Android SDK 2.4.3.1946

[added]Added New initSDKwithoutVisitor APIs that we recommend using in the common case when the visitorId is not known at the time the SDK is initialized. The visitorId can be set later via switchVisitor.

• Use initSdkWithoutVisitor in Application::onCreate method.
• Use  switchVisitor  in Activity::onCreate method

addedAdded A new endSession API was added to support applications running as an Android Service. This API should be called in the service’s onTaskRemoved method. It will clean the Pendo session while the application keeps running.
