The Mapbox Maps SDK for Android provides several different ways to mark a single point, add a line between many points, or draw a polygon. Often, these objects are drawn either on top of the map or in some cases, within the map itself. This document walks you through how to add high-level objects. If you'd like more control over annotations, make sure to check out the runtime styling documentation.


Markers are useful when identifying a single point on the map. The SDK comes with a default marker icon which can be configured to fit your specific needs. APIs are exposed to optionally change this icon to any bitmap image you wish. To create a marker for you map, you are only required to provide a LatLng position which defines where the marker will be placed on the map. Call mapboxMap.addMarker() to actually add the marker to the map.

mapboxMap.addMarker(new MarkerOptions()
.position(new LatLng(48.85819, 2.29458))
.title("Eiffel Tower")

Besides providing the position, you can also add a title and snippet which display inside of an info window. The info window is displayed when users tap on the marker and close when they tap outside of the info window.

Add a list of markers using mapboxMap.addMarkers() if you have many markers or are loading them from a GeoJSON file.

Removing markers

The Mapbox Android SDK comes with two methods for removing markers. If you'd like to remove a particular marker, use mapboxMap.removeMarker() while passing in the marker object to be removed. If you would like to remove all markers, call the mapboxMap.clear() method. Note that this will also remove any polylines and polygons you’ve added to your map.

Customize marker icon

You can specify a custom icon by using the IconFactory object and passing it to the marker. The default marker icon's used if you don’t specify an icon while creating your marker. The anchoring of the marker will be in the center, meaning if you have an icon with a point, you'll need to add padding to the bottom of the image.

Place your custom marker image in your project’s drawable folder and note its file name. In the example below, the custom icon’s image file's called blue_marker.png

// Create an Icon object for the marker to use
IconFactory iconFactory = IconFactory.getInstance(MainActivity.this);
Icon icon = iconFactory.fromResource(R.drawable.blue_marker);
// Add the marker to the map
mapboxMap.addMarker(new MarkerViewOptions()
.position(new LatLng(-37.821648, 144.978594))

Capturing marker events

The Mapbox Maps SDK for Android provides a handy listener for capturing when a user taps on a marker. By default, all markers come with an onMarkerClick event listener for displaying and hiding info windows. You can override this default event listener and set your own with the setOnMarkerClickListener method.

To display a toast message with the clicked marker’s title, listen for a click event with setOnMarkerClickListener and finally call Toast.makeText(). To prevent displaying a toast message and an info window at the same time, return true at the end:

mapboxMap.setOnMarkerClickListener(new MapboxMap.OnMarkerClickListener() {
public boolean onMarkerClick(@NonNull Marker marker) {
Toast.makeText(MainActivity.this, marker.getTitle(), Toast.LENGTH_LONG).show();
return true;

Update a marker

If you have intentions to update a marker rather than completely removing it, the SDK provides a few update methods. Using these mean less boilerplate code and an increase in performance since you are only updating the marker. Using these update APIs, you can create animating markers using a ValueAnimator for example. The APIs for updating either the marker position or icon bitmap are found inside of your marker object reference.

// Change the marker location
marker.setPosition(new LatLng(-37.822884, 144.981916));
// Update the marker icon

Info window

Info windows are used to display information in a popup window anchored to a marker. Their default behavior is to appear when the marker is tapped and then show a title text view above a snippet text view. An info window gets created if you provide a given marker with either a title or a snippet of text. If you need to add an info window at a later time or need to update the title, for example, use marker.setTitle().

Custom view

The Maps SDK also provides an API to customize the contents and design of info windows. You'll need to create an implementation of the InfoWindowAdapter and then call MapboxMap.setInfoWindowAdapter() and pass in your implementation as a parameter. Inside the InfoWindowAdapter, a method called getInfoWindow gives the attached marker object and returns the info window view.

Polyline and polygons

Adding a line or polygon to your map is like adding a marker. Due to the nature of these objects, different APIs are exposed, such as polygon color or line width. Instead of taking in a single position, bundle all your LatLng's inside a List and then pass them in using the addAll() API.

// Draw polyline on the map
mapboxMap.addPolyline(new PolylineOptions()
// Draw a polygon on the map
mapboxMap.addPolygon(new PolygonOptions()
