    copied!<p>I am trying to use the following code to upload a file to a rest api. This code works fine for files up to around 20MB, but bigger files will give an <code>OutOfMemoryError</code>. I am trying to chunk the request and use a multipart-form request so that I don't have to keep the whole file in memory, but maybe the chunks are too big? Any help is greatly appreciated.</p> <pre><code> final File file = new File(filePath); HttpHeaders header = new HttpHeaders(); header.add("x-haiku-auth", HaikuAPI.getAuthHeader()); header.setContentType(MediaType.MULTIPART_FORM_DATA); UriComponentsBuilder builder = UriComponentsBuilder.fromUriString( "https://" + HaikuAPI.getDomain() + "/api/assignments") .pathSegment(assignmentID + "", "submit"); URI url = builder.build().toUri(); MultiValueMap&lt;String, Object&gt; parts = new LinkedMultiValueMap&lt;String, Object&gt;(); parts.add("message[subject]", "Assignment Completed"); parts.add("message[body]", message); parts.add("message[assignment_id]", assignmentID + ""); Uri uri = Uri.fromFile(file); InputStreamResource res = new InputStreamResource(context.getContentResolver().openInputStream(uri)) { @Override public String getFilename() throws IllegalStateException { return file.getName(); } @Override public long contentLength() throws IOException { return file.length(); } }; parts.add("files[][file]", res); parts.add("files[][filename]", file.getName()); SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory(); factory.setChunkSize(1024); RestTemplate restTemplate = new RestTemplate(factory); restTemplate.getMessageConverters().add(new FormHttpMessageConverter()); HttpEntity&lt;Object&gt; request = new HttpEntity&lt;Object&gt;(parts, header); restTemplate.postForLocation(url, request); Log.e("f", "finished"); return null; </code></pre> <p>Error: <code>dalvikvm-heap: Out of memory on a 67102090-byte allocation.</code></p>
