I want to open a pdf file via an Android app. So far I have written the following code:
public class PdfopenActivity extends Activity {
String selectedFilePath;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btnOpen=(Button)findViewById(R.id.button1);
btnOpen.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Sample.pdf is my file name it is in /Root/Download/Sample.pdf
// path of the file
File file = new File( Environment.getExternalStorageDirectory().getAbsolutePath() + "/Sample.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file),"application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
}
});
}
}
The pdf is 175kb and I can open the file directly on my Galaxy Tab2 tablet, but when I run my my program to open it I get the error:
An Error Occurred while opening the document.
Can anyone tell me where I am going wrong?
.
Try this out:
Button btnOpen=(Button)findViewById(R.id.button1);
btnOpen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
File file = new File("/sdcard/sample.pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
}
}
}
});
Hope this will help you.

I try to open pdf, but when I press the button, nothing happens.
Where is my mistake?
OnClickListener oclBt2 = new OnClickListener(){
public void onClick(View v) {
File file = new File("http://testserv1.p.ht/1/ksu016.pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
}
};
I corrected my code, but it doesn't work again :( when I press the button, appears the window(Sorry, but my reputation doesn't allow to post images)
OnClickListener oclBt2 = new OnClickListener(){
public void onClick(View v) {
Uri path = Uri.parse("http://testserv1.p.ht/1/ksu016.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
mWebView.loadUrl("https://docs.google.com/gview?embedded=true&url=http://hostforandroid.elitno.net/pdf-test.pdf" );
setContentView(mWebView);
}
}
};
First, File is for local files, not http URLs. Use Uri.parse("http://testserv1.p.ht/1/ksu016.pdf"); to get a Uri pointing to an http URL.
Second, there may be no PDF viewers that are set up to directly download from an HTTP URL. For greater compatibility, you can arrange to download the PDF first (using DownloadManager or your own HTTP client code), then view the local PDF file.
I want to open a pdf from a website onto an app i'm making for the kindle and android.
I think my code is right but it can't find my file and I wasn't sure if anyone knew if I should be formatting the file different since it's technically a website....
Any input would be greatly appreciated. Here's what I have so far:
Button OpenPDF = (Button) findViewById(R.id.button1);
OpenPDF.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
File pdfFile = new File("http://thisisthewebsitewithpdf.pdf");
if(pdfFile.exists()) //EXCEPTION HERE. pdfFile doesn't exist!
{
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
startActivity(pdfIntent);
}
catch(ActivityNotFoundException e)
{
Toast.makeText(PDFActivity.this, "No Application available to view pdf", Toast.LENGTH_LONG).show();
}
}
you can download the pdf to your sdcard and then open it using this activitty:
public class OpenPdf extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.OpenPdfButton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
File file = new File("/sdcard/example.pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
Toast.makeText(OpenPdf.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
}
}
});
}
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button OpenPDF = (Button) findViewById(R.id.button);
OpenPDF.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
File pdfFile = new File("res/raw/comic.pdf");
if(pdfFile.exists())
{
//Uri path = Uri.fromFile(pdfFile);
Uri path = Uri.parse("android.resource://" + getPackageName() + "/ R.raw.comic.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
// Intent pdfIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("content://package.name/" + pdfFile));
// pdfIntent.setDataAndType(path, "/assets/arduino-comic-latest.pdf");
// pdfIntent.setType("application/pdf");
// pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
startActivity(intent);
}
catch(ActivityNotFoundException e)
{
Toast.makeText(MainActivity.this, "No Application available to view pdf", Toast.LENGTH_LONG).show();
}
}
}
});
I have done this code but this is not find the path of the file.what I have to do??can Anyone help me
Thankyou
you cant do that directly, you have to use Native Library for reading PDF... library may be iText, jPedal, Mupdf, Pdfbox... etc. Google it
