don't try to set action bar icon if fragment is not attached
update color-picker
Add analytics. The SDK now has a couple of methods to enable, record and send analytics data. Analytics are anonymous, so it's not possible to identify a user by the data sent.
Analytics are disabled by default in the SDK. However, the UI, by default, enables it on startup.
The current version is not going to be published until the user has an option to disable analytics.
