Native内存泄漏检测，Android 10以上版本LeakRecordMap size为0 #282

Open gogi2010 opened 1 month ago

用Demo最新版本2.2.2测试多款机型，荣耀、小米、华为，发现仅Andorid 10返回的LeakRecordMap size不为0，Andorid 11-14 LeakRecordMap size都是0，是不是还不支持，还是配置有问题？

以下是Android 10测试的日志，发现libmemunreachable打印的对象未减少的情况下，LeakRecordMap size开始大幅度减少，是不是检测机制也有问题啊？如下日志，当libmemunreachable有342对象时，LeakRecordMap size为331，当libmemunreachable有336对象时，LeakRecordMap size变成14了，掉的太快了

你好，能否先给个Android 11-14是否支持Native泄漏检测的结论呀，我们有个问题排查需要用的这个Native泄漏检测功能，很着急
