统计new出来的对象数量，路径

reference-plugin

tip:jCenter 传不了了，需要测试本地直接引用~~

demo.apk

dump new出来的对象个数，大小
内存占用大小目前使用jvm ti，android9及以上才支持，还是耗时的，可以先dump数量，再考虑是否需要dump 内存大小

日志
START--------------------------------------------------
-
//StringBuilder存在14个
CLASS - java.lang.StringBuilder count: 14
// 耗4624字节，由App$onCreate$1#timer产生11个对象
----> size(byte): 4624 count: 11  
com.yan.referencecounttest.App$onCreate$1#timer(LBurialTimer;LString;LString;LString;J)V
//耗1064字节，由App$onCreate$1#<clinit>()V 产生3个对象
----> size(byte): 1064 count: 3  com.yan.referencecounttest.App$onCreate$1#<clinit>()V 
// 总共占5688字节
----> size(byte): 5688 *
END--------------------------------------------------

how to use

in project mode

    classpath 'com.yan.referencecount:reference_plugin:1.1.5'

in app module

apply plugin: 'reference-plugin'

referenceExt {
    logEnable = true
    // 插件工作环境 DEBUG, RELEASE, ALWAYS, NEVER
    runVariant = 'DEBUG'
    // 有些第三次jar包混淆后由些特殊符号,可能会插桩失败,
    // 在EXTERNAL_LIBRARIES域下，只在librariesOnly匹配上的进行插桩
    librariesOnly = ['androidx.']
    // 只插桩到当前匹配的所有类 如果不为空，ignoreList失效 ，内部采用 contains(item)，来包涵匹配到的类
    foreList = ['com.burial.test.TestView']
    // 插桩忽略名单，不需要全类名，内部采用 contains(item)，来剔除配到的类
    // ignoreList = ['com.burial.test.MainActivity2']
    // 作用域 PROJECT,SUB_PROJECTS,EXTERNAL_LIBRARIES,TESTED_CODE,PROVIDED_ONLY
    // EXTERNAL_LIBRARIES lib范围，可能插桩失败
    scopes = ['PROJECT','SUB_PROJECTS']
}

in code

    // 主动调用dump方法，打印日志
    ReferenceMgr.dump();

    // 自定义dump回调，默认打印在logcat
    ReferenceMgr.setOnDumpListener(new OnDumpListener() {
            @Override
            public void onDump(@NotNull HashMap<Class<?>, ArrayList<ReferenceWeak<Object>>> hashMap) {
            }
        });
