How to send SMS with Delphi XE5 in Android

Question

Does anybody know how to get this to work? The closest I got was the code below, but got no success. At first, it gives you some hope when it tells you need the SEND_SMS permission. But after you setup this permission, nothing happens!

uses
 Androidapi.JNI.JavaTypes;

procedure TForm1.Button1Click(Sender: TObject);
var
  smsManager: JSmsManager;
  smsTo, smsFrom: JString;
begin
  smsManager:= TJSmsManager.JavaClass.getDefault;
  smsTo:= StringToJString('552199999999'); //replace with the right destination number
  smsFrom:= StringToJString('552499999999'); //replace with the right originator number
  smsManager.sendTextMessage(smsTo, smsFrom, StringToJString(Edit1.Text), nil, nil);
end;

Answer 1

Try to pass empty value (nil) to the scAddress parameter of the sendTextMessage function call to use the current default SMS center:

uses
  Androidapi.JNI.JavaTypes, Androidapi.JNI.Telephony;

procedure TForm1.Button1Click(Sender: TObject);
var
  smsTo: JString;
  smsManager: JSmsManager;
begin
  smsManager := TJSmsManager.JavaClass.getDefault;
  smsTo := StringToJString('091...');
  smsManager.sendTextMessage(smsTo, nil, StringToJString('Test SMS'), nil, nil);
end;

Answer 2

The second parameter to sendTextMessage is not the "sender" number, rather it identifies the SMS provider service center.

You almost certainly did not want to specify anything here. Simply pass nil and the SMSManager will use the device default service center for delivering your message.

sRecipient := StringToJString(edRecipient.Text);
sMessage   := StringToJString(edMessage.Text);
sendTextMessage(sRecipient, nil, sMessage, nil, nil);
