I am trying to download a file from a php get url that has username and password. My code doesn't show any errors and the progress bar shows me that the file is downloaded but when I try to print the list inside the Log I cannot see the file. What am I doing wrong?
That's the code inside the doInBackground section in the AsyncTask which I have called inside the onCreate and have put the url inside the parameters.
protected String doInBackground(String... sUrl) {
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
try{
URL url = new URL(sUrl[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
int fileLength = connection.getContentLength();
input = connection.getInputStream();
output = new FileOutputStream(context.getFilesDir()+"video.m3u");
byte data[] = new byte[4096];
long total = 0;
int count;
while ((count = input.read(data)) != -1){
total = total + count;
if (fileLength > 0){
publishProgress((int) (total * 100 / fileLength));
}
output.write(data, 0, count);
}
}catch (Exception e){
return e.toString();
}finally {
try{
if (output != null){
output.close();
}
if (input != null){
input.close();
}
}catch (IOException ignored){
}
if (connection != null){
connection.disconnect();
}
}
return "";
}
In the onPostExecute section I have written this code
if (result.equals("")){
String path = context.getFilesDir().toString();
Log.d("Files", "Path: "+ path);
File directory = new File(path);
File[] files = directory.listFiles();
Log.d("Files", "Size: " + files.length);
for (int i = 0; i<files.length; i++){
Log.d("Files", "File Name: " + files[i].getName());
}
}
But the only thing that I get printed is this:
D/Files: Path: /data/data/my.app.package/files
D/Files: Size: 1
D/Files: File Name: instant-run
I can't see the file that has been downloaded.
I think the problem is this line
output = new FileOutputStream(context.getFilesDir()+"video.m3u");
context.getFilesDir() doesn't return String, it's File object you need to do this
output = new FileOutputStream(context.getFilesDir()..getAbsolutePath()+"/video.m3u");
The file path you are saving to is wrong. Right now you are saving to
output = new FileOutputStream(context.getFilesDir()+"video.m3u");
it needs to be output = new FileOutputStream(context.getFilesDir().getAbsolutePath()+"/video.m3u");
Hopes this helps.

I have build a server use PHP based on WAMP Server on my windows 10 computer. what I want to do is when I send a GET request, the show_files.php should return a JSON object to me. The JSON object contains file names in path F:\NetEaseMusic\download on my computer. Then I use a file name to send a POST request to download_file.php and it returns a data stream so that I can download file. When I use HttpURLConnection, everything works well. However, when I try send the POST request use socket, download_file.php can get the file_name param, but it can not find the target file in F:\NetEaseMusic\download. I show the code.
this is
this is download_file.php
<?php
if(empty($_POST["file_name"]))
{
echo "NO_FILE_NAME\n";
print_r($_POST);
exit();
}
$path = iconv("utf-8", "GB2312","F:\\NetEaseMusic\\download\\".$_POST["file_name"]);
//$path = "F:\\NetEaseMusic\\download\\".$_POST["file_name"];
if (!file_exists ( $path )) {
echo "FILE_NOT_FOUND\n";
echo "F:\\NetEaseMusic\\download\\".$_POST["file_name"]."\n";
print($path);
exit ();
}
$file_size = filesize($path);
//header("Content-type: application/octet-stream");
//header("Accept-Ranges: bytes");
//header("Accept-Length:".$file_size);
//header("Content-Disposition: attachment; filename=".$path);
$file = fopen($path, "r");
while(!feof($file))
{
echo fread($file, 1024);
}
exit();
?>
this is my Client code which to download file. First of all I build a HTTP POST request,
private void downloadFileBySocket(String urlString, String fileName)
{
try{
StringBuilder sb = new StringBuilder();
String data = URLEncoder.encode("file_name", "utf-8") + "=" + URLEncoder.encode(fileName, "utf-8") + "\r\n";
//String data = "&file_name="+fileName;
sb.append("POST " + urlString + " HTTP/1.1\r\n");
sb.append("Host: 10.206.68.242\r\n");
sb.append("Content-Type: application/x-www-form-urlencoded\r\n");
sb.append("Content-Length: " + data.length() + "\r\n");
sb.append("\r\n");
sb.append(data + "\r\n");
//sb.append( URLEncoder.encode("file_name", "utf-8") + "=" + URLEncoder.encode(fileName, "utf-8") + "\r\n");
System.out.println(sb.toString());
URL url = new URL(urlString);
Socket socket = new Socket(url.getHost(), url.getPort());
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "utf-8"));
writer.write(sb.toString());
writer.flush();
File file = new File("./" + fileName);
DataOutputStream out = null;
DataInputStream in = null;
try{
out = new DataOutputStream(new FileOutputStream(file));
in = new DataInputStream(socket.getInputStream());
byte[] buffer = new byte[1024];
int readBytes = 0;
while((readBytes = in.read(buffer)) != -1)
{
out.write(buffer, 0, readBytes);
}
out.flush();
}catch (Exception e1)
{
e1.printStackTrace();
}finally {
try{
if(in != null)
{
in.close();
}
if(out != null)
{
out.close();
}
}catch (Exception e2)
{
e2.printStackTrace();
}
}
socket.close();
}catch (Exception e)
{
e.printStackTrace();
}
}
and my main[] method
public static void main(String[] args)
{
SocketTest socketTest = new SocketTest();
socketTest.downloadFileBySocket(SocketTest.downloadFileUrl, "小胡仙儿 - 【二胡】霜雪千年.mp3");
}
Simple way:
using System.Net;
WebClient webClient = new WebClient();
webClient.DownloadFile("example.com/myfile.txt", #"c:/myfile.txt");

And the bellow is my code in PHP:
$target = "/upload/";
$target = $target . basename( $_FILES['fileToUpload']['name']) ;
if(move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $target)) {
echo "The file ". basename( $_FILES['fileToUpload']['name']). " has been uploaded";
$result['login'] = true;
}else {
$result['login']=false;
echo "Sorry, there was a problem uploading your file.";
}
$json = json_encode($result, JSON_PRETTY_PRINT);
print_r($json);
Maybe problem occur when you set Content-Type, try remove this
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+BOUNDRY);
I'm trying to encode a .jpg file on my server and send the string back to my android app. The PHP encoding function doesn't seem to be working - I always get a null response.
...
} else if ($tag == 'getPhoto') {
$filePath = $_POST['filePath'];
$filePath = mysql_real_escape_string($filePath);
$photo_str = $db->getPhotoString($filePath);
$photo_str = mysql_real_escape_string($photo_str);
if (!empty($photo_str)) {
echo $photo_str;
} else {
echo 'Something went wrong while retrieving the photo.';
}
}
...
public function getPhotoString($filePath) {
$type = pathinfo($filePath, PATHINFO_EXTENSION);
$photoData = file_get_contents($filePath);
$photo_str = 'data:image/' . $type . ';base64,' . base64_encode($photoData);
// $photo_str = 'test_response';
return $photo_str;
}
I know my filepath is correct because when I change it I get an error that says the file/directory doesn't exist. And, the "test_response" works when I uncomment it. Please help!
UPDATE - relevant android code:
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(parameters));
HttpResponse response = httpClient.execute(httpPost);
photoString = convertResponseToString(response);
Log.d("string response", photoString);
public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{
String res = "";
StringBuffer buffer = new StringBuffer();
is = response.getEntity().getContent();
int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
if (contentLength < 0) {
} else {
byte[] data = new byte[512];
int len = 0;
try {
while (-1 != (len = is.read(data))) {
buffer.append(new String(data, 0, len)); //converting to string and appending to stringbuffer…..
}
} catch (IOException e) {
e.printStackTrace();
}
try {
is.close(); // closing the stream…..
} catch (IOException e) {
e.printStackTrace();
}
res = buffer.toString(); // converting stringbuffer to string…..
}
//System.out.println("Response => " + EntityUtils.toString(response.getEntity()));
return res;
}
This is not an answer, only a suggestion but i'm not able to comment as i don't have enough reputation xD. Anyway, did you try to echo $photoData after
$photoData = file_get_contents($filePath);
to see if it's filled with something? Maybe you get a null result. Also, can you tell me what's $filePath value when taken from $_POST variable and when passed to getPhotoString($filePath) function? I'm thinking about something wrong with mysql_real_escape_string().
I am developing an Android app that should get an image from remote server. Am using WAMP as my server and PHP as programming language. I know how to get text data using JSON.
Am not using blob to store image.
Images have stored in a folder on server. Url of image is stored in db table.
I tried the following snippet, I got this from net but it is not giving any error and also it is not displaying image
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://10.0.2.2/sareesProject/returnSareeTypeImageUrls.php");
response = httpClient.execute(httpPost);
entity = response.getEntity();
if(response.getStatusLine().getStatusCode() == 200)
{
Log.d("Http Response:", response.toString());
if(entity != null)
{
InputStream instream = entity.getContent();
JSONObject jsonObj = new JSONObject(convertStreamToString(instream));
String base64Image = jsonObj.getString("pprs");
Toast.makeText(getBaseContext(), base64Image, Toast.LENGTH_LONG).show();
byte[] rawImage = Base64.decode(base64Image, Base64.DEFAULT);
bmp = BitmapFactory.decodeByteArray(rawImage, 0, rawImage.length);
}
}
ImageView imageview = (ImageView) findViewById(R.id.flag);
imageview.setImageBitmap(bmp);
The following is my php code
<?php
error_reporting( E_ALL ^ E_NOTICE ^ E_WARNING);
$con = mysql_connect("localhost","root","") or die("con error");
mysql_select_db("sareesdb") or die("db select eror");
$query = mysql_query("select * from noofpiecesinatype");
if($row = mysql_fetch_assoc($query))
{
$response = $row['imageUrl'];
}
$response = base64_encode($response);
echo '{"pprs":'.json_encode($response).'}';
mysqli_close($con);
?>
I checked my php code with html(with out encoding $response value) am getting image there, but not in Android.
I am not good with Php, but if you return the file url via a JSON reponse you can use the following code for downloading the file.
int count;
try {
URL url = new URL("http://url of your file");
URLConnection conection = url.openConnection();
conection.connect();
// getting file length
int lenghtOfFile = conection.getContentLength();
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
OutputStream output = new FileOutputStream("/sdcard/downloadedfile.jpg");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress(""+(int)((total*100)/lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
} catch (Exception e) {
Log.e("Error: ", e.getMessage());
}
## Edit ##
After the Image is downloaded you can create a Bitmap from the Image Path/InputStream and assign it to the Image View like this
BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
Bitmap bmp = BitmapFactory.decodeStream(bufferedInputStream);

Fnally i got it.............
First of all my server file returns the following
{"pprs":"upload/22.png"}
from this i extracted upload/22.png using JSON
Now bitmapPath contains upload/22.png
Thank you very much to insomniac giving suggestions.............
If it is helpful to any one vote for me..............
I have written Android code to upload a large file (10MB+) via HTTP Put to an Apache PHP server (I cannot use FTP because my application sometimes operates on mobile networks, and I hear many mobile carriers do not allow FTP-If I am wrong, please correct me). The function that handles the actual upload is called by an AsyncTask, so it does not cause the application to hang. However, I have some concerns about the method of uploading-sometimes I get incomplete uploads, sometimes with "false positives"-I get a signal back that the file uploaded, only to check and see nothing.
My background is deeper in C than Java and I'm not entirely clear about Java's automatic memory management, so if my questions seem somewhat ridiculous, forgive me.
So, here are my questions:
1) Might the upload problems be caused by memory issues? The code was originally written to read everything at once by the original developer, but I have re-written it below to use a ByteArrayOutputStream and read the file chunk by chunk. I still worry that the InputStream is trying to read everything at once on initialization. Am I just misunderstanding InputStream, or does it behave more like a File pointer in C?
2) I dislike calling new everytime in the while loop-I suspect that, like in C, new memory is being allocated all the time, but I am not sure if calling null before re-initialization really helps here. Is this causing a leak here? I only ask because I presume that Java's Memory Management somehow ensures not to allow more memory to the heap and keeps track of references.
3) The uploading stops if the phone goes into standby. Is there anyway to keep the upload moving when this happens?
4) Might the PHP server code be missing something in terms of reporting networking errors/issues? I have included as much as I can for handling write errors, but I feel somehow this could be written better.
Also, I am not constrained to using HttpPut-this was simply a method suggested to me. I am open to changing things on the server side to support a better method of file transfer.
Android Java code (function in upload client):
