Please Help: Error run VuforiaSample

December 20, 2013 - 5:57pm #1

Hi, Im chenoi,

It has been 2 weeks working on my first vuforia sdk and so far no luck for me.

I import one of the sample given into the eclipse and before I run I can see a lot of error at 'src' folder and when I click expand the folder I notice the error come from 'com.qualcomm.vuforia.*' (small red box with x) seems like it cannot import to the application. From the eclipse problem tabs, lots of error coming out namely

Area cannot be resolved to a type
CameraCalibration cannot be resolved to a type
CameraDevice cannot be resolved
CameraDevice cannot be resolved to a variable
 
Attched is the screen capture. I hope it could explain the problem.
 
I've looking around and googling but not found any solution.
 
FYI, I've pointed my enviroment variable to the vufuria root folder (C:\DEVELOPER\adt-bundle-windows-x86-20131030\Vuforia). I stuck and cannot move from here.Please somebody assist me further as I really interested to learn developing my AR using vuforia.
 
Please do assist me further. Appreciate for your kind assistance.
 
Thank you.

If you are using Android Studio (as the Gradle error message seems to suggest), you may want to check this:

When i started building apps with vuforia SDK i got this buil error as you all mentioied (Exactly)

 The solution is 

1:-attach vuforia .jar & lib/vuforia folder to your project.

2:-See the CopyvuforiaFile.xml (When you have imported the sample project)   Change the path to your development path of project  as-C:\anything\xxx\anything\Android Vuforia\build\lib\armeabi-v7a

and then compile (remove the privious data which you have compile from adv or device)

i have done this after a huge search ( this will solve your problem )

there is some problem the attach file which are shown are not attached by me.

Thanks

Hi community,
 
I had similar issue. I managed to resolve it. My mistake was that my Eclipse workspace was not in the same <DEVELOPMENT_ROOT> than the other components: Android SDK, Android NDK, and Vuforia SDK & Samples.
Solution: I created a directory in the same <DEVELOPMENT_ROOT> and pointed Eclipse workspace to this new folder.
 
I hope that it will help you.
 
Regards.

Thanks jvilgar for sharing your solution.

More in general, the path

<fileset dir="../../build/lib/armeabi-v7a"/>

is a relative path which points to the armeabi-v7a dir in your Vuforia project dir, so, this works 2as is2 if you have installed the samples at the right location under the vuforia installation dir, otherwise the path may need to be adjusted.

Hi,

i don't know why eclipse's error is with Ant Editor because when i open a file eclipse open the file with default Android editor (exactly Android Common XML Editor).

My setting configuration is:

win 64bits vista

ADT budle windows ( i run my eclipse from here like you)

vuforia 2.8( Vuforia Samples in sample directory)

 

it must be something in setting of Eclipse that there is a conflict.

it is very rare!

Thank u very much for your interest!!!

Hi,

Are you using ant editor? right click on the file and select open with ...(choice of editor).

Mine default is Android common XML editor.

Just wanna share my config. My setting as follows, 

-wins 32bit xp.

-adt budle windows ( i run my eclipse from here)

-vuforia 2.8 (vuforia sample files in this folder)

 

Hope it could give you some help.

And the libraries don't have been copied in my project.

In the CopyVuforiaFile.xml have i to change code to apply to my Eclipse or my directory tree?? I have proved in my other pc and the same error appear so i have thought that i have to change code or similar.

Indeed, Dominoes and ImageTargetsNative user the Cpp API and require to be built with ndk-build.

The other samples can be built and run in Java \ Eclipse without ndk-build.

See Getting Started Guide, as both cases are documented.

Hi Alessandro,

I've install new 2.8 and Yes! its working perfectly only got problem when run Dominoes (this required ndk build?) and ImageTargetsNative-2-8-8(this sure required ndk right?). 

I think its somethin to do with the ndk. 

For now I can run the samples except 2 file above. 

Thanks Alessandro for show me the way to resolve the issues in this thread...

Check that your sample directory is not read-only, and make sure to setup the QCAR_SDK_ROOT, as explained here.

Hi Allessandro,

Thank you for your prompt reply.

I also suspect that I'm missing some file in the package I install. There is no vuforia.jar in the lib/Vuforia directory, please refer attached. Im try to download the new 2.8 as the one I installed is 2.6. I hope this could resolve the issue I have here. 

Thank you.

Hi, those errors suggest that you have not added the Vuforia libraries to your project; in particular, you need to add the JAR file called Vuforia.jar, which you can find in the build/lib/Vuforia directory of your vuforia installation.

Note: these steps are already documented in detail in the Getting Started Guide; please read that:

https://developer.vuforia.com/resources/dev-guide/getting-started-android-native-sdk

Also, note that one week ago we released the new version of Vuforia, version 2.8, so I'd recommend to download this one, in case you are using a previous version.
