100.2.1
Version 100.2.1 of ArcGIS Runtime SDK for Android is a minor update to 100.2.
Enhancements
WMS
- Runtime now supports using URLs without a 'GetCapabilities' query string.
- Runtime now supports WMS versions 1.1.0, 1.1.1, and 1.3.0. Previously, only 1.3.0 was supported.
- You can now set the visibility of WMS sublayers.
Mobile Map Packages
- This release supports mobile map packages that contain raster datasets and tile packages. These mobile map packages can be created with version 2.1 of ArcGIS Pro. If you load an mmpk's map (explicitly or by passing it to the map view) a RasterLayer or a ArcGISTiledLayer will be created to display the raster dataset and tile package, respectively.
- To access the mobile maps package's raster dataset you need to unpack the mobile map package first.
3D scene support for tiled layers in WGS84
3D scenes now support the use of WGS84 based tiled layers as a basemap or layer. Scenes in ArcGIS Runtime 100.2.0 supported only tiled layers in the Web Mercator projection.
100.2
Version 100.2.0 of ArcGIS Runtime SDK for Android, also known as Update 2, is the second major update to 100.0.0. This topic describes what's new, provides a list of known limitations, and more.
Enhancements
New layers
A new WMS layer is available that can display content from OGC-WMS Services in maps and scenes. You can identify features that are displayed, and generate a legend for them. Only WMS version 1.3 is supported at this release, but support for other versions will be added in a future release.
A new ENC layer is available that can display content from ENC (Electronic Navigational Charts) data in S-57 format. ENC is a vector chart that conforms to the IHO specifications contained in Publication S-57, which is a transfer standard for vector data. The Runtime implementation follows the S-52 Presentation Library 4.0 specification for rendering. You can identify features that are displayed, select features, and change various display settings for view groups, text, and other elements such as isolated dangers, contours, color scheme, etc. Support for the encrypted S-63 format will be added in a future release.
New data formats
Direct read of Shapefile datasets is now supported. Shapefiles can be added as a feature layer for display in maps and scenes. You can also add and edit features in the dataset through the shapefile feature table.
Support for the OGC GeoPackage format has also been added at this release. You can add vector and raster datasets in a GeoPackage to your maps and scenes as feature layers and raster layers respectively. You can also add and edit features in an existing GeoPackage feature table.
Rendering improvements
Feature layers can now be rendered dynamically in addition to statically, just like graphics overlays. You can set the rendering mode at the map or scene level via load settings, or on a layer by layer basis at the feature layer level. Dynamic rendering improves the appearance and interactivity of features during map or scene navigation. Feature layers containing point geometries are rendered dynamically now by default and their symbols remain screen-aligned in map views and will be "billboarded" in scene views. Feature layers containing polygon or polyline geometries are still rendered statically by default, but you can choose to render them dynamically to allow for 3D behavior such as extrusion based on feature layer attributes and surface placement based on z values.
Display performance of graphics overlays has also been improved when updating large volumes of graphics. In some cases, the performance as a measure of frame rate is 2x faster compared to previous releases.
New multi-layer symbol types have been introduced to better represent working with feature layers that contain advanced cartography. At this release, these symbol types cannot be created by developers but can be authored in ArcGIS Pro and deployed through feature services, Mobile Map Packages, and Mobile Style files for use in the runtime. In future releases, these symbol types will be further expanded so that developers can produce sophisticated cartographic effects by combining multiple symbol layers.
Analysis
With the new Scene Analysis API you can define a variety of analyses to be performed using data displayed in the current 3D scene view, then render results that are updated dynamically. This release includes two types of scene visibility analyses: viewshed and line of sight. Viewshed highlights areas in your 3D scene that are visible from a given observer. Line of sight shows which segments are visible along a line drawn between an observer and a target location. For either type of analysis, the observer and/or target may be moving or stationary.
The new statistics query API allows you to get any of the following statistics for a specified field in a feature table: Sum, Average, Count, Minimum, Maximum, Standard Deviation, or Variance. In the statistics query parameters, you can define filters for features to include in the statistics (based on attributes, spatial relationships, or time extent) as well as how the results are grouped and sorted.
Coordinate systems and transformations
Geographic transformations (or datum transformations) can now be discovered, defined, used in project function of the geometry engine class, and chosen to be used by default. Prior to this release, the most suitable transformations have been used automatically whenever data is projected. A new transformation catalog class lets you look up a list of the best transformations to use when projecting between two spatial references that have different datums. The new method, getTransformationsBySuitability, provides a list of applicable transforms for the two spatial references you provide, ordered by suitability. You can even pass in a specific envelope to get back transforms suitable for that specific area. You can define a transformation by well-known ID (WKID) or create a custom transformation using well-known text strings. You can also change the default transformation that is used internally via gtdefaults_overrides.json. Both equation-based and grid-based transformations are supported. You can use isProjectionEngineDataMissing to determine whether required grid transformation data files are missing. The grid transformation files needed by your app can be downloaded from the downloads page. Read more about geographic transformations in the topic Spatial references.
Offline Maps - Preplanned workflow
This release enhances on-demand workflows with support for exporting and downloading vector tile packages from vector tile map services hosted by ArcGIS Online or ArcGIS Enterprise. Vector tile packages contain a default style to define how tiles are rendered. Vector tile layers can also reference custom styles as resources in a portal item. This release also supports downloading and applying custom style resources to vector tile layers on the client.
This release expands your ability to take maps offline with the new preplanned workflow. Offline maps allow your users to continue being productive even when their network connectivity is poor or non-existent. The preplanned workflow supplements the existing ondemand workflow by providing an alternative approach of allowing the map author to define and pre-create offline map areas instead of the field worker. Your field workers can then download map areas as required. With both of these offline workflows, the field worker can synchronize any updates to operational data when connectivity is restored.
Transactional editing
Transactional editing is now supported in the geodatabase and geodatabase feature tables. This allows you to perform a number of edits and then choose to commit all of them together as one unit, or roll them all back if any of them encounters an error. Nested transactions are not currently supported.
###Localization Directions returned by route task are available in 10 additional languages - Danish, Finnish, Hindi, Croatian, Indonesian, Norwegian Bokmål, Romanian, Serbian, Vietnamese, and Chinese (Taiwan). If the requested language isn't available, directions fall back to a default language instead of failing. Furthermore, error messages returned by Route, Service Area, and Closest Facility tasks are now consistent and translated into all supported languages. As part of these changes, some DirectionMessage types (Length, Time, Summary, TimeWindow, ViolationTime, ServiceTime, EstimatedArrivalTime, CumulativeLength) are no longer reported. These messages did not respect platform locale settings for formatting numbers, dates, and times messages, and the information they contained is available through other properties in the results.
Raster mosaics
Mosaic raster datasets can now be created on-the-fly. Once created, raster files can be added to them asynchronously. Have a look at the additional methods exposed on the MosaicDatasetRaster class Kotlin The Kotlin programming language is now supported. Kotlin code snippets have been added to this guide and Kotlin samples have been added to the Android SDK samples repo.
Deprecations
The previously deprecated constructor RouteTask(String) has been removed. Use the alternative constructor RouteTask(Context, String) instead, passing in the current Android Context in addition to the URL of the routing service.
