Robert Hoffmann created CB-2391:
-----------------------------------
Summary: useBrowserHistory true crashes app when returning from
WebView
Key: CB-2391
URL: https://issues.apache.org/jira/browse/CB-2391
Project: Apache Cordova
Issue Type: Bug
Components: Android
Affects Versions: 2.3.0
Environment: Seen on Nexus 4, Android 4.2.1
Reporter: Robert Hoffmann
Assignee: Joe Bowser
With useBrowserHistory (true) the application crashes when returning from
WebView (using the android back button).
Reproduce:
1) So from the Cordova App page
(file:///android_asset/www/app.html#BackPlace:null) the user clicks on a link
(e.g. www.google.com) which opens the WebView.
2) When clicking the back button to return to the app, the app crashes with the
exception below.
Guess:
I wonder if the hash in the originating cordova app page could be the core of
this problem (e.g. file:///android_asset/www/app.html#BackPlace:null).
Note:
The app does not crash when setting useBrowserHistory to false!
