Oreo is coming! Are you ready?

Oreo is coming! Are you ready?

The JetAdvantage Link platform development team has been working hard over many months to update the core of our device platform to conform to API version 26 (commonly known as Oreo, or 8.0).

Having concluded internal testing and a limited-release beta (Beta1), we are now ready to share our work with the entire app developer community for your evaluation and feedback (Beta2) and most importantly to give you time to adapt your apps if necessary prior to its official release.

Here are some tips for making sure your apps are “Oreo ready”:

Download the Oreo Beta2 firmware from the Download page now and take it for a test drive with your app. Please follow these steps:

  1. Uninstall all apps and remove the printer from HP Command Center (if the printer had been previously added)
  2. Perform a format disk operation
  3. Install the Oreo Beta2 firmware from a USB thumb drive
  4. Configure the printer’s web proxy (if necessary)
  5. Register the printer with HP Web Services (if necessary)
  6. Enable LDB mode
  7. Install your app using the HPKTool
  8. Push your app’s App Attestation debug credentials using the HPKTool (if necessary)
  9. Run your app, noting all anomalies encountered

For any anomalies found, first check your usage of the APIs. In our testing so far, most of the anomalies were actually due to the app’s incorrect use of the APIs or reliance on deprecated APIs.

If a defect in the Link Platform is proven or even strongly suspected, please report it through the Link for Device SDK support forum. Indicate in your post that you are using the Oreo Beta2 firmware image.

When your Oreo Beta2 testing has concluded and any app adjustments have been made, please:

  1. Perform a format disk operation
  2. Install the latest Public Release Firmware Image from a USB thumb drive
  3. Configure the printer’s web proxy (if necessary)
  4. Register the printer with HP Web Services (if necessary)
  5. Delete any copies of the Oreo Beta2 firmware you may have downloaded

Thank you in advance for participating in the Oreo Beta2.
