Right now for sdk 30, I am successfully able to send and attach a json file to some email client when using ACTION_SEND. However there are two issues that I noticed when using ACTION_SEND:
it shows ALL apps, not just email apps, which is what I want
it does NOT show the intent with title/text for the user to choose an email app. I do NOT just want to use a Toast message
I think this can be solved using ACTION_SENDTO instead, but then I won't be able to attach my file, so that actually won't work.
With this said, I would like to solve either point 1 or 2 (preferably point 1), if not both.
Here is what I have:
private void sendToEmail(String emailAddress, String filePath) {
File file = new File(filePath);
file.setReadOnly();
String[] to = { emailAddress };
Uri uri = FileProvider.getUriForFile(this, getPackageName() + ".fileprovider", file);
grantUriPermission("com.my.package", uri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
Intent intent = new Intent(Intent.ACTION_SEND);
//intent.setData(Uri.parse("mailto:")); // this does NOT work for the above action type
intent.putExtra(Intent.EXTRA_EMAIL, to);
intent.putExtra(Intent.EXTRA_SUBJECT, "Your backup file");
intent.putExtra(Intent.EXTRA_TEXT, "Your data for your backup is attached to the file " + BACKUP_NAME + ".");
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("message/rfc822");
// this does NOT create the below title for ACTION_SEND, as per documentation for createChooser()
Intent chooser = Intent.createChooser(intent, "Pick an email app to send attachment: " + BACKUP_NAME);
if (chooser.resolveActivity(getPackageManager()) != null) {
startActivity(chooser);
}
}
I am trying to send one or more CSV files in my android application. The code works fine and when the gmail app is running, the attachment and all "EXTRAS" like subject, text are available. When I send the email, the email will arrive without attachment.
The e-mail will only be sent correctly (with attachment) if I change at least one letter in the email text/body.
If I remove the EXTRA_TEXT it's the same problem, I have to enter at least one letter manuel in the GMail app.
How you can see at the code, I also tried intent.setType("plain/text")
Here is my code:
File filePath = getActivity().getApplicationContext().getFilesDir();
File files[] = filePath.listFiles();
uris = new ArrayList<>();
for (File file : files){
if(file.getPath().endsWith(".csv")){
uris.add(FileProvider.getUriForFile(getActivity(),"com.my.company", file ));
}
}
if(uris.size() > 0){
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
//intent.setType("plain/text");
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"myEmail#abc.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "new CSV");
intent.putExtra(Intent.EXTRA_TEXT, "Hello, there is a new CSV file for you");
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(Intent.createChooser(intent, "Sending multiple attachments"), REQUEST_EMAIL_CODE);
} else {
Toast.makeText(getActivity(), "no files available", Toast.LENGTH_SHORT).show();
}
Thank you for your help
I've got an intent that uses FileProvider to read from internal file storage for my app to send a file via email (or similar apps). The code works great everywhere apparently except for Gmail, which strangely adds a version of the provider path itself to the list of addressees of the email.
This is the code generating the intent:
public static Intent getSendIntent(Uri uri) {
final Intent i = new Intent(Intent.ACTION_SEND);
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.setDataAndType(uri, "message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL, new String[] { "my#email.com" });
i.putExtra(Intent.EXTRA_SUBJECT, "Export");
i.putExtra(Intent.EXTRA_TEXT, "See the attached...");
i.putExtra(Intent.EXTRA_STREAM, uri);
return i;
}
This is the code to start the activity:
File file = new File(getFilesDir(), filename);
Uri uri = FileProvider.getUriForFile(MainActivity.this, "com.example.myapplication.provider", file);
Intent i = Utils.getSendIntent(uri);
try {
startActivity(Intent.createChooser(i, "Send file..."));
} catch (Exception e) {
Log.d(TAG, "failed to start send activity: " + e.getMessage());
Toast.makeText(MainActivity.this, "No suitable activity found for export.", Toast.LENGTH_SHORT).show();
}
Works well in Slack, Evernote, etc. but in Gmail in addition to the email address I've provided, another addressee in this kind of format is added:
//com.example.myapplication.provider/my_files/filefile.csv
which prevents the email from sending until it's manually removed from the message. Everything else about the message is as expected.
Any clue how to prevent this?
The following Captain Obvious solution resolved the problem.
Replace:
i.setDataAndType(uri, "message/rfc822");
with:
i.setType("message/rfc822");
since, as #CommonsWare's question inferred, the file content isn't itself in rfc822 format.
i'm using this code to able my users to share apps via bluetooth or other networks . It works fine , the only problem I've is this ,when the app file received on the other phone ,it gets the package name as file name , it don't want to use package name as file name .
this is the code :
try {
ArrayList<Uri> uris = new ArrayList<Uri>();
Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("application/vnd.android.package-archive");
uris.add(Uri.fromFile(new File(getBaseContext().getApplicationInfo().publicSourceDir)));
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(sendIntent, null));
} catch (Exception e) {
ArrayList<Uri> uris = new ArrayList<Uri>();
Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("application/zip");
uris.add(Uri.fromFile(new File(getApplicationInfo().publicSourceDir)));
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(sendIntent, null));
}
How can I use app name as file name when It sends to others phones?
I made similier type of app long ago, You have to Copy that apk file somewhere into your sdcard and then you can rename it. Send it to anyone with any kind of name.
I thought this would be easy but as it turns out unfortunately it's not.
What I have:
I have a folder called "myFolder" on my external storage (not sd card because it's a Nexus 4, but that should not be the problem). The folder contains some *.csv files.
What I want:
I want to write a method which does the following: Show a variety of apps (file browsers) from which I can pick one (see picture). After I click on it, the selected file browser should start and show me the content of "myFolder". No more no less.
My question:
How exactly do I do that? I think I came quite close with the following code, but no matter what I do - and I'm certain that there must be something I didn't get right yet - it always opens only the main folder from the external storage.
public void openFolder()
{
File file = new File(Environment.getExternalStorageDirectory(),
"myFolder");
Log.d("path", file.toString());
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(Uri.fromFile(file), "*/*");
startActivity(intent);
}
This should help you:
Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}
Please, be sure that you have any file explorer app installed on your device.
EDIT: added a shantanu's recommendation from the comment.
LIBRARIES:
You can also have a look at the following libraries https://android-arsenal.com/tag/35 if the current solution doesn't help you.
I finally got it working. This way only a few apps are shown by the chooser (Google Drive, Dropbox, Root Explorer, and Solid Explorer). It's working fine with the two explorers but not with Google Drive and Dropbox (I guess because they cannot access the external storage). The other MIME type like "*/*" is also possible.
public void openFolder(){
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ File.separator + "myFolder" + File.separator);
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}
Here is my answer
private fun openFolder() {
val location = "/storage/emulated/0/Download/";
val intent = Intent(Intent.ACTION_VIEW)
val myDir: Uri = FileProvider.getUriForFile(context, context.applicationContext.packageName + ".provider", File(location))
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
intent.setDataAndType(myDir, DocumentsContract.Document.MIME_TYPE_DIR)
else intent.setDataAndType(myDir, "*/*")
if (intent.resolveActivityInfo(context.packageManager, 0) != null)
{
context.startActivity(intent)
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
CustomToast.toastIt(context,context.getString(R.string.there_is_no_file_explorer_app_present_text))
}
}
Here why I used FileProvider - android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData()
I tested on this device
Devices: Samsung SM-G950F (dreamltexx), Os API Level: 28
Intent chooser = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getDownloadCacheDirectory().getPath().toString());
chooser.addCategory(Intent.CATEGORY_OPENABLE);
chooser.setDataAndType(uri, "*/*");
// startActivity(chooser);
try {
startActivityForResult(chooser, SELECT_FILE);
}
catch (android.content.ActivityNotFoundException ex)
{
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
In code above, if setDataAndType is "*/*" a builtin file browser is opened to pick any file, if I set "text/plain" Dropbox is opened. I have Dropbox, Google Drive installed. If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).
Thread is old but I needed this kind of feature in my application and I found a way to do it so I decided to post it if it can help anyone in my situation.
As our device fleet is composed only by Samsung Galaxy Tab 2, I just had to find the file explorer's package name, give the right path and I succeed open my file explorer where I wanted to. I wish I could use Intent.CATEGORY_APP_FILES but it is only available in API 29.
Intent intent = context.getPackageManager().getLaunchIntentForPackage("com.sec.android.app.myfiles");
Uri uri = Uri.parse(rootPath);
if (intent != null) {
intent.setData(uri);
startActivity(intent);
}
As I said, it was easy for me because our clients have the same device but it may help others to find a workaround for their own situation.
this code will work with OI File Manager :
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);
you can get OI File manager here : http://www.openintents.org/en/filemanager
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, DocumentsContract.Document.MIME_TYPE_DIR);
startActivity(intent);
Will open files app home screen
Today, you should be representing a folder using its content: URI as obtained from the Storage Access Framework, and opening it should be as simple as:
Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("text/csv");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), 0);
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
}
then you just need to add the response
public void onActivityResult(int requestCode, int resultCode, Intent data){
switch (requestCode) {
case 0: {
//what you want to do
//file = new File(uri.getPath());
}
}
}
You seem close.
I would try to set the URI like this :
String folderPath = Environment.getExternalStorageDirectory()+"/pathTo/folder";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
Uri myUri = Uri.parse(folderPath);
intent.setDataAndType(myUri , "file/*");
startActivity(intent);
But it's not so different from what you have tried.
Tell us if it changes anything ?
Also make sure the targeted folder exists, and have a look on the resulting Uri object before to send it to the intent, it may not be what we are expected.
File temp = File.createTempFile("preview", ".png" );
String fullfileName= temp.getAbsolutePath();
final String fileName = Uri.parse(fullfileName)
.getLastPathSegment();
final String filePath = fullfileName.
substring(0,fullfileName.lastIndexOf(File.separator));
Log.d("filePath", "filePath: " + filePath);
fullfileName:
/mnt/sdcard/Download_Manager_Farsi/preview.png
filePath:
/mnt/sdcard/Download_Manager_Farsi
