FATAL EXCEPTION: main java.lang.ExceptionInInitializerError Caused by: 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时。

我已经在堆栈溢出助手的帮助下清除了即时搜索模块中的一些错误错误。

当我打开 activity（运行时）时出现错误。

我正面临这个错误并且遭受了很长时间的困扰。请帮助我。

Answer 1

您缺少 class org.slf4j.LoggerFactory.

的库

尝试根据您的 app/build.gradle 文件添加以下内容。

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

或

您还可以下载 slf4j jar 文件，然后将其包含在 app/build.gradle 中，如：

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

Answer 2

您使用的是哪个版本的 InstantSearch Android/IceBNB？

运行 current version of IceBNB 按预期工作，我可以重现您的情况的唯一方法是 从即时搜索中手动删除 SLF4J :
```
compile ("com.algolia:instantsearch-android:$VERSION_INSTANTSEARCH") {
    exclude group: "org.slf4j"
}
```

这会触发您报告的 java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory。但是除非你手动删除 SLF4J，否则你不需要任何东西就可以让示例应用程序正常工作。

接受的答案的建议只有在您首先删除 SLF4J 时才有意义。

能否分享触发错误的设置？
