Android can't open .xls file

In my app i've got some data which I'd like to display into an Excel sheet.
Some days ago I've already managed to build the file .xls.
I've also been able to sent it by email whith this code:
FileOutputStream fos = null;
try {
file = new File(getContext().getFilesDir(), (main.getNomeAzienda() + "" + getDate(System.currentTimeMillis(), "dd-MM-yyyy_HH-mm")) + ".xls");
fos = new FileOutputStream(file);
workbook.write(fos);
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fos != null) {
try {
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL, new String[]{FirebaseAuth.getInstance().getCurrentUser().getEmail()});
i.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(getActivity(), "com.example.authority.fileprovider", file));
i.putExtra(Intent.EXTRA_SUBJECT, "Raccolto globale aSista");
i.putExtra(Intent.EXTRA_TEXT, "In allegato il File Excel con i dati filtrati.");
try {
startActivity(Intent.createChooser(i, "Seleziona il Client di posta che vuoi utilizzare..."));
} catch (android.content.ActivityNotFoundException ex) {
Snackbar.make(main.getFab(), "Non ci sono client di posta disponibili installati sul dispositivo.", Snackbar.LENGTH_SHORT).show();
}
}
Snackbar.make(main.getFab(), "Foglio Excel generato.", Snackbar.LENGTH_SHORT).show();
Sorry if some parts of the code are in italian.
Anyway, now I'd like to display the excel file directly on the phone.
I downloaded some apps which should be able to display .xls file. Like Excel, this one from google and polaris office.
With this code i call the intent which ask the user to choose one of those app and open the file:
Uri path = Uri.fromFile(finalFile);
Intent excelIntent = new Intent(Intent.ACTION_VIEW);
excelIntent.setDataAndType(path , "application/vnd.ms-excel");
excelIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(excelIntent);
}
catch (ActivityNotFoundException e) {
Snackbar.make(main.getFab(),"Impossibile aprire il file su questo dispositivo",Snackbar.LENGTH_LONG).show();
}
I've faced some problems related to the name of the file, which should't include some special characters. Then i finally been able to start opening the file but now i've got a problem.
Excel tells me "is not possible to open the file, an error has occurred".
Google docs the same.
Polaris doesn't display errors but it show an empty file.

Your file is in getFilesDir(). That is part of internal storage, and third-party apps do not have access to your portion of internal storage.
Since you already have FileProvider set up, use the FileProvider Uri, and use Intent.FLAG_GRANT_READ_URI_PERMISSION to give temporary read access to the other app.

[Android ]Intent.ACTION_VIEW - Not found

I am having an issue, I have never had problem opening files via ACTION_VIEW the next way:
File file = new File(getActivity().getFilesDir(), TEMP_FILE_NAME);
String dataType = "image/*";
if (file.exists()) {
Intent fileIntent = new Intent(Intent.ACTION_VIEW);
fileIntent.setDataAndType(Uri.fromFile(file), dataType);
fileIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent = Intent.createChooser(fileIntent, "Open file");
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Log.e(TAG, "There is a problem when opening the file");
}
} else {
Toast.makeText(getContext(), "Invalido", Toast.LENGTH_LONG).show();
}
The problem I am having right now is that even though the file exists when I choose the app to open the file it immediately closes and tells me Not found. I have put the image I am loading in an image view and there is no problem, so the file is valid but for some reason it has conflicts when I am opening it via intent.
I am aware that it may have something to do with the way I am creating the file, I am retrieving it from Google drive so I am writing the file using the Apache Commons library the next way:
DriveContents contents = result.getDriveContents();
InputStream inputStream = contents.getInputStream();
File file = new File(getActivity().getFilesDir(), TEMP_FILE_NAME);
try {
OutputStream outputStream = new FileOutputStream(file);
IOUtils.copy(inputStream, outputStream);
IOUtils.closeQuietly(inputStream);
IOUtils.closeQuietly(outputStream);
} catch (IOException e) {
e.printStackTrace();
}
What is it I am doing wrong? I am not totally sure if the problem has to do with the copy method executing asynchronously or something like that.
Thanks in advance.

I have never had problem opening files via ACTION_VIEW the next way
That code will never work, as third-party apps have no rights to work with files on getFilesDir() of your app.
What is it I am doing wrong?
You are attempting to serve an inaccessible file to third-party programs. Use FileProvider to serve the file, using FileProvider.getUriForFile() to get the Uri to use in your ACTION_VIEW Intent.

How to open .crt file in Android ?

Few devices in android unable to read .crt (Certificate File) whereas few can. How to deal with this device related issue ? Is there any other Intent to open file other than ACTION_VIEW which can be an alternative to open file.
File vpnCerti = new File("/sdcard/VPNCertificate/Install.crt");
Uri path = Uri.fromFile(vpnCerti); //Mime Type Info : http://webdesign.about.com/od/multimedia/a/mime-types-by-content-type.htm
MimeTypeMap type_map = MimeTypeMap.getSingleton();
//Get the extension from the path
String extension = MimeTypeMap.getFileExtensionFromUrl(path.toString());
extension = extension.toLowerCase();
if (extension.contains(".")) {
extension = extension.substring(extension.lastIndexOf("."));
}
String mime_type = type_map.getMimeTypeFromExtension(extension);
Log.d("DownloadManager", "MIME Type : " + mime_type);
Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(vpnCerti), mime_type);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
Log.d("DownloadManager", "Trying to open file");
startActivity(i);
Log.d("DownloadManager", "Opened file");
}
catch(ActivityNotFoundException e)
{
Log.d("DownloadManager", "Couldn't open file");
Toast.makeText(SettingsActivity.this, "Couldn't find specific activity to open it", Toast.LENGTH_LONG).show();
}

I am not sure about the exact problem you are encountering right now (without the stack trace it is very hard to tell), but it may be because some of your devices don't have a SD card installed. In fact, I have been researching for the best solution to load a certificate, and if you only have a few certificates to manage, putting them in /res/raw/ folder might be a better idea than storing them in sd card. Here is how to load one from /res/raw/:
InputStream is = context.getResources().openRawResource(R.raw.cert_id);

How to open a pdf file in android emulator from sdcard

hi i am new to android development. i manually kept a pdf file in emulator sdcard through ddms, and i also installed "adobe reader" in emulator when i tried to read the pdf file in emulator
with the following code
File file =
new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/iTunes Connect.pdf");
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setDataAndType(path,"application/pdf");
try
{
startActivity(intent);
}
catch (ActivityNotFoundException e)
{
Toast.makeText(xv.this,
getString(R.string.app_name),
Toast.LENGTH_SHORT).show();
}
i am getting the file path is not valid error.
can any one help me in this.

use %20(for white space) in between iTunes and 20Connect.pdf.
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/iTunes%20Connect.pdf");
I think this will solve your problem

try out this path
File file=new File("/sdcard/iTunes Connect.pdf");
I think this will work for u

I think you should not use hard coded file paths.
The framework will give you the base path of the area you want to save files to.
For SD card you should, use Environment.getExternalStorageDirectory()
local files you should, use Context.getFilesDir() (or Context.openFileOutput(String name, int mode), etc)
local cache you should, use Context.getCacheDir()
For emulator you can try File file=new File("mnt/sdcard/iTunes Connect.pdf");

I think that your emulator have not adob reader install please check first it is install or not
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
} `enter code here`
