Android Uploading a file to php

i want to upload a file to server php using post
Heres my code
String url = "http://blabla.com/upload.php";
File file = new File(Environment.getExternalStorageDirectory(),
"Myfile.log");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(
new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
//Do something with response...
}
My question is how can i handle it on php ? If its in $_FILES array then what id i should use to put it in uploads folder ($_FILES['whatShouldBeHere'] )? Thanks .

Servlet request.getParameter() always return null value

I'm working on simple client server communication using HttpPost. From the client side I'm setting a parameter(filename).
At the server side when I try to get the parameter value it's always showing null. I tried using MultiPartEntity but even that is not working.
Below is my client code:
HttpPost httppost = new HttpPost("http://xxx.xxx.xxx.xxx:yyyy");
InputStreamEntity reqEntity = new InputStreamEntity(
new FileInputStream(dataFile), -1);
reqEntity.setContentType("binary/octet-stream");
// Send in multiple parts if needed
reqEntity.setChunked(true);
httppost.setEntity(reqEntity);
//setting the parameter
httppost.getParams().setParameter("filename", "xxxx.xml");
HttpResponse response = httpclient.execute(httppost);
int respcode = response.getStatusLine().getStatusCode();
And this is my servlet code:
response.setContentType("binary/octet-stream");
Scanner scanner = new Scanner(request.getInputStream());
// reading the parameter
String filename = request.getParameter("filename");
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(new File("C:\\" + filename)));
Kindly let me know any possible solution for this issue.
Thanks in advance!

Ur setting parameters wrong... at the client side, do this:
ArrayList<NameValuePair> postParameters = postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("filename", "xxxx.xml");
httppost.setEntity(new UrlEncodedFormEntity(postParameters));
HttpResponse response = httpclient.execute(httppost);

MultipartEntity and Json

I want to send an image and a JsonObject to an PHP Server with MultipartEntity.
Here is my Code:
HttpClient httpClient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(urlString);
File file = new File(imageend);
HttpResponse response = null;
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
StringBody sb;
try {
sb = new StringBody(json.toString());
mpEntity.addPart("foto", cbFile);
mpEntity.addPart("json", sb);
httppost.setEntity(mpEntity);
response = httpClient.execute(httppost);
I can't read this in php because the format is like:
{\"test1\":\"Z\",\"test2\":\"1\"}
I'm not able to read this in php because of the backslashes. If I post json without image over httppost and bytearrayentity there aren't any backslashes and I have no problem.

Use following PHP:
string stripslashes ( string $str )

Maybe you can just replace the \" by \ using preg_replace on the PHP side

cURL command using java

curl -F file=#/path/to/index.html -u lslkdfmkls#gmail.com -F 'data={"title":"API V1 App","package":"com.alunny.apiv1","version":"0.1.0","create_method":"file"}' https://build.phonegap.com/api/v1/apps
I am trying to achieve the same using a java program using HttpClient library.
DefaultHttpClient client = new DefaultHttpClient();
HttpHost targetHost = new HttpHost("build.phonegap.com", 443, "https");
client.getCredentialsProvider().setCredentials(
new AuthScope(targetHost.getHostName(), targetHost.getPort(),AuthScope.ANY_REALM),
new UsernamePasswordCredentials("abc#gmail.com", "abc123"));
String authToken = "?auth_token=abcdefgh";
HttpPost httpPost = new HttpPost("https://build.phonegap.com/api/v1/apps" + authToken );
String jsonString = "{\"title\":\"API V1 App\",\"create_method\":\"file\"}";
MultipartEntity multipartEntity = new MultipartEntity();
multipartEntity.addPart(new FormBodyPart("data", new StringBody(jsonString)));
multipartEntity.addPart("file", new FileBody(new File("C:/Users/Desktop/app.zip")));
/*StringEntity entity = new StringEntity(jsonString, "UTF-8"); */
httpPost.setEntity(multipartEntity);
System.out.println("executing request " + httpPost.getRequestLine());
HttpResponse httpResponse = client.execute(httpPost);
HttpEntity entity = httpResponse.getEntity();
System.out.println(httpResponse.getStatusLine());
if(entity != null ){
System.out.println(EntityUtils.toString(entity));
}
In the above code I can only set StringEntity or FileEntity but not both and I think this is what is required to get the functionality of the curl command.
After trying with StringEntity and FileEntity I tried with MultipartEntity but no luck..
Can you please provide me with more details and if possible an example..
Thanks in advance.

One has to instantiate the MultipartEntity as follows:
MultipartEntity multipartEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE
) ;
This worked for me.
By default the MultipartEntity is instantiated with HttpMultipartMode.STRICT mode which is documented in the javadocs as "RFC 822, RFC 2045, RFC 2046 compliant" .
Can someone brief out the RFC's mentioned here for clear understanding..
Thanks a Lot

Post text and files in Java/Android in UTF-8

I have the following code for posting a text and a file with http:
HttpPost post = new HttpPost(url);
MultipartEntity entity = new MultipartEntity();
entity.addPart("field_1", new StringBody(textField));
entity.addPart("field_2", new FileBody(new File(filepath)));
post.setEntity(entity);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(post);
It works nice the problem is that I need the textField value to be encoded in UTF-8.Any ideas?
Editted: Found an error in the code, posting the working answer

The sollution is to use:
new StringBody(textField,"text/plain",Charset.forName("UTF-8")
