使用Smack库登录

①android studio添加smack库依赖

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'
}

（

我试过下载smack的完整jar包，再手动添加，出现很多缺少第三方依赖库的情况；

再有试过添加smack4.2版本的依赖，报空指针异常

）

②登录

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        login("admin","yourpassword")
    }

    fun login(username:String,password:String){
        var addr:InetAddress  = InetAddress.getByName("169.254.235.122")
        val config: XMPPTCPConnectionConfiguration = XMPPTCPConnectionConfiguration.builder()
            .setUsernameAndPassword(username,password)
            .setXmppDomain("169.254.235.122")
            .setHost("169.254.235.122")
            .setHostAddress(addr)
            .setPort(5222)
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
//            .setSendPresence(true)
//            .setDebuggerEnabled(true)
        .build()

        Thread{
            kotlin.run {
                val conn:XMPPTCPConnection = XMPPTCPConnection(config)
                try{
                    conn.connect().login()
                    println("登录成功...")
                }catch (e:Exception){
                    println("登录错误...")
                    e.printStackTrace()
                }

            }
        }.start()

    }
}

说明：

openfire相关配置
