I'm transfer snowflake animation and modify it to be appear on linear layout without blocking any components on relative view.

But I have problem to transfer GLSurfaceView (which is derived from openGL ) into linearlayout where it will overlapped or closing everthings components on Relative view.

GLSurfaceView glView = new GLSurfaceView(this);
glView.setDebugFlags(GLSurfaceView.DEBUG_CHECK_GL_ERROR);
glView.setRenderer(new FireRenderer(context)); //This line is important
container.addView(glView);

My problem here how can I modify the code so its animation can be appear on background without crossing to block everythings on relative background.

After Few times attempts, I've succeeded in my code which can be working on client side in sending and server won't stop stop executing after each time received file form client.

Client Side

import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.DataOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.net.Socket; public class ClientSend { /** * @param args */ public static void main(String[] args) throws IOException { // TODO Auto-generated method stub Socket sock = new Socket("192.168.9.6", 5991); //replace with your remote host static IP address. System.out.println("Connecting........."); File myFile = new File("C:/share_ex/"); File[] Files = myFile.listFiles(); OutputStream os = sock.getOutputStream(); DataOutputStream dos = new DataOutputStream(os); dos.writeInt(Files.length); for (int count=0;count<Files.length;count ++){ dos.writeUTF(Files[count].getName()); } for (int count=0;count<Files.length;count ++){ int filesize = (int) Files[count].length(); dos.writeInt(filesize); } for (int count=0;count<Files.length;count ++){ int filesize = (int) Files[count].length(); byte [] buffer = new byte [filesize]; //FileInputStream fis = new FileInputStream(myFile); FileInputStream fis = new FileInputStream(Files[count].toString()); BufferedInputStream bis = new BufferedInputStream(fis); //Sending file name and file size to the server bis.read(buffer, 0, buffer.length); //This line is important dos.write(buffer, 0, buffer.length); dos.flush(); //dos.close(); } //Closing socket //dos.close(); sock.close(); } }

okay, done i've settled by putting flag = false when it encountered number of file is reach to index array less one before max.
let said total file from client send is digit 2 but index 0 will stored digit 1, index 1 stored digit 2, while index 3 stored in nothings.

while(true && flag==true){ if (fileSize - count == 1 ){ // clientSocket.close(); flag=false; }

Here is my modified server's code:

import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.EOFException; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import java.util.ArrayList; public class ServerRun { /** * @param args */ public static void main(String[] args) throws IOException,EOFException { // TODO Auto-generated method stub FileOutputStream fos; BufferedOutputStream bos; OutputStream output; DataOutputStream dos; int len; int smblen; InputStream in; boolean flag=true; DataInputStream clientData; BufferedInputStream clientBuff; ServerSocket serverSocket = new ServerSocket(5991); Socket clientSocket = null; clientSocket = serverSocket.accept(); in = clientSocket.getInputStream(); //used clientData = new DataInputStream(in); //use clientBuff = new BufferedInputStream(in); //use if (flag==false){ clientSocket = serverSocket.accept(); } while(true && flag==true){ System.out.println("Starting..."); int fileSize = clientData.read(); ArrayList<File>files=new ArrayList<File>(fileSize); //store list of filename from client directory ArrayList<Integer>sizes = new ArrayList<Integer>(fileSize); //store file size from client //Start to accept those filename from server for (int count=0;count < fileSize;count ++){ File ff=new File(clientData.readUTF()); files.add(ff); } for (int count=0;count < fileSize;count ++){ sizes.add(clientData.readInt()); } for (int count =0;count < fileSize ;count ++){ if (fileSize - count == 1 ){ // clientSocket.close(); flag=false; } len=sizes.get(count); System.out.println("File Size ="+len); //output = new FileOutputStream("C:/share/" + fileName); output = new FileOutputStream("C:/share/" + files.get(count)); dos=new DataOutputStream(output); bos=new BufferedOutputStream(output); byte[] buffer = new byte[1024]; //byte[] buffer= new byte[len]; bos.write(buffer, 0, buffer.length); //This line is important while (len > 0 && (smblen = clientData.read(buffer)) > 0) { dos.write(buffer, 0, smblen); len = len - smblen; dos.flush(); } } } } //end loop }

Another Question is here because my server will be stop running after one time transfer is done, I want to keep it running, How can I do it? I mean how can i keep
clientSocket = serverSocket.accept() to open the port for running and waiting to received request from client after one time send is done.

Appreciate thankful to any helps.

Currently, I've created one android apps to enables to send/transfer file from internal storage to remote server via WAN when I stayed in outside.

All files is success transfer but at the end my server is ended up with this message, ( the picture/music files will be success rendered when I quit out this programs )

My problem is here how can I modify to server side code to avoid this problems on future. Appreciate to any helps and thanks.

Thanks for all your previous guide,

This time I've success to transfer a bunch of file from one directory to another directory but the the server's connection will be reset each time transfer is done.

the server will simply returns this message:

My problem here how can I ensure continues running of server without reset each time transfer is completed? Thanks to any mindful helps.

okay....thanks to admin by help me putting code tag.

Anyone can help to solve here problem,,,,,,thanks

To Campbell Ritchie,

I can pass through the first file processing but I'll be stop at second file processing when running in the for loop process at client
the problem i found at os=clientData.getOutputStream() here where it will be stuck at second times in loop process.

I've modified the above code.

There is not problem in client side, no matter my client side sending how many but it could only able transfer one file to server side

at last it returns to this error:

Exception in thread "main" java.net.SocketException: Socket is closed

My problem is here how can i detect/scan number of file received from client by modifying server side coding then i can used to performed looping to write output file. Appreciate any help.
