How to Send Multipart Requests with Volley After HttpEntity Deprecation?

Multipart Request with Volley Without HttpEntity

Introduction

With HttpEntity deprecated in API22 and removed in API23, Android developers may face challenges when sending multipart requests using Volley. This article provides a working code sample for POST multipart requests with Volley without the use of HttpEntity.

Code Implementation

MultipartActivity.java:

package com.example.multipartvolley;

// ... As before

@Override
protected void onCreate(Bundle savedInstanceState) {
    // ... As before

    byte[] fileData1 = getFileDataFromDrawable(context, R.drawable.ic_action_android);
    byte[] fileData2 = getFileDataFromDrawable(context, R.drawable.ic_action_book);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(bos);

    try {
        // ... As before
    } catch (IOException e) {
        // ... As before
    }

    String url = "http://192.168.1.100/api/postfile";
    MultipartRequest multipartRequest = new MultipartRequest(url, null, mimeType, multipartBody, new Response.Listener<NetworkResponse>() {
        @Override
        public void onResponse(NetworkResponse response) {
            // ... As before
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // ... As before
        }
    });

    // ... As before
}

// ... Remaining methods

MultipartRequest.java:

package com.example.multipartvolley;

// ... As before

@Override
public String getBodyContentType() {
    return mMimeType;
}

@Override
public byte[] getBody() throws AuthFailureError {
    return mMultipartBody;
}

// ... Remaining methods

Updated with Text Data

To include text data in the request, you can override the getParams() method in VolleyMultipartRequest:

@Override
protected Map<String, String> getParams() {
    Map<String, String> params = new HashMap<>();

    // Add your text parameters
    params.put("api_token", "gh659gjhvdyudo973823tt9gvjf7i6ric75r76");
    params.put("name", "Angga");
    params.put("location", "Indonesia");

    return params;
}

Conclusion

The provided code provides a practical solution for sending multipart requests with Volley, even after the deprecation of HttpEntity. By using the methods described in this article, developers can easily POST multiple files and text data to a server without the need for complex HttpEntity implementations.
