ccb0445027 Prepare for removal of legacy-test from default targets
In preparation for removing junit classes from the Android API
the legacy-test target will be removed from the
TARGET_DEFAULT_JAVA_LIBRARIES. This change adds explicit
dependencies on junit and/or legacy-android-test to ensure that
modules will compile properly once it is removed.

This is the same notification as the one shown during legacy lockdown

bccd8ad00a DO NOT MERGE: ConnectivityServiceTest: fix testAvoidBadWifiSettings
This patch introduces an assertEventuallyThat helper function in
ConnectivityServiceTest which given a boolean function retries until the
function returns true or until a maximum retry time is reached.

This function is used to fix flakyness of testAvoidBadWifiSetting where
the Message posted by reevaluate() could reach the Handler's
MessageQueue after waitForIdle takes effect, resulting in the test to
fail.

Instead of fixing the flakyness by introdcing hard sleep times,
assertEventuallyThat is used to reduce the overall test time.

With this change the test has been observed to pass with 100% success
rate over 50000 invocations.

de7002ef0d DO NOT MERGE: Fix ConnectivityServiceTest testRequestBenchmark
This patch fixes flakyness of testRequestBenchmark by adjusting time
limit for callback registration from 100ms to 180ms, and time limits for
onAvailable and onLost triggers from 30ms to 40ms.

With these timeouts the test succeeds 100% over 5000 iterations.

When using 150ms for registration timeout, running the test 5000 times
fails 2 times.

When using 30ms for onLost timeout, running the test 5000 times fails
1 times.

In addition, this patch also cleans testRequestBenchmark and uses the
more stable SystemClock.elapsedRealtime() for duration measurements.

144223318c DO NOT MERGE: Unbreak TetherInterfaceStateMachineTest.
This was broken by the implementation of IPv6 tethering, which
relies on various private classes which end up calling unmockable
final classes like NetworkInterface.

Making everything public like this is almost certainly not the
best way of fixing this test, but on the other hand there is
value to the test continuing to pass.

Test: runtest frameworks-net  # Everything passes.
Test: IPv6 tethering continues to work.

073e5e94ad DO NOT MERGE: De-guava BroadcastInterceptingContext and move it to testutils.
Removing the static dependency on guava reduces test compile time
by about 20 seconds on a Z840, thus substantially speeding up the
compile/test cycle.

Make FutureIntent public instead of package-private because it is
used directly by NetworkPolicyManagementServiceTest, which as of
this CL is now in a different package.

4e1619f034 ConnectivityServiceTest: some fixes in CallbackInfo

26c0dfed7a Support for WindowContainer controllers and listeners
- WindowContainerController class allows a component outside window manager
to create a window container and communicate directly with it to make
changes. For example, the ActivityRecord class in activity manager uses the
AppWindowContainerController class to create and communicate with
AppWindowToken window container class which is its counterpart on the window
manager side.
- WindowContainerListener interface allows a component outside WM to get
notified of changes to a window container. For example, the ActivityRecord
class in AM implements the AppWindowContainerListener interface to get
notified of changes to the AppWindowToken container.

fb2609d3ee Network notifications: revamp keying scheme
This patch changes the (tag: String, id: Int) keying scheme for network
notifications so that TRON notification counters can count network
related notifications unambiguously.

TRON instruments all notifications shown for package "android" as well
as user interactions with these Notifications. These counters are
grouped by id. However the network notifications ("no internet" dialog,
"captive portal sign in" dialog, ...) use a static tag and a dynamic id
for keying notifications, preventing the counters to correctly
aggregate. In addition there is also the risk of collision with other
SystemUi notification ids not managed by NetworkNotificationManager.

In order to make the TRON counters useful for network notifications,
the id is now encoding the network notification type in a stable way
while the tag is used to uniquely identify network notifications.

Test: change covered by previously added new unit tests.

53d83d5142 DO NOT MERGE: ConnectivityServiceTest: fix testAvoidBadWifiSettings
This patch introduces an assertEventuallyThat helper function in
ConnectivityServiceTest which given a boolean function retries until the
function returns true or until a maximum retry time is reached.

This function is used to fix flakyness of testAvoidBadWifiSetting where
the Message posted by reevaluate() could reach the Handler's
MessageQueue after waitForIdle takes effect, resulting in the test to
fail.

Instead of fixing the flakyness by introdcing hard sleep times,
assertEventuallyThat is used to reduce the overall test time.

With this change the test has been observed to pass with 100% success
rate over 50000 invocations.

cbf8ff83a8 DO NOT MERGE: Fix ConnectivityServiceTest testRequestBenchmark
This patch fixes flakyness of testRequestBenchmark by adjusting time
limit for callback registration from 100ms to 180ms, and time limits for
onAvailable and onLost triggers from 30ms to 40ms.

With these timeouts the test succeeds 100% over 5000 iterations.

When using 150ms for registration timeout, running the test 5000 times
fails 2 times.

When using 30ms for onLost timeout, running the test 5000 times fails
1 times.

In addition, this patch also cleans testRequestBenchmark and uses the
more stable SystemClock.elapsedRealtime() for duration measurements.

f99a33a1b4 DO NOT MERGE: IpConnectivityMetrics: rate limit ApfProgramEvents
This patch uses the previously introduced TokenBucket to rate limit
ApfProgramEvents, still allowing for burst of ApfProgramEvents when a
new interface is set up (due to ipv4 provisioning, multicast lock, ipv6 RAs
triggering new APF program events in short amounts of time).

Test: new test in IpConnectivityMetricsTest
