I could just ignore such warnings, by adding-ignorewarningsin proguard-rules.pro, but this is not recommended because future warnings will also be caught by this rule. ProGuard can also remove logging code, from applications and their libraries, without needing to change the source code in fact, without needing the source code at all! Starting from the HelloFX sample, the build will be modified to: // 1. I understand this is part of theandroidx.lifecycle, which checks for the existence of such classes and handles their absence.

I build and run the application with this new ProGuard configuration, testing all application functionalities to make sure that debug suggestions have covered all code paths. I dont need to add such a rule in the configuration file. This is very useful to get practical hints at run-time, for cases where the processed code crashed because it still lacked some configuration for reflection. I update the -keep rule by considering any number of parameters: The Proguard Playground shows that it will fix this issue. The resulting apk size is 13.5MB, and executing the application shows that its working correctly on-device. This is very useful to get practical hints at run-time, for cases where the processed code crashed because it still lacked some configuration for reflection.

My first attempt at building the application resulted in many warning messages like this one: The ProGuard documentation (see https://www.guardsquare.com/manual/troubleshooting) provides the reason for this: "A class in one of your program jars or library jars is referring to a class or interface that is missing from the input. ProGuard doesn't have this knowledge and will warn about this, so I have to explicitly tell it that these missing classes are fine (see the ProGuard user's manual about the-dontwarnoption). If the missing class is referenced from your own code, you may have forgotten to specify an essential library.

Remark that the keep option is mandatory, we use this default class Resource - [Tutorial] How to obfuscate a plugin using ProGuard | SpigotMC - High Performance Minecraft This little tutorial is about a very basic obfuscation which just renames classes and methods. We have then to manually indicate this to ProGuard using-keepconfiguration rules to preserve such items (see also ProGuard configuration made easy). -keeppublicclassproguard.ProGuard{ Since no such class is used in the application, this warning can be ignored.
