[jira] [Comment Edited] (CB-1146) Application exits if back button
is pressed after a soft keyboard hide.
[ https://issues.apache.org/jira/browse/CB-1146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13423714#comment-13423714 ]

>From my deugging i believe in CordovaWebView.java in the method public boolean onKeyDown(int keyCode, KeyEvent event) the call to super.onKeyDown(keyCode, event) triggers the application exit.
workaround without modifying phonegap:
Override onKeyDown/onKeyUp in the app activity class which extends DroidGap.In my scenario i trigger javascript events, and do not delegate anything to super.onKeyXX methods. Hope the workaround does not cause any unexpected behaviour further down the road.

> Project: Apache Cordova
> Issue Type: Bug
> Components: Android
> Affects Versions: 2.0.0
> Environment: phonegap 2.0.0 on android 2.2 on an olive pad VT-100

> The back button normally cause CordovaWebView.onKeyUp to be called which typically either dispatches the event to javascript or calls backHistory().
> However if the softkeyboard is displayed and then hidden, and the android back button is then pressed onKeyUp is never called, and the application exits instead.
> (In this case i click on a html text input and either click back on the page or press android back button to hide the keyboard.Then i press the android back button to go to the previous page.)
