Open source is a fundamental tenant of Android’s platform. All of Android is open sourced, which means you can download the code for all of the core Android projects from a publicly-available repository, use that code in your app and even modify or re-release your own version.
If you only learn one thing today, make it how to open the Android studio. Learning how to open Android studio isn’t as easy as learning about a PHP tutorial for beginners. The Android Studio is designed for mobile application development and deployment. Here are some simple instructions on how to open it up:

With support for documents, spreadsheets, databases, presentations, diagrams, and mathematical formulae, LibreOffice is essentially a free version of the world’s most popular office productivity suite, Microsoft 365.
Some would actually argue that LibreOffice is the more fully-featured of the two, thanks to its dedicated developer community which is adding new tools and tricks all the time. For example, in the latest update, LibreOffice added a QR code generator tool so you can quickly create mobile-friendly links.
An alternative well-known open source office tool is Open Office, which offers many similar features to LibreOffice. The reason that LibreOffice has taken the top spot today is that it is much better at preserving Microsoft file formats. In other words, your formatting won’t get screwed up if you need to modify a document originally written in Microsoft Word.
The only downside to this awesome free office software is that editing documents collaboratively online is a bit tricky. Recently, an online editing option has been added but it still requires some technical know-how to implement.
An all-in-one image editing tool that is perfect for both regular and advanced users. Whether you want to do basic editing like resize, annotate, and effects, etc. or use advanced painting tools, GIMP has everything. GIMP also supports pretty much every photo format, and you can further enhance its functionality with plugins.

Let’s start this article with one of my favorites and best-designed open-source Android apps. SoundSpice is an offline music player app that conforms to modern design language. The app’s UI is both functional and useful. It’s also a light-weight app that makes it excellent even for older Android devices. The app is 100% free to use and even brings modern UI features such as dark mode. One of my favorite features of this app is the real-time lyrics look-up. It allows me to quickly get song lyrics with a tap. If you are not using online music streaming services and still listen to your offline music collection, you should try this app.
Another beautiful and useful open-source Android application that I install instantly on a new Android device is QKSMS. It’s a third-party texting client for normal messages. My favorite feature of this app is the ability to customize the look and feel of the app. The app supports dual and multi-SIM devices so you have no problems there. It also supports normal MMS protocol allowing you to share media files like photos and audio files. One outstanding feature of this app is the ability to create group messages. Overall, I quite like this app and always prefer it over the built-in messaging app.

VLC (or VideoLAN Client) media player is a lightweight application created by an open source development group known as the VideoLAN project. This video and media player has been leading the industry for years in terms of popularity, and it’s not hard to see why. You can use VLC media player to open audio and video files in just about any format without having to hunt down extra codecs.
VLC also works for streaming media such as podcasts and online radio stations. But perhaps the greatest VLC media player feature is playback control. You can change almost everything about how your media is displayed from hardware optimization to adding subtitle files from third-party sources.
Like some of the other amazing open source offerings mentioned here, VLC is constantly being upgraded with new goodies and features to explore. The latest updates to the free video player have included the ability to stream to other devices (like Chromecasts) and 360-degree video support for VR headsets.

Shotcut is open source free video editing software. It’s one of those open source programs that really demonstrates how much a dedicated development community can improve a platform given time. In earlier versions, the Shotcut interface was a little bare, but later releases have added extra dockable panels, an intuitive timeline, and other touches that put Shotcut in the same league as premium video editors like Adobe Premiere Pro.
This video tool supports non-destructive audio and video editing, meaning you can compile effects without any quality loss. You can also use this platform to do color keying and grading operations, as well as more basic clip splicing and trimming.
Perhaps the coolest thing about Shotcut is its ability to work with more or less any format of video, audio, or photo media. That’s largely thanks to FFmpeg, an open source video framework that sits under the hood of the Shotcut program.
If you don’t afford popular antivirus programs like Avira or Avast, then an open-source antivirus program like ClamWin might work for you. It’s a completely free antivirus program that is updated regularly. The antivirus is light, but it doesn’t come with real-time protection like other premium antiviruses.
Thankfully, you can schedule scans to make sure your PC is scanned routinely.
Notepad++ is a replacement for the Windows notepad app, which is a much more advanced text editor. I personally use Notepad++ to manage my notes and content ideas as it automatically saves all the changes offline, and numbered lines are extremely useful.
Although coders mostly use it to write code, most of its features help with coding, including auto-complete based on the current context.
Picking issues to work on and making contributions
Projects may list the work that needs to be done in task, bug, and issue trackers. For example, Angular uses Github’s project management feature to outline and assign tasks and track their progress. If a project has one, get access to it.
As a rule of thumb, start with the easiest and smallest contributions first that take the least amount of work to build up your confidence and credibility before trying harder contributions. Writing documentation and fixing typos is a good place to begin. Look for issues that are tagged for beginners with the tags mentioned earlier.
After you pick a task you think you can finish, do your research. Read documentation, code, and discussions related to the task to get a better understanding of what to do. If you’re stuck on something even after you’ve researched it, reach out to the community and ask for help, clarification, or mentorship. However, make sure that you discuss issues related to the task publicly so that the rest of the community can benefit from what you learn. For example, discuss an issue publicly on Github versus in a private direct message on Slack. Once you feel like you have enough context on a task and know how to go about it, write some code and submit a PR. Github has a great checklist about what to check for before you contribute to a project so your effort is not wasted.
Submitting your work
After you’ve completed work on your contribution, submit it as per the contribution guidelines. At times, your submission may not get a reply even after a reasonable amount of time has gone by. In such cases, respectfully request a review or get in touch with other contributors for assistance. Post-review changes may be requested. Try to make them as soon as possible so that your contribution is integrated promptly and does not become out-of-date or forgotten. If your contribution is rejected, ask for feedback to understand why. When reviewers ask questions, make comments, or give feedback, be responsive and check on your work for any updates regularly. Treat this like any other work and be professional, courteous, and respectful.
The best way to learn is by doing. With this book, you can make Android applications from scratch. You’ll start with the basics of Java programming and use the Android Studio integrated development environment (IDE) to build, test, and debug apps. Then you’ll publish your apps to Google Play. By the time you complete this book, you’ll be able to do everything necessary to make custom Android applications, including create an app that works on multiple devices.
