How to send a File to Server in android programming

This is an easy Android application which allows to send a file in any format to a remote server. Server acts as loacalhost and create a button in a linear layout and the oprationvwill taking places in the android app is on button press. It will allows to send a file to server.There are mainly 4  portions for this operations. First one is an input device, which is an android device who send file to the server :- easyClientActivity.java.

easyClientActivity.java has the code for sending file. next one is main.xml, which creates the layout and user interface for the application. 3rd one is AndroidManifest.xml , it has the codes for some permission for using the network operations. main.java is the 4th module which comprises the code for server portion, allows to recieve the file.

easyClientActivity.java

  package lakj.comspace.easyclient; import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class SimpleClientActivity extends Activity { private Socket socketforclient; private FileInputStream inputStreamForFile; private BufferedInputStream streamForBufferedInput; private OutputStream stremForOutput; private Button SendButton; private TextView TextviewFortext; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); SendButton = (Button) findViewById(R.id.SendButton1); //reference to the send SendButton TextviewFortext = (TextView) findViewById(R.id.TextviewFortextView1); //reference to the TextviewFortext view //Button press event listener SendButton.setOnClickListener(new View.OnClickListener() { public void onClick(View Viewv) { File file = new File("/mnt/sdcard/input.fileextension"); try { socketforclient = new Socket("10.0.2.2", 4444); byte[] ByteArrayForMe = new byte[(int) file.length()]; //create a byte array to file inputStreamForFile = new FileInputStream(file); streamForBufferedInput = new BufferedInputStream(inputStreamForFile); streamForBufferedInput.read(ByteArrayForMe, 0, ByteArrayForMe.length); //read the file stremForOutput = socketforclient.getOutputStream(); stremForOutput.write(ByteArrayForMe, 0, ByteArrayForMe.length); //write file to the output stream byte by byte stremForOutput.flush(); streamForBufferedInput.close(); stremForOutput.close(); socketforclient.close(); TextviewFortext.setText("File Sent"); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }); } }  

Main.Xml

  <linearlayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"> <textview android:id="@+id/textView1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textappearance="?android:attr/textAppearanceLarge"> <button android:id="@+id/button1" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Send"> </button></textview></linearlayout>  

AndroidManifest.xml

  <manifest android:versioncode="1" android:versionname="1.0" package="lakj.comspace.simpleclient" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-sdk android:minsdkversion="10"> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name"> <activity android:label="@string/app_name" android:name=".SimpleClientActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"> <category android:name="android.intent.category.LAUNCHER"> </category></action></intent-filter> </activity> </application> </uses-sdk></manifest>  

main.java

  package serverwithdata; import java.io.BufferedOutputStream; import java.io.fileoutputdatastream; import java.io.IOException; import java.io.fileinputdatastream; import java.net.ServerSocket; import java.net.Socket; public class Main { private static ServerSocket serverSocket; private static Socket clientSocket; private static fileinputdatastream fileinputdatastream; private static fileoutputdatastream fileoutputdatastream; private static BufferedOutputStream bufferedOutputStream; private static int filesize = 10000000; private static int bytesReadData; private static int LiveData = 0; public static void main(String[] args) throws IOException { serverSocket = new ServerSocket(4444); //Server socket System.out.println("Server started. Listening to the port 4444"); clientSocket = serverSocket.accept(); byte[] BytesArrayforData = new byte[filesize]; fileinputdatastream = clientSocket.getfileinputdatastream(); fileoutputdatastream = new fileoutputdatastream("D:\\output.jpg"); bufferedOutputStream = new BufferedOutputStream(fileoutputdatastream); System.out.println("Server ready for accept file and working for this"); bytesReadData = fileinputdatastream.read(BytesArrayforData, 0, BytesArrayforData.length); LiveData = bytesReadData; do { bytesReadData = fileinputdatastream.read(BytesArrayforData, LiveData, (BytesArrayforData.length - LiveData)); if (bytesReadData >= 0) { LiveData += bytesReadData; } } while (bytesReadData > -1); bufferedOutputStream.write(BytesArrayforData, 0, LiveData); bufferedOutputStream.flush(); bufferedOutputStream.close(); fileinputdatastream.close(); clientSocket.close(); serverSocket.close(); System.out.println("Server has got the file you send from clent device"); } }
