Black screen with moverio BT-200

Hi !

 

I try to develop an application for Epson Moverio BT-200 and I have some problems. I use Android Studio with gradle 1.3.0.

I try to do http://www.wikitude.com/external/doc/documentation/latest/epson/setupguideepson.html#setup-guide-epson and http://www.wikitude.com/developer/documentation/epson#_48_INSTANCE_SUygKVgNX0m5_=clientrecognition.html%23client-recognition (image on target) tutorials. I can load my application, but when I load this, I have a black screen with words "trial".

 

In my logcat, I have this message :

And in my activity_main preview, there is this rendering problem :





java.lang.NullPointerException
    at com.wikitude.architect.ArchitectView.e(Unknown Source)
    at com.wikitude.architect.ArchitectView.a(Unknown Source)
    at com.wikitude.architect.ArchitectView.<init>(Unknown Source)
    at com.wikitude.architect.ArchitectView.<init>(Unknown Source)

 

I have seen many threads, but I can't solve this problem ...

 

Thank you for your help !

Hello Alaric,

We are aware that there are some issues with Moverio BT-200 and our developers are currently working on that. As soon as there will be an update I will inform you. Thank you for your patience.

Ok, thanks for your reply !

 

I tried to do tutorials with Wikitude SDK 3.3.2 for android ( found in this thread https://support.wikitude.com/support/search/topics?term=Download+orevious+version) and it's work on my phone and on Moverio BT-200.

So, I would like to know if it's possible to access older SDK versions of Wikitude (for Android (after 3.3.2) and for Moverio BT-200), please ?

Hello Alaric,

You can find older versions for Android and iOS on our developer page. For Epson we do not have the version there, but if you need the latest stable 4.x version then we can send it once the SDK is updated to SDK 5.

Thanks!

Thanks a lot !

 

I have a last question. When will you propose the update for Epson SDK ?

Do you think it will be released before June ?

 

Thank you very much for your help !

Hello Alaric,

We are currently working on a release and we are actually on the final stage. However, we cannot yet give a specific release date but I will let you know when it is ready.

Thanks!

Ok. So, at the moment, I use the android SDK (4.1.1).

Good luck for the release ! And thanks a lot for your answers !
