Android open pdf file via Intent

I think you forgot to specify the file. See your code, you only pointed it to the folder, but no the file itself. I think that is why it tells you that it is in wrong format, because it does not end with .pdf

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "SOMEFOLDER" + File.separator + "pdffile.pdf");

EDIT: Modify methods according to your comment

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
        // Clicking on items
        String fileName = FilesInFolder.get(position);
        open_File(fileName);
    }
});

public void open_File(String filename){
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/SOMEFOLDER", filename);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent1 = Intent.createChooser(intent, "Open With");
try {
    startActivity(intent1);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}

Open online pdf file through android intent?

You can view or download the pdf by either of the two ways i.e by opening it in device in-built browser or in the webview by embedding it in your app.

To open the pdf in browser,

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(pdf_url));
startActivity(browserIntent);

Instead to open in webview,

 WebView webView = (WebView) findViewById(R.id.webView1);
 webView.getSettings().setJavaScriptEnabled(true);
 webView.loadUrl(pdf_url);

Android open pdf file

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}   

Android intent filer for opening pdf files

Try this

  //Method to generate a MIME Type
  private static String getMimeType(String url) {
    String type = null;
    String extension = MimeTypeMap.getFileExtensionFromUrl(url);
    if (extension != null) {
        type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    }
    return type;
}

 //Method to generate File URI
 private static Uri getFileUri(String filePath) {
    Uri fileUri = null;
    File file = new File(filePath);
    try {
        if (Build.VERSION.SDK_INT >= 24) {
            Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
            m.invoke(null);
        }
        fileUri = Uri.fromFile(file);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return fileUri;
}

 //Intent
 Intent intent = new Intent(Intent.ACTION_VIEW);
 intent.setDataAndType(getFileUri(file_path), getMimeType(file_path));
 startActivity(intent);

Open a selected file (image, pdf, ...) programmatically from my Android Application?

Try the below code. I am using this code for opening a PDF file. You can use it for other files also.

File file = new File(Environment.getExternalStorageDirectory(),
                     "Report.pdf");
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 {
    startActivity(pdfOpenintent);
}
catch (ActivityNotFoundException e) {

}

If you want to open files, you can change the setDataAndType(path, "application/pdf"). If you want to open different files with the same intent, you can use Intent.createChooser(intent, "Open in...");. For more information, look at How to make an intent with multiple actions.

How can I open a PDF file via my Android app?

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.

Open PDF from within Android application using any installed reader

Wow I can't believe no one answered this! I have found the answers my-self. I am posting them to help others and save them the time it took me to figure it out.

Question 1. The files should be stored in the /res/raw folder (make the folder if it is not there)

Question 2. The path is simply ("/app_name/pdf_name") quick note use %20 for spaces in the apps name.
