18M Capsule SDK Release Notes

No Loading Release Submissions

Starting with 18M, you can no longer load release submissions in Bixby Developer Studio (Bixby Studio). Overall, we think this is a healthy change, though this might require you to adjust your workflow.

If you leave the CAN revision override empty on a non-Bixby Studio client (such as a mobile device), you will access the CAN release submission currently deployed to the environment.

Initially, we will only deploy CAN release submissions from the Bixby 2.0 release-manifest. A new end-user environment will be available soon that will allow you to test your capsule on a real device (such as mobile). It will also allow favoriting so that users have personalized CANs, each trained with different subsets of capsules.

You can continue to load private and public submissions. To test your capsules, please create private submissions (containing a single capsule) and load those submissions in the Simulator or non-Bixby Studio clients. It should be fast and reliable.

Note

If you have previously loaded a release submission in the Simulator, you will need to clear it. Otherwise, you will receive errors.

"result-view" Can Trigger "halt" effects

VIV-19381

With this release, you can once again trigger a result-view with a halt effect.

New Storage Prompts Localization

VIV-18770

You now have the ability to localize storage prompts, which are generated when Bixby asks for permission to store a preference in the user's profile.

Example:

profile-support {
match: FlightPreferences
storage-prompt {
confirmation-type (PreferenceConfirmation)
message (Store your flight preferences?)
confirm-label (Yes)
deny-label (No)
}
}

Learn more about localizing storage prompts in the Developer Guide.

New Support for SPS Payments using HTTP POST

VIV-17304

You can now use the HTTP Post request method to deliver SPS payments using http.spsProxyPost.

Read more about Supporting Payments in the Developer Guide.

18L Capsule SDK Release Notes

Support for Readable Names for Client Apps

VIV-18106

Both client-app-support and the requires key within app-launch now support the app-name sub-key. This sub-key allows you to specify a human-readable name for display purposes. This is in addition to the package name specified in app-id.

client-app-support {
app-id (samsung.ugly.package.id)
app-name(Nice App Name)
app-min-version (123)
app-store-url(...)
}
app-launch {
payload-mapper (...)

requires {
app-id (samsung.ugly.package.id)
app-name(Nice App Name)
app-min-version (123)
app-store-url(...)
}
}

Support for Non-Sensitive Info in SPS Payments

VIV-18821

If you are using SPS payments, you can now add a new $paymentCard input to access non-sensitive information about the card confirmed by the user.

The $paymentCard object looks like this:

{
last4: "9999",
address1: "1445 Norwood Ave",
address2: "Building 5",
city: "Itasca",
state: "IL",
zip: "60143",
country: "US",
phone: "18885551212"
}

For more information, learn about Passing a User's Non-Sensitive Card Information in the Developer Guide.

Conversation Drivers for Confirmations

VIV-18608

We've added confirmation-drivers to the confirmed-by key.

Learn more about Conversation Drivers in the Developer Guide.

18K Capsule SDK Release Notes

Updated: June 11, 2018

Changes to "result-view"

VIV-17842

If you implement a result-view block within your capsule, you should ensure that you properly guard against empty results. Because an available result-view is now also used in the absence of results, you might have else blocks triggering unintentionally. For example, in a hotel booking capsule, the following conversation-driver is insufficient because it doesn't guard against a case where there are no results.

Incorrect:

  conversation-drivers {
    if (size(this) > 1) {
      conversation-driver (Free parking)
      conversation-driver (Pool)
      conversation-driver (3 Stars)
    } else {
      conversation-driver (Book hotel)
    }
  }

The result of this is that users will see "Book hotel" even if there are no hotel results.

Similar issues can occur when the result-view block contains app-launch. For example, in this code sample, the result-view does not check the results:

Old Incorrect Way

result-view{
match: MediaActionResult(this) {
from-output : TurnUpVolume(action)
}

message ()
app-launch {
payload-uri ("bixby://com.android.systemui/DummySystem/punchOut")
}
}

New Correct Way

If you don't want the result-view to match at all and influence the output message, we recommend adding the min (Required) constraint to the match pattern for result-view:

result-view {
match: MediaActionResult(this) {
min (Required) from-output : TurnUpVolume(action)
}

message ()
app-launch {
payload-uri ("bixby://com.android.systemui/DummySystem/punchOut")
}
}

Otherwise, you should account for a no-results case with appropriate conditional logic:

result-view{
match: MediaActionResult(this) {
from-output : TurnUpVolume(action)
}

message ()
app-launch {
payload-uri {
if (exists(this)) {
template ("bixby://com.android.systemui/DummySystem/punchOut")
}
}
}
}

Changes Within "activity"

VIV-17655

For activity, we've renamed two child keys within summary-view:

  • primary is now title
  • secondary is now details

Additionally, the time key is now required.

Learn more about activities within Transactional Workflows.

Changes Within "local-endpoint"

VIV-17275

With local endpoints, you must now ensure that names between accepted-inputs and the JavaScript function parameters match.

Learn more about Local Endpoints.

New Input Component Submit Button

VIV-17226

The following input components now offer a submit-button key that allows you to customize the button text:

  • date-picker
  • calendar
  • form
  • image-picker (only used for multi-select)
  • selection-of (only used for multi-select)
  • time-picker

New Title for View Lists

VIV-17242

You can now add a header to your list of results using the title key.

New Image Text Within View Image Gallery

VIV-16512

For each image that is in image-list-of, you can now pass the title, subtitle, and caption.

18J Capsule SDK Release Notes

Updated: May 24, 2018

Sort by Preference

VIV-16167

As part of Preference Learning, once you mark a field as preferable, you can now sort results based on whether the related fields are marked as preferences.

Example:

action (Action) {

...

output (Struct) {
sort {
each (r) {
sorting (r) {
by-preferences
}
}
}
}

}

Learn more about sorting by preferences in the Developer Guide.

"background-image-url" Renamed

VIV-16894

Because the background-image-url key is used for images that are not background images, it has been renamed to image-url.

Payload Mapper for "app-launch"

VIV-16459

When using result-view, you can now specify a payload-mapper within app-launch. This lets you send a more complex payload by invoking a local JavaScript function that maps the result-view bindings and a context object into an opaque JSON string that satisfies the client's payload format requirements.

Example:

result-view {
match: MyBool (this) {
from-output: MyAction (action)
}

app-launch {
payload-mapper (lib/payload-mappers.js::myMapper)

requires { // optional
app-id (MY_APP_ID) // optional
app-min-version (12345) // optional
app-store-url (...) // optional
}
}
}

For more information, refer to app-launch in the Reference Guide.

New Resource Limits for JavaScript

VIV-17398

When using local endpoints, we now enforce JavaScript execution resource limits:

  • CPU running time: 25 seconds for each JavaScript action. This includes any aspect of the full JavaScript execution including JavaScript code bootstrap, interpretation, and function result or failure handling.

  • Memory allocation limit: 65 MB

Bixby will block violations of these limits, and they are subject to change in the future.

Selection Prompts Now Modal

VIV-17312

Selection prompts now behave modally, which means that when a user is at a selection prompt, all of their utterances will be locked to the type being prompted for. Developers can now add prompt training for user responses at selection prompts.

There are two ways in which a user utterance at a selection prompt can be interpreted normally (in a non-modal way). First, the capsule provides no training where the goal is set to the prompt type. Second, an action evaluated during execution of a prompt response triggers a flag-as-off-topic effect. If either of the two conditions are met, Bixby re-interprets the user utterance in a non-modal context, which means that all outer queries and relevant continuations are considered.

CAN Submission Reports Renamed

The following reports related to CAN submissions have been renamed:

  • NL Interpreter Training is now called Capsule Interpreter Training
  • NL Classifier Training is now called Capsule Classifier Training

The new report names are present in all new submissions starting with the 18J release, while submissions made before 18J continue to show the older report names.

18I Capsule SDK Release Notes

Updated: May 17, 2018

Highlights within View Lists

VIV-16743

You can now highlight specific results on the first page of a rendered list in the result-view and input-view of a selection list.

You can learn more about highlights (formerly smart-picks) in the Reference Guide:

"app-punch-out" Deprecated

VIV-16459

Within result-view, we've deprecated app-punch-out and replaced it with app-launch. You can now send users to a specified URI or add a more complex app-launch payload by invoking a local JavaScript function. This JS function maps the result-view bindings and a context object into an opaque JSON string that satisfies the client's payload format requirements.

Examples:

result-view {
match: MyBool (this) {
from-output: MyAction (action)
}

app-launch {
payload-mapper (lib/payload-mappers.js::myMapper)

requires { // optional
app-id (MY_APP_ID) // optional
app-min-version (12345) // optional
app-store-url (...) // optional
}
}
}
result-view {
match: MyBool (this)

app-launch {
payload-uri ("some/simple/uri?#{value(this)}")

requires { // optional
app-id (MY_APP_ID) // optional
app-min-version (12345) // optional
app-store-url (...) // optional
}
}
}

You can read more about app-launch in the Reference Guide and Bixby Views.

Sorting by Preferences

VIV-16167

You can now sort results based on whether the related fields are marked as preferences. This can be done in action concepts, collections, views, and highlights.

Example

collection {
match: Struct
default-sort-order {
sorting {
by-preferences
}
}
}

You can earn more about Sorting by Preferences.

Favorites and Natural Language Queries

VIV-15172

Because we have enabled personalized NLU classifiers, if you do not use Revision Override, users will only be able to speak naturally to capsules that are favorites. If users have never used Assistant Home to favorite anything before, they can expect all utterances that don't use named dispatch to receive low confidence ("I didn't understand that"). This affects the end-user flow and not when using Bixby Developer Studio or Simulator.

18H Capsule SDK Release Notes

Updated: May 4, 2018

Non-Standard Capsule Versioning Now Rejected

VIV-17011

With this release, Bixby rejects non-standard capsule versioning that doesn't follow a subset of the SemVer format. The capsule version must be a string with three numeric parts: "X.Y.Z". Each part must be an integer with no leading zeroes.

Correct:

1.3.24

Incorrect:

  • 1.2.3.4
    (has more than three numbers)
  • 1.2
    (has less than three numbers)
  • 1.2.3+beta
    (has a build)
  • 1.2.3-beta
    (has a suffix)
  • 0.0020.001
    (has extraneous zeroes)

Lock Screen Access to Capsules

VIV-16673

You can now make your capsule accessible at the lock screen. Additionally, you can choose which actions are accessible from the lock screen.

For more details, learn how to Grant Capsule Permissions.
