- less strict regex for SharedLogTest: the subsecond part of the timestamp can have 0, 1, 2 or 3 digits. - refactor NetworkStatsServiceTest and NetworkStatsObserversTest to use waitForIdleHandler facility of ConnectivityServiceTest. NetworkStatsServiceTest was using a flaky custom version of waitForIdleHandler. Bug: 62918393 Bug: 32561414 Test: runtest frameworks-net Change-Id: I634acfb5f4fe1bd5267e3f14b9f645edc32d5d12
