New Features and Enhancements Mobile Development Kit Client 26.3.0

Introduction of PreferredCaptionSize Property in Action Bar

The Action Bar now supports flexible caption sizing through the new PreferredCaptionSize property, which replaces the existing PrefersLargeCaption property. This new property PreferredCaptionSize lets you set the Action Bar caption size to "Small", "Medium", or "Large".

Note:

  • iOS supports small and large caption size
  • Android supports small, medium, and large caption size.

Behavior Notes:

  • When PreferredCaptionSize is set to "large", any defined Subhead will be ignored.
  • When setting CaptionAlignment (Android only) to "center", the PreferCaptionSize automatically set to small.
  • On iOS, large caption mode is not supported on pages with BottomNavigation, Tabs, SideDrawer, FormCellContainer, or FlexibleColumn controls.

  • If both PreferredCaptionSize and the deprecated PrefersLargeCaption property are specified, PreferredCaptionSize takes precedence.

  • For more information, refer to the ActionBar topic.

Enhanced Troubleshooting with Offline Store Upload

  • A device's offline store can be valuable for troubleshooting issues in some cases. This new feature enables you to send the offline store (Both the main offline database (UDB) and the Request Queue database) to the server, assisting in the diagnostic process. To facilitate this capability, a new MDK action has been introduced: Action.Type.OfflineOData.UploadStore. This action includes optional parameters, such as a temporary encryption key and a note for additional context.

  • Before utilizing this feature, you must enable the Offline Store Upload Policy in SAP Mobile Services Admin UI for a given MDK app. Note that there is a maximum database size restriction of 1024 MB.

  • For more information, refer to the Working with Offline Stores topic.

RequiredIndicator Support for Segmented Form Cell

  • The Segmented Form Cell control now supports RequiredIndicator, enabling you to add a mandatory field indicator to show that this form cell must be filled. This indicator is visual only and does not enforce validation; it indicates that the field is required. The default indicator is an asterisk * placed at the end of the caption or title. You can customize the indicator by specifying a different single character in the metadata using the RequiredIndicator property. Only one character is allowed for customization. If you define more than one, the control defaults to the default asterisk indicator *.

  • You can apply custom styling to the indicator using the Styles property with the style name RequiredIndicator. This is supported through style classes, and you can set the indicator color using the font-color or color property.

Onboarding via MDM App Configuration (Managed Configuration)

  • Onboarding via MDM App Configuration (Managed Configuration) is now supported. This feature streamlines the deployment and management of MDK clients by enabling administrators to push configuration settings directly through their MDM solution (for example, Microsoft Intune). The MDK client retrieves configurations from the MDKSettings root property within the Managed Configuration, which currently accepts the ConnectionSettings object. Managed Configuration is prioritized fourth in the ConnectionSettings hierarchy, after URL/QR Scan, Local Overrides, and previous connection settings from URL/QR scan after successful onboarding, but before Branded Settings and Default Settings. The EnableOverrides property controls whether settings can be replaced by Overrides.json or manual onboarding via QR code or URL. Set EnableOverrides to false in Managed Configuration to prevent replacements. The MDK client re-evaluates Managed Configuration settings when you log out or restart the app while logged out. Important: Previous connection settings from URL or QR code persist after successful onboarding, regardless of EnableOverrides or Managed Configuration updates. You must reinstall the application to clear them. To prevent this, set EnableOverrides to false initially.

  • For more information, see Onboarding to the Mobile Development Kit Client App topic.

Support In-App Camera in AttachmentFormCell (Android Only)

  • Introduced a new property in the Application.app file (under Settings object). This new property, UseInAppCamera, is of type boolean; by default, it is set to false. This flag determines whether to use the in-app camera for the AttachmentFormCell control's "Take Photo" option. If set to true, the in-app camera would be used instead of the device's default camera.

  • We have also introduced two new APIs. The first one is getUseInAppCamera, to get the current value of this flag. This method is to get the current state of usage of in-app camera for Android Attachment form cell control. The second one is setUseInAppCamera. This method enables or disables the use of the in-app camera for the Android Attachment form cell control. The new value will be effective immediately. Specifically, for already rendered attachment form cell controls on the current page, it will only take effect after being reset via the control's reset() API. Note that calling the control's reset() API will discard the existing attachments.

  • For more information, see the getUseInAppCamera topic.

Add Styling to KeyValueItem Control for iOS and Android

  • The purpose of this feature is to add a new Styles property to the KeyValueItem control and to its two sub-controls: KeyName and Value. For KeyValueItem, the Styles property applies to the entire item and supports only the background color. For KeyName and Value, each sub-control accepts a style class string and supports standard label/text styling properties, such as font-size, font-color, color, and others. Please note that Value style will take priority over LinkColor, regardless of whether OnPress is defined or not.

  • For more information, see the KeyValueItem topic.

Support for Initials in Contact Cell Component

  • The Contact Cell component on iOS and Android now supports displaying user initials, providing a more personalized and recognizable visual experience when profile pictures are unavailable. This enhancement makes it easier to scan and identify contacts, replacing generic placeholder icons with meaningful initials.
  • Three new properties have been introduced to support this feature. The DetailImageText property is a string that displays text in the image container when no detail image is present, showing 2-4 characters maximum, allowing you to manually specify custom text such as initials. The DetailImageIsCircular property is a boolean with a default value of true that controls the shape of the image container — when set to true, the image displays in a circular shape, and when set to false, it displays in a rounded rectangular shape. The UseHeadlineForDetailImage property is a boolean with a default value of false that, when set to true and no DetailImage is provided, automatically extracts and displays the first two initials from the Headline property in the image container; this property takes precedence over DetailImageText.
