Question

我想在我的应用中使用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。

我已经通过堆栈溢出助手的帮助清除了即时搜索模块的一些错误错误。

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长期受苦。请帮帮我。

Answer 1

您使用的是什么版本的InstantSearch Android / IceBNB？

运行current version of IceBNB按预期工作，我能够重现您情况的唯一方法是从InstantSearch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。但除非你手动删除SLF4J，否则你不需要任何东西让示例应用程序正常工作。

如果您首先删除SLF4J，则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？

Answer 2

您缺少课程org.slf4j.LoggerFactory的图书馆。

尝试根据 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'

OR

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

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

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