How to Use Open Source Code for Android

Open source code allows the developer to create an innovative application; however, the use of such code is hampered by difficulties in navigating the source code and applying it to one’s application. This article is intended to provide both novice and advanced users with an overview of how to use open source code for their Android applications.

  It is possible that you have used Open Source Code for Android and do not know it. Many things in your phone depend on a software component called the “Android Framework”.  If you’re looking to take advantage of Open Source, whether for philosophical or security reasons, or maybe just because it’s free and works, this page will walk through some of the basics: what is open-source code? where can you find it? why should you care? how is it different from regular code? how do you use it? Which applications are out there running open-source components that I may already be using now? Some phones run more open-source than others. While many people may think of Android as an open-source operating system, little gets done without the contributions of many developers.

Importing Source Code into Android Studio

You can download the source code for your Dropsource project at any time. Select Deploy this Build for the relevant build in your Builds list in the editor, then select Download Source Code. Once downloaded you can import your code into the Android Studio IDE. Your download will be in a zipped archive file, so unzip it before continuing.

Before Importing

ⓘ Note

If you edit the source code for your app outside of Dropsource there is no way to import your changes back into the editor.

Similarly, if you make any additional changes to a project inside Dropsource after importing it into your IDE, you will need to download and import the updated code into your IDE again.

Your source code download is a reflection of your app at the time of your last build inside Dropsource, made available for a one-way transfer to the IDE. However, if you plan to release multiple versions of your app you can do so from your source code – for each new version:

  • Make your changes in the editor.
  • Build your project.
  • Download the source code.
  • Import it into your IDE.
  • Export for release.

If you don’t make any changes to the source code outside Dropsource, you can continue delivering future versions from Dropsource via your IDE using this method. If you do make changes outside Dropsource, you will need reapply those changes each time you download your source code from the platform. If you don’t need to make any changes to your Dropsource project in an IDE, you can request the Dropsource publishing service to have your app launched without the need to download your code at all.


Telegram - Best open-source Android apps

Telegram is one of the mostly used encrypted instant messaging service available for Android and iOS. Learn from the Telegram code — how an instant messaging app with super security works.

Importing into Android Studio

Open Android Studio and select Open an Existing Android Studio Project or FileOpen. Locate the folder you downloaded from Dropsource and unzipped, choosing the “build.gradle” file in the root directory.

build gradle

Android Studio will import the project. You may see warnings or errors regarding SDK and Android versions – if so click the links in the messages to set up your installation of Android Studio with the required versions and components.

Select Project on the left side to view and explore the files in your app.

Open the “res/layout” directory to access the UI configuration for the app, including pages and other layout components. Select an XML file with the name of one of the pages you created in Dropsource to view it graphically.

Select the Text tab to view the XML markup code for your layout.

In the “java/<package-name>/activities” directory you will find the Java programming code for each of your app pages, with additional functionality defined in the other Java files in the directory.

Click the Run button to run the app – if you have not already created an Android emulator, Android Studio will prompt you to do so at this point. Once you have an emulator, select it to launch your app on it.

Android Studio will run your app on the emulator.

Make sure you don’t spend too much time working on your app in Android Studio if you still need to work on it in the Dropsource editor, as your local changes will not be reflected in Dropsource.


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. The main plus point of this app is its “extended privacy” — NewPipe protects user privacy since no proprietary Google APIs is there in the code and only send information which are required to get video and channel details.

  • Google Play: Not Available
  • Source code: GitHub

Extending and Customizing

If you are willing to write the required Java, XML, or other code to make alterations, you can do so with your source code download imported into Android Studio. You can extend the functionality defined in Dropsource with SDKs and other options not supported inside the editor – however, if you do require functionality that is not available in Dropsource, you may be able to achieve it using a plugin.
