<一个href="http://stackoverflow.com/a/22803149/1226882">http://stackoverflow.com/a/22803149/1226882

这里的code 的

Here's the code

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

产生的原因：java.lang.NoSuchFieldError：无静态字段实例   键入Lorg /阿帕奇/ HTTP /消息/ BasicHeaderValueFormatter;在班上   Lorg /阿帕奇/ HTTP /消息/ BasicHeaderValueFormatter;或其   的超类（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)

我使用的的HttpCore-4.4.1 和 httpmime-4.4.1 的库文件。

推荐答案
