This example shows you how to download a pdf file from server and display its contents.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it PDFFromServerExample.
2.) Write following code into your manifest file:
2.) Write following code into your manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:versionCode="1"
android:versionName="1.0" package="com.pdftest">

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
</manifest>
3.) Create Downloader.java file into your package and write following code:
package com.pdftest;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class Downloader {
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class Downloader {
public static void DownloadFile(String fileURL, File directory) {
try {
FileOutputStream f = new FileOutputStream(directory);
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection)u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
try {
FileOutputStream f = new FileOutputStream(directory);
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection)u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
f.write(buffer, 0, len1);
}
f.close();
} catch (Exception e) {
e.printStackTrace();
}
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
f.write(buffer, 0, len1);
}
f.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
4.) Run for output.
Steps:
1.) Create a project named PDFFromServerExample and set the information as stated in the image.
Build Target: Android 2.2
Application Name: PDFFromServerExample
Package Name: com.pdftest
Activity Name: PDFFromServerExample
Min SDK Version: 8
Application Name: PDFFromServerExample
Package Name: com.pdftest
Activity Name: PDFFromServerExample
Min SDK Version: 8
2.) Open PDFFromServerActivity.java file and write following code there:
package com.pdftest;
import java.io.File;
import java.io.IOException;
import java.util.List;
import java.io.IOException;
import java.util.List;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
public class PDFFromServerActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String extStorageDirectory =Environment.getExternalStorageDirectory()
.toString();
File folder = new File(extStorageDirectory, "pdf");
folder.mkdir();
File file = new File(folder, "Read.pdf");
try {
file.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
Downloader.DownloadFile("http://www.nmu.ac.in/ejournals/aspx/courselist.pdf", file);
showPdf();
}
public void showPdf()
{
File file = newFile(Environment.getExternalStorageDirectory()+"/pdf/Read.pdf");
PackageManager packageManager = getPackageManager();
Intent testIntent = new Intent(Intent.ACTION_VIEW);
testIntent.setType("application/pdf");
List list =packageManager.queryIntentActivities(testIntent, PackageManager.MATCH_DEFAULT_ONLY);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "application/pdf");
startActivity(intent);
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String extStorageDirectory =Environment.getExternalStorageDirectory()
.toString();
File folder = new File(extStorageDirectory, "pdf");
folder.mkdir();
File file = new File(folder, "Read.pdf");
try {
file.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
Downloader.DownloadFile("http://www.nmu.ac.in/ejournals/aspx/courselist.pdf", file);
showPdf();
}
public void showPdf()
{
File file = newFile(Environment.getExternalStorageDirectory()+"/pdf/Read.pdf");
PackageManager packageManager = getPackageManager();
Intent testIntent = new Intent(Intent.ACTION_VIEW);
testIntent.setType("application/pdf");
List list =packageManager.queryIntentActivities(testIntent, PackageManager.MATCH_DEFAULT_ONLY);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "application/pdf");
startActivity(intent);
}
}
3.) Compile and build the project.
