java - setArguments(args) is not resolvable when I creating a MainActivity newInstance method in AndroidStudio -


i creating newinstance method under android's activity class.

however, not recognize setargument method accompanies fragment. have seen before?

private static final string arg_option = "argument_option";  public static mainactivity newinstance (int option){     mainactivity fragment = new mainactivity();     bundle args = new bundle();     args.putint(arg_option, option);     fragment.setargument(args);     return  fragment;  }

you need use

fragment.setarguments(args);

instead of 

fragment.setargument(args);
