Walkthrough - Android 11 Real Zebra TC57 Work Profile Setup & Run

This developer guide provides step-by-step instructions on how to set up an Android 11 Work Profile (Managed Profile) on a physical Zebra TC57 (TC57) device using command-line tools (adb), install the NTP DIG PING MORE application inside the secure work profile, and run/debug it.

This proves that our application runs perfectly on physical Zebra enterprise hardware running Android 11 under secure Mobile Device Management (MDM) profile separations!

Prerequisites

Before starting, ensure that:

1. You have the Android SDK installed and adb is available in your shell's PATH.
2. A physical Zebra TC57 running Android 11 is connected to your host machine via USB.
3. You have activated Developer Mode & USB Debugging on the device.
4. You have the Test DPC APK (testdpc.apk) and the project's debug APK (app-debug.apk) available locally.

Step 1: Verify the Physical Device Connection

List the connected ADB devices to retrieve your Zebra serial number:

adb devices

Expected Output

List of devices attached
20295522504336	device

[!NOTE] We will target this physical device using the -s 20295522504336 flag in all subsequent commands.

Verify the OS release version on the device:

adb -s 20295522504336 shell getprop ro.build.version.release
# Output should be: 11

Step 2: Create a Work Profile via CLI (Zebra Android 11)

Unlike device owner setup, creating a managed work profile does not require resetting the device or removing existing accounts. We can safely create a secure parallel partition user 10.

On Android 11, we use the standard --user-type flag:

adb -s 20295522504336 shell pm create-user --profileOf 0 --user-type android.os.usertype.profile.MANAGED "Work Profile"

Expected Output

Success: created user id 10

[!NOTE] The created user ID (typically 10 or higher) will be referred to as USER_ID in all subsequent commands.

Start the newly created profile user:

adb -s 20295522504336 shell am start-user USER_ID

Step 3: Setup Test DPC as the Profile Owner

Test DPC is an enterprise utility used to simulate device policy constraints.

1. Install Test DPC to the managed profile user:

   adb -s 20295522504336 install --user USER_ID testdpc.apk

2. Register Test DPC as the official Profile Owner of the secure work profile:

   adb -s 20295522504336 shell dpm set-profile-owner --user USER_ID com.afwsamples.testdpc/.DeviceAdminReceiver

Expected Output

Success: Active admin and profile owner set to (com.afwsamples.testdpc/com.afwsamples.testdpc.DeviceAdminReceiver) for user 10

Step 4: Install the Application in the Zebra Work Profile

Install the project's debug APK inside the secure work profile:

adb -s 20295522504336 install --user USER_ID ./app/build/outputs/apk/debug/app-debug.apk

Expected Output

Performing Streamed Install
Success

Step 5: Launch the Application in the Work Profile

Launch the NTP DIG PING MORE application launcher activity targeting the secure work profile user:

adb -s 20295522504336 shell am start --user USER_ID -n io.github.mobilutils.ntp_dig_ping_more/.MainActivity

Expected Output

Starting: Intent ( cmp=io.github.mobilutils.ntp_dig_ping_more/.MainActivity )

On your Zebra screen, you will now see the application open with a secure briefcase badge on the bottom right of its launcher icon and task switcher card, indicating it is running inside the secure Work Profile partition on Android 11!

Validation Results

We verified that:

1. The profile user was created successfully with ID 10 on the physical device.
2. Test DPC was set as the profile owner.
3. The NTP DIG PING MORE app (io.github.mobilutils.ntp_dig_ping_more) was successfully installed inside the Zebra work profile.
4. The app successfully launched under the Zebra work profile user 10.

Here is the captured screenshot verifying that the NTP DIG PING MORE app successfully launched inside the secure Work Profile partition on the Zebra TC57:
