From the beginning I designed in the way that it could evolve into a system with a single core and multiple plugins and extensions. So that people could customise it in the most suitable way. And as a first step into that direction I would like to present you . Pury Plugins Custom Plugins In the previous version it was possible to change a to take advantage of libraries like Timber. allow much more flexible customisation. They provide access to raw results to process them in the most suitable way. For example, it could be interesting to compare performance between master and feature branch, I have a few ideas how to do that, but didn’t tried them yet. Or change formatting to a JSON, run application in a device farm, collect results and compare them with some script. I always wanted to measure application performance on live. So I played a bit with Analytics and got promising results. Instead of getting standard Pury output: Logger Plugins Google App Start --> 0msSplash Screen --> 5msSplash Load Data --> 37msSplash Load Data <-- 1042ms, execution = 1005msSplash Screen <-- 1042ms, execution = 1037msMain Activity Launch --> 1043msonCreate() --> 1077msonCreate() <-- 1100ms, execution = 23msonStart() --> 1101msonStart() <-- 1131ms, execution = 30msMain Activity Launch <-- 1182ms, execution = 139msApp Start <-- 1182ms I sent execution times to and got this: Google Analytics Timing API As you can see I got all execution times in a single table. Taking into account , it could be a very powerful to analyse application performance across different versions and devices. I’m planing to write an article about Google Analytics Timing API and Google Analytics Plugin once it is released, but in the meantime I would like to go back to Pury Plugins in general. GA Segments tool Plugin creation To create a custom plugin you need to implement interface: Plugin public interface Plugin {    void handleResult(ProfileResult result, ProfilerId profilerId);} In receives a result of profiling and an identifier of the profiler which produced the result. It worth to mention that is an interface with 4 different implementations. To simplify result processing I made a use of , each result has a method And this is interface: handleResult() Plugin ProfileResult Visitor Pattern accept(ResultVisitor). ResultVisitor public interface ResultVisitor {void visit(AverageProfileResult averageProfileResult); void visit(RootAverageProfileResult rootAverageProfileResult);  

void visit(RootSingleProfileResult rootSingleProfileResult);  

void visit(SingleProfileResult singleProfileResult); } There is a method for each of the result type, so no checks or casts are required. I hope you will find it useful. While I was writing support for I thought that filtering input by profiler name could be a very common use case. So if you think that an abstract class that implements and does filtering is useful, please raise an issue . Plugins, Plugin on GitHub How to use Plugins To add and remove plugins on the fly use the following methods: public final class Pury { .... 

public static void addPlugin(String key, Plugin plugin) {}  
public static void removePlugin(String key) {}

.... } There is a behind those two methods, so if two plugins with the same key are added, the first one is removed. Map Logging Plugin With introduction of , I decided to change the way logging works. So now logging is just an another nothing more. To take a look into the code, please, check class. Plugins Plugin, LoggerPlugin is added by default, so logging is working out of the box. To remove or replace it, use the key uses the same as was used for logging results before. To change it use method. LoggerPlugin Pury.LOGGER_PLUGIN. LoggerPlugin Logger, Pury.setLogger(Logger) Conclusion enable customisation and better control over reporting profiling results. They adds a certain degree of flexibility to Pury that, I hope, will be useful. You can find code with example . Plugins on GitHub As I’ve already mention, right now I’m working on integration Pury with Google Analytics. If you are interested in results then follow me on Twitter or here, on Medium. If you have ideas about what else can be done with profiling results, please write in comments or . in Gitter
