致命异常：main java.lang.ExceptionInInitializerError引起：java.lang.NoClassDefFoundError：org.slf4j.LoggerFactory

Question

我想在我的应用程序中使用Algolia进行地理搜索。

当我将示例项目（icebnb）文件复制到我的项目。

我已经通过堆栈溢出助手清除了即时搜索模块中的一些错误。

当我打开活动（运行时）时，会引发错误。

我正面临着这个错误，并且忍受了很长时间。请帮帮我。

Answer 1

你缺少库org.slf4j.LoggerFactory类。

尝试添加以下内容取决于您的app/build.gradle文件。

compile 'org.slf4j:slf4j-api:1.7.24' 
compile 'org.slf4j:slf4j-simple:1.7.24' 

OR

您也可以下载slf4j jar文件，然后包括在app /的build.gradle为：

compile files('libs/slf4j.jar'); //You can change jar name here 

Answer 2

什么InstantSearch的Android/IceBNB的版本您使用的？

• 运行current version of IceBNB按预期工作，我可以重现你的情况的唯一方法是通过手动InstantSearch删除 SLF4J：

  compile ("com.algolia:instantsearch-android:$VERSION_INSTANTSEARCH") { 
      exclude group: "org.slf4j" 
  } 
  

这会触发你报道的那种java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory 。但除非你手动删除SLF4J，否则你不需要任何东西来让示例应用程序工作。

• 只有在您首先删除SLF4J时，接受的答案的建议才有意义。

你能分享一个触发错误的设置吗？
