Hi,

Thanks for great library. Is it possible to use Hugo with retrolambda? I was trying to use them both in one project without any success. Everything is compiling but I don't see any hugo's logs when I start app.

I've changed hugo-example app where you can reproduce it ( https://github.com/radzio/hugo/blob/master/hugo-example/build.gradle )

Any ideas / suggestions?

Cheers, Radek

This commit will fix the VerifyError listed in https://github.com/JakeWharton/hugo/issues/9

The issue seems to have been resolved by upgrading to the latest build tools.

Before using Hugo I used my own util class with such methods (same for methods, that return void):

public static <T> T howLong(String methodName, Method<T> command) {
    try {
      final long startTime = System.currentTimeMillis();
      final T result = command.execute();
      Timber.d("%s executed in %dms, thread: %s", methodName, System.currentTimeMillis() - startTime, Thread.currentThread().getName());
      return result;
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

Im trying to write gif encoder from scratch, and I log almost everything. I noticed, that all execution is pretty long, but one method (that should be the longest) is not long at all, I tried to log every other method, and finally I use my old util to log time and what I got:

V/AmazingGifEncoder: ⇠ map [1065ms] = [0x36, 0x36, 0x36, 0x36, 0x36, 0x36, 0x36, 0x36...
D/TimeUtils: Mapping pixels executed in 6745ms, thread: RxComputationThreadPool-1

At the same moment total execution time seems to be calculated correctly:

V/AmazingGifEncoder: ⇠ addFrame [7213ms]
D/TimeUtils: Adding frame executed in 7215ms, thread: RxComputationThreadPool-1

Project with multi-module setup (application + library) does not log methods annotated with @DebugLog from library module. In application module it works fine.

here is example https://github.com/curilpe/hugo-test

EDIT:

problem is not in hugo but in android gradle plugin because all library modules are release builds regardless of build type of application.

to change it to debug build just put in build file of library module

android { defaultPublishConfig "debug" }

Hi, I am trying to follow your instructions for disabling hugo in Gradle. I put this in my app's build.gradle file: hugo { enabled false }

However, Android Studio is throwing a build error:

Error:(32, 0) Gradle DSL method not found: 'hugo()'

Please advise how I can correct this. Igor

Trying to use your (wonderfull, thank you so much for that) plugin in my app. Wrote this (as per your README.md):

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'
        classpath 'org.robolectric:robolectric-gradle-plugin:0.11.+'
        // The following adds the ability to use @DebugLog on methods
        classpath 'com.jakewharton.hugo:hugo-plugin:1.1.0'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

apply plugin: 'com.android.application'
apply plugin: 'com.jakewharton.hugo'

Got:

Plugin with id 'com.jakewharton.hugo' not found

Changed to

apply plugin: 'hugo'

and it worked perfectly! So either I'm missing a point here (being a complete groovy/gradle beginner, that's quite possible) or you need to update your README

I have noticed that Hugo stopped outputting anything in the logcat. At the same time, I got a bunch of aspectJ error logs in my app root folder. I think it has to do with the inner class you usually create when you need parcelables.

Here is basically what the logs say:

org.aspectj.weaver.BCException: Whilst processing type 'Lcom/wannacorp/api/model/VirtualZone$1;' - cannot cast the outer type to a reference type.  Signature=Lcom/wannacorp/api/model/VirtualZone; toString()=com.wannacorp.api.model.VirtualZone

Not sure if this is in the scope of Hugo, but have an annotation for wrapping methods in Trace.beginSection/endSection would be very helpful.

Maybe a parameter to @DebugLog? @DebugLog(trace=true) Maybe a separate annotation ( @DebugTrace ) ?

output would function like:

class Bar{
  void foo(int snarg){
     if( SDK_INT >= 18 ){
            Trace.beginSection("Bar.foo(snarg="+ snarg+")")); 
      }
      try {
             <method_body>
      } finally {
         if( SDK_INT >= 18 ){
             Trace.endSection();
         }
      }
  }

}

I would like to be able to give @DebugLog a parameter which en-/disables the logging. I don't wan't to see all logs everytime. So eg. if I'm interested in the api logs I would adjust my verbose constant to see them and if I'm interested in other parts I can disable them (to don't be distracted).

My project has a number of modules apart from the actual app. Today I've tried to use Hugo on one of the 'android-library' modules, and nothing is logged when the app module runs.

Project modules: app (has compile project(':mylibrary')) mylibrary (has apply plugin: 'hugo')

Already tried to also apply plugin: 'hugo' on the app module, with no luck.

when Open camera and show unfortunately Stop how to solve it i using this library on our app it work perfect but different device on different times show its type msg how can solve this type of issue

Parallel builds. This project contains multiple modules. Parallel builds can improve the build speed by executing tasks in parallel. We can enable this feature by setting org.gradle.parallel=true.

Configuration on demand. Configuration on demand tells Gradle to configure modules that only are relevant to the requested tasks instead of configuring all of them. We can enable this feature by setting org.gradle.configureondemand=true.

gradle caching. Shared caches can reduce the number of tasks you need to execute by reusing outputs already generated elsewhere. This can significantly decrease build times. We can enable this feature by setting org.gradle.caching=true.

Gradle daemon. The Daemon is a long-lived process that help to avoid the cost of JVM startup for every build. Since Gradle 3.0, Gradle daemon is enabled by default. For an older version, you should enable it by setting org.gradle.daemon=true.

===================== If there are any inappropriate modifications in this PR, please give me a reply and I will change them.

I have a multi-module Android project in Kotlin. When I am trying to use Hugo in that I am getting an error message during build saying that the advice was not applied. Below is the exact message I am getting, can anyone tell me why?

Task :ui:compileDebugJavaWithJavac advice defined in hugo.weaving.internal.Hugo has not been applied [Xlint:adviceDidNotMatch]

I have created a sample project to demonstrate this behavior, you can check it here. https://github.com/suvro/test-android-aop
