15,353 PointsHi,
mContactsMethods.add(method,value);
It should be this:
mContactMethods.put(method,value);
You put an extra "s" after Contact and we use put() instead of add() when dealing with maps

1,239 Pointshi kevin in the second task i have done this again this error is coming public Set<String> getAvailableContactMethods() { // FIXME: This should return the current contact method names. Set<String> contactMethods = new HashSet<String>(); for(String s : mContactMethods.get(addContatMethod.add("phone","deepika"))){ contactMethods.add(s);
return contactMethods;
} return null; }
