android - 什么是 (D/NSD : curPkgName is not in list)?

Question

当我进入 RegisterActivity 打印 logCat 时，我正在处理新项目

11-07 20:12:09.305 26674-26674/com.rosheta D/NSD: curPkgName is not in list

太多而不停止打印它。
这是什么？这是一个错误吗？打印这么多日志会降低应用程序的性能吗？

这是我的 RegisterActivity

[更新]我找到了一种方法来过滤此日志以防止向我的 logcat 发送垃圾邮件在 logcat 的右上角选择 Edit Filter Configuration
1-in filter name 写你的应用名称
2-在 package name 写你的 app_package_name
3-in (Log message write ^((?!(?:THE_TAG_YOU_NEED_TO_IGNORE)).)$ 或者 Log tag 写 ^((?!(?: THE_TAG_YOU_NEED_TO_IGNORE))).)$)

那么这不是您代码中的错误。华为手机显示此日志，但尚未修复。所以忽略它。
