统一修改版本号：

根 build.gradle

ext{
    //SDK  tools
    minSdkVersion = 15
    targetSdkVersion = 24
    compileSdkVersion = 24
    buildToolsVersion = '24.0.1'

    // app dependence
    supportLibraryVersion = '23.4.0'
    butterknife = '8.2.1'
    guava  = '19.0'

}

app build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        applicationId "com.example.hante.newnetpas"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile "com.android.support:appcompat-v7:$rootProject.ext.supportLibraryVersion"

    //注解
    compile "com.jakewharton:butterknife:$rootProject.ext.butterknife"
    compile "com.google.guava:guava:$rootProject.ext.guava"


}

1.自动生成注解：

https://github.com/JakeWharton/butterknife
http://jakewharton.github.io/butterknife/
Alt+insert 注解 Generate Butter Knife

or Gradle:

 compile 'com.jakewharton:butterknife:7.0.1'

最新版本8.01 会报空指针异常

官方说明下面有这么一段：

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'
}

build.gradle文件更改了一下：

运行时发生：

暂时没找到解决办法，只能先用7.01了

2.Guava: Google Core Libraries for Java

https://github.com/google/guava

dependencies {
  compile 'com.google.guava:guava:19.0'
}
