Subject [jira] [Commented] (CB-8684) support onStart/onStop lifecycle events in plugins for Android
Date Thu, 09 Apr 2015 15:37:12 GMT

    [ https://issues.apache.org/jira/browse/CB-8684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14487536#comment-14487536
] 

Tony Homer commented on CB-8684:
--------------------------------

In the original commit I pushed which used LifeCyclePluginTestActivity, I was loading a page
and the booleans were behaving as expected, otherwise my tests would not have passed.  
Maybe my page loading was not really working - I was doing it directly in LifeCyclePluginTestActivity
instead of in the Test (by dispatching an intent via setUpWithStartUrl)???
Either that or I must have broken something when I was cleaning up based on your code review
input.
Anyway, sorry you had to spend more time tweaking and thanks for the assist.

CB-8827 makes sense!

> Enable plugins to handle onStart/onStop lifecycle events in Android implementation. 
Currently plugin authors that need this feature instruct their users to modify the CordovaActivity
in their project in order to support these lifecycle events.
> For example, the Flurry plugin instructions direct users to override
> onStart and onStop in their activity in order to handle onStop:
> https://github.com/Initsogar/cordova-flurry
> There are other analytics plugins that want to know about onStart/onStop
> instead of onPause/onResume.
> This change will enable native Android support only - there will be no corresponding
Cordova lifecycle events generated because these events are platform specific.  
> In addition to the Android platform change, a "quirk"-type notation should be added to
the Android Plugin Development guide, along with possible update to the example code provided
there.
