Android rsync Builds

Build script to cross-compile rsync for Android.

Precompiled Binaries

armv7a, aarch64, i686 and x86_64 Android binaries compiled under GitHub Actions are available as release assets from this repository.

There is a JAR release asset containing all of the binaries (renamed to librsync.so to allow them to be executed from within an Android app). This is also available as a package for ease of use as a dependency in Android Studio.

Manual Build

• Ensure that the Android NDK is located at $ANDROID_NDK_HOME or $ANDROID_HOME/ndk-bundle.
• Run ./build

Example Usage

From an Android app with the published package added as a dependency:

val libDir = context.applicationInfo.nativeLibraryDir

val args = ArrayList<String>()
args.add("$libDir/librsync.so")
args.add("--version")

val builder = ProcessBuilder(args)
val rsync = builder.start()

val result = rsync.waitFor()
val stdout = rsync.inputStream.bufferedReader().use(BufferedReader::readText)
val stderr = rsync.errorStream.bufferedReader().use(BufferedReader::readText)

Log.d(TAG, "Exit code: $result")
Log.d(TAG, "Standard out: $stdout")
Log.d(TAG, "Standard error: $stderr")
