Android - MultipartEntity and dependencies

Question

I recently migrate my project from Eclipse to Android Studio (I do not fully control this IDE yet). In this project, I have a file uploader AsyncTask which send multipart over http. To do this, I use org.apache.httpcomponents. I created following dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.apache.httpcomponents:httpcore:4.4'
    compile 'org.apache.httpcomponents:httpmime:4.4'
    ...
}

In my java AsyncTask code:

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addBinaryBody(...);
builder.addBinaryBody(...);
builder.addBinaryBody(...);
HttpEntity entity = builder.build(); // < throw exception

---

The exception I obtain at startup upload:

Caused by: java.lang.NoSuchFieldError: org.apache.http.message.BasicHeaderValueFormatter.INSTANCE
    at org.apache.http.entity.ContentType.toString(ContentType.java:153)
    at org.apache.http.entity.mime.MultipartFormEntity.<init>(MultipartFormEntity.java:52)
    at org.apache.http.entity.mime.MultipartEntityBuilder.buildEntity(MultipartEntityBuilder.java:226)
    at org.apache.http.entity.mime.MultipartEntityBuilder.build(MultipartEntityBuilder.java:230)

I think there is a conflict between android.jar > httpcomponents and the org.apache.httpcomponents dependency but I don't find a solution to resolve my problem.

I had the same issue - try to use the http-android-client (this also relies on the httmime but requires 4.3). This worked for me:

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