+ * * `servicePort` (`service.adb.tcp.port`)
+ * * `persistPort` (`persist.adb.tcp.port`)
+ *
+ * Once it finds a non-empty value, it will use it and ignore the rest.
+ *
+ * `serviceListenAddresses` and `persistPort` are fixed at build time,
+ * only `servicePort` can be changed using `setPort` and `disable`.
+ * This means if either `serviceListenAddresses` or `persistPort` is non-empty,
+ * ADB over WiFi is always enabled.
