Android Httpclient [NoSuchMethodError:org.apache.http.entity.ContentType.create]

Question

我想将图像从 android 上传到 spring 控制器。 我已经使用rest api调用（httpclient）将android与spring连接了 我的代码是：

final String jsonUserMo = gson.toJson(userMO);
    final StringBuilder contactLists = new StringBuilder();
    HttpClient client = new DefaultHttpClient();
    HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
    try {
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        FileBody profileFile = new FileBody(profileImage);
        builder.addPart("uploadImg", profileFile);
        HttpEntity entity = builder.build();
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("userMO", jsonUserMo));
        HttpPost post = new HttpPost(Constants.ROOTURL+"/media/uploadUserImage");
        post.setEntity(entity);
        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        Log.i("Ringee",post.toString());
        HttpResponse response = client.execute(post);
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        contactLists.append(rd.readLine());
    } catch (Exception e) {
        e.printStackTrace();
    }

个人资料图片是文件。 并使用多方上传 但是我在android中遇到了错误

Caused by: java.lang.NoSuchMethodError: org.apache.http.entity.ContentType.create

我的安卓依赖：

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar'])
   compile 'com.android.support:appcompat-v7:21.0.3'
   compile 'com.google.android.gms:play-services:6.1.11'
   compile ('org.apache.httpcomponents:httpmime:4.4.1') {
      exclude module: 'httpclient'
   }
   compile 'org.apache.httpcomponents:httpclient-android:4.3.5'
}

错误：

Answer 1

看起来您为 httpmime 和 httpclient-android 使用了不兼容的 jar。尝试使用httpmime的版本4.3.6

Answer 2

我也和你一样，然后我刚刚使用了相同的库版本并且它工作了，

我不知道如何，但下面的代码解决了我的问题

compile( 'org.apache.httpcomponents:httpmime:4.3.5') {
    exclude module: 'httpclient'
}
compile 'org.apache.httpcomponents:httpclient-android:4.3.5'

Answer 3

NoSuchMethodError

如果应用程序尝试调用类的指定方法时抛出 （静态或实例），并且该类不再有定义 那个方法。通常，这个错误会被编译器捕获；这 如果类的定义有，则错误只会在运行时发生 不兼容的更改。

您应该使用两者的不兼容版本。

 compile ('org.apache.httpcomponents:httpmime:4.5.2') {
      exclude module: 'httpclient'
   }
   compile 'org.apache.httpcomponents:httpclient:4.5'
