I am trying to share file from internal storage (as an email
attachment or with Whatsapp or similar, I don't care at this point).

I tried to mimic accepted answer from here:
https://stackoverflow.com/questions/47955490/share-text-file-via-
intent-from-internal-storage.

So I created a file res/xml/provider_paths.xml with following content:
Code: XML  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i <?xml
version="1.0" encoding="utf-8"?><paths
xmlns:android="http://schemas.android.com/apk/res/android">    <files-
path name="files" path="." /></paths>
To the AndroidManifest.xml I added:
Code: XML  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i ... <uses-
permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"
/> ... <application> ...     <provider      
 android:name="androidx.core.content.FileProvider"      
 android:authorities="${applicationId}.fileprovider"      
 android:exported="false"        android:grantUriPermissions="true"> 
     <meta-data          
 android:name="android.support.FILE_PROVIDER_PATHS"          
 android:resource="@xml/provider_paths" />    </provider> 
</application> ...   <queries>    <intent>      <action
android:name="android.intent.action.SEND"/>      <data
android:scheme="*"/>    </intent>  </queries></manifest>
And then tried this code:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.Button1Click(Sender: TObject);const cFile =
'proba.txt';var Uri: jObject;    sFullPath: String;    f:
TextFile;begin  sFullPath :=
GetEnvironmentDirectoryPath(dirInternalAppStorage)  + '/' + cFile;  
// create file if necessary  if not FileExists(sFullPath) then  begin 
  AssignFile(f, sFullPath);    Rewrite(f);    WriteLn(f,
FormatDateTime('hh:nn:ss', Now));    WriteLn(f, 'proba1.');   
CloseFile(f);  end;   Uri := GetUriFromFile(sFullPath); 
jIntentManager1.SetAction('android.intent.action.SEND'); 
jIntentManager1.PutExtraText('test'); 
jIntentManager1.PutExtraFile(Uri); 
jIntentManager1.AddFlag(ifGrantReadUriPermission); 
jIntentManager1.SetMimeType('plain/*');   if
jIntentManager1.ResolveActivity then    If
jIntentManager1.StartActivity('Send Email ...') then     
ShowMessage('Activity started')    else      ShowMessage('Activity not
started')  else    ShowMessage('Not resolved');end;
I get 'Activity not started'.

Then I changed code to:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i ...   Uri
:= GetUriFromFile(sFullPath); 
jIntentManager1.SetAction('android.intent.action.SEND'); 
jIntentManager1.SetMimeType('text/plain'); //
jIntentManager1.SetMimeType('message/rfc822');   // if I don't have
those 3 lines I get message 'Activity not started' below  jIntentManag
er1.SetDataUri(jIntentManager1.GetMailtoUri('mymail@mymail.com')); 
jIntentManager1.PutExtraMailSubject('Test 1'); 
jIntentManager1.PutExtraMailBody('This is test 1.' + LineEnding +
LineEnding + 'Regards');   jIntentManager1.PutExtraFile(Uri);  
jIntentManager1.AddFlag(ifActivityNewTask); 
jIntentManager1.AddFlag(ifGrantReadUriPermission);   if
jIntentManager1.ResolveActivity then    If
jIntentManager1.StartActivity('Send Email ...') then...
Now the activity is started (Outlook is shown with mail, subject and
body), but I get message 'Unable to add attachment'.

What can I do?
Does some have some example how to share/send attachment?
