Plugin crashes Android's WebView?

Hi,

thanks for your comment. Do you have any further information about the error ? Is it a client side (JavaScript) error or an application (Java) error? Something like a StackTrace, line of code where the error occurred would be helpful to find the cause.
Have you tried to disable the WP-Ajaxify-Comments plugin to make sure that the error is caused by the plugin?

Hope this helps…

I’ve tried disabling the plugin and the site works normally – comments go through fine on the app. Here’s the (java?) error I see when the app crashes:

The specific code in the app that seems to be breaking:

@Override
  public void onPageFinished(WebView view, String url) {
   super.onPageFinished(view, url);
   pd.dismiss();
   pd = null;
  }
 }
}

This code basically just dismisses a ‘loading’ popup in the app once a page has finished loading. I suppose there’s some bug here because the comments code isn’t technically reloading the page? I’m not sure.

Also note that there are other AJAX elements being used on the site but these don’t seem to crash?

I don’t know the internals of your Android application, but you may have to check if pd is (already) null before calling dismiss() in the onPageFinished method.

Problem seems to be fixed. Please feel free to reopen the thread if you need further assistance…

Resolved…
