  • 0

I have tweaked my Honeycomb application to work on ICS. All is well EXCEPT my ads in the webview no longer display. I have made no code changes to this section. The ICS compatible code shows ads on a HoneyComb device but not on an ICS device. What is different and how do I handle?

Here are logs that I receive on ICS device, but not HoneyComb or lower:

    The ICS WebView implementation was revamped, so a lot of us are having issues with pre-ICS and ICS WebView behavior.

    It looks like you have two problems.

    First, you want to encode your query, as it looks like you can’t pass that “%” which has a special meaning in HTML escaping. It looks like it is happening in the strIpAddress parameter. You can use code like this:

    String encodedIPAddress = URLEncoder.encode(strIpAddressValue);

    I would encode each parameter value, then put those all together into your final URL String using String.format or just String +. This way you’ll avoid any future similar problems.

    Second, Android is complaining that you’re not calling the WebView from a UI thread. I would wrap the method (I’m assuming you’re calling it showAd()) that you are calling in runInUiThread like so:

    activity.runOnUiThread(new Runnable() {
   public void run() {
      webView.showAd();
   }
});
