Hi! I am trying to launch an app on Samsung Gear with S7. The packaging is ok, and I use this combination: Android minimun SDK 19, and target SDK 21. SDK api: matchndk and NDK api:android 21 But it appears this message: “Thread priority security exception. Make sure APK is signed” I don’t understand why, if I have signed the apk before. Do I need the osig file if I have apk signed? Thank you! ---

Your OSIG file (created here: [https://developer.oculus.com/osig/](https://developer.oculus.com/osig/) ) is not correctly placed. Make sure to place it in: \Epic Games\4.12\Engine\Build\Android\Java\assets ---

But, does it neccesarry if I want to share the .apk? I mean, I want to distribute it on Google Play. ---

100% necessary - you cannot distribute a gearvr app on google play. GearVR apps can only be distributed over the Oculus platform/app! If you want your app on google play you are looking at cardboard/daydream not gearvr. Then you need to add the Google VR plugin and export as a googlevr app NOT gearvr: [https://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/index.html](https://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/index.html) If you want to distribute on both then you need to export it twice differently each time for the target platform. ---

Ok, thank you! Is there any documentation on Unreal to distribute over Oculus platform? ---

Here’s the unreal quick start: [https://docs.unrealengine.com/latest/INT/Platforms/GearVR/QuickStart/index.html](https://docs.unrealengine.com/latest/INT/Platforms/GearVR/QuickStart/index.html) But for actual distribution you gotta go over the Oculus developer portal. In here you can find the mobile submission info: [https://developer3.oculus.com/documentation/publish/latest/](https://developer3.oculus.com/documentation/publish/latest/) UE4 handles most of that automatically manifest setup etc. ---
