Hunter

Hunter is a framework to develop android gradle plugin based on ASM and Gradle Transform API. It provides a set of useful, scalable plugins for android developers. You can use Hunter to develop more plugins to monitor your app, enhance 3rd-dependency, enhance android framework.

Plugins based on Hunter support incremental and concurrent compile, so you don't need to afraid of extra build time.

• Timing-Plugin: you can time all your ui-thread methods, and dump the block traces
• OkHttp-Plugin: you can set a global Interceptor / Eventlistener for all your OkhttpClients(Okhttp does not provide interface to set a global Interceptor/EventListener)
• LogLine-Plugin: you can add a line number into every lines of your logcat
• Debug-Plugin: you can simply add a annotation to a certain method, and the method will print all parameters and costed time, return value(JakeWharton's hugo achieves it with AspectJ, I achieve it with ASM)
• More developing plugins can be found in TODO, MeanWhile, your idea is welcome

Timing-Plugin

dependencies {
    implementation 'com.quinn.hunter:hunter-timing-library:0.8.5'
}

repositories {
    maven { url 'https://dl.bintray.com/leaking/maven' }
}

buildscript {
    repositories {
        maven { url 'https://dl.bintray.com/leaking/maven' }
    }
    dependencies {
        classpath 'com.quinn.hunter:hunter-timing-plugin:0.8.5'
    }
}

apply plugin: 'hunter-timing'
    

The Hunter-Timing has a internal default BlockHandler to process the block messages, you can set your custom BlockHandler.

IBlockHandler customBlockManager = new RankingBlockHandler();
BlockManager.installBlockManager(customBlockManager);

You can dump the block trace

customBlockManager.dump()

In addition, hunter-timing-plugin provides a extendsion

timingHunterExt {
    runVariant = 'DEBUG'
    whitelist = ['com.quinn.hunter.timing.DataSource', 'com.foo.package2']
    blacklist = ['com.quinn.hunter.timing.black', 'com.foo.package2']
}

runVariant, its default value is ALWAYS, it means this plugin will perform in both debug build and release build. There are four available runVariant, DEBUG, RELEASE, ALWAYS, NEVER.

whitelist, it means the plugin will only handle the classes in these packages, you can provide package with prefix name.

blacklist, it means the plugin will handle all classes except the classes in these packages, you can provide package with prefix name.

You'd better just provide whitelist or blacklist, if you provide both of them, blacklist is ignored.

OkHttp-Plugin

Maybe your project have serveral OkhttpClients，you need to add your custom Interceptor/EventListener/Dns to every OkhttpClients one by one. But some OkhttpClients come from 3rd library, and you can't add your custom Interceptor/EventListener/Dns to them. I have filed a issue about this problem to Okhttp team.

OkHttp-Plugin can help you to achieve it, you can set a global Interceptor/EventListener/Dns to your all OkhttpClients.

dependencies {
    implementation 'com.quinn.hunter:hunter-okhttp-library:0.8.5'
}

repositories {
    maven { url 'https://dl.bintray.com/leaking/maven' }

}

buildscript {
    repositories {
        maven { url 'https://dl.bintray.com/leaking/maven' }
    }
    dependencies {
        classpath 'com.quinn.hunter:hunter-okhttp-plugin:0.8.5'
    }
}

apply plugin: 'hunter-okhttp'
    

OkHttpHooker.installEventListenerFactory(CustomGlobalEventListener.FACTORY);
OkHttpHooker.installDns(new CustomGlobalDns());
OkHttpHooker.installInterceptor(new CustomGlobalInterceptor());
        

Debug-Plugin

It's a plugin similar to hugo but it's developed with ASM instead of AspectJ. Amd it has a quicker compile speed.

Simply add @HunterDebug to your methods will print all parameters and costed time, return value.

dependencies {
    implementation 'com.quinn.hunter:hunter-debug-library:0.8.5'
}

repositories {
    maven { url 'https://dl.bintray.com/leaking/maven' }
}

buildscript {
    repositories {
        maven { url 'https://dl.bintray.com/leaking/maven' }
    }
    dependencies {
        classpath 'com.quinn.hunter:hunter-debug-plugin:0.8.5'
    }
}

apply plugin: 'hunter-debug'

Logging works in both debug and release build mode, but you can specify certain mode or disable it.

debugHunterExt {
    runVariant = 'DEBUG'  //'DEBUG', 'RELEASE', 'ALWAYS', 'NEVER', The 'ALWAYS' is default value
}

LogLine-Plugin

This is a interesting tool/plugin, sometimes you may need line number to help you locate the logcat content, especially, same logcat print in different lines in the same one java class.

This plugin can help you.

dependencies {
    implementation 'com.quinn.hunter:hunter-linelog-library:0.8.5'
}

repositories {
    maven { url 'https://dl.bintray.com/leaking/maven' }
}

buildscript {
    repositories {
        maven { url 'https://dl.bintray.com/leaking/maven' }
    }
    dependencies {
        classpath 'com.quinn.hunter:hunter-linelog-plugin:0.8.6'
    }
}

apply plugin: 'hunter-linelog'
    

You logcat will be inserted line number automatically.

Origin logcat

I/MainActivity: onCreate

Tranformed logcat

I/MainActivity[21]: onCreate
