I have installed support library but it still I get this error. Here is how Gradle dependencies look like

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:support-annotations:23.3.0'
    compile 'com.jakewharton:butterknife:8.0.1'
    apt 'com.jakewharton:butterknife-compiler:8.0.1'

}

I have also added plugin apply plugin: 'com.neenbedankt.android-apt' and repositories

jcenter()
        mavenCentral()
        maven{
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }

Answer 1

Update Android Support Repository.
