1.配置gradle(Project)：
  classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

allprojects {
 repositories {
    mavenCentral()
        mavenLocal()
        maven {
            url 'https://repo.spring.io/libs-snapshot'
        }
    }
}
2.配置gradle(app):
新增：
apply plugin: 'android-apt'
def AAVersion = '版本號'

apt {
    arguments {
        androidManifestFile variant.outputs[0]?.processResources?.manifestFile（新版本寫這一句）
        // if you have multiple outputs (when using splits), you may want to have other index than 0

        // you should set your package name here if you are using different application IDs
        //  resourcePackageName "com.example.hp.myapplication"

        // You can set optional annotation processing options here, like these commented options:
        // logLevel 'INFO'
        // logFile '/var/log/aa.log'
    }
}
dependencies {
 compile 'com.android.support:appcompat-v7:23.3.0'
    apt "org.androidannotations:androidannotations:$AAVersion"
    compile "org.androidannotations:androidannotations-api:$AAVersion"
    }

     到這裡位置已經可以正常使用AndroidAnnotations,包括 @EActiivty 等.
     （注意：在使用過註解工具之後點選Build中的Make Project,
     後臺會自動生成一個比類名多一個下劃線的類，比如：MainActivity生成之後就是MainActivity_，
     這時候去MainFests中把android： name=“  "類名"中的類名後加上"_"點選Make Project就行了）

 要是使用網路Rest註解工具在gradle(app)中新增：

//新增的是為了防止重複引用
  packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }
//新增的是第三方包
dependencies {
apt "org.androidannotations:rest-spring:$AAVersion"
    compile "org.androidannotations:rest-spring-api:$AAVersion"
    compile 'org.springframework.android:spring-android-rest-template:2.0.0.BUILD-SNAPSHOT'
    compile 'org.springframework.android:spring-android-core:2.0.0.BUILD-SNAPSHOT'
    compile files('libs/jackson-annotations-2.8.0-20160517.060412-45.jar')
    compile files('libs/jackson-core-2.8.0-20160515.013135-115.jar')
    compile files('libs/jackson-databind-2.8.0-20160517.061118-256.jar')
