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
documentsAbsolutePath Output /data/data/com.example.fyp_awais.attachfiletest2/files/documents file Output /data/data/com.example.fyp_awais.attachfiletest2/files/documents/sample.pdf 0 URI Output content://com.example.fyp_awais.attachfiletest2.fileprovider/pdf_folder/sample.pdf Menifest
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.example.fyp_awais.attachfiletest2.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/filepath" /> </provider> FilePath.xml
<?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="pdf_folder" path="documents/"/> </paths> </PreferenceScreen 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...")); Answers 2
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); Answers 4
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...")); Answers 5
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
