How do I see if Wi-Fi is connected on Android?

Question

I don\'t want my user to even try downloading something unless they have Wi-Fi connected. However, I can only seem to be able to tell if Wi-Fi is enabled, but they could sti

Answer 1

I simply use the following:

SupplicantState supState; 
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
supState = wifiInfo.getSupplicantState();

Which will return one of these states at the time you call getSupplicantState();

ASSOCIATED - Association completed.

ASSOCIATING - Trying to associate with an access point.

COMPLETED - All authentication completed.

DISCONNECTED - This state indicates that client is not associated, but is likely to start looking for an access point.

DORMANT - An Android-added state that is reported when a client issues an explicit DISCONNECT command.

FOUR_WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress.

GROUP_HANDSHAKE - WPA Group Key Handshake in progress.

INACTIVE - Inactive state.

INVALID - A pseudo-state that should normally never be seen.

SCANNING - Scanning for a network.

UNINITIALIZED - No connection.
