How add some markers to map over intent API?

[dimio]

Hello! I am trying to add multiple markers to a map using Intent API.

val markers: List<Triple<Double, Double, String>> = listOf(
            Triple(51.650143, 39.163409, "Point 1"),
            Triple(51.705979, 39.208510, "Point 2"),
            Triple(51.705980, 39.208511, "Point 3"),
            Triple(51.705982, 39.208512, "Point 4"),
        )
markers.forEach { osmHelper.addMapMarker(it.first, it.second, it.third) }

But only the last marker from the list ("Point 4") is added. What am I doing wrong?

It is only 1 map marker could be displayed on top, all others should be available in the list Map Markers

The list of markers also displays only the last one.
Adding a delay when creating markers helped.

markers.forEach {
    osmHelper.addMapMarker(it.first, it.second, it.third)
    Thread.sleep(500)
}

This is a bad solution, but it worked.

it's quite strange, that AIDL communication is "broken", the reason could be if it goes multithread somehow but I wasn't aware of this.
