I'm attempting to expand our basic implementation of the Marketing Cloud SDK in our Android app. We've successfully been using it to send push notifications, and are now adding some attributes so we can better target them.
Following the documentation here: http://salesforce-marketingcloud.github.io/JB4A-SDK-Android/features/attributes.html with version 5.3.0 of the marketing cloud SDK I attempted to create a new Attribute object using the static create method contained within.
Attribute attr = Attribute.create("key", "value");
However, Android Studio is complaining that the method doesn't exist, and asking it to open the source for the Attribute class does not show the method in the decompiled class.
Am I being prevented from using this method due to a proguard configuration or is there something else preventing the method from showing up in 5.3.0?
