I have the same problem with Unreal Engine 4.10 and with a Galaxy S6 With Camera error… I’ll copy the log here:

About my previous error I’ll send you an email later… I don’t have my laptop here

Seems like data files are not copied to your phone. Did you use on device in the editor or installed from the packaged APK ?

Hi

I have the personal version, and I can not compile on android.

Here are the error which is also reproduced on the EU4 compilation:

To solve this problem you need to run visual studio in administrator mode.

arnaudparel · January 8, 2016, 8:38am

Hi ,

Your plugin is working great! In our studio, we just made few test and we are looking for bringing this technology working with our stuff. The first case is to bring it on a Xperia Z5, we failed to our AR project on it, it seems Unreal can’t recognize the apparel.
The second case is to lauch our AR project on 1080 HD camera (logitech C920), we don’t get result for now. Can you tell us more about futur implementation of this stuff?
Thank you.

Taurustar · January 8, 2016, 2:19pm

I already Packaged de APK and installed it…

dreamerwolf · January 8, 2016, 3:15pm

Simply one… thank !

Work perfectly on tablet Nvidia shield

blksrfc · January 11, 2016, 2:53am

Can you please re-post the ARSample:
http://get.fitnect.hu/download.php?f=tools/ARSample_1_1.zip

The original link does not seem to exist anymore:
File does not exist. Make sure you specified correct file name.

Thank you.

AdamHorvath · January 11, 2016, 3:41pm

There is a newer version on UNREAL4AR.COM

AdamHorvath · January 11, 2016, 3:42pm

Cool! I am glad it is working on nVidia Shield!

AdamHorvath · January 11, 2016, 3:59pm

Thanks! I am glad it’s working for you!

Logitech 920C

Should work on any standard web camera at least in 4:3 resolutions like 640x480 or 960x720.
Did you try to use a different device id ? What kind of problem do you experience with it ?

I am also using a Logitech camera for development without any problems. (Logitech C910)

Xperia Z5

On Xperia Z5, can you run adb logcat -s UE4 -s Debug ? Maybe you can get an error message that highlights the problem.

Regarding the future…

Currently I am working on :

v1.4 is coming soon (maybe this week) with many bug fixes, improvements :

android apk + obb fixes
controlling the camera with markers instead of the subject
documentation of each nodes / tutorial videos / docs about compiling the plugin for each platform
downloadable mobile demos

AdamHorvath · January 11, 2016, 4:05pm

I am expecting to fix this issue for packaged projects for the upcoming v1.4, for now you can run the project on all Android versions (4.4 - KitKat or above) by pressing the " on Device" button in the editor.

AdamHorvath · January 12, 2016, 7:52pm

The Android version of the MotorBike AR DEMO (apk and obb files) is available for download on the link below:

1 .Before installing make sure your android device is connected with adb devices command.
2. Extract it’s contents to a directory and run the .bat file
3. Run the ARSampleAndroid app when finished
4. Works with Hiro, and tarmac NFT markers (included in the zip)

Please help me to test it on as many android devices as possible!

Thanks,

Taurustar · January 13, 2016, 2:09pm

is there any doc about how to make my own Image Target to deploy an AR?

AdamHorvath · January 13, 2016, 4:25pm

Fiducial:

NFT:

Once you have your new marker files copy them into your AR project’s Content/ARToolkit/Data or DataNFT directory, and add them to Markers or MarkersNFT enumerations

Baesky · January 13, 2016, 4:39pm

Hi, I bought your item but when I download it, show up: Sorry, you have reached your download limit for this file Go to homepage.

AdamHorvath · January 14, 2016, 9:30am

Hi,

Please send me an email to info@unreal4.com with your order details.

Thanks,

gameDNA · January 14, 2016, 5:40pm

OMG! This is awesome! I’ll buy it definitely

Taurustar · January 15, 2016, 4:27pm

How can you change the actually behaviour after detection? because I see with NFT it doesn’t ask you about if the AR is visible or not… I want to show a UI with my AR target, any clues about how to achieve that?

blksrfc · January 16, 2016, 8:06am

I am sorry but I still can’t seem to find the UE4 Sample Project (Chairs demo) anywhere in the commercial link I was sent.
Also I am experiencing the following when double clicking either the or Fighting Demo…
“AR Toolkit is not properly initialized; Possible Wecam Init Error; Webcam init error”
This has happened with my laptop camera as well as my desktop Logitec 1080.
I am an program newbie, so please forgive me and thanks in advance.
My AR Toolkit demo worked without issue.

Thanks

AdamHorvath · January 18, 2016, 4:10pm

Can you please send me your log files ? PROJECT_DIR/Saved/Logs ?
Also please make sure there are no special characters in the path. For example try to run one of the executable demos from c:\ARDemo
