java - OkHttp Request in Separate Class -
so have okhttp requests in mainactivity in order test worked. however, need move them separate class can use requests populate navagation drawer menu items. furthermore, in mainactivity, oauth of invalidating token , requesting , token needs used in requests. bit lost calling new class in mainactivity apirequest.run(); in run console.

here authpreferences
public class authpreferences { private static final string key_user = "user"; private static final string key_token = "token"; private sharedpreferences preferences; public authpreferences(context context) { preferences = context .getsharedpreferences("auth", context.mode_private); } public authpreferences(apirequests apirequests) { } public void setuser(string user) { editor editor = preferences.edit(); editor.putstring(key_user, user); editor.commit(); } public void settoken(string password) { editor editor = preferences.edit(); editor.putstring(key_token, password); editor.commit(); } public string getuser() { return preferences.getstring(key_user, null); } public string gettoken() { return preferences.getstring(key_token, null); } }
your authpreferences class has 2 constructors. 1 sets preferences field. other not. crash when use constructor not set preferences field, field null when try using it.
i recommend getting rid of second constructor. then, add constructor apirequests takes authpreferences parameter, , use populate authpreferences field (rather creating new, flawed instance of authpreferences). then, in activity, replace apirequests = new apirequests(); apirequests = new apirequests(authpreferences);, meet requirements of new constructor.
