How To Open Source Code In Android

Open source codes are the codes that help in creating an application or program as freely available for use, modification and distribution. These codes are released under a software license that allows end users to study, change and improve their designs.

what is android?—-Android is an open source operating system for mobile devices and a corresponding open source project led by Google. This site and the Android Open Source Project (AOSP) repository offer the information and source code needed to create custom variants of the Android OS, port devices and accessories to the Android platform, and ensure devices meet the compatibility requirements that keep the Android ecosystem a healthy and stable environment for millions of users.

Android Open Source Project

Android is an open source operating system for mobile devices and a corresponding open source project led by Google. This site and the Android Open Source Project (AOSP) repository offer the information and source code needed to create custom variants of the Android OS, port devices and accessories to the Android platform, and ensure devices meet the compatibility requirements that keep the Android ecosystem a healthy and stable environment for millions of users.

As an open source project, Android’s goal is to avoid any central point of failure in which one industry player can restrict or control the innovations of any other player. To that end, Android is a full, production-quality operating system for consumer products, complete with customizable source code that can be ported to nearly any device and public documentation that is available to everyone (in English at source.android.com and in Simplified Chinese at source.android.google.cn).

Just as you can contribute code to AOSP, you can also contribute to AOSP documentation—and we want your input! Android’s flexibility and ever-changing codebase means this site needs your feedback to keep content fresh, accurate, and relevant to Android implementors. We encourage you to check the changelog for details on recent AOSP updates and to report bugs or offer suggestions using the Site Feedback at the bottom of every page (or by visiting g.co/androidsourceissue).

LeakCanary

Memory Leak is the most common cause of crashing an android application. As a beginner or intermediate level android developer, you have sometimes faced the fact that you have coded the application perfectly in your perspective but when you are running your app it crashes. At that time, you may feel a little bit annoyed about why this is happening. The situation could occur because of a memory leak. To understand why and when a memory leak occurs, you should read this article Memory Leaks in Android. To simplify this problem, the Square developed a library and named it LeakCanary. Basically, LeakCanary will help you with finding and fixing memory leaks in your application.

NewPipe

NewPipe - Open-Source Android Apps

NewPipe is somewhat a lightweight version of YouTube that unlocks a heap of otherwise restricted features. The app comes with a simple UI but is packed with some powerful features — background player, picture-in-picture mode, download support for offline playback and on top, it’s a completely free open-source Android app with no-ads.

OkHttp

We all know that networking is important for Androids. In the process of developing better apps, we have to connect to the internet and make a request to get data from somewhere on the internet. Data can be text, image, audio, and more. Many times we also need to send data over the internet to a specific URL. For doing these tasks, you have to write multiple lines of code and the process will be very complex when we do not use any library for this. OkHttp provides us with the comfort of doing all this stuff. It is on the list of most used libraries for networking on Android and it’s also an open-source library.

Snapdrop

Snapdrop - Open-Source Android Apps

Snapdrop is an incredible application that makes wireless file sharing between Android to any platform on the same network a much more seamless process. Just install the app on Android and on other devices use any browser of choice, and go to: https://snapdrop.net/. Tap on the device name and select files to transfer. That’s it. The Snapdrop code is a perfect choice to learn wireless file transfer in Android

Fast Android Networking

Fast Android Networking library provides the fastest way to do networking on android. It is based on OkHttp and is the most powerful open source library with which you can perform all types of networking. You can make GET, PUT, POST, and DELETE requests. You can even perform downloading and uploading files. It really makes networking fast, as its name suggests.

Network Connection Class

The library is being maintained by a big tech giant, Facebook. Facebook has many open-source software projects which are very, very useful nowadays. Assume that a user is using an app, and that app has to perform networking on a large amount of data. Like uploading a file or something. At that time, it may happen that the internet connection is not as strong for doing those tasks, so how can we inform the user that your connection is not stable or your connection is very slow? So that he can get the exact idea that the problem is with my network, not with the software or application. Otherwise, he may assume that the application is not good and it will create a negative impact on the users of the application. 

Network Connection Class provides us with the possibility of performing some task like sending a notification or a toast message whensoever the internet connection of the user is not good. It is a very good library and this feature is also going to create a better user experience for our application.

Amaze File Manager

MP Android Chart

There are many scenarios when you have to show some data to the user. Data can be of different types and the data looks much better if we represent it through charts, diagrams, or graphs. This open-source MP Android Chart provides us with more convenience to represent our data in a wonderful manner. You should use it once and check out its repository on GitHub.

Event Bus

Event Bus is another useful open source library and it enables central communication between decoupled classes with just a few lines of code. It simplifies the communication between components and decouples event senders and receivers. It can perform well with UI artifacts. It has many advanced features like subscriber priorities, delivery threads, and more. It’s also tiny and fast. The event bus is really helpful in data communication on Androids.

It’s a tiny library but it really helps when you want to remind the user to rate your app. As its name suggests, it shows a reminder at the bottom as a sheet for the user to rate your app.

Conclusion

In this article, we covered how to open source code in Android. Source code helps you understand the source of your application and make changes if needed. The best way to do this is by first installing the Open Source Code app.
