在Smack 4.2.1中,使用jxmpp-core-0.5.0-alpha7。jar lib我正在获取以下问题

com.deep.tasktowerchat fatal error : No interface method lookup(Ljava/lang/Object;)Ljava/lang/Object; in class Lorg/jxmpp/util/cache/Cache; or its super classes (declaration of 'org.jxmpp.util.cache.Cache' appears in /data/app/com.deep.tasktowerchat-1/base.apk)

是smack还是jxmpp库版本问题?

你需要用相同的版本代码在你的应用程序中添加以下库。你可以下载 here 有关更多存储库和jar文件

 jxmpp-core-0.5.0.jar
 jxmpp-jid-0.5.0.jar
 jxmpp-stringprep-libidn-0.5.0.jar
 jxmpp-util-cache-0.5.0.jar

然后重建并清理项目。我希望它能起作用。
