Description Brandon Minnick 2017-06-28 17:18:09 UTC
When a ConextAction is added in OnAppearing of the Cell, it does not render on Android. It does render, however, for iOS.

Reproduction Steps:
 - Download the code from GitHub, linked below.
 - Build/Deploy Android App
 - Long-press a cell in the List
 - The Context Action will not trigger

 - Build/Deploy the iOS App
 - Swipe right-to-left of a cell in the List
 - The Context Action will trigger

Comment 1 Brandon Minnick 2017-06-28 17:19:01 UTC
Workaround:

To get ContextActions working for Android, add the ContextAction in the Constructor of the Cell.
Comment 2 Jimmy [MSFT] 2017-06-29 17:57:45 UTC
I can reproduce this issue using the project provided. This appears to only affect Android as I tested with UWP to verify it works there. As mentioned in comment 1, the workaround is to add the ContextActions in the constructor.
