I’ve got a daydream app running but I’d like to play a VR Video via the google - com.google.vr.sdk.widgets.video.VrVideoView class. Is there a way to do this or a guide on how to call android/java code from UE4?
You can use JNI and UPL to call Java code from UE4. I haven’t used the VrVideoView widget so I can’t give you exact instructions but take a look at GoogleVRHMD_APL.xml for an example of how the Google VR is currently added by the plugin.
