Joe Bowser commented on CB-1128:
--------------------------------

Right, I've added the visibility check, and moved parts of code into a runnable where appropriate, but I can't confirm this fix, since I don't have a Samsung Galaxy S running 2.3.5.

> Have implemented the Accelerometer full example (from the documentation) and after a few seconds of correct execution it crashes. The situation can be duplicated easily and happens every time. 
> The Java code is: 
> public class MainActivity extends DroidGap {
>     @Override
>     public void onCreate(Bundle savedInstanceState) {
>         super.onCreate(savedInstanceState);
>         
>         super.setStringProperty("loadingDialog", "Title,Message");
>         super.setStringProperty("errorUrl", "file:///android_asset/www/error.html");
>         super.init();
>         super.appView.clearCache(true);
>         super.setBooleanProperty("keepRunning", false);
>         super.loadUrl("file:///android_asset/www/index.html");
>     }
> }
> The HTML code is a copy-paste from the example at http://docs.phonegap.com/en/2.0.0/cordova_accelerometer_accelerometer.md.html#Accelerometer , accelerometer.watchAcceleration section, the full code sample. That's where a watch is added on the accelerometer, executing the onSuccess() every 3 seconds, which updates some div. 
> Running the application updates the div but only for a variable number of times (maybe one to three updates). The errors we're seeing bellow are at a point when a spinner dialog is about to be shown, but its view cannot be added to the view manager (or the view manager cannot instantiate a new view, don't know code details). Both, IMHO are side effects of the real reasons. If I remove the "loadingDialog" property, the application keeps on crashing, but more quietly than we may see bellow.
