Open online pdf file through android intent?

Question

Currently I have a pdf url, and I would like to simply using the intent to open it, however, it does not work if I put the url in intent

Answer 1

View document using below method by default application in device. Here url is the docuement url.

val browserIntent = Intent(
                    Intent.ACTION_VIEW,
                    Uri.parse(url)
            )
            (view.context as AppActivity).startActivity(browserIntent)

Answer 2

I see that you are trying this method defining the data type:

Intent intent = new Intent();
intent.setDataAndType(Uri.parse(url), "application/pdf");
startActivity(intent);

but it will cause:

ActivityNotFoundException: No Activity found to handle Intent

Use method without the type definition and it will work perfectly:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);

Answer 3

If you use Intent you will be directed to browser all the Time So ,
Use PDFView Android Widget to View Pdf With in an Android application Assuming that you already have PDF Url or You can Pass the URL to this activity using Intent

Step 1 : Add Dependencies

implementation 'com.github.barteksc:android-pdf-viewer:3.1.0-beta.1'
implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

Sync the Gradle

Step 2 : Create a Layout [Text View is Optional]

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout     xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ViewPdf">




    <com.github.barteksc.pdfviewer.PDFView
        android:id="@+id/ViewPdf"
        android:layout_height="match_parent"
        android:layout_width="match_parent"

        />

    <TextView
        android:id="@+id/txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="invisible"
        />
</RelativeLayout>

Step 3 : Here is the Activity.java files code , Add URL to pdfUrl variable in middle of the code

package com.example.firebase;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.media.Image;
import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.webkit.WebView;
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;

public class ViewPdf extends AppCompatActivity {

    private TextView txt; // You can remove if you don't want this
    private PDFView pdf;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view_pdf);
        pdf = findViewById(R.id.ViewPdf);
        txt = findViewById(R.id.txt);

        //Intent inten = getIntent();
        String pdfUrl = "Add PDF url"
        //Toast.makeText(this, pdfUrl, Toast.LENGTH_SHORT).show();


        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();
        }
    }
}

STEP 4 : Don't Forget to change / Give the pdf url in above code to make it work

Answer 4

you can try this. it works for both .pdf and .docx

 String pdfUrl = "abc.pdf"; //
 String url = "http://docs.google.com/gview?embedded=true&url=" + pdfUrl;

 WebView webView = findViewById(R.id.webview_cv_viewer);
 webView.getSettings().setSupportZoom(true);
 webView.getSettings().setJavaScriptEnabled(true);
 webView.loadUrl(url);

Answer 5

The actual error

android.content.ActivityNotFoundException: No Activity found to 
handle Intent 
{
 act=android.intent.action.VIEW 
 dat=http://oshc.zizsoft.com/oshc_testing.pdf typ=application/pdf 
}

This says that:

1. You "broadcast" and Intent to let the system try to open a PDF file
2. The system does not find any application registered to be able to handle this type of file (PDF)

You just need a PDF viewer of some kind.

Solution

Get a PDF reader app or use @Mahendra's solution.

Download source code from here (Open Pdf from url in Android Programmatically )

MainActivity.java

package com.deepshikha.openpdf;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;

public class MainActivity extends AppCompatActivity {
    WebView webview;
    ProgressBar progressbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webview = (WebView)findViewById(R.id.webview);
        progressbar = (ProgressBar) findViewById(R.id.progressbar);
        webview.getSettings().setJavaScriptEnabled(true);
        String filename ="http://www3.nd.edu/~cpoellab/teaching/cse40816/android_tutorial.pdf";
        webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + filename);

        webview.setWebViewClient(new WebViewClient() {

            public void onPageFinished(WebView view, String url){
                // do your stuff here
                progressbar.setVisibility(View.GONE);
            }
        });

    }
