Итак, я пытался реализовать представление Recycler в приложении, используя некоторые документы.В первый раз это сработало очень хорошо.Но не то, что я сделал или что случилось, мое приложение начало падать в этом представлении.

Проблема в том, что ваш класс Contacts содержит два поля (name и post), в то время как в вашей базе данных у вас есть еще два, поле uid строки и поле Access типа Object. Кроме того, ваши друзья объявляются как public вместо private. Чтобы решить эту проблему, измените класс Contacts следующим образом: 

public class Contacts {
    private String name, post, uid;
    private Access access;

    public Contacts() {}

    public Contacts(String name, String post, String uid, Access access) {
        this.name = name;
        this.post = post;
        this.uid = uid;
        this.access = access;
    }

    public String getName() { return name; }
    public String getPost() { return post; }
    public String getUid() { return uid; }
    @PropertyName("Access")
    public Access getAccess() { return access; }
}

А это ваш Access класс: 

class Access {
    private String nanded, pimpalgaon;

    public Access(){}

    public Access(String nanded, String pimpalgaon) {
        this.nanded = nanded;
        this.pimpalgaon = pimpalgaon;
    }

    @PropertyName("Nanded")
    public String getNanded() { return nanded; }

    @PropertyName("Pimpalgaon")
    public String getPimpalgaon() { return pimpalgaon; }
}

Но помните, что имена полей в вашем Access должны быть везде одинаковыми. Я выбрал их, как в первом примере, но вы должны называть эти поля так, как хотите.

В заключение, ваше приложение не будет работать, если вы не сделаете все поля в Access одинаковыми: 

Firebase-root
   |
   --- Users
        |
        --- uid
        |    |
        |    --- Access
        |    |    |
        |    |    --- nanded: "nanded" //See the name of the field
        |    |    |
        |    |    --- pimpalgaon: "pimpalgaon" //See the name of the field
        |    |
        |    --- //The other fields
        |
        --- uid
             |
             --- Access
             |    |
             |    --- nanded: "nanded" //See the name of the field
             |    |
             |    --- pimpalgaon: "pimpalgaon" //See the name of the field
             |
             --- //The other fields

Удалите эти данные и добавьте новые, используя новые классы.
