hey I want to make a call from my application, so far I found that
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(callIntent);
but there is a problem that I want to call person secretly and this call the default Activity can I write my own activity for making call or receiving call secretly (means without any UI call run on background)....??
