This document describes how to integrate the Kakao Navi API into your service with the Kakao SDK for Android (hereinafter referred to as 'Android SDK').

Before you begin

Add modules

To use the features of Kakao Navi, you need to add v2-navi (Kakao Navi module) that provides NaviClient to the module-level build.gradle file by referring to Add modules. Because the ReactiveX Android SDK does not provide the Kakao Navi API, you must use the Kakao Navi module that the Android SDK provides.

Check if Kakao Navi is installed

The Kakao Navi API provides the navigateIntent() function for navigation and the shareDestinationIntent() function for location sharing.

navigateIntent() and shareDestinationIntent() return Intent to invoke the navigation and location sharing function via the Kakao Navi app (hereinafter referred to as 'app'). If the Kakao Navi app is installed on a user's device, the app is launched. If not, the user should be directed to the download page for the Kakao Navi app.

To check if the Kakao Navi app is installed on a user's device, use the isKakaoNaviInstalled() method. Here is an example to check if the Kakao Navi app is installed.

if (NaviClient.instance.isKakaoNaviInstalled(context)) {
    Log.i(TAG, "Possible to use navigation on Kakao Navi app.")
} else {
    Log.i(TAG, "Kakao Navi app is not installed.")
}

Start navigation

Basic information

Permission	Prerequisite	Kakao Login	User consent
-	Register platforms	-	-

To start navigation from a user's current location to the entered destination on the Kakao Navi app, call the navigateIntent() method defined in the NaviClient class. You must pass destination containing the destination information as an argument. You can also specify the desired search criteria using NaviOption. To add waypoints, pass viaList through Location object.

Parameter

Name	Type	Description	Required
destination	Location	Destination information.	O
option	NaviOption	Search criteria to get directions to the destination.	X
viaList	Location	Waypoint information. Up to three waypoints are allowed.	X

Location

Name	Type	Description	Required
name	String	Location name. (Example: "My Home", "Company")	O
rpFlag	String	Destination link. Currently not supported.	X
x	String	Longitude coordinate.	O
y	String	Latitude coordinate.	O

NaviOption

Even though you use startX, startY, and startAngle in the NaviOption class, the information of the starting point is only used for a reference, and the current information is set to a starting point when getting directions. You cannot specify a starting point for navigation.

Name	Type	Description	Required
coordType	CoordType	Coordinate system to use.	X
vehicleType	VehicleType	Vehicle type. (Default: Vehicle type the user set on the Kakao Navi app)	X
rpOption	RpOption	Criteria to optimize routes.	X
routeInfo	Boolean	Whether to view entire route information to the destination.	X
startX	Double	Longitude coordinate of the starting point. NOTE: This value is only used for a reference to get directions. For navigation, the current position is used as a starting point regardless of the designated starting point.	X
startY	Double	Latitude coordinate of the starting point. NOTE: This value is only used for a reference to get directions. For navigation, the current position is used as a starting point regardless of the designated starting point.	X
startAngle	Int	Angle of the vehicle at starting point. A value between 0 and 359. NOTE: This value is only used for a reference to get directions. For navigation, the current position is used as a starting point regardless of the designated starting point.	X
returnUri	String	URI to be redirected when stopping navigation (viewing entire routes).	X

Enum: CoordType

FOURTH	Class 4: 3-axis large truck.
FIFTH	Class 5: Special truck with four axes or more.
SIXTH	Class 6: Compact car.

Sample

Here is an example of starting navigation.

// Navigation
if (NaviClient.instance.isKakaoNaviInstalled(requireContext())) {
    // If Kakao Navi is installed, navigation starts on Kakao Navi with WGS84.
    startActivity(
        NaviClient.instance.navigateIntent(
            Location("카카오 판교오피스", "127.108640", "37.402111"),
            NaviOption(coordType = CoordType.WGS84)
        )
    )
} else {
    // If Kakao Navi is not installed, open the download page for Kakao Navi.
    startActivity(
        Intent(
            Intent.ACTION_VIEW,
            Uri.parse(Constants.WEB_NAVI_INSTALL)
        ).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP)
    )
}

This API also provides a function to specify a list of waypoints. Include each local information about the waypoints in the Location object, and pass the list of Location as viaList when calling navigateIntent.

// Navigation
if (NaviClient.instance.isKakaoNaviInstalled(requireContext())) {
    // If Kakao Navi is installed, navigation via waypoints starts on Kakao Navi with WGS84.
    startActivity(
        NaviClient.instance.navigateIntent(
            Location("카카오 판교오피스", "127.108640", "37.402111"),
            NaviOption(coordType = CoordType.WGS84),
            // Set a list of waypoints.
            listOf(
                Location("판교역 1번출구", "127.111492", "37.395225")
            )
        )
    )
} else {
    // If Kakao Navi is not installed, open the download page for Kakao Navi.
    startActivity(
        Intent(
            Intent.ACTION_VIEW,
            Uri.parse(Constants.WEB_NAVI_INSTALL)
        ).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP)
    )
}

Share location

Basic information

Permission	Prerequisite	Kakao Login	User consent
-	Register platforms	-	-

To share the specified location through the Kakao Navi app, call the shareDestinationIntent() method in the NaviClient class, which returns Intent. You must pass destination containing the location information as an argument. You can also specify the desired search criteria using NaviOption. To share loacation with waypoints, pass viaList through Location object.

Parameter

The parameters are the same as the parameters for navigateIntent().

Sample

// Sharing location
if (NaviClient.instance.isKakaoNaviInstalled(requireContext())) {
    // If Kakao Navi is installed, location is shared on Kakao Navi with WGS84.
    startActivity(
        NaviClient.instance.shareDestinationIntent(
            Location("카카오 판교오피스", "127.108640", "37.402111"),
            NaviOption(coordType = CoordType.WGS84)
        )
    )
} else {
    // If Kakao Navi is not installed, open the download page for Kakao Navi.
    startActivity(
        Intent(
            Intent.ACTION_VIEW,
            Uri.parse(Constants.WEB_NAVI_INSTALL)
        ).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP)
    )
}

This API also provides a function to specify a list of waypoints. Include each local information about the waypoints in the Location object, and pass the list of Location as viaList when calling shareDestinationIntent.

// Sharing location
if (NaviClient.instance.isKakaoNaviInstalled(requireContext())) {
    // If Kakao Navi is installed, location is shared on Kakao Navi with WGS84.
    startActivity(
        NaviClient.instance.shareDestinationIntent(
            Location("카카오 판교오피스", "127.108640", "37.402111"),
            NaviOption(coordType = CoordType.WGS84),
            // Set a list of waypoints.
            listOf(
                Location("판교역 1번출구", "127.111492", "37.395225")
            )
        )
    )
} else {
    // If Kakao Navi is not installed, open the download page for Kakao Navi.
    startActivity(
        Intent(
            Intent.ACTION_VIEW,
            Uri.parse(Constants.WEB_NAVI_INSTALL)
        ).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP)
    )
}
