在Android中使用MultipartEntityBuilder时HttpPost返回错误

https://stackoverflow.com/a/22803149/1226882

这是代码

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(Utility.AddProductWS);

MultipartEntityBuilder multipartBuilder = MultipartEntityBuilder.create();

/* example for setting a HttpMultipartMode */
multipartBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

for (int i = 0; i < photos.size(); i++) {

    multipartBuilder.addBinaryBody("images[]", newFile(photos.get(i).getImagePath());
}

multipartBuilder.addTextBody("username", username.toString());
multipartBuilder.addTextBody("accept_best_offer", String.valueOf(acceptOffer.isChecked() ? 1 : 0));
multipartBuilder.addTextBody("accept_trade", String.valueOf(acceptTrade.isChecked() ? 1 : 0));
multipartBuilder.addTextBody("product_price", etProductPrice.getText().toString());
multipartBuilder.addTextBody("product_description", etProductDescription.getText().toString());

HttpEntity httpEntity = multipartBuilder.build();
httpPost.setEntity(httpEntity);  // Error line
HttpResponse response = httpClient.execute(httpPost);
Utility.showLog(TAG, EntityUtils.toString(response.getEntity()));

错误

Caused by: java.lang.NoSuchFieldError: No static field INSTANCE of输入 Lorg/apache/http/message/BasicHeaderValueFormatter;在班上Lorg/apache/http/message/BasicHeaderValueFormatter;或其超类(声明'org.apache.http.message.BasicHeaderValueFormatter' 出现在/system/framework/ext.jar)

Caused by: java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/message/BasicHeaderValueFormatter; in class Lorg/apache/http/message/BasicHeaderValueFormatter; or its superclasses (declaration of 'org.apache.http.message.BasicHeaderValueFormatter' appears in /system/framework/ext.jar)

我正在使用 httpcore-4.4.1 和 httpmime-4.4.1 库文件.

I am using httpcore-4.4.1 and httpmime-4.4.1 library files.

推荐答案

我终于解决了.

这是一个库问题，它适用于 4.3.1 版本.

这是下载库文件的链接
