Unable to build Espresso server, for the umpteenth time.

[russtu]

Appium Version :2.2.0
Espresso driver version: 2.26.10

Building my app I have no problem and launching it on a tablet either, when trying to launch it with the espresso driver and having already put in "espressoBuildConfig" all my dependencies, I still have problems, I went from having the error "no virtual method" to, once I put all my dependencies, in the json, to have these errors :

 * What went wrong:
[EspressoDriver@8db9 (6fbabff6)] [Gradle] [STDERR] Execution failed for task ':app:processDebugMainManifest'.
[EspressoDriver@8db9 (6fbabff6)] [Gradle] [STDERR] > Manifest merger failed : Attribute data@scheme at AndroidManifest.xml requires a placeholder substitution but no value for <appAuthRedirectScheme> is provided.
[EspressoDriver@8db9 (6fbabff6)] [Gradle] [STDERR] 

I have "appAuthRedirectScheme" defined in "manifestPlaceholders" in android/defaultConfig in my build.gradle, and also deficido in the AndroidManifest.xml , other than that my app works fine and launches fine with no problems, but with espresso it doesn't.

I think I'm going to give up, if it's not one bug , it's another. Too many configurations for my knowledge I think.
I don't know if there is anything else I can miss as a last test, if not I'm out, I only got appium settings to install, then my application, but only a small one second view of the first screen before crashing.
