smack现在已经支持Android了，Android Studio已经成为主流Android开发IDE了，本文就介绍一下，如何在Android Studio 使用smack。

很简单，使用Android Studio导入smack就可以了

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

在Android Studio中，只需要将这段代码复制进build.gradle(Module: app)中就行，注意，repositories {} 与 android {}、dependencies {} 同级。

Smack configuration with smack-extensions for XMPP over TCP

dependencies {
  compile "org.igniterealtime.smack:smack-android-extensions:4.3.0"
  compile "org.igniterealtime.smack:smack-tcp:4.3.0"
}

configurations {
	all*.exclude group: 'xpp3', module: 'xpp3'
}

Minimal Smack configuration for XMPP over TCP

dependencies {
  compile "org.igniterealtime.smack:smack-android:4.3.0"
  compile "org.igniterealtime.smack:smack-tcp:4.3.0"
}

configurations {
	all*.exclude group: 'xpp3', module: 'xpp3'
}

这两段的含义是如何选择依赖项，前一个表示带有扩展的smack包，后一个表示最小化配置。

还可以选择带有实验特性的依赖包，如下：

Smack configuration with experimental extensions (XEP-0280, XEP-0352, XEP-0332, XEP-0335)

dependencies {
  compile "org.igniterealtime.smack:smack-android-extensions:4.3.0"
  compile "org.igniterealtime.smack:smack-experimental:4.3.0"
  compile "org.igniterealtime.smack:smack-tcp:4.3.0"
}

configurations {
	all*.exclude group: 'xpp3', module: 'xpp3'
}

在这里本人选取第一个，最终修改的Gradle文件如下：

apply plugin: 'com.android.application'

android {...}

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

dependencies {
    compile "org.igniterealtime.smack:smack-android:4.3.0"
    compile "org.igniterealtime.smack:smack-tcp:4.3.0"
    ...
}

configurations {
	all*.exclude group: 'xpp3', module: 'xpp3'
}

写到这边Gradle文件就算修改好了，然后一定要点击图中的同步按钮，Android Studio才会自动下载smack。
