使用WebView在Android中显示PDF

Question

I'm trying to display PDF in Android using WebView , I'm using google docs for this purpose. It was working fine till this morning. But all of a sudden it's throwing 502 error. Is there any alternative to display PDF's in WebView .

This is the URL I have been using to render PDF in WebView

https://docs.google.com/gview?embedded=true&url= +URL

It looks like https://docs.google.com/gview?embedded=true&url= is down.

Answer 1

Try this way

@Override
    public boolean shouldOverrideUrlLoading(WebView view, String url)
    {
        if (url.endsWith(".pdf"))
        {
            // Load "url" in google docs

           String googleDocs = "https://docs.google.com/viewer?url="; 
           mWebView.loadUrl(googleDocs + url);

        }
        else
        {
            // Load all other urls normally.
            view.loadUrl(url);
        }

        return true;
     }

UPDATE try this

webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + url);
