#HiBeaver

HiBeaver is an android plugin for modifying your library jars byte code.

Dress them as if they are naked! Yeah~

This plugin is uploaded to jitpack. You can use this by adding the following code to your buildScripts:

classpath 'com.github.BryanSharp:hibeaver:1.2.1'

jitpack Maven Repo is needed, add this:

maven { url 'https://jitpack.io' }

and then add this to you app build scripts:

apply plugin: 'hiBeaver'
import com.bryansharp.gradle.hibeaver.utils.MethodLogAdapter
import org.objectweb.asm.ClassVisitor
import org.objectweb.asm.MethodVisitor
import org.objectweb.asm.Opcodes
//or you can import like bellow:
//import org.objectweb.asm.*
hiBeaver {
    //this will determine the name of this hibeaver transform, no practical use.
    hiBeaverModifyName = 'myHibeaverTest'
    //turn this on to make it print help content, default value is true
    showHelp = true
    //this flag will decide whether the log of the modifying process be printed or not, default value is false
    keepQuiet = false
    //this is a kit feature of the plugin, set it true to see the time consume of this build
    watchTimeConsume = false

    //this is the most important part

            ],
    ]
}

You can also see the content above in the build log outputs.

There is also a demo showing how to use it. You can either get it through git submodule and add a settings.gradle file to include the module, or get it by checking out hiBeaverDemo.

Hope you can enjoy it! Any comment and suggestion is welcomed.
