プロジェクトで aSmack を機能させようとしています。Eclipse で標準プロジェクトを作成し、jar (smack.jar、smackx-debug.jar、smackx-jingle.jar、smackx.jar) を libs フォルダーに追加しました。XMPP クラスの使用を開始しましたが、動作していないため、プロジェクトを適切にセットアップするために他に何かする必要があるかどうかはわかりません (後で)。アプリを実行するとこのエラーが発生Could not find class 'java.beans.PropertyDescriptor', referenced from method org.jivesoftware.smack.util.PacketParserUtils.parseWithIntrospection
し、メッセージを送信しようとするとこのエラーが発生java.lang.IllegalStateException: Not connected to server.
し、at org.jivesoftware.smack.XMPPConnection.sendPacket(XMPPConnection.java:445)
これは私が使用しているコードです

XMPP クライアントでこの問題が発生したことは誰にでもあります。それはjarファイルの問題ですか、それともコード内の何かを変更する必要があるものですか...
