51Degrees Device Detection Java  4.1

Device detection services for 51Degrees Pipeline


This example shows how to use the 51Degrees Cloud service to lookup the details of a device based on a given 'TAC'. More background information on TACs can be found through various online sources such as Wikipedia.

This example is available in full on GitHub.

To run this example, you will need to create a resource key. The resource key is used as shorthand to store the particular set of properties you are interested in as well as any associated license keys that entitle you to increased request limits and/or paid-for properties.

You can create a resource key using the 51Degrees Configurator.

Make sure to include the HardwareVendor, HardwareModel and HardwareName properties as they are used by this example.

Example output:

This example shows the details of devices associated with a given 'Type Allocation Code' or 'TAC'.
More background information on TACs can be found through various online sources such as Wikipedia: https://en.wikipedia.org/wiki/Type_Allocation_Code
Which devices are associated with the TAC '86386802'?
Coolpad 5217 (5217)
Coolpad 5200 (5200)
Coolpad 5310 (5310)
Coolpad 5311 (5311)
Coolpad 5315 (5315)
Coolpad CoolPad Unknown (CoolPad Unknown)
Which devices are associated with the TAC '35925406'?
Apple iPhone 6 (A1586)
