    <p>I'm trying to send a picture I choose from the gallery on my phone, and send that picture from the phone to my PC, when I click on the button it should take the picture's path and put it in a file, and transfer it to my PC. I've checked the code on my PC - for both sides - and it worked totally fine.</p> <p>When I test it out, nothing happens!</p> <p>Here is the code:</p> <p>Server side:</p> <pre><code> import java.io.*; import java.net.*; public class FileServer { public static void main(String[] args) throws IOException { int filesize=6022386; // filesize temporary hardcoded long start = System.currentTimeMillis(); int bytesRead; int current = 0; // create socket ServerSocket servsock = new ServerSocket(1149); while (true) { System.out.println("Waiting..."); Socket sock = servsock.accept(); System.out.println("Accepted connection : " + sock); // receive file byte [] mybytearray = new byte [filesize]; InputStream is = sock.getInputStream(); FileOutputStream fos = new FileOutputStream("C:\\Users\\Arwa\\Documents\\WebOffice.jpg"); // destination path and name of file BufferedOutputStream bos = new BufferedOutputStream(fos); bytesRead = is.read(mybytearray,0,mybytearray.length); current = bytesRead; // thanks to A. Cádiz for the bug fix do { bytesRead = is.read(mybytearray, current, (mybytearray.length-current)); if(bytesRead &gt;= 0) current += bytesRead; } while(bytesRead &gt; -1); bos.write(mybytearray, 0 , current); bos.flush(); long end = System.currentTimeMillis(); System.out.println(end-start); bos.close(); sock.close(); } } } </code></pre> <hr> <p>Client side (Android):</p> <pre><code> package com.arwa.file.send; import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.ObjectOutputStream; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException; import android.app.Activity; import android.content.Intent; import android.database.Cursor; import android.net.Uri; import android.os.Bundle; import android.provider.MediaStore; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.ImageView; import android.widget.TextView; public class SendfileActivity extends Activity { /** Called when the activity is first created. */ private static final int SELECT_PICTURE = 1; private String selectedImagePath; private ImageView img; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); System.out.println("34"); img = (ImageView) findViewById(R.id.ivPic); System.out.println("36"); ((Button) findViewById(R.id.bBrowse)) .setOnClickListener(new OnClickListener() { public void onClick(View arg0) { System.out.println("40"); Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult( Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE); System.out.println("47"); } }); ; System.out.println("51"); Button send = (Button) findViewById(R.id.bSend); final TextView status = (TextView) findViewById(R.id.tvStatus); send.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { Socket sock; try { sock = new Socket("MY_PCs_IP", 1149); System.out.println("Connecting..."); // sendfile File myFile = new File (selectedImagePath); byte [] mybytearray = new byte [(int)myFile.length()]; FileInputStream fis = new FileInputStream(myFile); BufferedInputStream bis = new BufferedInputStream(fis); bis.read(mybytearray,0,mybytearray.length); OutputStream os = sock.getOutputStream(); System.out.println("Sending..."); os.write(mybytearray,0,mybytearray.length); os.flush(); sock.close(); } catch (UnknownHostException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); } public void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK) { if (requestCode == SELECT_PICTURE) { Uri selectedImageUri = data.getData(); selectedImagePath = getPath(selectedImageUri); TextView path = (TextView) findViewById(R.id.tvPath); path.setText("Image Path : " + selectedImagePath); img.setImageURI(selectedImageUri); } } } public String getPath(Uri uri) { String[] projection = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(uri, projection, null, null, null); int column_index = cursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } } </code></pre> <p>XML code: </p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/tvStatus" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /&gt; &lt;TextView android:id="@+id/tvPath" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Path: " /&gt; &lt;Button android:id="@+id/bBrowse" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Browse" &gt; &lt;/Button&gt; &lt;Button android:id="@+id/bSend" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Send" /&gt; &lt;ImageView android:id="@+id/ivPic" android:layout_width="wrap_content" android:layout_height="wrap_content" &gt; &lt;/ImageView&gt; &lt;/LinearLayout&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
