Upload a file from Android to the server via PHP - php

Question

Can anyone help me to make my code work, i.e. upload a file from Android to the server via PHP? I tried it in many different ways but it won't work. I get HTTP Response 200 but the files aren't uploaded on server.
The PHP script I'm using for upload is:
<?php
$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($_FILES['uploaded_file']['name']);
if (move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.\n";
} else {
echo "Possible file upload attack!\n";
}
echo 'Here is some more debugging info:';
print_r($_FILES);
?>
I also tried using multipart from Httpmime 4.0 but it wont work.
public void uploadFile(String path)
{
File file = new File(path);
try {
HttpClient client = new DefaultHttpClient();
String postURL = upLoadServerUri;
HttpPost post = new HttpPost(postURL);
FileBody bin = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("uploaded_file", bin);
post.setEntity(reqEntity);
HttpResponse response = client.execute(post);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
Log.i("RESPONSE Wahaj: ","Code : "+ EntityUtils.toString(resEntity));
}
} catch (Exception e) {
e.printStackTrace();
}
}

public class Helpher extends AsyncTask<String, Void, String> {
Context context;
JSONObject json;
ProgressDialog dialog;
int serverResponseCode = 0;
DataOutputStream dos = null;
FileInputStream fis = null;
BufferedReader br = null;
public Helpher(Context context) {
this.context = context;
}
protected void onPreExecute() {
dialog = ProgressDialog.show(Main2Activity.this, "ProgressDialog", "Wait!");
}
#Override
protected String doInBackground(String... arg0) {
try {
File f = new File(arg0[0]);
URL url = new URL("http://localhost:8888/imageupload.php");
int bytesRead;
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + BOUNDARY);
String contentDisposition = "Content-Disposition: form-data; name=\"keyValueForFile\"; filename=\""
+ f.getName() + "\"";
String contentType = "Content-Type: application/octet-stream";
dos = new DataOutputStream(conn.getOutputStream());
fis = new FileInputStream(f);
dos.writeBytes(SPACER + BOUNDARY + NEW_LINE);

dos.write(buffer, 0, bytesRead);
}
dos.writeBytes(NEW_LINE);
dos.writeBytes(SPACER + BOUNDARY + SPACER);
dos.flush();
int responseCode = conn.getResponseCode();
if (responseCode != 200) {
Log.w(TAG,
responseCode + " Error: " + conn.getResponseMessage());
return null;
}
br = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
Log.d(TAG, "Sucessfully uploaded " + f.getName());
} catch (MalformedURLException e) {
} catch (IOException e) {
} finally {
try {
dos.close();
if (fis != null)
fis.close();
if (br != null)
br.close();

}
return String.valueOf(serverResponseCode);
}
#Override
protected void onPostExecute(String result) {
dialog.dismiss();
}
}
This is the AsyncTask "Helpher" class used for upload image from Android. To call this class use like syntax below.
new Main2Activity.Helpher(this).execute(fileUri.getPath());
Here fileUri.getPath() local image location.
