In above code,converted base 64 string as value not passing in request. i am stuck in this task,help me out guys
Use this
library for multipart requests, i-e image, video or any other data for POST request
Is anybody aware of an Android app that acts as a REST API client and allows attaching files? I'm looking to do the equivalent of this in Postman, but from an Android device:
I've tried "REST Client for Android" and "HTTP Client" available on Google Play, but these only seem to allow text in the body, not file attachments. Can anybody advise on options for this for Android currently ??

It is working fine.but empty file is created in server.
If any one know the solution ,please help me .
Thanks in advance.
Try this code. It is using a class "SimpleMultipartEntity" using which you can easily send the file.
I'd prefer using Apache Http commons, it is part of android. I think this is a much simpler and cleaner approach. You need to do something like this:
AndroidHttpClient client = AndroidHttpClient.newInstance("useragent string");
URI uri = "something";
File file = new File("/tmp/data");
HttpPost post = new HttpPost(uri);
post.setEntity(new FileEntity(file, "text/html"));
HttpResponse httpResponse = client.execute(post);
int statusCode = httpResponse.getStatusLine().getStatusCode();
I need to upload a file from my android emulator directory ('data\data\org.mypackage\file.dat') to a remote server, but when I try to access the file it gives an error like 'error: Permission denied', I store my sqlite database in 'data\data\org.mypackage\databases\' folder , during the application startup if there is no sqlite db in that folder I copied it from my asset folder to that directory and access it from there it works perfect but in the case upload task it ask for permission why this occur? following is my uploadFile method
