title: Is it possible to open pdf file store in sdcard/cache in webview?
body: <p>I am downloading PDF file in my application and want to allow user to view it. Is it possible that using webview I can display that pdf file downloaded to SD Card or local memory. 
  As I know there is workaround in which I can provide the link of pdf file to google url which will open pdf in webview. But it lags and is very slow.</p>
