Why shouldInterceptRequest() does not forward WebResourceResponse when Content-Type is PDF? So basically, I have a private url that returns byte stream which I later show in WebView. Problem is my code works perfectly fine when response's content-type is application/image and do not respond when type is application/pdf. Note: Saving the streamed data as file is not the solution, as it is sensitive data. Here is the perfectly working snippet for images; @Override public WebResourceResponse shouldInterceptRequest(WebView view, String url) { try {...

How can I call a function before the doInBackground is run? So I am calling an api from the doInBackground but the link needs the name of the city which I have a function for. If I call the function from the onPreExecute() its not actually run until after the doInBackground and the applicaiton crashes since it has an improper link.

So how am I able to call the getNewLocation()...
