in input method service trying select text before current cursor position. following code snippet inputconnection inputconnection = getcurrentinputconnection(); extractedtext extractedtext = inputconnection.getextractedtext(new extractedtextrequest(), 0); inputconnection.setselection(extractedtext.selectionstart-1,extractedtext.selectionend); inputmethodmanager inputmethodmanager = (inputmethodmanager) getsystemservice(context.input_method_service); inputmethodmanager.updateselection(null, extractedtext.selectionstart-1,extractedtext.selectionend, 0, 0); this has flaky behaviour, selects, moves cursor 1 step back. can point out doing wrong? addition: since question has remained unanswered time, pose alternate question. looking around alternate ways of selecting text , on hackers-keyboard, pressing shift , arrow key trick, not able replicate process. tried sending d-pad keys down , key-events along meta_shift_on
