1 year ago Heh, I was never actually solved this properly.
First off, you need to cross-compile a libusb.so (it's just cd libusb/android; $ANDROID_NDK_HOME/ndk-build libs/armeabi-v7a/libusb1.0.so APP_ABI=armeabi-v7a APP_PLATFORM=android-$API)
Then I use a file called fake-pk-config.sh with these contents:
if [[ "$1" == "--libs" && "$2" == "--cflags" ]]; then
case "$3" in
"libusb-1.0")
echo "-I$BASE_DIR/libusb/libusb -L$BASE_DIR/libusb/android/libs/armeabi-v7a -lusb1.0"
;;
*)
echo "Unsupported lib" >&2
exit 1
;;
esac
elif [[ "$1" == "--modversion" ]]; then
case "$2" in
"libusb-1.0")
echo "1.0.26"
;;
*)
echo "Unsupported lib" >&2
exit 1
;;
esac
else
echo "Unsupported args." >&2
exit 1
fiAnd export PKG_CONFIG="$BASE_DIR/fake-pkg-config.sh". You could probably make the actual pkg-config work properly (with the PKG_CONFIG* env vars and creating a libusb.pc file), but I never really cared :P
An alternative would be properly implementing https://github.com/badicsalex/tiny-linux-usb and then using that instead of both rusb and hidapi. I did try it with the nreal air driver, and it can be made to work on Android, but it'd take at least a week of real work.

Running
cargo build --target aarch64-linux-android --verbosegivesI went through this https://github.com/ruabmbua/hidapi-rs/issues/122 issue too, to find any hints but alas.
My env looks something like this:
And
.cargo/configlooks like this:
