Example 46 with ProxyInfo

use of android.net.ProxyInfo in project android_frameworks_base by DirtyUnicorns.

the class ConnectivityService method updateProxy.

// If the proxy has changed from oldLp to newLp, resend proxy broadcast with default proxy.
// This method gets called when any network changes proxy, but the broadcast only ever contains
// the default proxy (even if it hasn't changed).
// TODO: Deprecate the broadcast extras as they aren't necessarily applicable in a multi-network
// world where an app might be bound to a non-default network.
private void updateProxy(LinkProperties newLp, LinkProperties oldLp, NetworkAgentInfo nai) {

Example 47 with ProxyInfo

use of android.net.ProxyInfo in project android_frameworks_base by DirtyUnicorns.

the class NetworkMonitor method isCaptivePortal.

@VisibleForTesting
protected CaptivePortalProbeResult isCaptivePortal() {
    if (!mIsCaptivePortalCheckEnabled) {
        validationLog("Validation disabled.");
        return new CaptivePortalProbeResult(204);

    URL pacUrl = null, httpsUrl = null, httpUrl = null, fallbackUrl = null;
    // On networks with a PAC instead of fetching a URL that should result in a 204
    // response, we instead simply fetch the PAC script.  This is done for a few reasons:
    // 1. At present our PAC code does not yet handle multiple PACs on multiple networks
    //    until something like https://android-review.googlesource.com/#/c/115180/ lands.
    //    Network.openConnection() will ignore network-specific PACs and instead fetch
    //    using NO_PROXY.  If a PAC is in place, the only fetch we know will succeed with
    //    NO_PROXY is the fetch of the PAC itself.
    // 2. To proxy the generate_204 fetch through a PAC would require a number of things
    //    happen before the fetch can commence, namely:
    //        a) the PAC script be fetched
    //        b) a PAC script resolver service be fired up and resolve the captive portal
    //           server.
    //    Network validation could be delayed until these prerequisities are satisifed or
    //    could simply be left to race them.  Neither is an optimal solution.
    // 3. PAC scripts are sometimes used to block or restrict Internet access and may in
    //    fact block fetching of the generate_204 URL which would lead to false negative
    //    results for network validation.
