I hope it will work
// the file to be posted
String textFile = Environment.getExternalStorageDirectory() + "/sample.txt";
Log.v(TAG, "textFile: " + textFile);
// the URL where the file will be posted
String postReceiverUrl = "http://yourdomain.com/post_data_receiver.php";
Log.v(TAG, "postURL: " + postReceiverUrl);
// new HttpClient
HttpClient httpClient = new DefaultHttpClient();
// post header
HttpPost httpPost = new HttpPost(postReceiverUrl);
File file = new File(textFile);
FileBody fileBody = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file", fileBody);
httpPost.setEntity(reqEntity);
// execute HTTP post request
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseStr = EntityUtils.toString(resEntity).trim();
Log.v(TAG, "Response: " + responseStr);
// you can add an if statement here and do other actions based on the response
}
and php code.
<?php
// if text data was posted
if($_POST){
print_r($_POST);
}
// if a file was posted
else if($_FILES){
$file = $_FILES['file'];
$fileContents = file_get_contents($file["tmp_name"]);
print_r($fileContents);
}
?>
