    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl(weblink);
    }

Answer 1

WebView打不开pdf View Pdf需要用google doc或者用AdobeReadr Pdf

      protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_wbview);
        mWebView=(WebView) findViewById(R.id.web_view);

        String weblink="https://dl.dropboxusercontent.com/u/107860028/Publishing%20an%20Application%20on%20Google%20Play.pdf"; 

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