About calling in android phone

Question

I want make simple call app.

I use this code.

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:13643569345"));
startActivity(intent);

It does work well, but I don't want to use startActivity. it changes activity which system default call activity.

How can I call without using startActivity()?

Answer 1

How can I call but don't use startActivity().

You can't. There is no means to initiate a phone call except via startActivity(), except via custom firmware.
