Simple Calculator App

This is the proverbial hello world exercise.
Learning Linux is learning to ride a bike with training wheels.

1. Features & Functionality: Basic calculations
   like addition, subtraction, multiplication, division. To begin with you can
   have a very basic user interface that contains buttons for the numbers and
   operations.
2. Outcomes: Get exposed to UI design, user input and a
   bit logic too.

To-Do List App

A to-do list will not only
familiarize you with data management and UI components but also is already
useful for keeping track of all the progressuting apps!

1. Basic Functionalities: Users can add, delete tasks
   and mark them completed.
2. Feature: Add functionality such as due dates,
   reminders and specification of task types. These give you insights into how
   data and user interactions are managed.

Weather Forecast App

A fun way to first learn about APIs

1. Weather APIs: All the above requirements combined into
   one Integrate all of them at this point with any number of APIs used to
   generate real-time data. This is a great way to learn about HTTP clients and
   JSON parsing.
2. Display the Data: Understand how to represent the
   fetched data in a readable manner. A good example is a list of forecasts that
   you could use a RecyclerView for.

Intermediate Project Ideas

Recipe Book App

Data Storage and Retrieval Notes with a Recipe Book
app

1. Data storage and retrieval: Store recipes in some
   sort of database (i.e. SQLite) Your users should be able to add, modify and
   delete their recipes.
2. UI: Clean, intuitive UI Possibly even uploaded
   pictures of food dishes made by users themselves

Expense Tracker App

It is a fantastic expense tracker app but can be
used to understand user authentication and data management.

1. Data Handling: Follow income and expenses,
   categorize transactions, generate summaries or reports.
2. User Authentiction: Implement user login and
   register. This can be controlled with firebase-authentication to keep it
   simple.

Fitness Tracker App

This app includes use of device sensors and data
visualization

1. Sensor Integration: Acess the accelerometer and
   gyroscope of the device to keep tabs on your activity.
2. Chart and Graphs: Present the information that is
   tracked in a form of graphs etc. Here libraries like MPAndroidChart can be a
   very handy.

Advanced Project Ideas

Social Media Integration App

This project will test your API handling and
security skills.

1. Multiple APIs: You can linkApis from multiple social
   media platforms. Show user posts, photos.fetch
2. Compelling Security: Keep APIs keys to be treated
   securely and never use user data as is.

E-commerce App

An e-commerce app includes functionalities from a
large range.

1. Shopping Cart: Be able to add and delete items on a
   cart Total calculations and Discounts etc.
2. Setup payment gateways: Such as PayPal / Stripe
   Maintain secure data handling and transactions.

Chat Application

A real-time chat app is extremely difficult to implement
but enjoyable.

1. Real time Communication: Web sockets or use firebase
   for real time messaging process. This is about asynchronism concept
2. Processed User Data: Implement proper user data
   privacy, security and management of user authentication (login) + efficient
   handling of their data storage.

Specialized Project Ideas

Augmented Reality (AR) App

1. Introduction to AR: Get to Know the AR Kit Competitors Making
   Some Serious Headway Untethered from Their Parent Companies via & Tango for
   T fanko Core;  Options by Jason Odom.
2. Example Projects: An app that displays info overlaid
   on physical objects, e.g. a virtual tour guide

Machine Learning App

Get your app ready for the future of AI and ML
applications.

1. Implementing Machine Learning: TensorFlow Lite
   on device machine learning model runner Basics of Tensorflow Experiments with
   Custom Video Data View all 21TensorFlowRecently I discovered the existence of…
2. Designing a Predicted Model: Develop an app where
   user can give input and it gives the predicted outcomes e.g; stock market
   predictor.

IoT Control App

Controling iot devices with android app

1. Integration with IoT Devices: Leveraging protocols
   such as MQTT for communication between other IOT devices.
2. How to actually use it: Build smart home control
   apps, environmental sensor monitoring, etc.

Gaming Projects

Simple 2D Game

Game Dev Life Is Fun and a Learning Experience

1. Basic game mechanics: Code something like a flappy
   bird clone.
2. User Interaction: Touch Sounds and basic animations

Puzzle Game

For logic and level design, the appeal of puzzle
games is obvious.

1. Level Design: Multiple levels with rise in
   difficulty level.
2. Difficulty ramps up over time: Add elements to each
   level as a means of increasing difficulty.
