my app needs user's meetup id. meetup uses oauth 2.0. found different pieces of code across web, paste in stackoverflow answer question, next person.
-- stackoverflow says "this question body not meet our quality standards..." paste piece of code below, in answer, can ignored.
in mainactivity, capture results form auth activity. mainactivity:
@override protected void onactivityresult(int requestcode, int resultcode, intent data) { // if(requestcode == 1 && resultcode == result_ok) if(requestcode == get_meetup_access_token_activity) { accesstoken = data.getextras().getstring("access_token"); savemeetupaccesstokentosharedpreferences(); //save meetupid plus device id parse getmymeetupidfrommeetupserver(); // log.i(debug_tag,"mainactivity, accesstoken" + accesstoken); } }
import library via graddle build file:
dependencies { compile 'net.smartam.leeloo:oauth2-common:0.1' compile 'net.smartam.leeloo:oauth2-client:0.1' } create class meetup authenticating. class written adrianmaurer (https://gist.github.com/adrianmaurer/4673944), thank adrianmaurer!
