From 7b69897b6c670f9bf5a9a2112459620245b99b5e Mon Sep 17 00:00:00 2001 From: Justin Fiedler Date: Mon, 25 Mar 2024 11:59:06 -0700 Subject: [PATCH] fix: start tracking sessions at init for session replay (#186) * fix: start tracking sessions at init for session replay * fix: support adding plugins to initial config * chore: centralize time to use SystemTime for easier testing * chore: test sessionId is the time of instantiation after isBuilt * chore: added mockSystemTime() util for testing * fix: add tests for ObservePlugin.onSessionIdChanged * fix: override amplitude by default in ObservePlugin * chore: remove unneeded session logic in Timeline.process --- .github/workflows/pull-request-test.yml | 4 + .../java/com/amplitude/android/Amplitude.kt | 20 +-
