source code enable bluetooth

bluetoothadapter mbluetoothadapter = bluetoothadapter.getdefaultadapter(); if (mbluetoothadapter == null) {     // device not support bluetooth }  if (!mbluetoothadapter.isenabled()) {     intent enablebtintent = new intent(bluetoothadapter.action_request_enable);     startactivityforresult(enablebtintent, request_enable_bt); }

if enabling bluetooth succeeds, activity receive result_ok result code in onactivityresult() callback. if bluetooth not enabled due error (or user responded "no") result code result_canceled.
