I also tried Shais code from stack oveflow,
Button upload = new Button("Upload");
hi.add(upload);
upload.addActionListener(e -> {
String file = Capture.capturePhoto();
if(file != null) {
try {
String uniqueFileName = "Image" + System.currentTimeMillis() +
".jpg";
MultipartRequest rq = new MultipartRequest();
rq.setUrl("https://s3.amazonaws.com/my-bucket/";);
rq.addArgument("key", uniqueFileName);
rq.addArgument("acl", "private");
rq.addData("file", file, "image/jpeg");
rq.setReadResponseForErrors(true);
NetworkManager.getInstance().addToQueueAndWait(rq);
if(rq.getResponseCode() != 200 && rq.getResponseCode() != 204) {
System.out.println("Error response: " + new
String(rq.getResponseData()));
}
ToastBar.showMessage("Upload completed", FontImage.MATERIAL_INFO);
} catch(IOException err) {
Log.e(err);
}
}});
this gives me the error
