ButterKnife 8.0.1 not working

App Level(build.gradle)

apply plugin: 'android-apt'
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'
    compile 'com.jakewharton:butterknife:8.4.0'
    apt 'com.jakewharton:butterknife-compiler:8.4.0'
}


Project Level(build.gradle)

buildscript {
    repositories {
        jcenter()
    }
    dependencies {

        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Per the readme, you need to include the butterknife-compiler in order for the generated code to be produced automatically:

buildscript {
  repositories {
    mavenCentral()
   }
  dependencies {
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
  }
}

apply plugin: 'com.neenbedankt.android-apt'

dependencies {
  compile 'com.jakewharton:butterknife:8.0.1'
  apt 'com.jakewharton:butterknife-compiler:8.0.1'
}

Without this there is no generated code to be loaded and thus none of the fields get set.

You can verify ButterKnife is working by calling ButterKnife.setDebug(true) and looking in Logcat.

I used this library in Fragment and has NPE. My code was:

ButterKnife.bind(view);

But it was wrong. Library need to know two objects:
1) Target - with annotations @BindView
2) Source - with views

It will be right to write:

ButterKnife.bind(this, view);

When this - your fragment, and view - view of this fragment.
