Open a PDF File Inside a Webview

How to open pdf files in webview in pdfactivity?

BINGO!! My issue resolved can open pdf directly using BufferedInputStream

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);

Second Activity is PdfViewer, bateksc pdfviewer to load pdf from url, edited as above
PdfViewer.java

package ak.wp.meto.activity;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
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();
        }
    }

}

Android does not work like iOS in this respect. The WebView widget cannot display PDF documents on Android.

You will have to:

• Use Google docs in a webview
