Entity returns error in MultiPartEntityBuilder

问题

I've tried following links but none of them helped to solve the issue.

HttpPost returning error when using MultipartEntityBuilder in Android

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

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()));

Error

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)

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

回答1:

Finally I've solved it.

It's a library issue, it worked with 4.3.1 version.

Here's the link to download library files

回答2:

Try with theese versions, is working for me

compile 'org.apache.httpcomponents:httpcore:4.3.3'
compile('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude module: 'httpclient'
}

Also you can read more here.

回答3:

multipartBuilder.addPart("images[]", fileBody); fileBody convert into byteArray then you pass because data travel in byte array

Try to upload the image in php server but it could post. in android
