You can pull the policy file and analyze it.您可以拉取策略文件并对其进行分析。
adb pull /sys/fs/selinux/policy
But if you added it to system/sepolicy and built/flashed the images, I don't see how they could not have been applied.但是如果你将它添加到system/sepolicy并构建system/sepolicy图像，我看不出它们是如何被应用的。
If you're still seeing denials even after adding the allow rules, it's either a) There is another denial that appeared after the last allow b) There is also MSL security at hand.如果您在添加允许规则后仍然看到拒绝，则可能是 a) 在最后一个允许之后出现另一个拒绝 b) 还有 MSL 安全性。 See this answer here: https://stackoverflow.com/a/45551191/3801327在此处查看此答案： https : //stackoverflow.com/a/45551191/3801327
