I was studying the Android Material Design using Kotlin and everything was going fine until I tried to use the android.support.design.widget.FloatingActionButton.
When I rebuild the project I got the error message below:

I saved the source files on GitHub and my environment is:
- WINDOWS 10 10.03.0.1 (64-bit)
- ANDROID STUDIO Android Studio 3.0.1 - Build #AI-171.4443003
- JRE: 1.8.0_152-release-915-b01 amd64
- JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
I tried:
- The FILE->INVALIDATE CACHE/RESTART command, but nothing changed.
- I executed the gradlew cleanBuildCache on the terminal, but it could not determine java version from '9.0.1' (?) as shown below.
gradlew cleanBuildCache --stacktrace --debug

You were referencing an attribute "textColor", when it should be "android:textColor".
In app/src/main/res/values/styles.xml replace in line 13 and line 17:
<item name="textColor">...</item> -> <item name="android:textColor">...</item>
The how: the error from AAPT stated the following:
error: style attribute 'attr/textColor (aka br.com.conseng.themedesign:attr/textColor)' not found.
It points out that you (or your libraries) are using an attribute somewhere that is not recognized. I searched for "textColor" in your repository and came up with the two attributes with the name "textColor". The widely used attribute is "android:textColor" and you didn't define the attribute "textColor" anywhere yourself, so it looked like you were missing the "android:" prefix.

Go to build.gradle(app) and add this in dependency:
implementation 'com.android.support:appcompat-v7:28.0.0'
Right now my compileSdkVersion is 28, so it is 28.0.0.
Try and change according to that.
For my situation, my compileSdkVersion < targetSdkVersion in build.gradle. Just change compileSdkVersion >= targetSdkVersion.
I've just deleted my color resourse, but it have been used in my style. So, check if your colors are really not using anywhere by Ctrl+Shift+F.

Remove this line from dependencies in gradle build file:
implementation 'com.android.support.constraint:constraint-layout:+'
