AB-Test for Android You have an application, which is probably publicly available. Send an amount of users to another variant than the normal one. Depending on success ratio you have the best suiting solution. Page 11 moosecon 2013 | Customers Choice | Hasan Hosgel

Developers Todo List Create switches depending on the business logic Create a proprietary solution Not reusable Publish application Waiting for the results Remove switches and republish application Waiting that everybody updates to the new version Page 13 moosecon 2013 | Customers Choice | Hasan Hosgel
Smarter Solution The library Customers Choice with a common approach
Customers Coice A lightweight Open Source Android library making simple AB-Tests in an application, which can be configured over the network. Possible AB-Tests variants: For layouts and positions For colors For workflows For texts https://github.com/alosdev/CustomersChoice Page 15 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Add the library (*.jar) to your project Configure your switch based on the variant CustomersChoice.getVariant(context,VariantName); When you reach your expected goal, report it CustomersChoice.reachesGoal(VariantName); done Page 16 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? Page 17 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? No Page 18 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? No Will it have full functionality? Page 19 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? No Will it have full functionality? Not really Page 20 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? No Will it have full functionality? Not really Why? Page 21 moosecon 2013 | Customers Choice | Hasan Hosgel
Usage Will an exception be raised? No Will it have full functionality? Not really Why? It is not configured, therefore #getVariant(String) will always return variant 1 for the given variant name Page 22 moosecon 2013 | Customers Choice | Hasan Hosgel
Configuration of Variants Through code JSON String in resources Configuration file on SD card Configuration file in the network with standard caching mechanism, like Etag- and Modified Since Header For testing purposes you can overwrite a variant with a broadcast intent Page 23 moosecon 2013 | Customers Choice | Hasan Hosgel
Variants Attributes name: String (required) startTime: Integer in Milliseconds endTime: Integer in Milliseconds spreading: Integer array for ratio of different variants reset: Boolean for resetting the current value {variants:[{ name:VariantName, startTime:768997, endTime:1022222, spreading:[1,2,1], reset:true}, {} ,]} Global Attribute: resetAll reset all variants Page 24 moosecon 2013 | Customers Choice | Hasan Hosgel
Extensibility You can write custom plugins for: Logging Reporting You can fork the library on Github, make your changes and send a pull request. https://github.com/alosdev/CustomersChoice Page 25 moosecon 2013 | Customers Choice | Hasan Hosgel
