- Remove static text from default app summaries.They will be filled dynamically at runtime, so we don't need the static ones here. - Remove summaryOn/summaryOff strings from a few fragments. Search framework does not need them. Change-Id: I165766073ba70aceead88c3df02d62f3700e4592 Fix: 36474747 Fix: 34573952 Test: run existing tests
