  • Last Updated : 30 May, 2021

Social media is not a new term for us. Our daily life is incomplete, or we can say we human beings survive on food, water, air, and social media. We are dependent to such an extent that we tend to share every bit of information about ourselves on social media platforms. Similarly, Android Studio is also not a new term for an Android Developer. For beginners there always a curiosity about how a complex app like Facebook, Instagram, Twitter, Linked In, etc. is developed. How do these apps work!! How do the likes, comments functionalities work in social media apps!! How does the messaging functionality works!! And many more.

We are going to develop a clone of a social media app.

Use Case Diagram

Use Case diagram is a part of UML (Unified Modeling Language) that is used to depict the functionality of a system or a part of a system. They are widely used to illustrate the functional requirements of the system and its interaction with external agents (actors). A use case is basically a diagram representing different scenarios where the system can be used. A use case diagram gives us a high-level view of what the system or a part of the system does without going into implementation details. Below is the use case diagram for this project:



Implementation

Technology Stack Used:

A sample video is given below to get an idea about what we are going to do in this tutorial. 

This tutorial has comprised of 16 parts as the following:

Part 1: Splash Screen and Authentication Part

  • Creating a Splash Screen
  • Authentication Part:
    • Registration, and
    • Login

Part 2: Create Fragment Using Bottom Navigation

  • We are going to Create Bottom Navigation with 5 Fragments (Home, Users, AddBlog, ChatList, Profile).
  • On HomeFragment we will be Showing all the added blogs.
  • In the UsersFragment, we will be showing all the Registered Users.
  • In the AddBlogFragment We will be adding our blogs.
  • In the ChatlistFragment we will be showing a chat list of all users with whom we have chat.
  • In the ProfileFragment We will be showing the Profile of the user where we will be showing users’ data and the blogs written by the user.

Part 3: Edit Profile Data

  • We are going to edit our profile data like changing name, changing the password of the user, and changing profile pic.
  • Changing password is a very important feature because it may happen that sometimes someone knows our password and in that case, we need to change our password.
  • We change our profile pic using selecting an image from the gallery or clicking an image from the camera.

Part 4: Retrieve Profile Data



  • We are going to retrieve data of users From Firebase.
  • This is a simple fragment in which we will retrieve data of users like name, email, and profile pic from real-time Database and showing that in text layout and image layout.
  • In the future, we are also going to show the blogs of users on the profile page.

Part 5: Add Blogs

  • We are going to add blogs by any user. Here we are going to work in AddBlogs Fragment where the user will be adding a blog with a title, description, and an image related to that blogs.
  • If the user doesn’t write any of the titles or descriptions then we will be showing an error.

Part 6: Retrieve Blog On Home Page

  • We are going to retrieve the blogs written by users on HomeFragment.
  • Here we have only shown the user data and title, description, and image of the blogs, but we are also going to implement the like and comment feature in upcoming blogs.
  • Then We will be showing Post details Activity where users will be able to comment.
  • We have also implemented the Like a Blog functionality.

Part 7: Search for a Specific Blog On Home Page and Logout Functionality

  • We are going to Search For a Blog on Home Page.
  • If there are few blogs in our app then it is easy to search for a blog manually. But what happens when we have 1000 blogs then search for a particular blog became a very complicated and time taking task.
  • That’s why we are implementing this feature to search for a blog using the title or description provided.
  • Also, we have implemented the Logout functionality in this article.

Part 8: Show All Registered Users

  • We are going to Show all the Registered Users of our App.
  • We are going to show the list of users in UsersFragment.

Part 9: Search For a User Out of All Registered Users

  • We are going to Search For a user on the Users Page.
  • If there are few people registered in our app then it is easy to search for a person.
  • But what happens when we have 1000 users registered in our app then searching for a particular user became a very complicated and time taking task.
  • That’s why we are implementing this feature to search for a user using the name or email provided.

Part 10: Like a Blog Post

  • We are going to Like a Blog. We are implementing this feature using two images one like button with white background and another like button with blue background.
  • When the user clicks on the button for the first time we will change the image to the button with the background color blue and will increase the count. When the user clicks again then we will decrease the count and change the like button with background white.

Part 11: Comment on a Particular Blog

  • We are going to comment on the blog.
  • Here we are going to write a comment, and then we will be showing the comments and will be updating the comment count.
  • The comment feature is the best feature in any blogging app. It helps in interacting with the user who has written the blog and much more.

Part 12: Show All Users Who Liked On a Particular Blog

  • We are going to view the list of users who have like a particular blog.
  • After Click on total like we will be redirected to PostLikedBy.Activity.
  • In that, we will be using a recycler view to show the list of users who have liked a post.
  • We can also view the list of all users who likes our post from the PostDetailActivity.class.

Part 13: Delete a Blog Post

  • We are going to delete the Blog written by the user.
  • Blogs can only be deleted by the owner of blogs. In the top right of the blog, a button is there.
  • After clicking on that a popup will come in that Delete button will come. After clicking on Delete, the blog will be successfully deleted from the blogs.

Part 14: Create Layout & Send Message in Chat

  • We are going to Create a Layout for chat & Send Messages in Chat.
  • A user can send either a Message or an Image.
  • A user can send an image either using a camera or gallery.
  • Firstly a request for permission will be asked to send an image using a gallery or after clicking the image using the camera.
  • If permission is given then the user can send the image or it will again request for asking permission.

Part 15: Delete Messages

  • We are going to delete the message in the ChatActivity.
  • We are going to delete text and image messages. When we click on a text then an AlertBox will come.
  • There will be two options to either delete that message or cancel the event. After Click on delete message will be deleted from both sides.

Part 16: Retrieve Blogs on User Profile

  • We are going to Retrieve Blogs Written by users on their profile fragment.
  • As previously we have already added Data of users in Profile Fragment like email, name, and profile pic.
  • Here we are also going to retrieve Blogs Written By the current user on their profile.
  • Let’s See the implementation of showing the blogs written by the current user.
