Top 3 Appealing Android Open Source Projects For Beginners [2023]

Android Open Source Projects

When it comes to open-source projects, the first thing which comes to our minds is GitHub. GitHub is often known as the social media for developers, and it has all the right to be called with this name. There are just so many projects that you will be able to find on GitHub.

The projects are also not saturated, meaning you are sure to find projects of all sorts and writing in all languages to be present on this website. According to GitHub, the most popular language on it is JavaScript. 

If you did a simple search on GitHub, passing in your query as “android projects in GitHub,” you would be welcomed with a page that is filled to the brim with Android projects.

One cool thing about GitHub is that as long as the code is hosted on GitHub, it means that the project in question is open source. You would not have to look separately for open source projects. 

There are many reasons why you would be looking for android projects on Github. One would be if you are willing to contribute to one of these projects, the second would be if you are looking for inspiration for your own project, the third one might be that you are really interested in seeing what is going on in the open-source space. Whatever might be your reason, we have you covered. 

In the list below, we have scoured GitHub through and through in order to find android projects in GitHub, which could be used to serve many needs. One quick thing to note before we begin this list would be that we have listed the projects in no particular order.

In our attempt to make this list well suited for a plethora of purposes, we have not included a lot of entry level projects in this list. With all of that being said, it is now the time to begin with, our list.

Top Android Open Source Projects in GitHub

1. Jetpack Compose Samples

This repository is filled with many Android Studio Projects, which would help you learn more about the Compose feature of Android. You will see that each of the demonstrations that they have on their website serves different use cases. These use cases depict the ways in which you would be able to use and leverage the various APIs through various use cases, no matter how complex.

We have seen and vetted a number of apps, which you will find under this repository. We will be listing some of these apps, which should help you get a sense of what you would be expecting from this repository. The first one that we would like to mention is JetNews. This app is a straightforward app which you would be using to visit and read blog posts.

It uses the new material UI, which you would find sprinkled throughout the Android Ecosystem. The complexity to understand and build upon this is app is medium. It has the option to switch from light theme to dark theme at will, and it also offers resource loading and UI testing.

2. Camera Samples

This repo is filled to the brim from Android Studio projects, which you can use to get up to speed with the Camera API in android. There are about six projects which are hosted on the repository, which you can see to get a taste of what the Camera API has to offer. We would go over two of our picks.

The first one would be CameraXbasic. This project would demonstrate how you can write the call to the CameraX API in the language of Kotlin. If you want to build this project, you could directly run this project from the command line. There are tests in-built in this project as well.

All you would need is to run the testing module and see how that works. You can also add the testing pipeline to your android studio with ease. All you need to do is follow the elementary steps, which you can find on the repo page. There are about 13 issues that are present on this repo.

You can pick up any of these issues if you are looking to contribute to this repo. There are about six PRs also, meaning you will have to be sure that the problem that you are trying to pick has not already been solved. The next project that we are going to offer would be Camera2SlowMotion Sample.

This project is centered around the use of Camera2 API. It is used to display the preview of what a high-speed camera would see. A high-speed camera works in complete contradiction to the name High-speed because it is used to capture slow-motion videos. The high-speed camera works with the help of repeating bursts capture requests. 

You would need the Android SDK to be of 29 or above version. Your Android Studio should be above the 3.5 version. You must have a device that supports the capture of high-speed videos. If you have all the above three requirements, you can integrate this API, which they have implemented in this project, into your workflow with ease.

There are about twelve issues that are begging to be solved on this website. You can pick any one of these issues up if you are willing to have your name as one of the contributors to this repo.

What is stack?

A stack is a grouping of data that has been structured in a specific way. The first item in the stack to be accessed is the first item in the stack to be accessed, and the last item in the stack to be accessed is the previous item in the stack to be accessed. Elements is another name for the objects in the stack. Several characteristics distinguish Stacks. The first is that the most recently accessible item is also the first to be removed from the stack. This is known as the LIFO principle (last in, first out). The stack's second distinguishing property is that it is a limited data type. This means that you can only access the things on the stack in a specific sequence. The stack's third distinguishing property is that it is a linear data type. This means that you can only access one item at a time.

What are the drawbacks of using stack?

Using stack has a few disadvantages. One limitation is that a stack can only hold a limited amount of objects. If you try to load the stack with more items than it can have, the items will fall off. Another disadvantage is that keeping track of where you are in the stack might be challenging. It can be difficult to remember what was underneath an item when you remove it from the top of the stack. However, the biggest disadvantage of employing a stack is that it is a linear data structure. The items in the stack are arranged in a specified sequence and can only be accessed in that order. Similarly, the objects can only be placed in a specified sequence in the stack. Finally, the stack is a LIFO data structure (last in, first out). The elements on the stack are deleted in the reverse order in which they were added.

What are the alternatives to stack?

There are a few options for stacking. Queue, which are similar to stacks but allow items to be added and deleted from either end, is one option. Connected list, which are data arrays that are linked together, is another option. This makes it possible to quickly insert and remove elements from any point in the list.
