Let's take a look at the tasks that Chris (the IoT team administrator) and Alex (the device owner) have to do, from downloading WSO2 EMM to registering the Android device. WSO2 IoT Server is bundled with the WSO2 Enterprise Mobility Management (WSO2 EMM) capabilities.

Before you begin

  1. WSO2 IoT Server supports devices on Android version 4.2.x to 7.0 (Android Jelly Beans to Nougat).
  2. Install Oracle Java SE Development Kit (JDK) version 1.8.* and set the JAVA_HOME environment variable. For more information on setting up JAVA_HOME on your OS, see Installing the Product.

  3. Download WSO2 EMM and unzip the file. WSO2 EMM is bundled inside WSO2 IoT Server. Therefore, what you will be downloading is the WSO2 IoT Server pack.

    The downloaded pack is referred to as <IOTS_HOME> throughout this document.

  4. Start WSO2 IoT Server's core profile, which corresponds to device management, device plugins, transports, APIs, and authentication and authorization components of WSO2 IoT Server.

    cd <IOTS_HOME>/bin
./iot-server.sh --> for Linux/MAC/Solaris
iot-server.bat --> for Windows

  5. Access the WSO2 device management console by navigating to https://<EMM_HOST>:9443/devicemgt. Use admin as the username and the password. You will see the Admin role and the Admin user.

    Have you run the sample script previously when trying out the iOS quick start guide? If so, delete the two users Alex and Chris, the role iotMobileUser, and the sample policies that were created for Android, iOS, and Windows.

Let's get started!

Creating users and a sample policy

Follow the steps given below to create the two users Alex and Chris, and a configured passcode policy. This is done so that it will be easy for you to try out the quick start guide.

  1. Navigate to the <IOTS_HOME>/samples/mobile-qsg directory and start the mobile-qsg script.

    cd <IOTS_HOME>/samples/mobile-qsg
./mobile-qsg.sh --> for Linux/MAC/Solaris 
java -jar mobile-qsg.jar --> for Windows

    When you add a new user to WSO2 IoT Server, the user receives an email with the username and password that needs to be used to log in to WSO2 IoT Server. In this quick start guide, we have not configured WSO2 IoT Server to send emails. Therefore you will get an error in the terminal where the core profile is running. If you don't want to see this error, you need to configure the email settings. For more information, see the WSO2 IoT Server documentation on Configuring the Email Settings.

Check out the WSO2 EMM dashboard by signing in to the WSO2 IoT Server console using chris as the username and chrisadmin as the password: https://<EMM_HOST>:9443/devicemgt.  
You will then see the new iotMobileUser role, 3 new policies (only 2 policies will be created if you have not configured WSO2 IoT Server for iOS), and 2 new users that were added using these scripts.

Registering the Android device

WSO2 IoT Server supports devices on Android version 4.2.x to 7.0 (Android Jelly Beans to Nougat).

Android restricts third-party apps and less secure apps from being installed on the device. Therefore, you need to configure your device to disable this restriction as the WSO2 EMM device management agent application acts as a third-party application.

 Click here for more information on how to enable third party application installations.

 Follow the steps given below:

  1. Navigate to Setting > Security.
  2. Enable the Unknown sources option.

The role Chris assigned to Alex, has permission to enroll a device. Therefore, Alex follows the steps given below to enroll the Android device:

  1. Sign in to the WSO2 EMM device management console using alex as the username and alexuser as the password.

  2. Click Enroll New Device.
  3. Click Android to enroll your device with WSO2 EMM.

  4. Scan the QR code to download the Android agent onto your Android device.

    Make sure that your Android device and the WSO2 EMM are on the same network, else you will not be able to download the Android agent.

    After scanning the QR code you will be directed to a web page. When this page appears, the web browser will typically display an "insecure connection" message, which requires your confirmation before you can continue.

     Click here for more information.

    The WSO2 EMM consoles are based on the HTTPS protocol, which is a combination of HTTP and SSL protocols. This protocol is generally used to encrypt the traffic from the client to server for security reasons. The certificate it works with is used for encryption only, and does not prove the server identity, so when you try to access these consoles, a warning of untrusted connection is usually displayed. To continue working with this certificate, some steps should be taken to "accept" the certificate before access to the site is permitted. If you are using the Mozilla Firefox browser, this usually occurs only on the first access to the server, after which the certificate is stored in the browser database and marked as trusted. However, with other browsers, the insecure connection warning might be displayed every time you access the server.

    This scenario is suitable for testing purposes, or for running the program on the company's internal networks. If you want to make these consoles available to external users, your organization should obtain a certificate signed by a well-known certificate authority, which verifies that the server actually has the name it is accessed by and that this server belongs to the given organization.

  5. Alex taps Download IoT Server Agent on this screen.

    Open the downloaded file.

  6. Tap INSTALL to start installing the Android agent.
  7. Tap OPEN, once the WSO2 Agent is successfully installed.

  8. Tap SKIP AND GO TO ENROLLMENT, which will direct you to install the device with WSO2 IoT Server in the default manner.

    Tip by Chris

    In WSO2 EMM, data containerization is implemented using the Managed Profile feature. For more information on how to set up the Work-Profile, see Setting Up the Work Profile. You need to tap on the given options only if your device is on the Lollipop OS version or above. Else, move to the next step.

  9. Enter the server IP and the port as your server address in the text box provided and tap START REGISTRATION.

    Example: Register the device via HTTP: 10.100.7.35:8280

  10. Enter your details and tap SIGN IN. A confirmation message will appear..
    • Organization - In this example, Alex leaves the Organization empty, as it is only required if the server is hosted with multi-tenant support. 
    • Username - Enter alex as the username.
    • Password - Enter alexuser as the password.
  11. Read the policy agreement, and tap Agree to accept the agreement. 

  12. Tap ACTIVATE to enable the WSO2 EMM device administrator on your device. A confirmation message appears after enabling the device admin.

  13. Tap ALLOW to allow the WSO2 Android agent to make and manage phone calls, and to access photos, media, files, and the device location.

    You will get this message only if your device is on Android OS Marshmallow (6.0) or above.

    Example:

  14. Alex sets a PIN code with a minimum of four digits and taps SET PIN CODE. The PIN code is used to secure your personal data. Therefore, WSO2 EMM will not be able to carry out critical operations on your personal data without using this PIN. 
    Example: If Chris needs to enterprise-wipe Alex's device or remove data from the device, Chris cannot directly wipe it without the PIN code. 

    You will be prompted to provide a PIN code only if your device is a BYOD device.

  15. You have now successfully registered your Android device. Tap Device Information to get device specific information, and tap Unregister if you wish to unregister your device from WSO2 EMM.

Updating the passcode policy

As a security measure, the MobX management has requested Chris to update the passcode policy for all Android devices so that a device user can only enter the wrong password four times. If a user fails to enter the correct password in the fourth attempt, the device will not be accessible for 15 minutes. This can be regulated in WSO2 EMM by updating the passcode policy that was already in place. Chris follows the steps given below to update the policy:

  1. Access the WSO2 EMM console by navigating to https://<EMM_HOST>:9443/devicemgt .

    Tip by Chris

    1. By default, <IOTS_PORT> has been set to 9443 for HTTPS and 9763 for HTTP. Since we access the IoT console over HTTPS, use 9443 in the URL.

    2. When the pages appear, the web browser will typically display an "insecure connection" message, which requires your confirmation before you can continue.

       Click here for more information.

    1. Sign out from Alex. Enter chris as the username and chrisadmin as the password.

    2. Click LOG IN. 

    The device management dashboard appears, giving you easy access to the devices, users, and policies in your organization. 

  2. Click View under POLICIES.
  3. Click the  icon that is on the passcode policy for Android devices.

  4. Update the passcode profile that is already in place by defining the maximum fail attempts as 4, and click CONTINUE.

    1. A profile in the context of WSO2 EMM refers to a collection of policies.
    2. If you want to know more about each policy setting, hover your mouse pointer over the help tip.
      Example:

  5. Update the user group details as below.

    1. Chris selects the set user role/s option and then selects the iotMobileUser role from the item list.

    2. Click CONTINUE.

  6. Optionally, you can update the name and the description of the policy.

  7. Click SAVE & PUBLISH to make the policy active immediately when the device enrolls with WSO2 EMM.

  8. Click SAVE to save the configured profile or click SAVE & PUBLISH to save and publish the configured profile as an active policy to the database. It is mandatory that the policy is assigned to Alex's mobile device, so Chris clicks SAVE & PUBLISH to make the policy active immediately when the device enrolls with WSO2 EMM.

    • If you SAVE the configured profile, it will be in the inactive state and will not be applied to any devices.
    • If you SAVE & PUBLISH the configured profile of policies, it will be in the active state. The active policies will be enforced on new devices that enroll with WSO2 EMM based on the policy enforcement criteria.
    • If you want to push this policy to the existing devices and want this policy to be applied to the devices, click APPLY CHANGES TO DEVICES.

Once the policy is pushed to the device, Alex gets a notification to update the device's passcode/password so that it meets the requirements configured in the policy. 

Publishing Applications

Chris needs to publish the WSO2Con-Android application that was created when running the mobile-qsg script.

  1. Navigate to the App Publisher using the following URL: https://<EMM_HOST>:9443/publisher. Use chris as the username and chrisadmin as the password.

  2. Click Submit for Review for the WSO2Con-Android application.

  3. Click Approve and then click Publish. The App Catalog application is now published. 

The WSO2Con-Android application is now available in the app store for device owners like Alex to install on their device.

To know more about the mobile application lifecycle, see the WSO2 IoT Server documentation on Mobile Application Lifecycle Management.

Trying out Android device operations

Alex can now navigate to the Device Management page, view information specific to the device, and carry out operations on the device as explained below:

  1. Access the WSO2 EMM's device management console using alex as the username and alexuser as the password that was sent via email.
  2. Click View under DEVICES.

  3. Click on the registered device.

    Alex tries out the various device operations via the WSO2 EMM console.

    1. Alex misplaces the mobile device, so Alex clicks Ring to ring the device and find out if the device is lying around the workspace.

    2. Alex then remembers that the phone was unlocked, so Alex uses the Device Lock operation to lock the device so that the content in the device will be safe.

    3. Using the Location operations Alex finds out that device is in Chris's office. Alex calls Chris and asks Chris to call back from the device.

    4. To make sure Chris can call using the device, Alex removes the device lock (password) using the Clear Password  operation.

    For more information on the available features, try out the Android operations.

Installing an application on the Android device

MobX wants Chris to ensure that the employees can only download mobile applications made available via the MobX app store. For this, Chris creates and publishes the WSO2Con-Android to the MobX app store.

Before installing the application on the device, make sure that the AppDownloadURLHost property in the <IOTS_HOME>/ conf/app-manager.xml file is configured to http. Else, an error occurs when installing the application in this tutorial.

<Config name="AppDownloadURLHost">%http%</Config>

If you want to install applications using HTTPS, you need to Generating a BKS File for Android. For more information, see the WSO2 IoT Server documentation.

Let's take a look at how Alex installs this application on the device.

  1. Navigate to the App Store using the following URL:  https://<IOTS_HOST>:9443/store 

  2. Sign in using alex and alexuser as the username and password.

  3. Click the WSO2Con-Android mobile application, and click Install. 

    You can install the application on many devices in one go too, which is know and enterprise install. By default, only the administrator can enterprise install applications. For more information on enabling the enterprise subscription for other user roles, see the WSO2 IoT Server documentation on Enabling Enterprise Subscriptions for Mobile Apps.

  4. Select Instant install, and click Yes.
  5. Click on your device in the pop-up menu to install and subscribe to the application.
    A success message will be shown when you have successfully subscribed to the application.
  6. Tap Install on your device to finish installing the application.
    Now you can use start using the application.
