> Android MainActivity cdvStartInBackground=true fails to fire pause event
> ------------------------------------------------------------------------
>
> Key: CB-13975
> URL: https://issues.apache.org/jira/browse/CB-13975
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-android
> Reporter: Rich T
> Assignee: Joe Bowser
> Priority: Major
> Attachments: CoreAndroid.java
>
>
> The MainActivity created from the template that adds support for starting the
> app in the background via the cdvStartInBackground flag doesn't fire the
> pause event. Debugging the Android code it looks like onPause is called
> before the messageChannel is set so the send event is dropped.
> There should probably be a pendingPause flag like the pendingResume.
> The reason this is a problem is that I am using the phonegap-push-plugin to
> wake the app in the background and I want to know that the app is in the
> background so I can disable polling requests which are a data and battery
> drain, currently I cannot do this and the app can just be sitting there in
> the background consuming resources it doesn't need.
