Create multiple profiles for ISLAND app

create_multiple_profiles.md

Setup multiple island spaces

Note: Must have an work profile already setup, So that we can modify fw.sys.max_profiles to allow more work profiles

su # to gain root access
resetprop ro.debuggable 1 
am restart

Modify fw.sys.max_profiles prop

setprop fw.sys.max_profiles 10

Create new work profile

# this is the user id of the initial island which was setup from the application
exid="10"
id="$(pm create-user --profileOf 0 --managed Island | grep -Eo '[0-9]+')"
echo "ID: ${id}"

Open /data/system/users/11.xml and add following code below <name> Island </name> but above <user>

where 11 is the user id of newly created work profile

<restrictions no_wallpaper="true" />
<device_policy_local_restrictions>
    <restrictions_user user_id="10">
        <restrictions allow_parent_profile_app_linking="true" />
    </restrictions_user>
</device_policy_local_restrictions>

It should look like this

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<user id="10" serialNumber="28" flags="4144" type="android.os.usertype.profile.MANAGED" created="1652171823625" lastLoggedIn="1652351262370" lastLoggedInFingerprint="Sat Apr 23 21:25:20 IST 2022" profileGroupId="0" profileBadge="0">
    <name> Island </name>
    <restrictions no_wallpaper="true" />
    <device_policy_local_restrictions>
        <restrictions_user user_id="10">
            <restrictions allow_parent_profile_app_linking="true" />
        </restrictions_user>
    </device_policy_local_restrictions>
    <lastRequestQuietModeEnabledCall>1652340558380</lastRequestQuietModeEnabledCall>
</user>

Execute these commands

cd "/data/system/users/${exid:?}" || exit 1
cp app_idle_stats.xml appwidgets.xml \
   device_policies.xml \
   package-restrictions.xml profile_owner.xml \
   settings_secure.xml settings_ssaid.xml settings_system.xml \
   "/data/system/users/${id:?}/"

Would it be possible to post a screenshot of what the phone and also the island app looks like with this? will I have multiple work tabs and would I be able to clone apps more than once?!

Hey, my /data/system/users/11.xml looks like this :

How can I proceed?
[And can I contact with you anyhow?]

Sorry but i no longer have a rooted device to check if it still works, so can't provide a screenshot.

Yes, multiple tabs show, and yes you can clone one app more than once.

Hmm, seems like a different file type.

Does the device have to be rooted for it to work?

Yes.

Use MT manager to open the xml file to read/edit xml files. Other text editor won't be able to render it correctly.

do you think it could work using termux and shizuku for root permissions (for unrooted devices)?

No. This requires editing the files of the operating system itself in /data/system. Shizuku does not provide true root access, it provides apps with capabilities of unrooted ADB, which cannot access system folders.

Hello friend, how are you? When I ran the command to create the new user work profile with the command below, I got the error below. Can you help me? I can pay for your support friend:
