Build failed Error while saving blame file, Unable to merge android manifests

Hi Guys,

I wanted to build my app for Android and i got this Errors:

Error: Error while saving blame file, build will continue
Error: Le préfixe “tools” de l’attribut “tools:overrideLibrary” associé à un type d’élément “uses-sdk” n’est pas lié.

And

AndroidSDKToolsException: Unable to merge android manifests. See the Console for more details.

Ty for your help.
