Migrate from 4.1 to 5.0

Migrate from 4.0 to 4.1

Migrate from 3.3 to 4.0

Migrate from 3.2 to 3.3

The SDK is compatible with Android 4.4, so we recommend to update ADT to the latest version and set the target SDK version to '19' in your Android Manifest XML file.

Migrate from 3.1 to 3.2

ArchitectUrlListener and SensorAccuracyChangeListener are now inner interfaces of the ArchitectView class. Update your imports in your Android code accordingly to get rid of compile time errors (ArchitectUrlListener becomes ArchitectView.ArchitectUrlListener).

Migrate from 3.0 to 3.1

Image Recognition and Tracking

The image recognition engine of Wikitude SDK 3.1 has been updated resulting in shorter time interval to successfully recognize a target image. As a consequence the format of the digital footprint of target image has changed. The format is backward compatible. Developers still can use target collections (.wtc) generated with Wikitude SDK 3.0 (prior to 27th August 2013) together with the SDK 3.1 and vice versa.

However we recommend to generate your target collections again in the Target Manager Tool and update the files when you are using Wikitude SDK 3.1

HTML Drawables

Developers using HTML Drawables in projects prior to Wikitude SDK 3.1 and like to upgrade to 3.1 need to define the viewportHeight similar to the already defined viewportWidth. In addition HTML Drawables do not have to be created as static or dynamic anymore. All are created as dynamic ones.

Migrate from 2.0 to 3.0

Wikitude SDK version 3.0 introduces Wikitude's own image recognition and tracking solution and removes support for the Vuforia Plugin.

If you are not using image recognition features in your app you only need to update the jar file and are good to go.

In case you are making use of image recognition features and want to switch from 2.0 to 3.x version remove any Qualcomm/Vuforia related assets (QCAR.so, QCAR.lib) from your project. Also the READ_PHONE_STATE permission is no longer required in your AndroidManifest.xml.

Upgrading targets for SDK 4.1

The Wikitude SDK 4.1 introduces an updated format for the target collection. The new format improves the recognition phase considerably. The updated format is not backward compatible with Wikitude SDK 3.x, 4.0 and can not be used in projects using Wikitude SDK 3.x or Wikitude SDK 4.0.

However you can use wtc-3.x and wtc-4.0 formats with the Wikitude SDK 4.1, although we strongly recommend to updated to the newest (wtc-4.1) version.

Support for wtc-3.x and wtc-4.0 is deprecated and will be not supported in Wikitude SDK 5.0 (later 2015).

To use the new format you need to re-create your target collection in the target manager and download the .wtc file under the Download 4.1 link. Put this .wtc file in your app and replace the previous one.

It is not possible to use a wtc 4.1 file together with Wikitude SDK 3.x or Wikitude SDK 4.0. Please download the respective wtc versions from the target manager and use them.

Wikitude SDK 3.x Wikitude SDK 4.0 Wikitude SDK 4.1
wtc 3.x supported supported supported
wtc 4.0 not supported supported supported
wtc 4.1 not supported not supported supported

Migrating targets from SDK 1.x

If you have been using a dataset from the Qualcomm Vuforia target management, please follow these steps to convert your ARchitect World to the new approach:

  1. Create a new project with the Wikitude target management tool and upload your targets (see instructions above)
  2. Create a target collection and store it in the same location as the previously used dataset
  3. In your ARchitect World, update the AR.ClientTracker initialization to point to the URL of your new target collection
