Error on device-policy(clouddpc): policies.json file not found for dedicated devices using Android Management API

Question

I am using Android-Management API and QR Code scan after factory reset to provision devices as dedicated device. but provisioning process fail because device-policy app is installed but failed to sync policies. I checked with "adb logcat" while trying to manually sync policies using device-policy app. adb logcat shows:

Can anyone please help me to fix this issue?

Answer 1

This usually happens when you create an enrollment token without a policy. If you want to enroll a device without a policy, it is advisable to create a blank policy and assign it during the creation of the enrollment token instead.

policy_name = enterprise_name + '/policies/policy_default'
policy_json = {}

policy = androidmanagement.enterprises().policies().patch(
    name=policy_name,
    body=policy_json
).execute()

enrollment_token = androidmanagement.enterprises().enrollmentTokens().create(
    parent=enterprise_name,
    body={"policyName" : policy_name}
).execute()

If the device enrolled is not linked with a policy within 5 minutes, the enrollment will fail and the device will be factory reset.
