Installing using QR code

On devices that don’t support NFC, the TDM install can be initiated using a QR code. These instructions are for devices with Internet access. Alternative instructions are available for devices without internet and devices without NFC or cameras.

Generate a QR code for Internet-hosted application

You need to generate a QR code with the Android provisioning information. Copy and edit the configuration below using a text editor:

{
  "android.app.extra.PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME":
      "com.xewli.tdm/.DeviceAdminReceiver",
  "android.app.extra.PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION":
      "https://storage.googleapis.com/xewli-tdm/xewli-tdm.apk",
  "android.app.extra.PROVISIONING_DEVICE_ADMIN_SIGNATURE_CHECKSUM":
      "Zf2Gj2O_5azDWIBTiycIqtIjgLmUGWqo6afFygDnfzU",
  "android.app.extra.PROVISIONING_SKIP_ENCRYPTION": false,
  "android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED": false
}

Generate a QR code for the configuration: there are tools available online that generate the QR code as an image that can be downloaded and re-used later.

Install


  1. At the first Android Setup Wizard screen, tap the screen until the camera appears for reading the QR code.

  2. Move the device so that the front camera is pointing at the QR code. The QR code will be read automatically once it is in focus. You can move the device closer or further away from the QR code to help the camera focus.

  3. Select your Wi-Fi access point and provide the passphrase.

  4. Complete the Android Setup Wizard steps.

  5. On the Tactical Device Manager splash screen, press Get started.

  6. On the Terms & conditions screen, check the checkbox to accept the T&Cs then press Continue.

  7. At the Hold the SmartLicence… screen, hold the smartcard to the rear of the phone until the next screen appears.

  8. If you want to install applications:

    1. At the Install applications screen, select Install apps from USB now.

    2. Attach the USB media device and press Continue.

    3. When the OS asks to allow TDM access to the memory device, press OK.

  9. At the Initial policy screen, remove the USB media device and then select an initial policy and press Continue.

  10. At the Administrator authentication screen, enter either an 8-digit PIN or a passphrase. This is used to lock TDM and prevent unauthorised changes to your device policy. This is used only by administrators.

  11. At the User authentication screen, provide a PIN or passphrase for the device’s lockscreen. This will be used by the end user. Its length is determined by the initial policy.

  12. At the Setup complete screen, press Finish.
