Ajit Aranha commented on CB-1146:
---------------------------------
Sharing my workaround, in case it's of any help
This goes in the activity extends DroidGap class, and should probably have the
backHistory() call integrated to be a more generic fix.
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
LOG.d(TAG, "KeyDown has been triggered on the view"+keyCode);
//If volumedown key
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
// only override default behaviour is event bound
LOG.d(TAG, "Down Key Hit");
this.loadUrl("javascript:cordova.fireDocumentEvent('volumedownbutton');");
return true;
}
// If volumeup key
else if (keyCode == KeyEvent.KEYCODE_VOLUME_UP) {
LOG.d(TAG, "Up Key Hit");
this.loadUrl("javascript:cordova.fireDocumentEvent('volumeupbutton');");
return true;
}
else
{
//return super.onKeyDown(keyCode, event);
}
//return super.onKeyDown(keyCode, event);
return true;
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event)
{
LOG.d(TAG, "KeyUp has been triggered on the view"+keyCode);
// If back key
if (keyCode == KeyEvent.KEYCODE_BACK) {
this.loadUrl("javascript:cordova.fireDocumentEvent('backbutton');");
return true;
}
// Legacy
else if (keyCode == KeyEvent.KEYCODE_MENU) {
this.loadUrl("javascript:cordova.fireDocumentEvent('menubutton');");
return true;
}
// If search key
else if (keyCode == KeyEvent.KEYCODE_SEARCH) {
this.loadUrl("javascript:cordova.fireDocumentEvent('searchbutton');");
return true;
}
return false;
}

> Key: CB-1146
> URL: https://issues.apache.org/jira/browse/CB-1146
> 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
> Reporter: Ajit Aranha
> Assignee: Joe Bowser
>
> 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 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.)
> -----------EDIT FOR CLARITY------------------
> Just to state the obvious , the current page when i am doing the above is not
> the first page in history.
> If i don't show/hide the softkeyboard, the back button works perfectly and it
> goes back in history.
> -----------EDIT FOR CLARITY------------------
