artijn Posted April 26 Share Posted April 26 Hello all, I'm encountering problems with running the Unreal VR template as stand alone app on my Vive Focus 3. Whenever I try to open a packaged .apk on the device, the app terminates and brings me back to the library, without any further notification. I followed all instructions provided in the documentation. https://developer.vive.com/resources/openxr/openxr-mobile/documentation/ The issue occurs both for Unreal 5.0 and 5.1 with the OpenXR plugin enabled. I can still successfully build android apps in Unreal 5.0 using the WaveSDK plugin. Is this occurring to more people? Link to comment Share on other sites More sharing options...
artijn Posted May 7 Author Share Posted May 7 I still haven't been able to resolve the above issue. Initially I was able to successfully launch the APK on the device using Unreal 5.1. Then I made changes to the android configuration on my pc, a.o. running the SetupAndroid.bat for Unreal 5.0 and 5.2 preview. This included referring to version 8.0 for the Command-Line Tools, as per item 3 of documentation https://docs.unrealengine.com/5.1/en-US/how-to-set-up-android-sdk-and-ndk-for-your-unreal-engine-development-environment/ . The issue now only occurs for Unreal 5.1, UE 5.0 works fine. The issue also occurs when using a different PC. A factory reset of the VR device didn't resolve.

artijn Posted May 10 Author Share Posted May 10 (edited) It's working again. One of the following might have resolved it: Refesh libopenxr_loader.so (Documentation Ch. 3.2 step 1). I might have overrun it when I performed the Verify option on the Unreal installation. Update Java to 1.8.0_351 (link in documentation Ch 4.1.3 refered to 1.8.0_202, if that matters) Edited May 10 by artijn Link to comment Share on other sites More sharing options...
