Android is an open-source operating system for mobile devices like smartphones and tablets. It is a modified version of the Linux Kernel and it was first built a couple of decades ago by the Open Handset Alliance which was sponsored by Google. Later, Google took over the whole company and released several versions such as Banana Bread, Cupcake, Jellybeans, Lollipop, Marshmallow, KitKat, Oreo, etc. Today, Android is the largest operating system installed on a major chunk of mobile phones. This is also because Android does not only operate on Mobile phones but also on various devices like Tablets, Smart TVs, smartwatches, Notebooks, Set-top boxes, etc. According to a study, 72% of smartphones run on the Android Operating System. This implies that there’s a serious need for Android development and in the world advancing technically with every day that goes by, the need for good android developers today is more than ever before. Every company from local one to multinational ones is looking for skilled Android developers.
Developing android projects plays a vital role in the life of an android developer because android development projects, ranging from beginner to advanced level, are not only the best but also the easiest way to learn android. All you need to develop an Android application is the basic know-how and an understanding of the languages Java and Kotlin. Earlier Java was the official language for Android which changed to Kotlin in 2017. But you can use any of the languages to build android applications. So before you get a hands-on experience of the real world, start with some sample android projects to get the gist of what goes into creating and executing them. Following in the article are the top 15 android projects along with their source code that you must take up in order to polish your skills.
Below are the 5 android project ideas for absolute beginners along with the source code.
Tic tac toe is a two-player game wherein the players will have to choose either X or O in a 3×3 grid. The first player can choose any position in the grid and both will get one move at a time, one after the other. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game. In the backend, the game will maintain a 2-D array to save the current state of the 3×3 grid. A function will be made to check if the box that’s clicked by the player in the displaying grid is empty or not and will decide to put up an image of O if the previous one was X and vice versa. And when the consecutive images match, the game ends.
Tools/ languages required – Android Studio, Java, XML.

Preceding were the top 15 Android project ideas to get you started and continue brushing up and enhancing your skills at different levels. Working on these projects will give you a new perspective on things and you will discover things you never knew before. Also, after completely building an app, try publishing it on Google Play Store so as to get an idea of publishing the app as well. So what are you waiting for? Choose one or more of these and step into the world of Android or create one for yourself (pun intended).
Ans. Android is built almost entirely on Java and has been around for more than 20 years. Kotlin, however, is not the official language of Android. Kotlin is faster to write and compile because it has a smaller code size and it also prevents applications from increasing in size. On the other hand, Java provides a faster application experience due to its compact and light size. So the language you choose depends upon what the project demands and what interests you personally. However, for beginners, it is recommended to learn Java first.
Ans. API, short for Application Programming Interface is a set of programming instructions and standards used to communicate with a web tool or a database. API is used for exchanging information with a website, and for receiving or sending data. The end-user sends the request, the API executes the command and receives the data from the server, and responds to the user. The web API usually contains many publicly displayed conclusions that accept HTTP requests and respond to the requested data, usually in the form of JSON or XML. Other popular web APIs are Google, Facebook, Flickr, and Twitter.
Ans. Android Studio provides an integrated environment where apps for Android phones, tablets, Android Wear, Android TV, and Android Auto can be built. It fully supports you to edit C / C ++ project files so you can build JNI components into your app much quicker, and also provides a Firebase Assistant to help you connect your app to Firebase and add services like analytics, verification, alerts, and more with step-by-step processes.
Ans. APK stands for Android Application Package. It is a file format that is used to install a file in an operating system. The application on android is pre-assembled, and all its components are packed into a single file within the APK file. APK files can be saved in compressed zip format, with any uninstall or unzip tool open. The extension can also be converted to .zip or can also be opened directly using unzip tools.
Ans. An SDK key is used to activate and authenticate the Software Development Kit. Software Development Kit basically contains a specific set of software development tools that a developer needs to build an application for a particular platform. SDK Key is generated by the platforms for developers and using these SDK credentials developers can access the software development kit.
