Question

I have an application which loads urls from a website. Now I want the application to use the cache when offline. But I just get the failure page which says that im not connected to the website. At first I set the Cachemode to Load_Normal but this doesn’t help. Next I tried a realy "silly" approach using the ConnectivityManager:

cm = (ConnectivityManager) this.getSystemService(Activity.CONNECTIVITY_SERVICE);
if(cm.getActiveNetworkInfo().isConnected()){
  mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
  mfnWebView.loadUrl(url);
}
else{
  mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
  mfnWebView.loadUrl(url);
}

but this just leads to crashing the application.

Is there a simple way to load the cache when offline and existing and just if not existing showing the failure message.

OK. The code is fine above. The permission needed to be added are:

.INTERNET

.ACCESS_NETWORK_STATE

.ACCESS_WIFI_STATE
