I'm new here, so feel free to give tips where needed. I am running into trouble using the Unreal engine combined with the HoloLens 2.
I would like to access the special black/white cameras of the HoloLens, for tracking purposes. These are normally not accessible. However, they can be activated by using the “perceptionSensorsExperimental” capability. This should be possible, since it also works with Unity: https://github.com/doughtmw/HoloLensForCV-Unity
I have tried to add the capability in the Unreal Project Settings: Config\HoloLens\HoloLensEngine.ini” -> “+RescapCapabilityList=perceptionSensorsExperimental”. The project still builds as expected, but I noticed that it doesn’t matter what I add here. Even something random like “+abcd=efgh” doesn’t break the build.
However, if I add “+CapabilityList=perceptionSensorsExperimental”, I get “Packaging (HoloLens): ERROR: The 'Name' attribute is invalid - The value 'perceptionSensorsExperimental' is invalid according to its datatype 'http://schemas.microsoft.com/appx/manifest/types:ST_Capability_Foundation' - The Enumeration constraint failed.”. I conclude: 1.) I’m making the changes in the right file. 2.) The right scheme needs to be configured in order for “+RescapCapabilityList=perceptionSensorsExperimental” to work as expected.
My question is how do I add the right schema to my Unreal project? (like in the Unity example referenced above, which uses “http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities”), I cannot find any example and I cannot find any proper place to put it. Not in the settings, not in the xml/ini files. Clearly, I am missing something.
Any thoughts are much appreciated!
Updated. We released HoloLens-ResearchMode-Unreal plugin

I'm trying to build grapheneos for pixel 6 with custom bootanimation.
I created the bootanimation.zip file according to instructions but can't figure out the location to put it in. Since the usual location, system/media/bootanimation.zip is giving me an Error:
offending entries: system/media/bootanimation.zip
besides this, the build also fails.
Can anyone help me to understand what I am doing wrong ?
Error message
If it is still relevant, I may have an answer for you.
There's a mechanism that prevents you from doing something to the system partition from the product makefile in some cases.
The solution to your specific situation might be different, and there are also suggested solutions in the link below.
If you have something that is a part of the system partition, and is not a product specific thing, you can also add it to:
build/make/target/product/generic_system.mk
instead of the product specific makefile
Here is a link explaining this mechanism
I am developing an android app where I have to train my app to recognize two images and four objects.I created one single database where I added all the images and objects target in vuforia developer site and created the unity package. Now neither image nor object is getting recognized.
Probably the problem is the same for objects and images.
I think you should share some more info about what your doing as well as some meaningful code implementing it.
W/O that, I would suggest:
verify that the database and trackables are loaded and active # runtime
if so, see in console that the trackables are tracked by Vuforia
if so, verify the code enabling your augmentations
Please confirm whether have run trough these steps already and what results you got. I can share some code and further tips once the issue is a little but more specific.

I am using a Oculus DK2 (v0.8) and OSVR SDK. I'm having a problem getting the HMD to run/display anything.
The Oculus samples and the OSVR samples do work however, so the osvr_server seems to run fine.
My application itself renders a test scene just fine when not using a HMD.
I tried two approaches:
First, just creating a osvr context and creating a DisplayConfig object. This seems to work, but DisplayConfig::checkStartup() fails (I do this in a loop, calling update on the context when the checkStartup call is failing). I used the OpenGLSample.cpp as a guide for this
Second, I tried using a RenderManager, but the call to createRenderManager results in a crash within the RenderManager.dll. I get the same crash wether I create the graphics lib object myself or if I let the library create it.
I am quite stuck now, since the demos and examples do work, I have no idea where to look for the error on my side. Creating the context works, querying interfaces as well, but the crash with createRenderManager is beyond me.
Does anyone have any hints or ideas what the problem could possibly be?
Regards and thanks in advance

RenderManager should not crash during open. There have been a couple of bug fixes recently to avoid that happening, and the latest RenderManager binaries, libraries and header files are available with the SDK download from http://osvr.github.io/using/ along with updated copies of the example programs.
When something goes wrong in RenderManager, it usually reports that to standard error. We're moving that to a logging interface, but for now it should show up on the console. Posting an output of that as an issue at https://github.com/sensics/OSVR-RenderManager/issues is a good way to let the developers know that there is a problem. Of course, providing the same sort of information you provided here will be helpful as well.
I'm trying to use Unity's excellent new CrossPlatformValidator
(Such as seen ...
http://docs.unity3d.com/Manual/UnityIAPValidatingReceipts.html or
https://docs.google.com/document/d/1dJzeoGPeUIUetvFCulsvRz1TwRNOcJzwTDVf23gk8Rg)
But it can't be found! Naturally I am ...
using UnityEngine;
using UnityEngine.Purchasing;
I also tried different stripping and .Net levels. Nothing.
Anyone have a clue about this?
The type or namespace name `CrossPlatformValidator' could not be found. Are you missing a using directive or an assembly reference?
Stuff like this is usually found at UnityEngine.Experimental but it wasn't there when I looked so I guess it is not a new feature.
1. You can find it by going to Windows -> Services. Sign in on the Window displayed, usually on the right.
2. Create a Project ID on that Window.
3. Click on In-APP Purchasing. It is checked to OFF, click on it then click Enable.
Note: You must Sign in to be able to Enable it and you must Enable it before you can use it from Script.
Finally, the completely undocumented namespace is:
using UnityEngine.Purchasing.Security;
note that one can see this in the generated "tangle" files, for example, if one forgets it. :/
Mono Dev can often help you find things.
Right click on unresolved class -> Resolve

I’m developing for android jelly bean and I would like to add a field to the network settings menu, but can’t seem to find it in the android source code….
I’ve looked in packages-apps-settings-src-android-settings but then didn’t know exactly where to look.
Can anyone help me please?
You should first have a look at the packages/apps/Settings/res/xml/setting_headers.xml file which list the different categories used in the Settings app.
Then, you can implement a new category by looking how others are implemented - for example the "Data usage" setting is implemented in src/com/android/settings/DataUsageSummary.java (the fragment is referenced from the setting_headers.xml file).
