             Summary: JNI Error on HTC Evo device running android 4.0.3
                 Key: CB-2184
                 URL: https://issues.apache.org/jira/browse/CB-2184
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 2.3.0, 2.2.0
         Environment: Android 4.0.3 on HTC Evo device
            Reporter: besta
            Assignee: Joe Bowser


My app uses Cordova to implement the business logic in JS. So there is a single 
activity that loads a webview and afterwards some fragments to provide native 
UI elements.

Running the app on an Android 2.2 emulator works fine. But trying the app on my 
HTC Evo device leads to the following error:

When commenting out the JS inclusion in the loaded index.html, the native UI 
elements show up on my HTC Evo device but of course without any callback 
functionality on button clicks due to the missing JS.
