Android 10 Beta Starts Now! It's time to test your apps.

Android 10 Beta Starts Now!  It's time to test your apps.

In May during our 2020 Virtual Partner Conference we announced some significant improvements to our HP Workpath Platform for Summer and Fall of 2020. One of these key enhancements include implementing Android 10 (also known as Android Q) on our upcoming FutureSmart 25.1 firmware (slated for Oct-Nov release).

Today, we are excited to provide all Workpath app developers access to a Beta version of FutureSmart 25.1 running Android 10. When FutureSmart  25.1 is officially released, we want to ensure quality and app stability for this exciting Workpath platform release. Please complete your testing by July 31 to ensure time to address any issues found.

Moving the HP Workpath Platform to API 29 will require additional testing on your part to check for compatibility with your app. And in some cases, code changes and resubmission for App Center V&V will be required.

Download the Android 10 Beta firmware and release notes 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 Android 10 Beta 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 latest HPKTool
8. Push your app’s App Attestation debug credentials using the latest HPKTool (if necessary)
9. Run your app, noting all anomalies encountered

For any anomalies found, first check the release notes for known issues. Then 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 (For example, using targetSDKVersion < 26).

If an unknown defect in the Workpath Platform is proven or even strongly suspected, please report it through the Workpath SDK support forum. Indicate in your post that you are using the Android 10 Beta firmware image.

Thank you in advance for participating in the Android 10 beta.

HP Workpath SDK 1.4.1 (Rename Preview) Now Available

HP is pleased to announce availability of the HP Workpath SDK version 1.4.1  (Workpath name change preview)

As we announced in December, HP has been working to implement the name change from “HP JetAdvantage Link for Device” to “HP Workpath” throughout our ecosystem. And while not all of this work is complete, we are pleased to announce the availability of the first HP Workpath SDK package with the new naming implemented throughout, including the APIs (namespaces, types, methods, etc.) -- HP Workpath SDK v1.4.1.

This new Workpath SDK v1.4.1 is functionally equivalent to the JetAdvantage Link or Device SDK v1.4.0 in every way – only the names have changed. It is also backward compatible with existing device firmware. But due to the API name changes, you will need to make the corresponding name changes in your app code in order to use it.

All future SDK releases will use the new Workpath naming convention, so you will need to make this change to your app eventually. So why wait? By downloading the new Workpath SDK 1.4.1 and rebuilding your app now, you will avoid this additional step when you upgrade to an even newer SDK to access additional features in the future.

The HP Workpath SDK v1.4.1 is available on the Downloads page.

Remote App Configuration Now Available for All HP Workpath Apps

HP is pleased to announce that Remote App Configuration is now available for all HP Workpath apps.

HP has been working hard to enhance app deployment through HP Command Center (HPCC). A few months ago, we introduced the ability to create and deploy app configurations remotely from within HPCC for several HP developed apps. We have used the intervening time to test and improve that feature under production conditions.

HP is pleased to announce that we are now making Remote App Configuration available for all HP Workpath apps. With a little work on your part, HPCC users will be able to create a unique configuration for a customer and deploy it to your app installed on that customers’ devices -- all through HPCC.

For details, please visit the new Remote Configuration page on the developer portal.

Oreo is here! FutureSmart firmware and Link for Device SDK 1.4 Now Available

HP is pleased to announce the release of Oreo and version 1.4 of the Link for Device SDK.

In June of last year at the 2019 HP JetAdvantage Partner Conference, HP announced our intention to upgrade the HP JetAdvantage Link for Device platform to API version 26 (a.k.a. Oreo) within a year. We are happy to announce that the implementation is now complete, and is included in the latest FutureSmart Bundle (4.10). Thank you to those of you who participated in the Oreo Beta program, helping us ensure the quality of the platform.

To enable all the new features in API version 26, we are also pleased to announce the release of the JetAdvantage Link for Device SDK version 1.4 (associated with the release of FutureSmart Bundle 4.10 device firmware).

Link for Device SDK and Simulator (version 1.4):

Please note: A device firmware upgrade to FutureSmart Bundle 4.10 is required to use this SDK. The firmware will be available on hp.com soon. In the meantime, the firmware has been made temporarily available for download from the SDK Download page.

Download the new SDK and Simulator from the Download page.

Major new features of this version include:

  • Android API Version 26 (Oreo)

Other notable changes in this release include:

  • HPKTool Change

It is now possible to package a Home Screen (Kiosk) App that also uses Accessories

Restrictions:

  • [MASSSTORAGE] Size of getFreeSpace() and getTotalSpace() is not correct.

 

Tips for making sure your apps are “Oreo ready”:

For any anomalies found in your app, first check your usage of the APIs. Most of the anomalies found during Beta were actually due to the app’s incorrect use of the APIs or reliance on deprecated APIs.

Link for Device SDK and Simulator Version 1.3.1 Now Available

Link for Device SDK and Simulator Version 1.3.1 Now Available

HP has identified potential security vulnerabilities with the Link for Device Platform. The potential vulnerabilities could be used to perform remote information disclosure while scanning and printing in some modes (ScanToMe, PrintFromStorage).

To help address this issue, HP is providing an SDK hotfix (1.3.1) and a firmware update (FutureSmart 4.9.0.1). In this new implementation, scan and print data is more securely transferred to and from the app’s own sandboxed data directory. READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions, which are sometimes exploitable through this vulnerability, are no longer necessary.

Note: Existing apps will continue to function on the updated firmware without changes, but will remain susceptible to this security vulnerability.

In order to help mitigate this vulnerability, please update to SDK version 1.3.1 and rebuild and republish your app, specifying a minimum Platform Version of 19.4, at your earliest convenience. Your customers will need to upgrade firmware to FutureSmart 4.9.0.1 or later. In addition, unless your app requires them for some other purpose, please remove READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions.

Download the SDK and Simulator from the Download page now.

Note: FutureSmart bundle 4.9.0.1 will soon be available on hp.com. In the meantime you can download it from the Download page.

Sincerely,

The HP JetAdvantage Link team
