Android: Only show email apps OR display a message to user for Intent.ACTION_SEND when attaching a file

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);
}
}

Attachment is not attaching with email

I developing small android application. In that user want to take backup of SQLite database so i try to attach the SQLite database to mail, when i run this app on android device, a dialog open n displaying Gmail & some other app. When I choose Gmail it automatically displaying send mail id, subject, email content and attachment also, now I click send mail was sent to corresponding email. When I check that Email attachment is not available their ?? Why SQLite Database didn't attached ? what is wrong with my code ?
File getdbdatapath= Environment.getDataDirectory();
String currentDBPath = "/data/com.example.appname/databases/dbname/";
File path=new File(getdbdatapath, currentDBPath);
Log.d("Path", path.toString());
//File extdb= Environment.getExternalStorageDirectory();
//String extpath=extdb+"/NewFolder/dbname";
//File pathp=new File(extdb, extpath);
//Log.d("New Path", pathp.toString());
Log.i(getClass().getSimpleName(), "send task - start");
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
String address = "clientmailid#gmail.com";
String subject = "Application Database";
String emailtext = "Please check the database as attachement";
//emailIntent.setType("Application/database");
//emailIntent.setType("text/html");
//emailIntent.setType("message/rfc822");
emailIntent.setType("vnd.android.cursor.dir/email");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] { address });
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + path));
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext);
startActivity(Intent.createChooser(emailIntent, "Send Mail..."));
I referred this link1 link2 link3, changed mailIntent.setType("text/html"); to many setTypes. Get database from external also, but didn't work. Help me. Thanks in advance.
This code is working fine
String extpath=Environment.getExternalStorageDirectory() +"/NewFolder/dbname";
File pathp=new File(extpath);
in my above code it take mnt>sdcard>mnt>sdcard>NewFloder>dbname so unable to attach now this code is working fine.

you need to copy your file to a place where the email activity can access it. E.g. to sdcard.

Email database backup file from application - android

I have created the backup file for the SQLite Database i have used in my application. All i want is to send this backup file through email. I have implemented the file sending Intent but when they open, it says, you can only send files like (Image, Coarse Location etc.)
String pathname = Environment.getExternalStorageDirectory().getAbsolutePath();
String filename = "/Android/data/<package-name>/databases/hello.db";
File file=new File(pathname, filename);
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_SUBJECT, "Database Backup");
i.putExtra(Intent.EXTRA_TEXT, "Hey there, database successfully sent.");
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));`i.setType("text/plain");
startActivity(Intent.createChooser(i, "Your email id"));

The problem is due to Security reason, you can't email data from data folder, SO before emailing export it to SD card and then send, It should work.
Happy Coding !!!

Setting text/plain as attachment type probably causes email client to attempt to preview file as text. You should use other MIME type, such as "application/octet-stream", or even "any" mask - "*/*".
Here is an extremely dirty and simple snippet, that works just fine for me:
File dbFile = new File(Environment.getExternalStorageDirectory(), "example.db");
SQLiteDatabase.openOrCreateDatabase(dbFile, null);
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, "example text");
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "database sending example");
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(dbFile));
startActivity(shareIntent);

Android Attachments are not sent by email

I'm developing and android app, and at certain point i want to allow the user to send a .csv file by email.
I've seen a lot of tutorials in the web, and all of them have the same code, the same code i've tryed many times. The thing is, the send email activity starts, the attachment appears in the email, but when it is sent, the file or goes empty to the destination, or doesn't appear in the destination at all.
Here is some piece of code:
File file = null;
File dir = ProjectViewerResume.this.getCacheDir();
if (dir.canWrite()){
file = new File(dir, ProjectViewerResume.this.mProject.getName()+".csv");
FileOutputStream out = new FileOutputStream(file);
out.write(csv.toString().getBytes());
out.close();
}
Uri u1 = null;
u1 = Uri.fromFile(file);
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Project Resume: "+
ProjectViewerResume.this.mProject.getName());
sendIntent.putExtra(Intent.EXTRA_STREAM, u1);
sendIntent.setType("text/csv");
startActivity(sendIntent);
The csv variable has file content in csv format.
I've omited the try..catch so the code seems cleaner..
Thks in advance

You can try this....
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject of Email");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("/mnt/sdcard/file.csv"));
sendIntent.putExtra(Intent.EXTRA_TEXT, "Enjoy the mail");
startActivity(Intent.createChooser(sendIntent, "Email:"));
If some problem occur in attaching file try following path.
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/file.csv"));

I have the exact same problem. So not to duplicate the same post I want to show you my code, which is slightly different from yours, but still sends an email with a 0KB attachment.
I print 2 messages to the Log:
The path is printed (I edited the package name)
The size of the file is not 0KB !!!
05-11 11:32:58.133: W/Log Viewer(432): Path is /data/data/<package>/files/LogCat.log.gzip
05-11 11:32:58.192: W/Log Viewer(432): The file is 504 bytes
I stopped inside the code with the Eclipse debugger and inspected the uriLog: it is not null and contains the right path.
The code is:
public void run() {
Uri uriLog = null;
try {
FileOutputStream out = openFileOutput("LogCat.log.gzip", Context.MODE_PRIVATE);
out.write(gzip(dump().getBytes()));
out.close();
File gzipFile = new File(getFilesDir(), "LogCat.log.gzip");
//uriLog = Uri.parse("file://" + getFilesDir() + "/LogCat.log.gzip");
uriLog = Uri.fromFile(gzipFile);
Log.w(TAG,"Path is " + uriLog.getPath());
Log.w(TAG,"The file is " + gzipFile.length() + " bytes");
}
catch (IOException e) {
e.printStackTrace();
}
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Android Log");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, dump());
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, uriLog);
try {
String str = getResources().getString(R.string.send_prompt);
Intent chooser = Intent.createChooser(emailIntent, str);
startActivity(chooser);
}
catch (Exception e) {
e.printStackTrace();
}
}
}).start();
Things I tried:
I created the uri by parse (see the commented line
I also put the data inside the email body to check it exists --> it arrives in the email
I also tried to put the gziped data in the email body to check it exists --> it arrived in the email
EDIT:
Tried to send a pre-existing file in the emulator, from /mnt/system/app/CustomLocale.apk 23745 bytes
The path from uriLog.getPath() was printed /apk/CustomLocale.apk and the mail still arrived with an attachment named CustomLocale.apk and 0KB size
The only thing it occurs to me that is failing, is that putextra(intent.EXTRA_STREAM,uri) is based on
public Intent putExtra (String name, Parcelable value)
and uris implement the parcelable interface. But for some reason, which I will investigate, maybe the call to writeToParcel(Parcel out, int flags) is not writing the file data out; that's why it is 0KB in the attachment.

This code works now for me.
Using createTempFile instead of openFileOutput. I still don't know what was wrong with the former approach.
It attaches a file named LogCat.log.gzip which is not empty this time and it has the data I put insde.
public void run() {
Uri uriLog = null;
try {
File gzipFile = File.createTempFile("LogCat.log", ".gzip");
FileOutputStream out = new FileOutputStream(gzipFile);
out.write(gzip(dump().getBytes()));
out.close();
uriLog = Uri.fromFile(gzipFile);
}
catch (IOException e) {
e.printStackTrace();
}
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Android Log");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, dump());
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, uriLog);
try {
String str = getResources().getString(R.string.send_prompt);
Intent chooser = Intent.createChooser(emailIntent, str);
startActivity(chooser);
}
catch (Exception e) {
e.printStackTrace();
}
}
}).start();
And don't forget to add this line to your manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

email attachment not successful in android

consider the code below:
String outFileName = "/data/data/com.packagename/attachment.ics";
emailintent.putExtra(Intent.EXTRA_STREAM, Uri.parse(outFileName));
emailintent.setType("plain/text");
startActivity(Intent.createChooser(emailintent, "Send mail..."));
The above code is starting the email client with the attachment shown when it starts. But when i send the email, the attachment is not received. The body is being received.
what is going wrong here?
thank you in advance.
EDIT:
Is there a specific mime type that i need to put for ics files? i even tried sending a txt file, but that too is not being sent. The attachment does show up when i am trying to send the email, but it does not appear when i receive the email

i found the problem that was occurring. I was putting the file that i want to attach to the email into a private folder inside my application. The email client was not able to access..
All i had to do was put it in a public directory on the sdcard and voila.. the email client got access and i started receiving in the mails i sent from my application.
PS: Even for ics files the MIME type is plain/text.
thanks for all your help.

There are a lot of threads related to this topic.
Did you try adding this
i.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + attachmentFilePath));?
How to send an attachment with the Email in android?
Android: How do I attach a temporary, generated image to an email?
problem sending an email with an attachment programmatically

I am facing the same problem in sending email with attach SQLite database. I am Searching for the solution for this problem but i found nothing.
there is no way to send attached file via email from internal storage.
For sending file via email first save that file to external storage and then attach and send.
I am using this code for saving file to sdcard
public void copyFileToSdCard()
{
File f = new File(Environment.getExternalStorageDirectory() + "/File name");
if(f.exists())
{
}
else
{
try
{
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite())
{
String currentPath = "file path";
String backupFilePath = "file name ";
File currentFile = new File(data, currentPath);
File backupFile = new File(sd, backupFilePath);
if (currentFile.exists()) {
FileChannel src = new FileInputStream(currentFile).getChannel();
FileChannel dst = new FileOutputStream(backupFile).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
}
}
}
catch (Exception e) {
Log.w("Backup", e);
}
}
}
and this for attach and send
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] {emailAddress});
i.putExtra(Intent.EXTRA_SUBJECT, "Subject text");
i.putExtra(Intent.EXTRA_TEXT, "Body text");
Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "file name"));
i.putExtra(Intent.EXTRA_STREAM, uri);
i.setType("text/plain");
startActivity(Intent.createChooser(i, "Send mail"));

try this
emailintent.setType("text/calendar");

public class SendingMail {
public static void SendingMail(Context context) {
final Intent emailIntent = new Intent(
android.content.Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"abc#wxy.com"});
emailIntent.setType("text/html");
// Image file saved in sdcard
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+File.separator+"sdcard"
+ File.separator + "MyImage.png"));
emailIntent.putExtra(Intent.EXTRA_TEXT, "My image");
context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
}
}
This will work...
