ANDR-PERF tryGetService失败; SELinux的

Question

每次我在设备上启动我的应用程序时，我都会在日志中看到此错误。

E / ANDR-PERF：IPerf :: tryGetService失败了！ E / SELinux：avc：拒绝{find} for interface = vendor.qti.hardware.perf :: IPerf pid = 3328 scontext = u：r：untrusted_app：s0：c123，c256，c512，c768 tcontext = u：object_r：hal_perf_hwservice ：s0 tclass = hwservice_manager permissive = 0

我有点困惑这意味着什么。也许我的一个图书馆造成了这个？

此日志文件表示您的某个库具有访问权限（可能是interface = vendor.qti.hardware.perf :: IPerf）违规。您必须重新启动应用并找到有问题的应用。你也可以找到帮助

adb shell ps -eZ | grep  3328 

当您的应用程序同时运行时，从命令行命令有问题的服务。找到受害者（app）后，您必须添加/ external / sepolicy / service_contexts文件SELinux规则以处理访问冲突。
