They sort of work, but the load and progress events won’t fire. Amazon S3 stores these parts, but it creates the object from the parts only after you upload all of them and send a successful request to complete the multipart upload (you should verify that your request to complete multipart upload is successful). Android inconsistencies But there’s still one problem: some Android devices don’t play entirely well with this technique. After you initiate a multipart upload, you begin uploading parts.

Our ServletContextListener implementation code is like below. The beauty of this example is: if the object detection script returns false, this form will still work, and therefore functionality will remain intact. We can set absolute directory location and File object as context attribute to be used by other servlets. Next, we create an HTTP Request using the RequestBuilder and. When we created the builder, we add a binary body containing the file that’ll be uploaded and also a text body. Assuming the server is expecting a POST request with the content, heres a simple example of how to complete this task in Android. We create an HttpEntity using the MultipartEntityBuilder. Quite often its necessary to send/upload a file to a remote server, for example, an image, video, audio or a backup of the application database to a remote private server.

Since we need to read context parameter for file location and create a File object from it, we can write a ServletContextListener to do it when context is initialized. In this example we’ll show how to to a multipart file upload using HttpClient 4.5.

This is my way of doing it.ServletContextListener for File Upload Location This is sample implementation of 'com.bikomobile:multipart' library, which allows the to pick multiple files from android device and upload it into the server - GitHub - kariot/Android-Multipart-File-Uploading: This is sample implementation of 'com.
