Android: Why does this Email-Intent not populate the receiver field? -

i trying send email intent , prepopulate receiver field of standard email activity. however, receiver field not populated.

my code:

private void sendemail(){      if(getedittextemail().gettext().tostring().length() == 0){          final alertdialog.builder builder = new alertdialog.builder(getactivity());         builder.setmessage(r.string.bitte_email_eingeben).setcancelable(false);         builder.setnegativebutton(r.string.ok, new dialoginterface.onclicklistener() {             public void onclick(dialoginterface dialog, int id) {                 // user clicked ok button                 dialog.cancel();              }         });         builder.show();         return;     }      intent emailintent = new intent(intent.action_send);     emailintent.settype("vnd.android.cursor.dir/email");     string[] emailaddresses = new string[]{getedittextnotiz().gettext().tostring()};     emailintent.putextra(intent.extra_email, emailaddresses);     startactivity(intent.createchooser(emailintent, "sende email...")); } 

check getting text "getedittextnotiz().gettext().tostring()".

also, can change line:

intent emailintent = new intent(intent.action_send); 

to

intent emailintent = new intent("android.intent.action.send");
