Java.lang.UnsatisfiedLinkError: Couldn't load cocos2djs: findLibrary returned null

Hello
I have following error reports from Google Play with my game:

Java.lang.UnsatisfiedLinkError: Couldn't load cocos2djs: findLibrary returned null

This error occurs only on around 5/1000 installed devices (mainly Galaxy Ace and Galaxy Y).
My game is created with Cocos2d-x-jsb 2.1.4.
Can you help me?

its possible the App/native library wasn’t compiled for those devices.

The Release Notes are not very thorough for older versions of Cocos2d-x:

have a look at this: http://www.cocos2d-x.org/wiki/Release_Notes_for_Cocos2d-x_v300

Thanks very much for reply. I’ll test it soon.
I wonder why in this case project_creator creates Android project with manifest with minSdkVersion=8 since it doesn’t work on devices with SDK8.
It’s misleading.

Error still occurs in app created with minSdkVersion=9
