Mobile version of DogStagram (iOS and Android)

Mobile version of DogStagram (iOS and Android)


DogStagram is an app for dogs and their best friends, man (I assume!). An individual can have dogs, and a dog can have many pictures. Social interections such as likes can happen to dogs, thier pictures, comments on their pictures, and replies to comments on their pictures. Intentionally, once someone acquires a dog, they cannot leave them. So, no selling of dogs by individuals.

The commercial version of this app will have these features and more.


Basic Overview

User views other users and their dogs. User can view individual dogs too. User can acquire new dogs, like dogs, and/or their individual pictures, leave comments like commments, reply to comments, and like replies to comments.


Features of the app include the following;

  • User can create, edit, and delete an account
  • A logged in user can do the following:
    • Acqure a dog
    • View other users
    • View dogs
    • Make comments
    • Like comments
    • Reply to comments
    • Like replies to comments
    • View followers of other users
    • View users that likes a comment or reply


The goal is create a social media platform focused on dogs.


The challenges include the following;

  • Select pictures (and videos in the commercial version) from a device (iOS, Android, and Web browsers)
  • Pass picture for profile pic lifted from the device to the Rails backend
  • From the backend, store the picture file to AWS S3 via ActiveStorage
  • Not have a copy in the backend, but instead AWS S3 sends a reference to the backend upon successful upload. This is what the Rails backend’s ActiveStorage uses to generate a unique link for each record of user object photo_url, eg when a user logs in from the frontend, a successful login attempt will have a profile photo URL unique to that instace of database access and sends it to the frontend. The frontend in rendering this image URL points to the Rail backend API, which in turn processes the URL and responds with a redirect to AWS S3, and that renders to the frontend
  • Pictures for dogs are saved to a Firebase Realtime Database, not to the backend
  • The mix of storage technologies is to cut costs
  • Use Firebase Auth to enable OAuth 2.0 login authorizations from Facebook and Twitter

AfroPanTrack frontend is biult with React(^16.12.0), Axios(^0.19.1), google maps react(^2.0.2"), react google maps(^9.4.5), redux(^4.0.5), and redux thunk(^2.3.0). Ensure you have installed these packages with the specified versions or newer ones before cloning this repo. You can find their official installation guides below;

Frontend installation

To install the front end of DogStagram, do the following;

  • Clone the Frontend
  • Ensure all relevant packages from the prerequisites section above are installed by running yarn add "package-name" from your terminal
  • Follow the instructions from React Native Firebase documentation to properly set up your Firebase parameters
  • Then run cd ios && pod install && cd .. from your terminal. This installs the necesary pods
  • Then run cd android && ./gradlew clean from your terminal. This will set up required parameters for the android version of the app and you’ll likely have to fix ensuing issues
  • Then run ./gradlew signingReport && ./gradlew app:assembleRelease from your terminal. This is to ensure you have a clean slate of working build ofthe android version of the app and you’ll likely have to fix ensuing issues

####### To run the andriod version

  • To run the android version, run adb devices from your terminal to see available devices/emulators. If none is seen, you might need to properly set up android studio parameters. You’ll likely have to fix ensuing issues
  • Then run npx react-native run-android from your terminal to launch the emulator or create a biuld that can be installed on an android phone

####### To run the iOS version

  • Open the project’s workspace in Xcode and click run. You’ll likely have to fix ensuing issues

  • If the biuld passes and there is a connected phone, the app will be installed on the phone. You might need to approve permision for the app to run on your phone

  • Head over to Backend and follow the instructions to build/install the backend API

First start

After installation you need to fire up the backend API and the frontend in that order. For the backend, navigate into the folder you cloned the backend repo into(probably need to run an ls command to be sure you are in the root app folder), and run rails s. This would start the backend on the default port 3000. I used ngrok package to open up my http://localhost:3000 to the internet so that my apps can access the backend through the internet. I wrote this article detailing how to achieve that. Then in a new shell tab or new terminal window, navigate to the folder containing the cloned and properly installed frontend repo and run yarn start. You will now be given options on what platforms to run the app.

Summary of files

External datatset

  • Firebase: Google cloud-based database system

Planned improvements

Some of the planned improvements include;

  • Adding IBM Watson to add AI capabilities for registered(those that created accounts) user behaviours
  • Implement OAuth 2.0 to enable logging in using social media accounts
  • Integrate app with device programs like calenders, alarms, reminders, etc
  • Make a commercial version

Top Android Projects with Source Code

Android Projects with Source Code – Your entry pass into the world of Android

Hello Everyone, welcome to this article, which is going to be really important to all those who’re in dilemma for their projects and the project submissions. This article is also going to help you if you’re an enthusiast looking forward to explore and enhance your Android skills. The reason is that we’re here to provide you the best ideas of Android Project with source code that you can choose as per your choice.

These project ideas are simple suggestions to help you deal with the difficulty of choosing the correct projects. In this article, we’ll see the project ideas from beginners level and later we’ll move on to intermediate to advance.

top android projects with source code

Android Projects with Source Code

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project

Android Projects for beginners

1. Calculator

build a simple calculator app in android studio source code

Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.

To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.

Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.

Source Code: Simple Calculator Project

2. A Reminder App

Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.

To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.

In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.

3. Quiz Application

Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.

To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.

In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.

4. Simple Tic-Tac-Toe

android project tic tac toe game app

Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.

To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.

Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.

Source Code: Tic Tac Toe Game Project

5. Stopwatch

Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.

This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.

6. To Do App

Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.

So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.

Now for users, they will sign up and get access to the write section. Here the users can note down the things and store them permanently. Users can also alter the data or delete them. Finally, they can logout and also, login again and again whenever they like.

7. Roman to decimal converter

Android Project: This app is aimed at the conversion of Roman numbers to their significant decimal number. It’ll help to check the meaning of the roman numbers. Moreover, it will be easy to develop and will help you get your hands on coding and Android.

You need to use Android Studio, Java for coding and XML for interface. The application will take input from the users and convert them to decimal. Once it converts the Roman no. into decimal, it will show the results on the screen.

The users are supposed to just enter the Roman Number and they’ll get the decimal values on the screen. This can be a good android project for final year students.

8. Virtual Dice Roller

Android Project: Well, coming to this part that is Virtual Dice or a random no. generator. It is another simple but interesting app for computer science students. The only task that it would need to do would be to generate a number randomly. This can help people who’re often confused between two or more things.

Using a simple random number generator you can actually create something as good as this. All you’d need to do is get you hands-on OnClick listeners. And a good layout would be cherry on the cake.

The user’s task would be to set the range of the numbers and then click on the roll button. And the app will show them a randomly generated number. Isn’t it interesting ? Try soon!

9. A Scientific Calculator App

Android Project: This application is very important for you as a beginner as it will let you use your logical thinking and improve your programming skills. This is a scientific calculator that will help the users to do various calculations at ease.

To make this application you’d need to use Android Studio. Here you’d need to use arithmetic logics for the calculations. The user would need to give input to the application that will be in terms of numbers. After that, the user will give the operator as an input. Then the Application will calculate and generate the result on the user screen.

10. SMS App

Android Project: An SMS app is another easy but effective idea. It will let you send the SMS to various no. just in the same way as you use the default messaging application in your phone. This project will help you with better understanding of SMSManager in Android.

For this application, you would need to implement Java class SMSManager in Android. For the Layout you can use XML or JSON. Implementing SMSManager into the app is an easy task, so you would love this.

The user would be provided with the facility to text to whichever number they wish also, they’d be able to choose the numbers from the contact list. Another thing would be the Textbox, where they’ll enter their message. Once the message is entered they can happily click on the send button.
