包括Android Gradle项目中的Apache HttpComponents在内的问题

我尝试在我的应用程序中使用build.gradle文件包含httpmime，并且所有的编译都很好。相反，当应用程序尝试实际使用MultipartEntityBuilder类时，日志中会有一堆警告级别的消息，说明存在问题。包括Android Gradle项目中的Apache HttpComponents在内的问题

下面是从我的build.gradle的依赖性的摘录：

 
    compile('org.apache.httpcomponents:httpmime:4.+') { 
     exclude module: "httpclient" 
    }

下面是错误：

的Java类：

 
import android.util.Log; 

import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 
import java.net.HttpURLConnection; 
import java.net.URL; 

import org.apache.http.HttpEntity; 
import org.apache.http.entity.mime.MultipartEntityBuilder; 

public class FileUploader { 
    private final static String BOUNDARY = "__--__--__SERVETHEOVERMIND-__-_"; 

    public void uploadFile(String targetUrl, MultipartEntityBuilder upload, UploadHandler after) { 
     Log.v("FileUploader", "Uploading to " + targetUrl); 

     HttpURLConnection con = null; 
     OutputStream os = null; 
     InputStream is = null; 

     try { 
      HttpEntity uploadEntity = upload.build(); 
      URL postTo = new URL(targetUrl); 
      con = (HttpURLConnection) postTo.openConnection(); 

      con.setRequestMethod("POST"); 
      con.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + BOUNDARY); 
      con.setDoOutput(true); 
      con.setDoInput(true); 
      con.setUseCaches(false); 

      con.addRequestProperty("Connection", "Keep-Alive"); 
      con.setRequestProperty("Content-length", String.valueOf(uploadEntity.getContentLength())); 

      os = con.getOutputStream(); 
      uploadEntity.writeTo(os); 
      os.close(); 

      con.connect(); 
      is = con.getInputStream(); 

      after.consumeUploadResponse(is); 
      con.disconnect(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     if(con != null) { 
      con.disconnect(); 
     } 

     if(os != null) { 
      try { 
       os.close(); 
      } catch (IOException e) { 
       Log.v("Uploader", "Closed output stream"); 
      } 
     } 

     if(is != null) { 
      try { 
       is.close(); 
      } catch (IOException e) { 
       Log.v("Uploader", "Closed input stream"); 
      } 
     } 
    } 

    public interface UploadHandler { 
     public void consumeUploadResponse(InputStream stream); 
    } 
}

[编辑]正确的依赖关系，根据回答

 
compile('org.apache.httpcomponents:httpmime:4.+') { 
    exclude module: "httpclient" 
} 
compile('org.apache.httpcomponents:httpcore:4.+') { 
    exclude module: "httpclient" 
}

[第二编辑]问题仍然没有解决 - 现在它的这些失位，但它可能是在后端问题：

 
10-10 11:51:54.998 29597-29638/com.company.app W/dalvikvm﹕ VFY: unable to resolve static field 7465 (INSTANCE) in Lorg/apache/http/message/BasicHeaderValueParser; 
10-10 11:51:54.998 29597-29638/com.company.app W/dalvikvm﹕ VFY: unable to resolve static field 7459 (INSTANCE) in Lorg/apache/http/message/BasicHeaderValueFormatter;

[又一编辑]

在这种情况下，似乎最后一点遗漏的位对成功使用MultipartEntityBuilder没有任何影响。

您是否设法删除了Lorg/apache/http/message ....静态字段警告？我似乎现在有类似的问题。 –

上面的第一个代码块修复了我在android studio中收到的警告。谢谢！ – Josh

您需要将httpcore-4.3.jar添加到您的java构建路径。我遇到了同样的问题，添加了这个jar之后就消失了。

我以为是的，但我仍然陷在类似的问题 –

它看起来像它可能工作，尽管最新的错误信息 - 现在我正在看轨道后端 –

如果你是新的Android Studio和现在确定如何将jar添加到你的构建路径中，看到类似问题的答案：http://stackoverflow.com/a/28712564 - 你只需要从'httpcore'而不是'httpmime'进行搜索。 –

这是我在gradle这个是怎么做..

dependencies { 
compile ('org.apache.httpcomponents:httpmime:4.3'){ 
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' 
} 
compile ('org.apache.httpcomponents:httpcore:4.4.1'){ 
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' 

} 
}

而且里面的Android

android{ 
packagingOptions { 
    exclude 'META-INF/DEPENDENCIES' 
    exclude 'META-INF/NOTICE' 
    exclude 'META-INF/LICENSE' 
} 
}

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1' compile('org.apache.httpcomponents:httpmime:4.3') { 
    exclude module: "httpclient" }

您可以使用此以上依赖于的build.gradle（模块：应用）到您的项目以下IMPORT语句

import org.apache.http.entity.ContentType; import org.apache.http.entity.mime.MIME;
