据我所知,https://github.com/google/volley/wiki/Migrating-from-Apache-HTTP volley 1.1删除了对org.apache.http的强制依赖.和
“Most apps using HurlStack or Volley#newRequestQueue with
minSdkVersion set to 9 or higher should not need to take any action
other than removing the useLibrary ‘org.apache.http.legacy’ declaration from your build.gradle file if it is present.”
我没有在任何地方使用org.apache.http,但是当我尝试在单元测试中执行Volley.newRequestQueue(context.getApplicationContext())或新的HurlStack()时,我得到:
java.lang.NoClassDefFoundError: org/apache/http/StatusLine
在运行时.检查HurlStack类我看到它继承自BaseHttpStack,它显然仍然依赖于org.apache.http
import org.apache.http.ProtocolVersion; import org.apache.http.StatusLine; import org.apache.http.entity.BasicHttpEntity; import org.apache.http.message.BasicHeader; import org.apache.http.message.BasicHttpResponse; import org.apache.http.message.BasicStatusLine;
所以,我没有得到它,我是否应该包括org.apache.http如果使用带有api级别的凌空> 23或不?
解决方法:
如果我将它包含在build.gradle中,测试运行正常:
testImplementation "org.apache.httpcomponents:httpclient:4.5.5"
注意:
这不是关于NoClassDefFoundError的一般性问题,它特别关注Volley在指令(阅读帖子上的链接)说不应该抛出此异常时抛出此异常.
