Hi, Im upgrading vuforia from 3.9 to 4.2.3. I follow all examples and guides given for android studio. Hopefully i have followed everything correctly.

Im using Videoplayback from cloudReco function

Steps followed :

- new Vuforia.jar

- new (stored in jniLibs structure for studio)

In codes

- added app key param at session class intialize

- change all the ImageTracker to ObjectTracker

- change targetPositiveDimensions from  Vec2F to Vec3F

- Replace the whole utils folder from new samples

Logcat shows

 I/System.out? Native library loaded
 I/AR? QCAR has been initialized successfully
 I/AR? QCAR SDK version 4.2.3
 D/OpenGLRenderer? endAllStagingAnimators on 0x8e824080 (ListView) with handle 0x90db0510
 D/Vuforia_Sample_Applications? InitVuforiaTask.onPostExecute: Vuforia initialization successful
 I/GZCameraActivity? Tracker successfully initialized
 D/GZCameraActivity? initBooks
 I/AR? ObjectTracker: Successfully created dataset
 D/GZCameraActivity? Successfully loaded and activated data set.
 D/Vuforia_Sample_Applications? LoadTrackerTask.onPostExecute: execution successful

Issue i faced :

When i scan the object which i upload to the vuforia cloud it keep requesting and i didnt get any response.

logcat keep showing this I/AR﹕ Completed CloudReco transaction with ID '67ef6d2ec67e44528a27d3982......'

And i check the statuscode from


keep getting 1


Anyone can guide or correct me if anything i missed.

Thanks advance.

Am getting the same result. Status Code always returns 1. I checked the database access key and secret key, its correct only. Cant understand what is wrong with the code.

Check your db access key and secret keys in your code and in your vuforia account 

you can find your database access keys here

Does finder.getResultCount() return 1? If so, try using finder.getResult(0) to get the TargetSearchResult.

A value of 1 from finder.updateSearchResults() maps to UPDATE_NO_REQUEST: "No recognition request since the last update"

If no reco is happening in your app, you might want to compare to our Cloud Reco sample app. You might also want to verify that you Cloud DB keys are for the right database.
