My application lets the user save files, but now i want to give the user the possibility to get out of my app and share the files. So i created an intend. If you do this, Android lets you select the way of exporting the file. If you choose e-mail, a new mail with attachment and attachment size will appear. But if i send the mail, i won't receive any attachments.
I'm afraid this happens because the mail app is not able to access the files in my app's folder. If this is the reason, is there an other way? I didn't find any information about this.
This is the code:
File file = new File(getFilesDir().toString()+"/"+longClickItem);
if (file.exists() == true) {
Intent sendIntent = new Intent();
sendIntent.setType("text/plain");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_EMAIL, getListView().getCheckedItemIds());
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivity(sendIntent);
} else {
...
}

private void share(Uri uri){
Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.setType("audio/*");
waIntent.putExtra("jid", get_DATA.getSelectedPhonewdcountrycode() + "#s.whatsapp.net"); //phone number without "+" prefix
waIntent.setPackage("com.whatsapp");
waIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(waIntent, "Share with"));
}
I have tried many solution but every solutio takes me to whatsapp contact list to chose a contact, i want the file to be send directly to users inbox
BTW it does take me to the targeted contact after a few second delay but it toast a message File is not supported
There is no foreseeable way to upload it directly from a file to a user (unlike on laptops), unless you extend the file path to reach a particular contact e.g
com.whatsapp.jeremy
This however might still not help as WhatsApp chats are end to end encrypted, not direct, so you might have to go through some of the database files like db.crypt to find the right path to each individual.
Try seeing how these pan out for you
I m using following code to open search intent to search text file in external storage:
private void performFileSearch()
{
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*text/*");
startActivityForResult(intent,READ_REQUEST_CODE);
}
But now I am going to create text file of custom file extension, for example textfile.tre,
this file is not search able by this intent.
So i change type to :
intent.setType("*/*");
Now intent is showing all the files. But I want to show only .tre file. What can be done?
Thanks
But I want to show only .tre file
Sorry, but that is not possible. Android, like the Web, works on MIME types, not file extensions.
I would like to open the file picker at a specific path. The user should be able to pick any file on the phone, but the SAF should show a specific folder first. I tried the following but it always opens the downloads folder. Thanks!
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
Uri uri = Uri.parse(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath());
intent.setDataAndType(uri,"image/*");
startActivityForResult(intent, 1);
you need to use the extra EXTRA_INITIAL_URI
I'm trying to load documents from files in my app using Microsoft Word and PDF viewers and I'm using a FileProvider to handle Android 7.0+ not allowing file URIs to be passed freely. I get the URI like so and and set the Intent flags to allow reading and writing before opening it, like so:
// From the byte array create a file containing that data, and get extension and MIME type.
File fileToOpen = byteArrayToFile(documentData, shortFileName);
String fileExtension = UtilityMethods.getFileExtension(fileToOpen.getName());
String mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension);
// Get the Uri for the file from the file provider, open using intent.
Uri documentUri = FileProvider.getUriForFile(getContext(), "com.mycompany.provider", fileToOpen);
Intent intent = new Intent();
intent.setDataAndType(documentUri, mime);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
intent.setAction(Intent.ACTION_VIEW);
startActivity(intent);
However when the file loads in MS Word the file is read only, and cannot be edited, which is not the desired behaviour. Where am I going wrong?
Hi I'm working on an app where I need to list all types of applications able to open a file. If the file were an image I would do something like this normally to show all applications capable of viewing the image.
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "image/*");
context.startActivity(intent);
However say I have an unknown file how could I list all applications able to view a file so the user can select the appropriate application to open the file in my application.
I also need the titles listed in an arraylist if possible so I can list them in a listview.
Thank you for any help with getting a list of applications capable of viewing a file
===================================
Edit
Alright well something easier how can i get the applications from the above intent into an arraylist i could just do image/* audio/* etc and add them all to a list and then list them in a listview and that would solve my problem
As far as i know there is no API in android that links files to a program like in windows. Your best choose I'm afraid is to build a database of known file types and program/android app linked to them.
Okay well i figured my problem out what i was looking for was
Intent audioIntent = new Intent(android.content.Intent.ACTION_VIEW);
audioIntent.setDataAndType(Uri.fromFile(Opener.file), "audio/*");
List<ResolveInfo> audio = packageManager.queryIntentActivities(audioIntent, 0);
for (ResolveInfo info : audio){
String label = info.loadLabel(packageManager).toString();
Drawable icon = info.loadIcon(packageManager);
String packageName = info.activityInfo.packageName;
String name = info.activityInfo.name;
iconlabel.add(a.new HolderObject(label, icon, audioIntent, "audio/*", packageName, name));
}
But the main thing in the code above is the queryIntentActivities method that was what solved my issue allowing me to add those apps to a list
This may help you to list the application that are capable of opening a particular file.
// extension : The file extension (.pdf, .docx)
String extension = filePath.substring(filePath.lastIndexOf(".") + 1);
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension.toLowerCase());
if (null == mimeType) {
// Need to set the mimetype for files whose mimetype is not understood by android MimeTypeMap.
mimeType = "";
}
File file = new File(filePath);
Uri data = Uri.fromFile(file);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(data, mimeType);
context.startActivity(Intent.createChooser(intent, "Complete action using"));
