+ /*
+ * Note for maintainers about how PAC proxies are implemented in Android.
+ *
+ * Generally, a proxy is just a hostname and a port to which requests are sent, instead of
+ * sending them directly. Most HTTP libraries know to use this protocol, and the Java
+ * language has properties to help handling these :
+ * https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html
+ * Unfortunately these properties are very old and do not take multi-networking into account.
+ *
+ * A PAC proxy consists of a javascript file stored on a server, and the client is expected to
+ * download the file and interpret the javascript for each HTTP request to know where to direct
+ * it. The device must therefore run code (namely, a javascript interpreter) to interpret the
+ * PAC file correctly. Most HTTP libraries do not know how to do this, since they do not
+ * embark a javascript interpreter (and it would be generally unreasonable for them to do
+ * so). Some apps, notably browsers, do know how to do this, but they are the exception rather
+ * than the rule.
+ * So to support most apps, Android embarks the javascript interpreter. When a network is
+ * configured to have a PAC proxy, Android will first set the ProxyInfo object to an object
+ * that contains the PAC URL (to communicate that to apps that know how to use it), then
+ * download the PAC file and start a native process which will open a server on localhost,
+ * and uses the interpreter inside WebView to interpret the PAC file. This server takes
+ * a little bit of time to start and will listen on a random port. When the port is known,
+ * the framework receives a notification and it updates the ProxyInfo in LinkProperties
+ * as well as send a broadcast to inform apps. This new ProxyInfo still contains the PAC URL,
+ * but it also contains "localhost" as the host and the port that the server listens to as
+ * the port. This will let HTTP libraries that don't have a javascript interpreter work,
+ * because they'll send the requests to this server running on localhost on the correct port,
+ * and this server will do what is appropriate with each request according to the PAC file.
+ *
+ * Note that at the time of this writing, Android does not support starting multiple local
+ * PAC servers, though this would be possible in theory by just starting multiple instances
+ * of this process running their server on different ports. As a stopgap measure, Android
+ * keeps one local server which is always the one for the default network. If a non-default
+ * network has a PAC proxy, it will have a LinkProperties with a port of -1, which means it
+ * could still be used by apps that know how to use the PAC URL directly, but not by HTTP
+ * libs that don't know how to do that. When a network with a PAC proxy becomes the default,
+ * the local server is started. When a network without a PAC proxy becomes the default, the
+ * local server is stopped if it is running (and the LP for the old default network should
+ * be reset to have a port of -1).
+ *
+ * In principle, each network can be configured with a different proxy (typically in the
+ * network settings for a Wi-Fi network). These end up exposed in the LinkProperties of the
+ * relevant network.
+ * Android also exposes ConnectivityManager#getDefaultProxy, which is simply the proxy for
+ * the default network. This was retrofitted from a time where Android did not support multiple
+ * concurrent networks, hence the difficult architecture.
+ * Note that there is also a "global" proxy that can be set by the DPM. When this is set,
+ * it overrides the proxy settings for every single network at the same time – that is, the
+ * system behaves as if the global proxy is the configured proxy for each network.
+ *
+ * Generally there are four ways for apps to look up the proxy.
+ * - Looking up the ProxyInfo in the LinkProperties for a network.
+ * - Listening to the PROXY_CHANGED_ACTION broadcast
+ * - Calling ConnectivityManager#getDefaultProxy, or ConnectivityManager#getProxyForNetwork
+ * which can be used to retrieve the proxy for any given network or the default network by
+ * passing null.
+ * - Reading the standard JVM properties (http{s,}.proxy{Host,Port}). See the Java
+ * distribution documentation for details on how these are supposed to work :
+ * https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html
+ * In Android, these are set by ActivityThread in each process in response to the broadcast.
+ * Many apps actually use these, and it's important they work because it's part of the
+ * Java standard, meaning they need to be set for existing Java libs to work on Android.
