- getNonIndexableKeys(Context) allow a SearchIndexProvider to tell which data he does not want to index by providing a list of the data keys - use this new API for SoundSettings and removing KEY_EMERGENCY_TONE related settings if the device is not CDMA - add a BaseSearchIndexProvider for code simplification Change-Id: I23633ace1d7e390ee05fac0a5458a33e04e72d8d
