 ## Building
 
 There are multiple ways to get the native syncthing binary:
+- open a syncthing apk running on your device as a zip, extract the `lib/` folder into your project directory and rename it to `libs/`.
 - Depending on your target architecture, download `syncthing-linux-386`, `syncthing-linux-armv5`, `syncthing-linux-armv7` or `syncthing-linux-mips` from [syncthing releases](https://github.com/calmh/syncthing/releases), and extract the binary to `libs/x86/libsyncthing.so`, `libs/armeabi-v7a/libsyncthing.so`, `libs/armeabi/libsyncthing.so` or `libs/mips/libsyncthing.so` respectively.
 - Set up a syncthing compile and run `gradle buildNative` in your syncthing-android directory.
