Servicemanager uses file-system config to isolate services and the directories they can access so if u want services to write/read to some place at the file-system then this config must be modified or you can add that service or process which it's in to a group.

Checkout android private file-system config.

The low-level user-space cgroup code is in system/core/cutils/ .grep for cgroup there and find the low-level API name.
I recall that the higher-level user-space cgroup that makes the policy decision isin ActivityManager, in frameworks/base. grep for the code that callswhatever API name you found above.

Share app process in Android 5.0 multiple user environment?

In Android5.0, an App(apk) can be installed in multiple users. When the App is running in another user, there is a new process of the App. I want to develop a App which is running in multiple users but only one process is created. Some system process, such like "com.android.phone" is running in this way. But I can not find the way to do that.

I have tried as below, but don't work.

use sharedUserId as system, and mark persistent to be true;
sign app as platform signature, put the apk to /system/app or /system/priv-app/;

However, service/recevier/provider can use in manifest.xml to share the same component although.(single user tag must be installed in /system/priv-app/).
