In the simulator for SDK 4,2.4, running the Instinct Crossover, it reports that monkey version 3.4.0 is being used. When a valid string property is read, using AppBase.getProperty(key), an empty string is always returned instead of the set string value. Also, boolean properties are not always read properly. The opposite of the set value is sometimes read. Also for number properties it seems to return the default value and not the set value.
