unable to open pdf in webview android app

I have faced the same problem and solved it : you have to override onStartDownload method in the web view .

There are to methods :

Force download and open it :

 webView.setDownloadListener(new DownloadListener() {
        @Override
        public void onDownloadStart(String aUrl, String userAgent, String contentDisposition, String mimetype, long contentLength) {

            fileName = URLUtil.guessFileName(aUrl, contentDisposition, mimetype); //returns a string of the name of the file THE IMPORTANT PART

                    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(aUrl));
                    request.allowScanningByMediaScanner();
                    CookieManager cookieManager = CookieManager.getInstance();
                    String cookie = cookieManager.getCookie(aUrl);
                    request.addRequestHeader("Cookie", cookie);
                    request.setMimeType("application/pdf");
                    request.addRequestHeader("User-Agent", userAgent);
                    Environment.getExternalStorageDirectory();
                    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                    request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName);
                    DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
                    dm.enqueue(request);
                    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));





        }


    });

and don't forget to add those methods to open pdf after download :

BroadcastReceiver onComplete=new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            openFile(fileName);        }
    };

    protected void openFile(String fileName) {
        File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getPath() + File.separator +
                fileName);
        Uri path = Uri.fromFile(file);
        Intent pdfOpenintent = new Intent(Intent.ACTION_VIEW);
        pdfOpenintent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        pdfOpenintent.setDataAndType(path, "application/pdf");
        try {
            this.startActivity(pdfOpenintent);
        } catch (ActivityNotFoundException e) {
        }
    }

Also don't forget declaring perrmission in the :

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

or you can only

open it in intent :

webView.setDownloadListener(new DownloadListener() {
    public void onDownloadStart(String url, String userAgent,
                String contentDisposition, String mimetype,
                long contentLength) {
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
    }
});

Both solutions are tested and works .

How to open pdf files in webview in pdfactivity?

I created two activity, First Activity to load all pdfs in webview. When user clicks the link of pdf, the pdfurl fetches the url as strings, passes strings to next activity.
PdfActivity.java

   final String pdfurl = view.getHitTestResult().getExtra();
         Intent intent = new Intent(PdfActivity.this,PdfViewer.class);
         intent.putExtra("PDFURL",pdfurl);
         startActivity(intent);

import android.view.KeyEvent;
import android.widget.TextView;
import android.widget.Toast;
import com.github.barteksc.pdfviewer.PDFView;
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import ak.wp.meto.R;

public class PdfViewer extends Activity {
    private TextView txt; // You can remove if you don't want this
    private PDFView pdf;
    String value = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom_pdf);
        Bundle bundle = getIntent().getExtras();
        if (bundle != null) {
            value = bundle.getString("PDFURL");
        }
        System.out.println("PRINT PDFVIEWER DATA" +value);
        pdf = (PDFView) findViewById(R.id.pdfView); //github.barteksc
        txt = findViewById(R.id.txtPdf);
        String pdfUrl = value;
        try{
            new RetrievePdfStream().execute(pdfUrl);
        }
        catch (Exception e){
            Toast.makeText(this, "Failed to load Url :" + e.toString(), Toast.LENGTH_SHORT).show();
        }
    }

    class RetrievePdfStream extends AsyncTask<String, Void, InputStream> {
        @Override
        protected InputStream doInBackground(String... strings) {
            InputStream inputStream = null;
            try {
                URL url = new URL(strings[0]);
                HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
                if (urlConnection.getResponseCode() == 200) {
                    inputStream = new BufferedInputStream(urlConnection.getInputStream());
                }
            } catch (IOException e) {
                return null;
            }
            return inputStream;
        }
        @Override
        protected void onPostExecute(InputStream inputStream) {
            pdf.fromStream(inputStream).load();
        }
