Which one is more stable AndroidJava or AndroidKotlin ?

[milansoliya4210]

Dear Team, can you suggest me which one is more stable as of now compare to AndroidJava or AndroidKotlin ?

[ComBatVision]

Hi, AndroidKotlin is more stable as AndroidJava is obsolete and not maintained anymore. пт, 30 черв. 2023, 07:41 користувач Milan Soliya ***@***.***> пише:

If we want to implement 2D view then how it possible ?

[ComBatVision]

For now it is not possible in Kotlin and Android version. Only JS and Java. You may help to implement MercatorProjection class in feature/mercator-projection fork. This feature is half-implemented there. пт, 30 черв. 2023, 11:11 користувач Milan Soliya ***@***.***> пише:

can we integrate being map and ceisum terrain with this app using wms ?? and can we load other format apart from geopackage ?

[ComBatVision]

You can use any WMS map or terrain server пт, 30 черв. 2023, 12:39 користувач Milan Soliya ***@***.***> пише:

Hi @ComBatVision if I have to update position every two second and then the display view should be in center of location so for that what is ideal way ?? I am try to do wwd.engine.cameraFromLookAt(lookAt) once every position update but display view update after touch to screen, is there any way to sync view simultaneously ?

[ComBatVision]

You need to call wwd.requestRedraw() to apply changes on UI. вт, 4 лип. 2023, 12:35 користувач Milan Soliya ***@***.***> пише:

Thanks @ComBatVision Worked

Hi, I want to measure distance from two points (contains lat, lon) how can I measure for WGS84 using this API ? and If I want to find point p2 which is at 100 m (suppose) from point 1 and bearing between point1 and point 2 is 350 then this possible with this API ?

[ComBatVision]

Hello. This can be done by methods getDistance, getAngle and calcPoint in Location class, but there are three types of distances: great circle, rhumb or linear, which leads to 3 sets of methods. You need to pick which one do you need. пт, 21 лип. 2023, 12:23 користувач Milan Soliya ***@***.***> пише:

[milansoliya4210]

ok, thanks , if I have to consider ellipsoidal model (WGS84) for calculation then it is possible with this API?

[ComBatVision]

Location calculates distance in radians. You need to multiply it by elipsoid majorAxis. пт, 21 лип. 2023, 14:16 користувач Milan Soliya ***@***.***> пише:

Hi @ComBatVision is there any way to show placemark with heading(azimuth wrt true north) like any shape or rotating icon same as google map has circle with orientation ??

[ComBatVision]

We are usually creating another placemark with arrow icon parallel to the terrain, because arrow in 3d space can not be shown on tactical symbol plain.

[milansoliya4210]

@ComBatVision if I have to indicate azimuth (0-360) then I can rotate icon and its orientation would be not change in 3d mode ??

[ComBatVision]

Create another icon with tilt angle 90 degrees and rotate it in the plane of terrain surface

[milansoliya4210]

Thanks @ComBatVision
placeMark.imageRotationReference = OrientationMode.RELATIVE_TO_GLOBE
placeMark.imageRotation = Angle.fromDegrees(teamNode.heading.toDouble())

Simply Work for me

Hi @ComBatVision I have issue while render image tile from local storage , If I have data of zoom level 13 but for 12 not available then it will load tiles for zoom level 13 ??
This is code for loading

override fun getImageSource(x: Int, y: Int, z: Int): ImageSource { val file = File("$osmFolderPath/$z/$x/$y.png") return ImageSource.fromFile(file) }

[ComBatVision]

If you have a zoom for level 12 but tiles only from 13 then it will not show anything. пт, 3 лист. 2023, 18:37 користувач Milan Soliya ***@***.***> пише:

@ComBatVision currently what happen if I don't have data of 12 zoom level but i am try to zoom in to 13 so getImageSource(x: Int, y: Int, z: Int) try to call for zoom level 12 and it gone through exception so that it can not load zoom level 13 also

[ComBatVision]

No, if it requires level 13 it will load level 13. пт, 3 лист. 2023, 19:00 користувач Milan Soliya ***@***.***> пише:

[milansoliya4210]

ok, @ComBatVision and if for current zoom level if all tiles are not available then it will visible only available tile for same zoom level ??

[ComBatVision]

It will show only available tiles or part of top level tile from 1-11 level. сб, 4 лист. 2023, 11:44 користувач Milan Soliya ***@***.***> пише:

Could you give example file?

[milansoliya4210]

solved by handle null pointer exception

override fun getImageSource(x: Int, y: Int, z: Int): ImageSource? {
    Log.i("Map", "Z :$z X:$x Y:$y")

    val file = File("$osmFolderPath/$z/$x/$y.png")
    if (file.exists()) {
        return ImageSource.fromFile(file)
    }
    return null
}
