Mappedin Android SDK release notes are posted here and this page will be kept up-to-date as updates are released.

August 24, 2021

Update dependency in build.gradle to version 3.0.5: implementation 'com.mappedin.sdk:mappedin:3.0.5'

  • Bumped minSdkVersion to 21 (Android 5.0)
  • Security bug fixes
  • labelAllLocations bug fix

August 16, 2021

Update dependency in build.gradle to version 3.0.4: implementation 'com.mappedin.sdk:mappedin:3.0.4'

  • Performance improvements

July 22, 2021

Update dependency in build.gradle to version 3.0.3: implementation 'com.mappedin.sdk:mappedin:3.0.3'

  • Label performance improvements: Some issues affecting the speed of rendering labels on the map have been fixed. This can lead to improved load times when rendering labels on map initialization, especially when smart labels are enabled.

June 24, 2021

Update dependency in build.gradle to version 3.0.2: implementation 'com.mappedin.sdk:mappedin:3.0.2'

Label rankings

Polygons now have a rank property representing that polygon’s label display priority. This data is also accessible in the MPIData object made available in onDataLoaded. ​

fun onDataLoaded(data: MPIData) {
val rankings: MPIRankings? = data.rankings
val polygonRank = data.polygons.first().rank

Label styling

Labels now have an appearance property, a LabelAppearance which controls the display of that label. New appearance options are available, and the previous style properties on the label itself are now considered deprecated. ​

val label = MPIOptions.Label(

​ The following appearance options are available:

margin: Double,
text: {
numLines: Int,
size: Double,
maxWidth: Double,
foregroundColor: String,
backgroundColor: String
marker: {
size: Double,
foreGroundColor: {
active: String,
inactive: String
backgroundColor: {
active: String,
inactive: String

Multi-destination navigation

The APIs to get directions and to draw a journey on the map now support multiple destinations, via the MPIDestinationSet class. There is a new journeyManager property on the mapView with functions to draw a journey, clear the current journey, and setStep on the current journey if it’s multi-destination. The drawJourney and clearJourney methods of mapView are now considered deprecated. ​

val multiDirections: List<MPIDirections> = mapView.getDirections(
to=MPIDestinationSet(listOf(aNode, anotherLocation)),
) {

May 27, 2021

This release contains support for adjusting aspects of the camera that is used to render the mapView.

Android Update to 3.0.1 production release: implementation 'com.mappedin.sdk:mappedin:3.0.1'

Camera controls mapView now contains another class, CameraControlsManager, that allows the user to query and manipulate some aspects of the camera that is used to render the map. You can get and set the rotation and tilt of the camera:

mapView?.cameraControlsManager.setRotation(rotation: 180) mapView?.cameraControlsManager.setTilt(tilt: 0.3) mapView?.cameraControlsManager.rotation mapView?.cameraControlsManager.tilt

Rotation is measured in degrees relative to north- setting it to 0 will orient the map so north points upward. Tilt is measured in radians relative to top-down- setting it to 0 will result in a top-down view, while setting it to 0.1 will apply a slight tilt.

May 15, 2021

Android SDK 3.0.0-beta-11 release resolves a bug with the marker anchor where regardless of passing any Anchor using MPIOptions, the pin stayed in the same location.

April 26, 2021

This release contains support for custom blueDot color, error handling in mapView.showVenue, no valid path for instructions in mapView.getDirections and new blueDot callbacks.


Update to 3.0.0-beta-10 in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-10'

Sample code examples can be found here for Android

Custom Blue Dot Color

mapView.enableBlueDot still takes in MPIOptions.BlueDot as a parameter. MPIOptions.BlueDot still takes in allowImplicitFloorLevel, smoothing, and showBearing as before. In addition, you can now also pass in a string baseColor in MPIOptions.BlueDot that allows you to set the color of your blueDot. baseColor supports strings like "red", "green", …, or colors in hex code such as "#7851a9". baseColor is an optional parameter, and the default color is set to be the original blue dot color, "#2266ff".

  1. mapView?.enableBlueDot(MPIOptions.BlueDot(allowImplicitFloorLevel: true, smoothing: false, showBearing: true, baseColor: "green"))
  2. mapView?.enableBlueDot(MPIOptions.BlueDot(allowImplicitFloorLevel: true, smoothing: false, showBearing: true, baseColor: "#7851a9"))

MPIInstruction For No Valid Path

When calling mapView.getDirections between two MPINavigatables (MPINode, MPILocation, MPIPolygon) and there exists no valid path between them, the instruction string of the first instruction in the directionsCallback will state “No Valid Path Available” and the distance double will contain 0.0.

Error Handling For ShowVenue

mapView.showVenue still takes in a data string or a deserialized MPIVenueResponse and MPIOptions.ShowVenue as before. In addition, it has an optional error callback errorCallback that allows you to check if mapView.showVenue has an error. The error callback contains an MPIError enum which is either null (no error), MPIError.SHOW_VENUE (error showing the venue) or MPIError.DECODE (error decoding the data). This error callback is optional, so nothing needs to be added if you do not want an error callback.

An example is shown below:

"<venue data string>",
labelAllLocationsOnInit = true,
backgroundColor = "#CDCDCD"
) { it?.let { //error callback

New Blue Dot Callbacks

BlueDot updates have now been split into two separate callbacks. Previously, the only callback was onBlueDotUpdated and currently, the two callbacks are onBlueDotPositionUpdate and onBlueDotStateChange

The onBlueDotPositionUpdate callback takes in an MPIBlueDotPositionUpdate parameter which is nearly identical to the MPIBlueDot class, except MPIBlueDotPositionUpdate contains a newly added Double? variable bearing. You can still expect the same behaviour for the other class variables in MPIBlueDotPositionUpdate --- position (MPIPosition?), map (MPIMap?), nearestNode (MPINode?).

The onBlueDotStateChange callback takes in an MPIBlueDotStateChange parameter which has four class variables --- name (MPIBlueDotState), markerVisibility (MPIMarkerState?), reason (MPIBlueDotStateReason?), and message (String?). These four variables introduce different properties about the current state of the blueDot. The enums have following possible values:


Message is an optional string that is used for the WebSDK and basically adds additional non-enum messages to developers about why things may fail. But it is not relevant for the Android/iOS SDKs. 

Changes you should make in your app to adopt the new blue dot event:

  1. You should add two additional callbacks (onBlueDotPositionUpdate and onBlueDotStateChange) inside classes that conform to MPIMapViewListener.
  2. MPIBlueDot is now a deprecated class and should be replaced with MPIBlueDotPositionUpdate. onBlueDotUpdated is also a deprecated callback and should not be used. Instead, you should only use the callbacks explained above.
  3. For everything you initially had in onBlueDotUpdated, you should also make your changes accordingly to include them inside the two new callbacks. The sample code includes an example of this: make the global variable blueDot an MPIBlueDotPositionUpdate, update the global variable blueDot and nearestNode.text inside onBlueDotPositionUpdate instead.

April 13, 2021

This release contains support for creating and removing custom markers, MPIOptions.Journey has increased customization and distance has been added as a property on MPIInstruction.MPIMap.createCoordinate can be used to create a MPICoordinate by passing in latitude and longitude values.


Update to 3.0.0-beta-9 in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-9'

Sample code examples can be found here for Android

Custom Markers

Markers can be created and removed using createMarker and removeMarker which are member functions of the MPIMapView class. createMarker takes in three parameters. Firstly, createMarker takes in an MPINavigatable.MPINode which the marker will be displayed on. Secondly, the function takes in a string of HTML code which will generate the appearance of the marker. Lastly, createMarker takes in options in the form of an MPIOptions.Marker object, which includes a rank (optional) and an anchor (optional). While rank is simply double, the anchor option is a MARKER_ANCHOR enum and contains values for CENTER, TOP, BOTTOM, LEFT, and RIGHT. When createMarker is called, the third parameter defaults to an empty MPIOptions.Marker object. createMarker returns a unique id string for the marker, which can later be used to remove the marker. Two code examples of creating a marker are as follows:

mapView.createMarker(polygon.entrances[0], "<div>marker1</div>")

id2 = mapView.createMarker(polygon.entrances[0], "<div>marker2</div>", MPIOptions.Marker(1.0, MPIOptions.MARKER_ANCHOR.LEFT))

removeMarker takes in only the id of the marker to be removed. A code example of removing a marker is as follows: mapView.removeMarker(id2)

Markers are also compatible with smartLabels and will replace labels when being generated. Additionally, once a marker is removed, the smartLabel will be displayed once again.

Update to drawJourney Options

mapView.drawJourney still takes in an MPIDirections object and MPIOptions.Journey object as before. MPIOptions.Journey object can still take in a connectionTemplateString and pathOptions. In addition, you can now also pass in a destinationMarkerTemplateString, departureMarkerTemplateString, and polygonHighlightColor to MPIOptions.Journey. By default, when you call drawJourney, a predetermined destination and departure marker appear on the last and first nodes, respectively, from MPIDirections.Path. The same behaviour occurs if you pass null for both destinationMarkerTemplateString and departureMarkerTemplateString. You can also set destination and departure markers to not show up by passing in an empty string for both destinationMarkerTemplateString and departureMarkerTemplateString. If you want to create custom destination and departure markers, you can pass in your own custom string of HTML code. You can now also pass a polygonHighlightColor string in MPIOptions.Journey to change the highlighted color of the destination and departure polygons.

See the code block below some code examples for the features mentioned above: 

directions = directions,
options = MPIOptions.Journey(
connectionTemplateString = "<div style=\"font-size: 13px;display: flex; align-items: center; justify-content: center;\"><div style=\"margin: 10px;\">{{capitalize type}} {{#if isEntering}}to{{else}}from{{/if}} {{toMapName}}</div><div style=\"width: 40px; height: 40px; border-radius: 50%;background: green;display: flex;align-items: center;margin: 5px;margin-left: 0px;justify-content: center;\"><svg height=\"16\" viewBox=\"0 0 36 36\" width=\"16\"><g fill=\"white\">{{{icon}}}</g></svg></div></div>",
destinationMarkerTemplateString = null,
departureMarkerTemplateString = "<div>departureMarker</div>",
pathOptions = MPIOptions.Path(
color = "#cdcdcd",
pulseColor = "#000000",
displayArrowsOnPath = true
polygonHighlightColor = "orange"

Distance in Instructions

MPIInstruction now contains a distance parameter which is the distance of the MPIAction in meters.

Coordinate from Latitude/Longitude

To get the coordinate, createCoordinate can be used. This function is a member of the MPIMap class. By passing in latitude and longitude values, createCoordinate returns an MPICoordinate object containing an x and y value, the latitude and longitude parameters, and the MPIMap itself. x and y values are scaled to Mappedin units & latitude and longitude represent real world units.

March 28, 2021

This release contains updates to display the venue by passing in data as MPIVenueResponse or the string of the response from the legacy exporter service to the showVenue method. Additionally, the type property on MPIVortex has been changed to be an enum instead of a string.


Update to 3.0.0-beta-8 in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-8'


This is an alternative method to using loadVenue where no API calls will be made to retrieve the data. Instead, the data must be passed into the showVenue method which takes in a data string or a deserialized MPIVenueResponse and MPIOptions.ShowVenue.

Sample code examples can be found here:

Reading MPIData from MPIVenueResponse

This response can be converted into an MPIData object where Mappedin data can be read before displaying the venue by calling the static method fromVenueResponse on MPIData and passing in the venue data string or MPIVenueResponse Object. val data = MPIData.Companion.fromVenueResponse(venueDataJson)

February 28, 2021

This release contains updates on the bluedot by adding follow state, option to disable smoothing and showBearing, and a method for finding the nearest node based on screen coordinates.


Update to 3.0.0-beta-6 in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-6'

Follow Mode

The MPIMapViewListener now has a new method called onStateChanged(:MPIState) that is triggered when the state of the map changes. Call mapView?.setState(MPIState.FOLLOW) will set the map to follow the BlueDot (the screen will move to follow the bluedot and will change map to the correct floor. Map interactions will remove the user from this state (pan, zoom) and set the state to MPIState.EXPLORE

Bluedot Options

Pass showBearing as true in MPIOptions.BlueDot when calling enableBlueDot to show bearing. Pass smoothing as false in MPIOptions.BlueDot when calling enableBlueDot to disable our smoothing algorithm.

Get Nearest Node By Screen Coordinates

Android Example to get nearest node from center of the screen (see full source code in

mapView?.width?.div(2) ?: 0,
mapView?.height?.div(2) ?: 0


focusOn can now properly focus on nodes passed in from locations

February 15, 2021

This release contains updates to navigation, adds custom headers and options when showing the venue. To update, follow the instructions for each platform:

Data Changes


directions property has been renamed to instructions, please update this in your app if you are accessing the directions property.

Additionally, atVortex has been added to MPIInstruction, if a vortex is available at that instruction. 


Update to 3.0.0-beta-4 in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-4'

Update in your gradle file implementation 'com.mappedin.sdk:mappedin:3.0.0-beta-4'


To use bluedot, first enable it by calling enableBlueDot(), and then call updatePosition(:MPIPosition)

//Call this whenever GPS or beacon location provider updates user position`

Navigation w/ Connection Markers

You can now draw a journey instead of just a path with the drawJourney method which takes in an MPIDirections object. This will draw the path and connection markers if the journey is multi-floor.

mapView.getDirections(selectedPolygon!!, blueDot?.nearestNode!!, true) { directions ->
directions?.path?.let { path ->

To get text for directions, after calling getDirections with two MPINavigatables (MPINode, MPILocation, MPIPolygon) as the to and from parameters, you should receive an MPIDirections object in the callback. The instructions will be accessible in the instructions property which is a list of MPIInstructions which contains an instruction property which is a String that contains the text for the instruction.

Custom Navigation Markers

If you want custom navigation markers, you can pass in a connectionTemplateString in the MPIOptions.Journey. This is an html template, you can pass it in as seen below:

connectionTemplateString = """
<div style=\"font-size: 13px;display: flex; align-items: center; justify-content: center;\">
<div style=\"margin: 10px;\">
{{capitalize type}} {{#if isEntering}}to{{else}}from{{/if}} {{toMapName}}
<div style=\"width: 40px; height: 40px; border-radius: 50%;background: green;display: flex;align-items: center;margin: 5px;margin-left: 0px;justify-content: center;\">
<svg height=\"16\" viewBox=\"0 0 36 36\" width=\"16\">
<g fill=\"white\">{{{icon}}}</g>
pathOptions = MPIOptions.Path(
drawDuration = 0.0,
pulseIterations = 0.0

You can use the template above and change the background color under background: green or pass in your own template string.

Custom Headers

Headers can now be added for each request when loading the venue

mapView.loadVenue(MPIOptions.Init(headers=listOf(MPIHeader("testName", "testValue"))))

Show Venue Options

You can also now pass in an MPIOptions.ShowVenue on loadVenue to modify the properties of the map on the first load, the following properties are supported firstMapId, labelAllLocationsOnInit, backgroundColor, backgroundAlpha

labelAllLocationsOnInit = false,
firstMapId = "55e9c73fd982bc3839000003",
backgroundColor = "#CDCDCD"
