    <p>I'm developing an application that can send different files to web server.Also I want to send large files, in able to do this I need to chunk the files. But when I'm sending the files to server nothing is uploaded. I don't know if there's error on how I'm sending the files and it gives an error 500 (internal server error) on my response.I don't think the server is the problem because when I'm uploading a file using multiPartEntity it works but when Im using BufferedInputStream and DataOutputStream it doesn't work. Please help me and tell what's wrong on my code why it can't send my files. Here's I got so far: </p> <pre><code> String samplefile = "storage/sdcard0/Pictures/Images/picture.jpg"; File mFile = new File(samplefile); int mychunkSize = 2048 * 1024; final long size = mFile.length(); final long chunks = size &lt; mychunkSize? 1: (mFile.length() / mychunkSize); int chunkId = 0; try { BufferedInputStream stream = new BufferedInputStream(new FileInputStream(mFile)); String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "-------------------------acebdf13572468";// random data for (chunkId = 0; chunkId &lt; chunks; chunkId++) { URL url = new URL(urlString); // Open a HTTP connection to the URL HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setReadTimeout(20000 /* milliseconds */); conn.setConnectTimeout(20000 /* milliseconds */); // Allow Inputs conn.setDoInput(true); // Allow Outputs conn.setDoOutput(true); // Don't use a cached copy. conn.setUseCaches(false); // Use a post method. conn.setRequestMethod("POST"); String encoded = Base64.encodeToString((_username+":"+_password).getBytes(),Base64.NO_WRAP); conn.setRequestProperty("Authorization", "Basic "+encoded); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); DataOutputStream dos = new DataOutputStream( conn.getOutputStream() ); dos.writeBytes(twoHyphens + boundary + lineEnd); String param1 = ""+chunkId; String param2 = ""+chunks; String param3 = mFile.getName(); String param4 = samplefile; // Send parameter #file dos.writeBytes("Content-Disposition: form-data; name=\"fieldNameHere\";filename=\"" + param3 + "\"" + lineEnd); // filename is the Name of the File to be uploaded dos.writeBytes("Content-Type: image/jpeg" + lineEnd); dos.writeBytes(lineEnd); // Send parameter #chunks dos.writeBytes("Content-Disposition: form-data; name=\"chunk\"" + lineEnd); dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd); dos.writeBytes("Content-Length: " + param2.length() + lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(param2 + lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); // Send parameter #name dos.writeBytes("Content-Disposition: form-data; name=\"name\"" + lineEnd); dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd); dos.writeBytes("Content-Length: " + param3.length() + lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(param3 + lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); byte[] buffer = new byte[mychunkSize]; stream.read(buffer); dos.write(buffer); dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); dos.flush(); dos.close(); } } catch (Exception e) { Log.e("Error Uploading Files", e.toString()); } </code></pre>

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.
