Collision Detection Approaches (Android)

Hello guys.

I just want to ask about Collision Detection and Ray Collision. Which is better to use for Android devices?
JME Collision of Bullet Physics Collision?
As far as i remember @normen said me some time ago that the Bullet Collision is faster and better than the JME Collision. This is very important for performance… That’s why i ask you guys.

Thank you.

As the native bullet wrapper is still dodgy in terms of collision but has to be used on android due to the performance of jbullet I wouldn’t exactly recommend it yet.
