@ -27,18 +27,9 @@ Make sure you clone the project with
|
|||
`git clone https://github.com/syncthing/syncthing-android.git --recursive`. Alternatively, run
|
||||
`git submodule init && git submodule update` in the project folder.
|
||||
|
||||
Build Syncthing using `./syncthing/build-syncthing.bash`. Then use `./gradlew assembleDebug` or
|
||||
Build Syncthing using `./gradlew buildNative`. Then use `./gradlew assembleDebug` or
|
||||
Android Studio to build the apk.
|
||||
|
||||
### Building on Windows
|
||||
|
||||
To build the Syncthing app on Windows we need to have cygwin installed.
|
||||
|
||||
From a cygwin shell in the project directory, build Syncthing using `./syncthing/build-syncthing.bash`
|
||||
|
||||
Lastly, use `./gradlew assembleDebug` in the project directory to compile the APK, or use Android
|
||||
Studio to build/deploy the APK.
