This is an unofficial reimplementation of Linux Mint's file sharing tool Warpinator for Android.
Get the APK from the Releases page
Also available on F-Droid and Google Play
Build with Android Studio or with this command (you will need to install Android SDK yourself though):
export ANDROID_SDK_ROOT=$HOME/Android/Sdk
./gradlew :app:assembleDebug
Warpinator for Android can be translated just like any other Android application. Just copy strings.xml from /app/src/main/res/values to /app/src/main/res/values-xx where xx is the code of the language you are translating to. Then translate everything in the new xml file and submit a PR.
