When I user **ButterKnife** 8.4.0 an error occurs:

> 
> exception:Error:Could not find com.android.support:support-annotations:24.1.01. 
> 
>

The IDE is Android Studio 2.2, added the apt.

Here is my build.gradle:

```
apply plugin: 'com.android.application'
apply plugin: 'android-apt'

android {
  compileSdkVersion 24
  buildToolsVersion "23.0.3"

  defaultConfig {
    minSdkVersion 14
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
  }

} dependencies {
  compile fileTree(include: ['*.jar'], dir: 'libs')
  compile 'com.android.support:appcompat-v7:24.0.0-beta1'
  compile 'com.jakewharton:butterknife:8.4.0'
  apt 'com.jakewharton:butterknife-compiler:8.4.0'
}

```
