Realm and auto increment Behavior (Android)

Question

I\'m trying to get data from Realm using an ID as a reference. However, when querying for an ID, I\'ve found that Realm is giving me the same ID for all elements (ID of 0).

Realm currently doesn't support auto incrementing primary keys. However you can easily implement it yourself using something like:

public int getNextKey() { 
    try { 
         Number number = realm.where(object).max("id");
         if (number != null) {
             return number.intValue() + 1;
         } else {
             return 0;
         }
    } catch (ArrayIndexOutOfBoundsException e) { 
         return 0;
    }
}

I hope that can get you started.
