Answer 1

Try this,

webview = (WebView) findViewById(R.id.webView1);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("https://docs.google.com/viewer?embedded=true&url=http://www.ctf.edu.tr/stek/pdfs/70/7001.pdf");
webview.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return false;
    }
});

Answer 2

Solution:-

You can open PDF in Google Docs Viewer by appending URL to:

http://docs.google.com/gview?embedded=true&url= This would open PDF in default browser or a WebView.

You can use this format.

https://docs.google.com/viewerng/viewer?url=http://yourfile.pdf

Just replace http://yourfile.pdf with the link you use.

Answer 3

Use this code helps, you may download or view the file by two ways like in-built browser or in the webview :-

floatingActionButton3.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://docs.google.com/gview?embedded=true&url=http://www.ctf.edu.tr/stek/pdfs/70/7001.pdf"));
startActivity(browserIntent);

        }
    });

for webview :-

WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true); 
String pdf = "http://aciltip.medicine.ankara.edu.tr/files/2015/09/2015_d45_acil_tip_hizmetleri.pdf";
webview.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf);

Answer 4

Try enabling JavaScript.

 Webview webView = (WebView) findViewById(R.id.webView1);
 webView.getSettings().setJavaScriptEnabled(true);
 webView.loadUrl(pdf_url);

Answer 5

You need to append the pdf url to Google Doc Viewer that is where you went wrong

so i created seperate variable to store pdf url and then pass it to viewer see my below code

floatingActionButton3.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                String pdf = "http://www.ctf.edu.tr/stek/pdfs/70/7001.pdf"; //your pdf address
                wv.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf); //simply append pdf address to doc viewer
            }
        });

Answer 6

Please you the following code

public class WebSample extends AppCompatActivity {

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web);

    WebView mWebview = (WebView) findViewById(R.id.web);
    WebSettings webSettings = mWebview.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript

    final Activity activity = this;

    mWebview.setWebViewClient(new WebViewClient() {
        @SuppressWarnings("deprecation")
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
        }
        @TargetApi(android.os.Build.VERSION_CODES.M)
        @Override
        public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
            // Redirect to deprecated method, so you can use it in all SDK versions
            onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
        }
    });

    String pdf = "http://aciltip.medicine.ankara.edu.tr/files/2015/09/2015_d45_acil_tip_hizmetleri.pdf";
    mWebview.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf);
