android tmp目录权限不够,android - 使用root用户安装APK，处理“ / data / local / tmp /”文件夹的新限制 - 堆栈内存溢出...

背景

到目前为止，我可以通过以下代码使用root(在应用程序内)安装APK文件：

pm install -t -f fullPathToApkFile

并且如果我想(尝试)安装到sd-card：

pm install -t -s fullPathToApkFile

问题

最近，不确定从哪个Android版本开始(至少在Android P beta中存在该问题)，上述方法失败，向我显示此消息：

avc: denied { read } for scontext=u:r:system_server:s0 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0

System server has no access to read file context u:object_r:sdcardfs:s0 (from path /storage/emulated/0/Download/FDroid.apk, context u:r:system_server:s0)

Consider using a file under /data/local/tmp/
