With ourmost recent update (v17.1.4), the easiest way to integrate Logify within an XAF app is to use the LogifyAlertTraceListener API. You will find common and platform-dependent integration instructions for this recommended approach in the the following KB article https://www.devexpress.com/kb=T474018
Please note that we are using this exact approach for our online Web and Mobile demos (available at https://www.devexpress.com/Products/NET/Application_Framework/demos.xml). As you would expect, using Logify helps us improve product stability and product quality for both XAF's Mobile UI (CTP) platform and associated demo apps https://demos.devexpress.com/XAF/MainDemoMobile.
Logify itself is also widely used to deliver crash reports in other demos, runtime and design time tools for many DevExpress products and technologies:
Feel free to contact us if you're already using Logify (the product is currently an invitation only beta) and want to try this new approach. We will be more than happy to provide you with the assistance needed to get started.
