Send .txt file, document file to the server in android

Question

I am developing an application in which I am sending data in string format to the server. Below is my code. It is working fine. But now my question is how can I send whole .

Answer 1

HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;
String pathToOurFile = "/data/file_to_send.mp3";
String urlServer = "http://192.168.1.1/handle_upload.php";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

try
{
    FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

    URL url = new URL(urlServer);
    connection = (HttpURLConnection) url.openConnection();

    // Allow Inputs & Outputs.
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Set HTTP method to POST.
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

    outputStream = new DataOutputStream( connection.getOutputStream() );
    outputStream.writeBytes(twoHyphens + boundary + lineEnd);
    outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
    outputStream.writeBytes(lineEnd);

    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    buffer = new byte[bufferSize];

    // Read file
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

    while (bytesRead > 0)
    {
        outputStream.write(buffer, 0, bufferSize);
        bytesAvailable = fileInputStream.available();
        bufferSize = Math.min(bytesAvailable, maxBufferSize);
        bytesRead = fileInputStream.read(buffer, 0, bufferSize);
    }

    outputStream.writeBytes(lineEnd);
    outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

    // Responses from the server (code and message)
    serverResponseCode = connection.getResponseCode();
    serverResponseMessage = connection.getResponseMessage();

    fileInputStream.close();
    outputStream.flush();
    outputStream.close();
}
catch (Exception ex)
{
    //Exception handling
}

Try this code.. this is perfectly working for me..

public class ServerActivity extends Activity {

    TextView messageText;
    Button uploadButton;
    int serverResponseCode = 0;
    ProgressDialog dialog = null;

    String upLoadServerUri = null;

    final String uploadFilePath = "mypath";
     final String uploadFileName = "myfile";


    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_server);

        uploadButton = (Button)findViewById(R.id.uploadButton);
        messageText  = (TextView)findViewById(R.id.messageText);

        messageText.setText("Uploading file path :- 'path"+uploadFileName+"'");


        upLoadServerUri = "serverpath";

        uploadButton.setOnClickListener(new OnClickListener() 
        {            
            @Override
            public void onClick(View v)
            {

                dialog = ProgressDialog.show(UploadToServer.this, "", "Uploading file...", true);

                new Thread(new Runnable()
                {
                        public void run() 
                        {
                             runOnUiThread(new Runnable() 
                             {
                                    public void run() 
                                    {
                                        messageText.setText("uploading started.....");
                                    }
                                });                      

                             uploadFile(uploadFilePath + "" + uploadFileName);

                        }
                      }).start();        
                }

try this code to create txt file write string to that file and send it to server...

File f = new File(Environment.getExternalStorageDirectory(),"new");
        if(!f.exists())
        {
            f.mkdir();
        }
        File file = new File("new.txt");
        FileWriter w = new FileWriter("/sdcard/new/new.txt");
        BufferedWriter out = new BufferedWriter(w);
        out.write(data);
        out.flush();
        out.close();
                          String file_name = "/sdcard/new/new.txt";

        File file1 = new File(file_name);  
        socket = new Socket("117.218.28.70", 2020);

        ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());  
        ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());  

        oos.writeObject(file1.getName());  

        FileInputStream fis = new FileInputStream(file1);  
        byte [] buffer = new byte[450000];  
        Integer bytesRead = 0;  

        while ((bytesRead = fis.read(buffer)) > 0) 
        {  
            oos.writeObject(bytesRead);  
            oos.writeObject(Arrays.copyOf(buffer, buffer.length));  
        }  
        oos.close();  
        ois.close();  
        System.exit(0);

This code uploads data (images, mp3′s, text files etc..) to HTTP server

HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;

String pathToOurFile = "/data/file_to_send.mp3";
String urlServer = "http://192.168.1.1/handle_upload.php";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

try
{
FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();

// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);

// Enable POST method
connection.setRequestMethod("POST");

connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/formdata;boundary="+boundary);

outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data;
name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);

bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];

// Read file
bytesRead = fileInputStream.read(buffer, 0, bufferSize);

while (bytesRead > 0)
{
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}

outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// Responses from the server (code and message)
serverResponseCode = connection.getResponseCode();
serverResponseMessage = connection.getResponseMessage();

fileInputStream.close();
outputStream.flush();
outputStream.close();
}
catch (Exception ex)
{
//Exception handling
  }
