Fix breaks due to Gradle 3 upgrade?

I am so glad you took the time to create this example. Unfortunately, after forking then cloning this project onto my Mac 10.13.1, opening the project within Android Studio 3.0.0, seeing ADB appear, I got this error message:

Error:Execution failed for task ':app:javaPreCompileDebug'.
> Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - butterknife-6.1.0.jar (com.jakewharton:butterknife:6.1.0)
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.
  See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

I Googled the messages and found: https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html?utm_source=android-studio#annotationProcessor_config

https://stackoverflow.com/questions/42993587/setting-explict-annotation-processor

So I editing the project-level build.gradle file to end up with classpath ‘com.android.tools.build:gradle:3.0.1’

Then I clicked Sync.

In gradle-wrapper.properties I have: distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

Following [(https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html#annotationProcessor_config] I added:

    annotationProcessor 'com.jakewharton:butterknife-gradle-plugin:6.1.0'

But this resulted in errors as well. So I’m lost here. Suggestions?

This helped me solve the error. I found it here dependencies { compile ‘com.jakewharton:butterknife:8.8.1’ annotationProcessor ‘com.jakewharton:butterknife-compiler:8.8.1’ }

@bradley-curran I am able to build your fork but the tabs in Menu > Input Controls screen are not visible, hence the automated tests (Espresso) fail. Here’s is my fork to fix it: https://github.com/choozm/aws-device-farm-sample-app-for-android/tree/fix/PagerTabStrip
