Hi @lelandrichardson

I am trying to draw path on MAP from one location to another in android. For IOS MapView.Polyline working fine, But for android i am getting this error message : Error while updating property 'coordinates' of a view managed by AIRMapPolyLine.

i have following versions in my package.json file

"react": "15.4.2",
"react-native": "0.41.2",
"react-native-maps": ">=0.12.4",

Kindly Help me

@rajeshkos can you provide a stacktrace? The error message is not very helpful.

Also, for RN 0.40+ you will need react-native-maps 0.13+

@lelandrichardson Thanks for replying.

I want to implement Map in my react native app. For that I have used your plugin and Map work great for bot android and IOS.

When i am using <MapView.Polyline /> , I am able to draw path on IOS device/simulator successfully, but for android i have the above issue. Even simple map is also not opening when <MapView.Polyline /> used.

Code :

<MapView.Polyline
coordinates = {
this.state.coords
}
strokeWidth={3}
strokeColor={"red"}
fillColor="rgba(255,0,0,0.5)"
/>

Do you have any example of polyline drawing for android app ??

@rajeshkos Can you please tell how did you resolve this issue?

Hi @tanmaybhatt ,

I had defined coords like this before :

this.state = {
coords : null
}

and it was giving error.

But when i have change it to empty array it worked :

this.state = {
coords : []
}

Hope this helps you too.
👍

In my case, the problem was appearing because I was giving it an array intead of an object like this

{
  latitude: -33.4727879,
  longitude: -70.6298313
}

This can also happen if you pass extra data to the Marker. In my case I was passing an object which container latitude, longitude and some other fields.

You have to pass your coordinates like this:
{{
latitude: -33.4727879,
longitude: -70.6298313
}}

If your coordinates are in a variable named for example myLocation, you have to pass them like this (only one curly bracket):
{
myLocation
}
