[GitHub] [cordova-plugin-dialogs] goffioul opened a new issue, #160: Race condition with activityStart/activityStop can leave dialog on screen [Android]

[GitBox <gi...@apache.org>]

goffioul opened a new issue, #160:
URL: https://github.com/apache/cordova-plugin-dialogs/issues/160

   # Bug Report
   
   ## Problem
   There is a potential race condition problem in `activityStart`/`activityStop`, because the former shows the spinner dialog in the UI thread, while the latter hides the spinner dialog in the JS thread. So it is possible for `activityStop` to try to hide the spinner dialog, while it hasn't event been shown yet, if `activityStop` is executed immediately (or shortly) after `activityStart`.
   
   For instance, using the following code (e.g. in Chrome remote debugging console):
   ```
   navigator.notification.activityStart('', 'Wait...'); navigator.notification.activityStop()
   ```
   
   ### What is expected to happen?
   `activityStop` should always discard a spinner dialog initiated by `activityStart`.
   
   
   ### What does actually happen?
   `activityStop` has no effect, because the spinner dialog hasn't been created yet by `activityStart` (due to execution in UI thread).
   
   
   ### Environment, Platform, Device
