java - The method done(ParseObject, ParseException) from the type new FindCallback<ParseUser>(){} is never used locally -
below error getting:

public void done(parseobject object,parseexception e) { i not sure if section of code wrongly placed in code, have added multiple log messages , realized skips entire section of code. below section:

the method done2(list<parseuser>, parseexception) type new findcallback<parseuser>(){} never used locally
your class anonymous implementation of findcallback interface, contain following signature :
public abstract void done(list<t> objects, parseexception e) your method not match signature, not used (and can't used) in program.
if code compiles correctly, mean above method has been defined. check did not mix both methods.
base on update code, here should write (but basic java. if don't understand it, suggest learning langage before trying go further. here tutorial must read , understand : http://docs.oracle.com/javase/tutorial/java/javaoo/anonymousclasses.html)
query.findinbackground(new findcallback<parseuser>() { @override public void done(list<parseuser> users,parseexception e) { // whatever need extract object "users" // ... } by way, important note won't allowed manipulate ui objects (like parseimageview r.id.profilepictureresult directly in method, because must done in ui thread. must use handler this. separate problem 1 submitted here, next one. when there, read https://developer.android.com/training/multiple-threads/communicate-ui.html
