# Native Bridge Support in ReDroid

There are several choose to support native bridge (typically for arm) in *ReDroid*
- `libndk_translation` from Arm
- `libhoudini` from Intel
- `QEMU`

Prepare the resource and build the image.
And run `docker build --build-arg BASE_IMAGE=<Base Image> .`

```bash
# example structure, be careful the file owner and mode

system/

# grab libndk_translation from Android 11 Emulator
find /system \( -name 'libndk_translation*' -o -name '*arm*' -o -name 'ndk_translation*' \) | tar -cf native-bridge.tar -T - 

```
