 Hello,

I'm working with Poi scripts in Android. I use a .setLocation() and it works fine but when i use .callJavascript() to calll the function loadfromjson, it runs and notices me "1 place loaded" but no marker displayed.

I really need help.

This is my codes :

private fun generatePoiInformation(location: Location): JSONObject {
    // ensure these attributes are also used in JavaScript when extracting POI data
    val ATTR_ID = "id"
    val ATTR_NAME = "title"
    val ATTR_DESCRIPTION = "description"
    val ATTR_LATITUDE = "latitude"
    val ATTR_LONGITUDE = "longitude"
    val ATTR_ALTITUDE = "altitude"
    // generates 20 POIs
    val poiInformation = HashMap<String, Any>()
    poiInformation.put(ATTR_ID, "1")
    poiInformation.put(ATTR_NAME, "POI#")
    poiInformation.put(ATTR_DESCRIPTION, "This is the description of POI#")
    poiInformation.put(ATTR_LATITUDE, location.latitude)
    poiInformation.put(ATTR_LONGITUDE, location.longitude)
    val UNKNOWN_ALTITUDE = 100.0f
    // equals "AR.CONST.UNKNOWN_ALTITUDE" in JavaScript (compare AR.GeoLocation specification)
    // Use "AR.CONST.UNKNOWN_ALTITUDE" to tell ARchitect that altitude of places should be on user level. Be aware to handle altitude properly in locationManager in case you use valid POI altitude value (e.g. pass altitude only if GPS accuracy is <7m).
    poiInformation.put(ATTR_ALTITUDE, UNKNOWN_ALTITUDE)

    Log.e ("Json", JSONObject(poiInformation).toString())
    return JSONObject(poiInformation)
}

architectView.callJavascript("World.loadPoisFromJsonData(" + generatePoiInformation(mLocation) + ");")

/* Called to inject new POI data. */
loadPoisFromJsonData: function loadPoisFromJsonDataFn(poiData) {

    /*
        The example Image Recognition already explained how images are loaded and displayed in the augmented
        reality view. This sample loads an AR.ImageResource when the World variable was defined. It will be
        reused for each marker that we will create afterwards.
    */
    World.markerDrawableIdle = new AR.ImageResource("assets/marker_idle.png", {
        onError: World.onError
    });

    AR.logger.debug(poiData.latitude);

    /*
        Since there are additional changes concerning the marker it makes sense to extract the code to a
        separate Marker class (see marker.js). Parts of the code are moved from loadPoisFromJsonData to the
        Marker-class: the creation of the AR.GeoLocation, the creation of the AR.ImageDrawable and the
        creation of the AR.GeoObject. Then instantiate the Marker in the function loadPoisFromJsonData:
    */
    var marker = new Marker(poiData);

    /* Updates status message as a user feedback that everything was loaded properly. */
    World.updateStatusMessage('1 place loaded');
},

architectView.setLocation(mLocation.latitude, mLocation.longitude, mLocation.accuracy.toDouble())

I do not understand why World.loadPoisFromJsonData after architectView.callJavascript call keeps complaining my latitude is not within -90, 90. I have checked it is confirmed within -90, 90.

saveCoordinates: function saveCoordinatesFn(poiData)

    {

        var singlePoi = {

            "id": poiData.id,

            "longitude": parseFloat(poiData.longitude),

            "latitude": parseFloat(poiData.latitude),

            "altitude": parseFloat(poiData.altitude),

            "description": poiData.description,

            "title": poiData.name

        };

        World.loadPoisFromJsonData(singlePoi);

    }

I am following this example and PoiDataFromApplicationModelExtension.java

I do not understand why the data is NaN following the examples mentioned above. JSON data is healthy.

Using 9.8.0 SDK

2021-06-30 11:29:09.942 3873-3873/com.wikitude.sdksamples D/SimpleGeoArActivity: JS string info = [{"altitude":"37.0","latitude":"1.XXXXXX","name":"LOCATION#1","description":"Description for LOCATION#1","id":"1","longitude":"103.XXXXXX"}]

alert('ALT = ' + singlePoi.altitude + ' LAT = ' + singlePoi.latitude + ' LONG = ' + singlePoi.longitude);

World.loadPoisFromJsonData(singlePoi);

final JSONArray jsonArray = generatePoiInformation(loc);

architectView.callJavascript("World.saveCoordinates(" + jsonArray.toString() + ")");

Log.d(TAG, "JS string info = " + jsonArray.toString());

the document did not mention much to get it working, and there is no such example (SampleCamContentFromNativeActivity.java) to follow.

Which version of the SDK are you using?

Jai>> 9.8.0, i mentioned.

What device does this happen with (model details and OS version)?

Jai>> Android 11, Xiaomi Mi 11.

Is this happening with the sample app or in your own app? If it happens with your own app, does the sample app work on your device?

Jai>> in my own app, the sample app got no such example.

I like to know can I change the following code?

architectView.callJavascript("World.loadPoisFromJsonData(" + jsonArray.toString() + ")");

to

architectView.callJavascript("World.Jaisenddata(" + jsonArray.toString() + ")");
