S.Galaxy 7 - Message: "Make sure APK is signed". But it's signed.

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!

You need the osig file in your project’s Build/Android/assets directory so it is packaged.
