From e5b77a812f222eb7721881dac80c5455307a8126 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Sat, 23 May 2026 22:02:19 +0300 Subject: [PATCH 01/14] Add deeper network connectivity APIs: WiFi info / scan / connect, Bonjour, WiFi Direct, USB, network type events New core API surface under com.codename1.io.{wifi,bonjour,usb} plus NetworkManager.addNetworkTypeListener. Each API surface is implemented on Android (WifiManager / NsdManager / WifiP2pManager / UsbManager / ConnectivityManager), iOS (CaptiveNetwork / NEHotspotConfiguration / NSNetService / SCNetworkReachability), and JavaSE (best-effort NetworkInterface + simulated scan results + JmDNS hook). The maven plugin builders auto-inject the matching Android permissions (ACCESS_WIFI_STATE, CHANGE_WIFI_STATE, ACCESS_NETWORK_STATE, CHANGE_NETWORK_STATE, ACCESS_FINE_LOCATION, NEARBY_WIFI_DEVICES, CHANGE_WIFI_MULTICAST_STATE, usb.host feature) and iOS entitlements/Info.plist strings (wifi-info, HotspotConfiguration, NSLocalNetworkUsageDescription, NSBonjourServices) only when the relevant classes are referenced from the classpath -- so apps that never touch these APIs see no manifest, entitlement, or Info.plist change. The Objective-C native bridge is gated by CN1_INCLUDE_WIFI_INFO, CN1_INCLUDE_HOTSPOT, and CN1_INCLUDE_BONJOUR defines that IPhoneBuilder flips on only when the corresponding API surface is referenced. Stock apps therefore ship without any CaptiveNetwork, NetworkExtension, or NSNetServiceBrowser symbols and pass Apple's API-usage scan cleanly. The simulator prints a one-shot warning the first time each API is called, listing the permissions/entitlements production builds will need; a JVM shutdown hook summarises everything used during the run. Documented in docs/developer-guide/Network-Connectivity.asciidoc.

Instead each new API group has a narrow platform interface (WifiPlatform, WifiDirectPlatform, BonjourPlatform, UsbPlatform, NetworkTypePlatform) obtained from Display.getInstance().getXxxPlatform(). CodenameOneImplementation only carries small createXxxPlatform() factories; each port returns its concrete subclass, so the base implementation stays modular. 2) Old-device safety: AndroidConnectivity held static fields of type ConnectivityManager.NetworkCallback (API 21) which would fail class verification on KitKat (minSdkVersion 19). The Lollipop-only bits now live in *Lollipop helper classes that are only referenced from inside Build.VERSION.SDK_INT guards, so the KitKat verifier never loads them. 3) NetworkManager.isConnected(): cheap EDT-safe reachability check that returns false only when NETWORK_TYPE_NONE, avoiding the HTTP probe against autoDetectURL. 4) Documentation: - Drop the version "Codename One 8" mention. - Clarify JmDNS belongs in the application's executable-jar / simulator profile, not in the cn1app common pom (which would ship JmDNS to devices that already have native mDNS). - Replace the deinitializeImpl() lifecycle note with a battery- drain warning -- deinitializeImpl is internal API and shouldn't show up in developer docs. - Add a quick-check example for NetworkManager.isConnected(). 5) SpotBugs exclusion comment: rewrite the rationale to explain why LI_LAZY_INIT_* doesn't apply (EDT-bound install pattern, no actual race) instead of just "matches existing convention".
