Cannot find symbol R when Updating to Android 3.1.3

Yesterday i updated Android to Android 3.1.3, everything was kinda good until, today when i created a new Empty Activity and on "AppCompatActivity" showed me the error "cannot find the symbol", so then I searched and I read it had something to do with the "build.gradle", so I've been updating the libraries and got different errors, the latest one is that object "R" cannot resolve symbol. So here what I've got.

I've had many attempts to solve it (as you can see the comments in the code) but so far i haven't solve it. Please Help me!

Also in one section Android suggested me to change in the gradle.properties # org.gradle.parallel=true from false, and it didn't work either.

build.gradle

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
        //classpath 'com.android.tools.build:gradle:2.1.3'
        //classpath 'com.android.tools.build:gradle:3.2.0-alpha17'
        //classpath 'com.android.tools.build:gradle:3.1.3'
        //classpath 'com.google.gms:google-services:3.2.0'
        //classpath 'com.android.tools.build:gradle:3.1.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            //name 'Google'
        }
    }
}

Close the current project and again reopen it and rebuild solution. Most of the time by rebuilding the solution, "R cannot resolve" problem can be solved.
