The Wikitude SDK 4.1 introduces a new file format for target collections (wtc). In order to unleash the full power of the new Wikitude SDK 4.1 read this section and re-generate your targets. The old format is deprecated and will be removed in future versions.
Migrate from 3.3 to 4.0
- Make sure to set the required permissions for your application when using the new
- Starting with Wikitude SDK 4.0 a valid license key is mandatory for starting the SDK. An empty license key will block the SDK. A free trial key can be generated on the license page (free account required).
- The Wikitude SDK 4.0 introduces a new file format for target collections (wtc). In order to unleash the full power of the new Wikitude SDK 4.0 read this section and re-generate your targets.
In Version 4.0 of our SDK, we changed the initialization procedure, and we open the camera immediately when the ArchitectView is initialized, to improve the overall performance. You should not call
ArchitectView.onCreate(), if you need any information about the camera, you can open (and then close) it before initializing the ArchitectView.
Any other operation on the camera when the ArchitectView is active is actually "undefined behaviour" and was not supposed to work even in previous SDK versions.
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
SensorAccuracyChangeListener are now inner interfaces of the
ArchitectView class. Update your imports in your Android code accordingly to get rid of compile time errors (
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
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.
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.
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.
|Wikitude SDK 3.x||Wikitude SDK 4.0||Wikitude SDK 4.1|
|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:
- Create a new project with the Wikitude target management tool and upload your targets (see instructions above)
- Create a target collection and store it in the same location as the previously used dataset
- In your ARchitect World, update the
AR.ClientTrackerinitialization to point to the URL of your new target collection
