Android App Problems sending an email with multiple attachments using File Provider.
I was using intent.putExtra(Intent.EXTRA_STREAM, Uri.parse( "file://"+csvFilePath)); and I have no issues sending single attachment file. Then I need to send multiple attachments. I have a problem to get it working.
In my AndroidManifest.xml I specify the provider with the following code :
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
Here is my xml/provider_paths
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="myfiles"
path="Android/data/com.example.abc/files/Documents"/>
</paths>
Send email code and files path are :
csvFilePath : /storage/emulated/0/Android/data/com.example.abc/files/Documents/Test123.csv
xyzFilePath : /storage/emulated/0/Android/data/com.example.abc/files/Documents/xyz123.txt
//attach multiple file
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setType("text/plain");
ArrayList<Uri> uris = new ArrayList<Uri>();
//uris.add(Uri.fromFile(new File(csvFilePath)));
//uris.add(Uri.fromFile(new File(xyzFilePath)));
// using file provider
File csvFile = new File(csvFilePath);
File xyzFile = new File(xyzFilePath);
uris.add(FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID + ".provider", csvFile ));
uris.add(FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID + ".provider", xyzFile ));
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
intent.setData(Uri.parse("mailto:" + abc#xyz.com));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
Exception raises during sending mailandroid.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SEND_MULTIPLE dat=mailto:xxx.xxxxxxxx#xxxxx.xxx flg=0x10000001 clip={null U:content://com.example.abc.provider/myfiles/Test123.csv ...} (has extras) }
Found a solution with the following code :
xml/provider_paths
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
File baseDir = new File(Environment.getExternalStoragePublicDirectory (Environment.DIRECTORY_DOCUMENTS), "ABC");
if (!baseDir.exists()) {
baseDir.mkdirs();
}
Log.i("Debug", "baseDir " + baseDir.toString());
File f1 = new File(baseDir, "File1.txt");
writeToFile(f1, "This is file 1 contents 888888888");
Log.i("Debug", "f1 path" + f1.getAbsolutePath());
File f2 = new File(baseDir, "File2.txt");
writeToFile(f2, "This is file 2 contents 123456");
Log.i("Debug", "f2 path" + f2.getAbsolutePath());
String f1path = f1.toString();
String f2path = f2.toString();
string EXTRA_RECIPIENT = "janedoe#abc.com";
String message = "Test message 12345678 this is a test. ";
sendMail(f1path, f2path, message, EXTRA_RECIPIENT);
private void sendMail(String f1path, String f2path, String message, String mailTo) {
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "Test multiple attachments");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{mailTo});
File f1new = new File(f1path);
File f2new = new File(f2path);
ArrayList<Uri> uris = new ArrayList<Uri>();
uris.add(FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID + ".provider", f1new ));
uris.add(FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID + ".provider", f2new ));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(Intent.EXTRA_TEXT, message);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(intent);
}
The gmail or mail sending apps may be disabled in your mobile. Kindly check the apps are enabled.
This ActivityNotFoundException occurs mainly when there is no application to handle the intent.
Then I need to send multiple attachments. I have a problem to get it
working.
Example for multiple attachments:
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_SUBJECT, "Test multiple");
intent.putExtra(Intent.EXTRA_TEXT, "multiple attachments");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{recipient_address});
ArrayList<Uri> uris = new ArrayList<Uri>();
uris.add(Uri.fromFile(new File("/path/to/first/file")));
uris.add(Uri.fromFile(new File("/path/to/second/file")));
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
Finish with a call to startActivity() passing intent.

I have a simple logging app that collects data into three arraylists, which I want saved to a CSV file and then shared to Google Drive, email, etc.
Here is how I save the data:
StringBuilder data = new StringBuilder();
data.append("Timestamp,Mass,Change in Mass\n");
for(int i = 0; i < mass_list.size(); i++){
data.append(String.valueOf(timestamp_list.get(i))+ ","+String.valueOf(mass_list.get(i))+","+String.valueOf(mass_roc_list.get(i))+"\n");
}
FileOutputStream out = openFileOutput("scale.csv", Context.MODE_APPEND );
out.write(data.toString().getBytes());
out.close();
This just combined my ArrayLists into a string and saves the data into csv file with name scale.
Here is how I am attempting to share it:
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[{"email#gmail.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Scale Data");
emailIntent.putExtra(Intent.EXTRA_TEXT, "This is the body");
emailIntent.putExtra(Intent.EXTRA_STREAM, Environment.getExternalStorageDirectory() + "/scale.csv");
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
When I try this in an email, there is no attachment, just the body. When I try with Google Drive, just the body gets saved to a text file. I am not sure what I am doing wrong, but it probably has something to do with file locations. Maybe I am unable to find the file that I saved in?
I would appreciate any assistance and am ready to provide clarification upon request.
EDIT Using feedback
I tried one of the proposed solutions. This is what my code looks like now:
StringBuilder data = new StringBuilder();
data.append("Timestamp,Mass,Change in Mass\n");
for(int i = 0; i < mass_list.size(); i++){
data.append(String.valueOf(timestamp_list.get(i))+ ","+String.valueOf(mass_list.get(i))+","+String.valueOf(mass_roc_list.get(i))+"\n");
}
try {
//saving data to a file
FileOutputStream out = openFileOutput("scale.csv", Context.MODE_APPEND);
out.write(data.toString().getBytes());
out.close();
Context context = getApplicationContext();
String filename="/scale.csv";
File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), filename);
Uri path = FileProvider.getUriForFile(context, "com.example.scaleapp.fileprovider", filelocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent.setType("vnd.android.cursor.dir/email");
String to[] = {"email.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Scale Data");
emailIntent.putExtra(Intent.EXTRA_TEXT, "This is the body");
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
// the attachment
emailIntent.putExtra(Intent.EXTRA_STREAM, path);
//this line is where an exception occurs and "Error" is displayed on my phone
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
infoView.setText("Something worked!");
}
catch(Exception e){
e.printStackTrace();
infoView.setText("Error");
}
Everything compiles and runs normally. However, when I upload to Drive, it says "unable to upload" and when I send an email, it says "unable to attach an empty file".
Create an xml file in res/xml/provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<!--
name is the file name
path is the root of external storage, it means here: Environment.getExternalStorageDirectory()
-->
<external-path name="scale" path="."/>
<!--
another example: Environment.getExternalStorageDirectory() + File.separator + "temps" + "myFile.pdf"
-->
<external-path name="myFile" path="temps"/>
</paths>
add provider in your application tag in manifest
<!--android:name="android.support.v4.content.FileProvider"-->
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="your.application.package.fileprovider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths" />
</provider>
Finally change your code to this:
public static void sendEmailWithAttachment(Context context) {
String filename="/scale.csv";
File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), filename);
//Uri path = Uri.fromFile(filelocation);
Uri path = FileProvider.getUriForFile(context, "your.application.package.fileprovider", filelocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"email#gmail.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Scale Data");
emailIntent.putExtra(Intent.EXTRA_TEXT, "This is the body");
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
// the attachment
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
}

Hi It would help me greatly If anyone could please help me out. I have been trying to find a solution to Share my Audio File with a Text using Intent. I am just trying to share it on Whatsapp alone. It would be greatly appreciated if any of you could spare time out to help me out of this problem. When I run my code only the sound is shared. No text.
This is my code:
public void buttonClick(View v) {
try {
String a = copyFiletoExternalStorage(R.raw.accio, "accio.mp3");
String shareBody = "Here is the share content body";
Intent shareMedia = new Intent(Intent.ACTION_SEND);
//set WhatsApp application.
shareMedia.setPackage("com.whatsapp");
shareMedia.setType("*/*");
//set path of media file in ExternalStorage.
shareMedia.putExtra(Intent.EXTRA_STREAM, Uri.parse(a));
shareMedia.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
shareMedia.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(shareMedia, "Compartiendo archivo."));
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Whatsapp no se encuentra instalado", Toast.LENGTH_LONG).show();
}
}
I want the user to share the sound and the text in just one intent.
first you need to add provider_paths.xml
see this video to add file provider
my file provider
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
then add this line to AndroidManifest.xml
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
then use this code to share your voice and text
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "some text ... ");
sendIntent.setType("text/plain");
if (hasReadExternalStoragePermission()) {
Uri uriImage = FileProvider.getUriForFile(getApplicationContext(), getPackageName() + ".provider", new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "voice.wav"));
sendIntent.putExtra(Intent.EXTRA_STREAM, uriImage);
sendIntent.setType("audio/*");
}
sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(sendIntent, "share"));
I hope it has been helpful
Try to use Intent.ACTION_SEND_MULTIPLE instead of Intent.ACTION_SEND
Intent shareMedia = new Intent(Intent.ACTION_SEND_MULTIPLE);
//set WhatsApp application.
shareMedia.setPackage("com.whatsapp");
shareMedia.setType("*/*");
String[] extraMimeTypes = {"audio/*", "image/*"};
shareIntent.putExtra(Intent.EXTRA_MIME_TYPES, extraMimeTypes);
shareIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
shareMedia.putExtra(Intent.EXTRA_STREAM, Uri.parse(a));
shareMedia.putExtra(Intent.EXTRA_SUBJECT, "Subject Here");
shareMedia.putExtra(Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(shareMedia, "Compartiendo archivo."));
Problem 1: I have a pdf stored in
Environment.getExternalStorageDirectory() --> /storage/emulated/0/appname/downloads/sample.pdf
I'm sending it using normal way as shown:
File iconsStoragePath = Environment.getExternalStorageDirectory();
final String selpath = iconsStoragePath.getAbsolutePath() + "/appname/downloads/";
Intent intent = new Intent(Intent.ACTION_SEND);
Uri selectedUri = Uri.parse(selpath + "/" + item.getFilename());
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(selectedUri.toString());
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension);
intent.setType(mimeType);
intent.putExtra(Intent.EXTRA_STREAM, selectedUri);
startActivity(Intent.createChooser(intent, "Share File"));
Now the result is
The problem is file is sharing without the filename.
Problem 2: When I'm trying to use the file provider the pdf is not sharing gives me an error:
Unable to share. Please try again
Environment.getFilesDir() --> /data/data/com.myapp.name/files/myapp/downloads/sample.pdf
Manifest File:
<application>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/nnf_provider_paths" />
</provider>
</application>
xml/nnf_provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<files-path
name="root"
path="myapp/downloads" />
Code:
File path = new File(getFilesDir(), "downloads");
File file = new File(documentsPath + "/" + filename);
Uri contentUri = FileProvider.getUriForFile(getApplicationContext(), AUTHORITY, file);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_STREAM, contentUri);
intent.setType("application/pdf");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
Which is the better way of doing it ?
I would personally prefer #2. Read this article on how to use ShareCompat to create ShareIntents
Regarding your problem with approach #2, I guess you're missing .setData or .setDataAndUri:
This is a sample snippet which works for me for sharing images via FileProviders:
public static void shareImage(Activity context) {
Log.d(TAG, "initializing share image");
File imgPath = new File(context.getCacheDir(), DEFAULT_TEMP_DIR_NAME);
File newFile = new File(imgPath, DEFAULT_TEMP_FILENAME);
String authority = context.getPackageName() + ".fileprovider";
Log.d(TAG, "authority: " + authority);
Uri contentUri = FileProvider.getUriForFile(context, authority, newFile);
if (contentUri != null) {
Intent shareIntent = ShareCompat.IntentBuilder.from(context)
.setType("image/png")
.setStream(contentUri)
.setSubject(context.getString(R.string.share_subject))
.setText(context.getString(R.string.share_message))
.setEmailTo(new String[]{"example#example.com"})
.getIntent();
shareIntent.setData(contentUri);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivity(Intent.createChooser(
shareIntent, context.getString(R.string.share_chooser_title)));
}
}
I am trying to attach a pdf file in gmail app. I have read this and this (applied solution) I am trying as;
public static void attachFile(Context ctx) {
String TAG = "Attach";
File documentsPath = new File(ctx.getFilesDir(), "documents");
Log.i(TAG,"documentsAbsolutePath Output");
Log.i(TAG, documentsPath.getAbsolutePath().toString());
File file = new File(documentsPath, "sample.pdf");
if ( file.exists() ) {
Toast.makeText(ctx, "Exits", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(ctx, "Not Exist", Toast.LENGTH_LONG).show();
}
Log.i(TAG,"file Output");
Log.i(TAG, file.toString());
Log.i(TAG, String.valueOf(file.length()));
Uri uri = FileProvider.getUriForFile(ctx, "com.example.fyp_awais.attachfiletest2.fileprovider", file);
Log.i(TAG,"URI Output");
Log.i(TAG,uri.toString());
Intent intent = ShareCompat.IntentBuilder.from((Activity) ctx)
.setType("application/pdf")
.setStream(uri)
.setChooserTitle("Choose bar")
.createChooserIntent()
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
ctx.startActivity(intent);
}
Outputs

A pdf file is saved in Galaxy Core Prime\Phone\documents. (file size: 53.7KB)
But it gives
Cannot attach empty file.
I am confused with folder-name in this line <files-path name="pdf_folder" path="documents/"/>. The file is in the \Phone\documents. Then why folder name?
Edit 1
Tried to replace setType(application/pdf) with setType("message/rfc822") But did not work. Any help?
Send the file in URI format like this:
Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailIntent.setData(Uri.parse("mailto:"));
emailIntent.setType("application/image");
emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
emailIntent.putExtra(Intent.EXTRA_CC, CC);
ArrayList<Uri> uris = new ArrayList<>();
//convert from paths to Android friendly Parcelable Uri's
uris.add(frontImageUri);
uris.add(backImageUri);
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
if it's ok To send Zip then try this way
String fileNameStor_zip = Environment.getExternalStorageDirectory() + "/" + fileName + ".zip";
String[] path = { your 1st pdf File Path, your 2nd pdf File Path};
Compress compress = new Compress(path, fileNameStor_zip);
compress.zip();
URI = Uri.parse("file://" + fileNameStor_zip);
Provide your Gmail Intent
intent.putExtra(Intent.EXTRA_STREAM, URI);
Uri contentUri = FileProvider.getUriForFile(this, "com.mydomain.fileprovider", newFile);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
i.setData(contentUri);
String filename="my_file.vcf";
File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), filename);
Uri path = Uri.fromFile(filelocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"asd#gmail.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
// the attachment
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
// the mail subject
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send email..."));
You have to grant the permission to access storage for gmail.
In case it helps- here's what I do in an app debug function with a few files, it shouldn't really be any different.
I do copy/export them into a user-public folder first before attaching them, and make them world readable.
if (verifyStoragePermissions(c)) {
final Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient#email.address"});
intent.putExtra(Intent.EXTRA_SUBJECT, "Email Subject");
//build up message
ArrayList<Uri> uris = new ArrayList<>();
StringBuilder content = new StringBuilder();
content.append(
String.format(
c.getString(R.string.message_log_upload_email_body) +
"\n\nmodelDesc:%s \n\nmanuf:%s \n\naId: %s,\n\nhIid: %s,\n\nfbId: %s.",
Build.MODEL, Build.MANUFACTURER, getSomeVar1(), getSomeVar2(), getSomeVar3())
);
content.append("\n\nMy logged in account id is: ").append(getAccountId(c)).append(".");
content.append("\n\nHere's an overview of my attachments:\n");
for (String s : addresses) {
File f = new File(s);
//noinspection ResultOfMethodCallIgnored
f.setReadable(true, false);
Uri add = Uri.fromFile(f);
//add attachment manifest
content.append(String.format(Locale.UK, "|-> %s (%.3f kb)\n", f.getName(), (float) f.length() / 1024));
uris.add(add);
}
//attach the things
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
//set content/message
intent.putExtra(Intent.EXTRA_TEXT, content.toString());
c.startActivity(intent);
}
}
addresses is a String[] param to that function. I build it up by making the functions I use to export the files return arrays of strings of the addresses of the files they've exported - as I initially store the files in my app's private storage
I tried with the following code but it is not attaching the pdf file.
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setType("text/plain");
if (isOnlyWhatsApp) {
sendIntent.setPackage("com.whatsapp");
}
Uri uri = Uri.fromFile(attachment);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
activity.startActivity(sendIntent);
I had this issue where I was trying to open a pdf file from assets folder and I did not work, but when I tried to open from Download folder (for example), it actually worked, and here is an example of it:
File outputFile = new File(Environment.getExternalStoragePublicDirectory
(Environment.DIRECTORY_DOWNLOADS), "example.pdf");
Uri uri = Uri.fromFile(outputFile);
Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("application/pdf");
share.putExtra(Intent.EXTRA_STREAM, uri);
share.setPackage("com.whatsapp");
activity.startActivity(share);
Please note If your targetSdkVersion is 24 or higher, we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps.
Step 1: add a FileProvider tag in AndroidManifest.xml under application tag.
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
Step 2:
then create a provider_paths.xml file in xml folder under res folder. Folder may be needed to create if it doesn't exist. The content of the file is shown below. It describes that we would like to share access to the External Storage at root folder (path=".") with the name external_files.
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
step 3: The final step is to change the line of code below in
Uri photoURI = Uri.fromFile(outputFile);
to
Uri uri = FileProvider.getUriForFile(PdfRendererActivity.this, PdfRendererActivity.this.getPackageName() + ".provider", outputFile);
step 4 (optional):
If using an intent to make the system open your file, you may need to add the following line of code:
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Hope this will help :)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
pdfUri = FileProvider.getUriForFile(this, this.getPackageName() + ".provider", pdfFile);
} else {
pdfUri = Uri.fromFile(pdfFile);
}
Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("application/pdf");
share.putExtra(Intent.EXTRA_STREAM, pdfUri);
startActivity(Intent.createChooser(share, "Share"));
If you are using Intent.createChooser then always open chooser
This works for me kotlin code.
var file =
File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),
"${invoiceNumber}.pdf"
)
if (file.exists()) {
val uri = if (Build.VERSION.SDK_INT < 24) Uri.fromFile(file) else Uri.parse(file.path)
val shareIntent = Intent().apply {
action = Intent.ACTION_SEND
type = "application/pdf"
putExtra(Intent.EXTRA_STREAM, uri)
putExtra(
Intent.EXTRA_SUBJECT,
"Purchase Bill..."
)
putExtra(
Intent.EXTRA_TEXT,
"Sharing Bill purchase items..."
)
}
startActivity(Intent.createChooser(shareIntent, "Share Via"))
}
I have used FileProvider because is a better approach.
First you need to add an xml/file_provider_paths resource with your private path configuration.
<paths>
<files-path name="files" path="/"/>
</paths>
Then you need to add the provider in your manifests
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="cu.company.app.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_provider_paths" />
</provider>
and finally in your Kotlin code
fun Context.shareFile(file: File) {
val context = this
val intent = Intent(Intent.ACTION_SEND).apply {
//file type, can be "application/pdf", "text/plain", etc
type = "*/*"
//in my case, I have used FileProvider, thats is a better approach
putExtra(
Intent.EXTRA_STREAM, FileProvider.getUriForFile(
context, "cu.company.app.provider",
file
)
)
//only whatsapp can accept this intente
//this is optional
setPackage("com.whatsapp")
}
try {
startActivity(Intent.createChooser(intent, getString(R.string.share_with)))
} catch (e: Exception) {
Toast.makeText(this, "We can't find WhatsApp", Toast.LENGTH_SHORT).show()
}
}
ACTION_VIEW is for viewing files. ACTION_VIEW will open apps which can handle pdf files in the list.
startActivity(new Intent(Intent.ACTION_VIEW).setDataAndType(Uri.fromFile(reportFile), "application/pdf")));
I thought the ACTION_SEND intent would mean "send to other app" and not striktly "send somewhere else".
Try adding Intent.setType as follows:-
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
// sendIntent.setType("text/plain");
if (isOnlyWhatsApp) {
sendIntent.setPackage("com.whatsapp");
}
Uri uri = Uri.fromFile(attachment);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
sendIntent.setType("application/pdf");
activity.startActivity(sendIntent);
For sharing text, below you can find a good example, where you can share text with specific number if you would!
public static void openWhatsAppConversation(Activity activity, String number) {
boolean isWhatsappInstalled = isAppInstalled(activity, "com.whatsapp");
if (isWhatsappInstalled) {
Uri uri = Uri.parse("smsto:" + number);
Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
sendIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
sendIntent.setPackage("com.whatsapp");
activity.startActivity(sendIntent);
} else {
ToastHelper.show(activity, "WhatsApp is not Installed!");
openMarket(activity, "com.whatsapp");
}
}
Try with following code
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
File pdfFile = new File(Environment.getExternalStoragePublicDirectory
(Environment.DIRECTORY_DOWNLOADS), "Your file");
Uri uri = Uri.fromFile(pdfFile);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("application/pdf");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share via"));
go to file manager apps in android
and open it
then go to >>>data>>>data>>>com.whatsapp and then >>>share_prefs
open com.whatsapp_preference.xml file
search and select file >>>>name=document pdf ....< /string > and save this file
after >>>setting>>>>apps>>>>whatsapp>>>>and press force stop
new open whatsapp again and try to send or share your document
