How to Replace org.apache.http.entity.FileEntity for File Uploads in Android 6 and Above?

Migrating from org.apache.http.entity.FileEntity in Android 6

Upgrading apps to Android 6 introduces conflicts with the deprecated org.apache.http library. The FileEntity class, previously used for uploading files, is no longer supported. Developers seek alternative solutions with simpler implementation.

One approach is to maintain compileSdkVersion at 21, allowing apps to compile using the FileEntity class. However, this workaround does not address the deprecation issue and ignores Google's intentions to transition away from HttpURLConnection.

Therefore, developers are encouraged to explore alternative libraries.

Alternative Libraries for File Uploads

• java.net.HttpUrlConnection: Built-in classic Java HttpURLConnection provides an alternative, albeit with a less user-friendly API.
• Apache's HttpClient for Android: Independent Apache packaging offers a dedicated HttpClient for Android.
• OkHttp (Recommended): Features a user-friendly API for file posting and multipart form uploads.
• AndroidAsync: An asynchronous HTTP and WebSocket client library.

OkHttp Example for File Uploading

OkHttp offers a straightforward API for file uploads:

MultipartBody multipartBody = new MultipartBody.Builder().setType(MultipartBody.FORM)
        .addFormDataPart("image", "filename.png", RequestBody.create(MediaType.parse("image/png"), file))
        .build();

Request request = new Request.Builder().url(server_url).post(multipartBody).build();
