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

Answer 1

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&origin=81.23444,67.0000&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);

Answer 2

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 + "&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"

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);
    }
