Hi i have resolved my problem.

I have downgrade my version of jdk(1.7 ==> 1.6), and in the next time i have create a new Keystore with a jdk 1.6.
All work perfectly with this version of jdk. Ps: i work on Unity 3D 3.5.6 f4.

In order to make a build with a signed apk, you need to create a keystore file with a valid alias. (see: Sign your app  |  Android Studio  |  Android Developers)

Also, once you sign the apk, nothing can be added to or removed from the apk file.
