参见英文答案 > Getting NoSuchFieldError INSTANCE org/apache/http/message/BasicHeaderValueParser                                    4个
解决方案如下

我正在使用凌空库上传图片.条件是我要求发送

> key1 =字符串值
> key2 =字符串值
> key3 {= file} =图像值,即jpeg,jpg

这是我正在使用的代码(评论部分是我已经尝试过的) –

请帮帮我.先感谢您！！

解

虽然标记为重复,但我没有在那里找到任何解决方案.我终于揭开了我所遗忘的一切.我重读了androID上的文档,我可以在这里找到它 – http://developer.android.com/preview/behavior-changes.html#behavior-apache-http-client

所以我已经删除了所有那些httpcomponents,其中包括httpcore,httpmime,httpclIEnt等.现在不知道哪些垃圾堆栈的东西都被建议堆栈溢出,所有这些都是正确的,直到昨天但不是M预览.而不是那个添加

androID {   uselibrary 'org.apache.http.legacy'}

之前使用过的请求类更改如下 –

最后得到了正确的响应.我希望这能帮助那些和我一样陷入困境的人. 总结
