New Design for Object Table Multi Select Mode in Android

Multi-Select Mode in Android now shows check boxes instead of showing check mark inside Detail Image.

Select All and Deselect All for Object Table Multi Select Mode

MDK now supports Select All / De-Select All in multi selection using below APIs on the Object Table’s proxy class:

selectAllItems() - Select all items of unselected the section if it is in multiple selection mode.

let selectSalesOrders = context.pageProxy.getControl('SectionedTable').getSection('SalesOrderList').selectAllItems();

deselectAllItems() - Deselect all selected items of the section if it is in multiple selection mode.

let deSelectSalesOrders = context.pageProxy.getControl('SectionedTable').getSection('SalesOrderList').deselectAllItems();

getSelectedItemsCount() - Returns the number of selected items in the section.

let selectedSalesOrderCount = context.pageProxy.getControl('SectionedTable').getSection('SalesOrderList').getSelectedItemsCount();

getLoadedItemsCount() - Returns the number of loaded items in the section. This can also be used in non-multi select mode.

let loadedSalesOrderCount = context.pageProxy.getControl('SectionedTable').getSection('SalesOrderList').getLoadedItemsCount();

Please note that

- - the new APIs will allow you to select or unselect all loaded items, respectively.
  - only items that has been loaded via data paging will be selected. Items that are newly loaded via data paging will not be pre-selected even if user has previously triggered Select-All. They will only be selected if the user trigger Select-All again.

New Trace Level in Log Actions and APIs

You can now output the trace log messages to the client log file by setting the log level as Trace.

To enable logging of traces, you must also enable the TracingEnabled and Categories property in SetDebugSettings action.
Note: Traces will be tagged as DEBUG in the log file.

e.g.,

#2022-04-18 18:39:53:139 +0200: DEBUG - (0x600000510280) - SAP.OData.Offline - CallbackInternals.swift.log(_:message:) - 249 - [LOG_TAG055bd651-f91f-4e53-b9ad-456ccac44061] response: {"d":{"results":[{"__metadata":{"uri":"SalesOrderHeaders('21c24abf-9689-43e8-87fe-aa2a23c21a52')","type":"ESPM.SalesOrderHeader"},"CreatedAt":"\/Date(1648462066350)\/","CurrencyCode":"EUR","CustomerId":"1431e429-8bf8-48d3-8fca-b2c47f4ba43d","GrossAmount":"653.310","LifeCycleStatus":"N","LifeCycleStatusName":"New","NetAmount":"549.000","SalesOrderId":"21c24abf-9689-43e8-87fe-aa2a23c21a52","TaxAmount":"104.310","Items":{"__deferred":{"uri":"SalesOrderHeaders('21c24abf-9689-43e8-87fe-aa2a23c21a52')/Items"}},"CustomerDetails":{"__deferred":{"uri":"SalesOrderHeaders('21c24abf-9689-43e8-87fe-aa2a23c21a52')/CustomerDetails"}}}]}}

Dynamic Page Metadata for Tabs Control

You can now assign a dynamic page as a TabItem in your Tabs page using the PageMetadata property. You can assign a rule to this property and return a Page definition in JSON format. The definition format is the same as you get in a .page file. This allows you to dynamically build a page definition and return it from the rule to this property, instead of using PageToOpen. If this property is defined, PageToOpen will be ignored.

Draft Enabled Actions

If you are using SAP CAP OData services with Draft Enabled functionality, we now introduce below actions to work with the Draft Entities.

Improved OData Image Caching

The caching mechanism of OData media downloaded via direct OData media has been improved. If your OData back end support media ETag, MDK will help you maintain the cache and keep the media up to date. For more information, see Caching.

Additional Languages supported

MDK additionally supports below languages:

- - Indonesian (id)
  - Lithuanian (lt)

New property for your app launcher

By default, AppName property in the MDKProject.json is used as the name of the application on the home screen of the device and also the name of the folder where the MDK client is created. However,

- - You can’t display symbols in the app launcher name and
  - there is no way to specify a different name for your app launcher than the MDK client project folder.

MDK 6.2 introduces a new property AppDisplayName in MDKProject.json to address above limitations.

"AppDisplayName": "MDK#62",

For more information, please see documentation.

New property enabling default Database Encryption

Starting with MDK 6.2, EncryptDatabase property in BrandedSettings.json is no longer supported due to security consideration. It has been replaced with SecureDatabaseEncryptionKey in BrandedSettings.json.

"SecureDatabaseEncryptionKey" : true,

Please note, for security purpose, you should always set SecureDatabaseEncryptionKey to true in production scenarios. You should only set this property to false to extract the database for debugging purposes or to create a demo database.

For more information, please see Branding Your Customized App and Migration.

Client Version upgrade will prompt EULA acceptance

For custom branded client built using MDK SDK 6.2 or newer, whenever the client app's version (AppVersion in MDKProject.json) is updated, user will be prompted to accept EULA again when they launch the client app after updating it on their device.

MDK Web Preview runtime

There is now a preview runtime option available when deploying MDK metadata to Cloud Foundry that will be helpful in testing the latest release.

- - For any MDK major release, the preview web runtime will be updated first and, after two weeks, the production web runtime will be updated.
  - For any MDK patch release, both the preview and production web runtimes will be updated at the same time.

Connect to SAP Mobile Services Neo landscape

From your SAP BAS dev space, you can now connect to the app configurations from the Mobile Services Neo landscape and you can also deploy your MDK metadata project to Mobile Services Neo landscape.
