kiosk-usb-reset

Compiling

This does something, maybe nothing, posting it here just it case. Probably don't run it unless you figure out you need it and in what folder to run it. Probably inside Android Studio folder. Building for android most probably needs this though. Stackoverflow knows. android-ndk-r10e/build/tools/make-standalone-toolchain.sh --platform=android-18 --toolchain=aarch64-linux-android-clang3.6 --install-dir=android-18-toolchain --ndk-dir=android-ndk-r10e/ --arch=arm

Install Android target platform:

rustup target add aarch64-linux-android

Then compile for Android:

cargo build --target=aarch64-linux-android

Running

After compiling for Android you need to move it to the tablet and execute. Files cannot execute in SD card so move it to local fs.

1. adb push kiosk-usb-reset /sdcard/Download
2. adb shell
3. su
4. cp /sdcard/Download/kiosk-usb-reset /data/local/tmp/
5. cd /data/local/tmp
6. ./kiosk-usb-reset

Permanent install

All of this assumes SElinux is disabled or set to warning-mode-only, which it is on our manufacturing sample.
