Hello, i have a little problem with my Map on Android. The thing is, when i add a graphics layer the map start to jump when i move it with the finger. It's really strange. I don't know if it's maybe because i use the "developper use only" ??bugCarteArgGIS.jpg

here is a screenshot of what i mean. A black rectangle appears at th bottom of the screen and disappears. The map seems to be flickering because of this.

Thanks for your help

Can you post your source code so we can take a look at this?

I assume you are on version 10.2.8?

I am experiencing a similar issue where on map panning, the map will flicker between the above screenshot 1 & 2.

The devices I tested on were running android 5.1, 6.0.1 and 7.0. Only OS 7.0, nougat, does NOT have this issue.

Using runtime SDK for android v100.1.0.0.

Which device make and model are you using?

Which basemap are you using?

Can you reproduce with just a mapview and a map?  (meaning simplest reproducible case)

Q: Which device make and model are you using?

Huawei: OS 5.1

Samsung S6: OS 6.0.1

Which basemap are you using?

OpenStreetMap, Arcgis tiled layer

 

Can you reproduce with just a mapview and a map?  (meaning simplest reproducible case)

Nope. Only with a navigation menu.

My findings:

I have found the root cause in my solution.

I have managed to pinpoint the cause to the use of Xamarin support libraries, version 23.1.1.0. I am building to support up to API 23 only. When using support libraries version 23.4.0.1 (latest libraries for API 23), the map is not flickering.

My app:

Using ver 23.1.1.0, when building a simplest possible solution with only mapview, there is no flicker. It is only when I integrate the map with a navigation menu/drawer that the flicker is happening.

This is more closely related to .NET than Android runtime.  It may be better to post this in the .NET Runtime thread than the Android Runtime thread.
