v2.0.0

This is a major release. Default behaviors surrounding sessions have changed. Many bugs have also been addressed.

• Expose user ID with getUserId.
• Simplified session tracking. No longer need to call startSession and endSession. No longer send start/end session events by default. Added foreground tracking for sessions that uses Android activity lifecycles.
• The minimum supported API level is 9. API level 14 is required for foreground tracking.
• Always track Android advertising ID (ADID) regardless of limit ad tracking enabled.
• Track if limit ad tracking enabled as an API property for each logged event.
• Database upgraded to version 2: added a new store table for key value pairs.
• Device ID is now saved to and reloaded from the SQLite database (instead of SharedPrefs because SharedPrefs currently does not support multiple processes).
• MessageDigest.getInstance(String) is not threadsafe (known Android issue). Replaced with alternate MD5 implementation from http://org.rodage.com/pub/java/security/MD5.java.
• Create a copy of input userProperties JSONObject in setUserProperties to try and prevent ConcurrentModificationException.
