da6da0907b28d4704aabbdb1bbeb4300954670d1 16-Aug-2012 Irfan Sheriff <isheriff@google.com> Captive portal handling

We now notify the user of a captive portal before switching to the network as default.
This allows background applications to continue to work until the user confirms he
wants to sign in to the captive portal.

Also, moved out captive portal handling out of wifi as a seperate component.

When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).

We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.

ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data

Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

c006f1aec15454782c35e028ad64d79a5c161cc1 20-May-2011 Jeff Sharkey <jsharkey@android.com> Policy and rules work for ConnectivityManager.

Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all

Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.

to have NetworkStateTracker as an interface.

Mark cellular variants with the same availability, regardless of which are currently in use.
Availability just means the radio is enabled and sees the network, but has no guarantees that
we could connect to an APN if requested.

Fix the requestRouteToHost logic to support apn switches without WIFI.
