION_VIEW and the geo data scheme.
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 latitude and longitude parameters.
I found a way to center the map with latitude and longitude 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);
This intent is from the list of official "G apps" intent list here.
Try:
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=New+York+NY")); startActivity(i);
Or use this, this way the stardard navigation app will be launched:
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345"));
startActivity(intent);
Add this line before startActivity if you don't want the popup dialog:
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
