XMPP登録ログインとチャットの簡単な例

XMPP登録ログインとチャットの基本的な例

あなたのシステムやサーバにopenfireやチャットサーバをインストールしてください。詳細はこちらをクリックしてください。

androidプロジェクトを作成し、これらのライブラリをgradleに追加します：

compile 'org.igniterealtime.smack:smack-android:4.2.0'
compile 'org.igniterealtime.smack:smack-tcp:4.2.0'
compile 'org.igniterealtime.smack:smack-im:4.2.0'
compile 'org.igniterealtime.smack:smack-android-extensions:4.2.0'

次に、xmpp接続目的から1つのxmppクラスを作成します。
