I am well aware that this question has already been asked many times, but I have not yet found a working solution. This problem will be resolved if I use the activity context, but I have to use the application context due to some other problems. For other warnings and dialogs, I handled them by overriding onJsAlert () in the webchromeclient, but I cannot find how I can intercept this in my webview and create my own selection dialog.

Any suggestions / help are welcome.

Adding a dummy sample of my webview implementation

class MyWebView extends WebView
{

 MyWebView(Context context)
 {

    super(context.getApplicationContext());
    setWebChromeClient(myWebChromeClient);
    setWebViewClient(myWebViewClient);
 }
}
