I've searched on the internet for solution but with no success.

HOW TO CHANGE THE ANDROID UGLY BLACK DEFAULT THEME DEFINED IN MANIFEST IN AN ANDROID CROSSWALK APP ?
Fab -- we do not support hooks (at this time) because they are a security threat for the build system and for your accounts and data. A hooks script can include any code, there are no restrictions. That means that a nefarious developer can use them to take over the build servers and potentially gain access to your application assets and account information. That restriction is there to protect your account and private information.
We are working on a build system solution that would allow for hooks scripts, until that build system is available we must restrict their use.
Unfortunately, there is no way to use a plugin to easily modify that aspect of the XDK build system, due to the reason you outline, because it can only append, not replace.
