Android：YelpAPI访问错误

我想显示使用Yelp API中当前位置的餐馆列表。对此很少或没有明确的帮助。我正在尝试各种可能的方式来获得结果，但无法得到它。我只是Android的初学者。Android：YelpAPI访问错误

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/commons/codec/BinaryDecoder.class

该流程应该像MainActivityFragment一样，它应该显示一个距离我当前位置一英里范围内的餐馆列表。

我终于解决了这个问题。 – Nick

我能处理这个如下：

要解决冲突，我删除了Apache的JAR，我在我的项目。
为了确保所需的库得到正确重新添加，添加此行的build.gradle，在“Android”：
```
useLibrary 'org.apache.http.legacy' 
```

对付一个文件我没有的不同的碰撞需要，我加了本节也正在 “机器人”：

packagingOptions { 
    exclude 'META-INF/maven/oauth.signpost/signpost-core/pom.properties' 
}

然后我的项目建设。
