【Android】NetworkInfo.StateとNetworkInfo.DetailedStateとSupplicantStateの関係

Android

AndroidでWifiの状態を知りたいなーと思ったら、いろいろなStateがあるらしい。。
対応関係がわからないな...と思ったので調べてみたときの備忘録。

対応関係はこんな感じ。SupplicantStateだと、
NetworkInfo.StateのCONNECTEDとSUSPENDEDに当たるものがないので注意。

NetworkInfo.State	NetworkInfo.DetailedState	SupplicantState
DISCONNECTED	IDLE	INACTIVE
		UNINITIALIZED
	SCANNING	SCANNING
CONNECTING	CONNECTING	AUTHENTICATING
		ASSOCIATING
		ASSOCIATED
	AUTHENTICATING	FOUR_WAY_HANDSHAKE
		GROUP_HANDSHAKE
	OBTAINING_IPADDR	COMPLETED
CONNECTED	CONNECTED	-
SUSPENDED	SUSPENDED	-
DISCONNECTING	DISCONNECTING	-
DISCONNECTED	DISCONNECTED	DISCONNECTED
		INTERFACE_DISABLED
		DORMANT
	FAILED	INVALID

NetworkInfo.DetailedStateとNetworkInfo.Stateの対応

core/java/android/net/NetworkInfo.java - platform/frameworks/base - Git at Googleより

stateMap.put(DetailedState.IDLE, State.DISCONNECTED);
stateMap.put(DetailedState.SCANNING, State.DISCONNECTED);
stateMap.put(DetailedState.CONNECTING, State.CONNECTING);
stateMap.put(DetailedState.AUTHENTICATING, State.CONNECTING);
stateMap.put(DetailedState.OBTAINING_IPADDR, State.CONNECTING);
stateMap.put(DetailedState.CONNECTED, State.CONNECTED);
stateMap.put(DetailedState.SUSPENDED, State.SUSPENDED);
stateMap.put(DetailedState.DISCONNECTING, State.DISCONNECTING);
stateMap.put(DetailedState.DISCONNECTED, State.DISCONNECTED);
stateMap.put(DetailedState.FAILED, State.DISCONNECTED);

SupplicantStateとNetworkInfo.DetailedStateの対応

wifi/java/android/net/wifi/WifiInfo.java - platform/frameworks/base - Git at Googleより

stateMap.put(SupplicantState.DISCONNECTED, DetailedState.DISCONNECTED);
stateMap.put(SupplicantState.INTERFACE_DISABLED, DetailedState.DISCONNECTED);
stateMap.put(SupplicantState.INACTIVE, DetailedState.IDLE);
stateMap.put(SupplicantState.SCANNING, DetailedState.SCANNING);
stateMap.put(SupplicantState.AUTHENTICATING, DetailedState.CONNECTING);
stateMap.put(SupplicantState.ASSOCIATING, DetailedState.CONNECTING);
stateMap.put(SupplicantState.ASSOCIATED, DetailedState.CONNECTING);
stateMap.put(SupplicantState.FOUR_WAY_HANDSHAKE, DetailedState.AUTHENTICATING);
stateMap.put(SupplicantState.GROUP_HANDSHAKE, DetailedState.AUTHENTICATING);
stateMap.put(SupplicantState.COMPLETED, DetailedState.OBTAINING_IPADDR);
stateMap.put(SupplicantState.DORMANT, DetailedState.DISCONNECTED);
stateMap.put(SupplicantState.UNINITIALIZED, DetailedState.IDLE);
stateMap.put(SupplicantState.INVALID, DetailedState.FAILED);
