Are you interested in syncing your files seamlessly across devices using Syncthing on your Android device? This guide will walk you through how to set up, build, and maintain the Syncthing app on Android, while also providing you with troubleshooting tips to optimize your experience.

What is Syncthing?

Syncthing is an open-source file syncing application that facilitates peer-to-peer file synchronization. This is especially helpful for those who prioritize privacy and wish to avoid cloud storage solutions.

Prerequisites for Building Syncthing

Before we begin, you’ll need to ensure that you have the right dependencies installed on your system:

• Android SDK and NDK
• Go Programming Language
• Java (version 11)
• Python (version 3)

Setting Up the Android SDK and NDK

Follow these steps to set up your Android SDK and NDK:

1. Download the SDK command line tools from here.
2. Unpack the downloaded archive to an empty folder and name it as your ANDROID_HOME.
3. Create a folder called latest inside the unpacked cmdline-tools folder, and move everything else into it.
4. Navigate to the latest/bin folder and execute:

   .sdkmanager platform-tools build-tools;version platforms;android-version extras;android;m2repository ndk;version

The required tools and NDK will now be downloaded automatically. Make sure to refer to the Dockerfile for specific version numbers to input in the command above.

Building Syncthing

Now that you have set up your environment, let’s build the Syncthing application!

1. Clone the project repository with:

   git clone https://github.com/syncthing/syncthing-android.git --recursive

2. If the repository is already present, just navigate to the project folder and run:

   git submodule init
   git submodule update

3. Make sure the ANDROID_HOME variable points to the SDK path.
4. Navigate to the syncthing-android folder and execute the build commands:

   ./gradlew buildNative 
   ./gradlew assembleDebug

Upon completion, the APK file will be available in app/build/outputs/apk/debug.

Troubleshooting Tips

If you encounter an issue during the installation or building process, consider the following:

• Ensure that you have the required versions of Java, Go, and Python installed.
• Make sure that you use the Command Prompt on Windows and not PowerShell when compiling.
• Check if the ANDROID_HOME variable is correctly set.
• If errors persist, review the console output as it can provide hints about what went wrong.
