Instant Crash on Start after updating Unity and SDK

Hi,
I have to update a game that I released on September. During December I've formatted my hdd, so I've reinstalled both Unity and Android SDK. When I reimported the game project directoy, Unity updated it in order to be used with the new version.
I haven't modified any part of the game, but when I produce an apk, it crash on start on my device :sad:
This is very strange, because before to format, I was able to produce working apk of this game :sad:

Any idea ? :/

 

Solved I've selected OpenGL ES 2.0 from Graphic Level in Player Setting Menu
