assistant: The easiest way is to use a pre-existing tool to do the conversion.

assistant: public interface IBase extends android.os.IHwInterface {
    public static final String kInterfaceName = "android.hidl.base@1.0::IBase";

    public static IBase asInterface(android.os.IHwBinder binder) {
        if (binder == null) {
            return null;
        }

        android.os.IHwInterface iface = binder.queryLocalInterface(kInterfaceName);
        if (iface != null && iface instanceof IBase) {
            return (IBase) iface;
        }

        IBase proxy = new IBase.Proxy(binder);
        try {
