Path to be used for caching purposes. It should be a path to the desired location where the application has read/write permissions. The path can be on internal or external storage. By default, this returns an empty string. Setting a new string, will overwrite the internally used default paths:

<Application_Home>/Library/Caches for iOS and Context.getCacheDir().getPath() for Android. If an absolute path is set, it will be used instead. If a relative path is set then directory <Application_Home>/Library/Caches for iOS and Context.getCacheDir().getPath() for Android is used as parent path.
