    <p>I am pretty much new to android development, and I am trying to upload a file of size 25 to 50 MB to a web server, and am getting the out of memory error. I am struggling for past 2 days and have no clue, where I am going wrong.</p> <p>Got any suggestions on where I am going wrong?</p> <p>The code I am working on is </p> <pre><code>private FileInputStream fileInputStream = null; private int bytesavailable,buffersize,bytesRead ; byte buff[]; int maxBufferSize = 1*1024*1024; String server_url ="server_url"; DataOutputStream dos; String Builder response = new String Builder(); String body = "boundary values"; String body2 = "Boundary values"; URL url = null; try { url = new URL(server_url); } catch (MalformedURLException e1) { e1.printStackTrace(); } HttpURLConnection conn = null; try { conn = (HttpURLConnection) url.openConnection(); } catch (IOException e) { e.printStackTrace(); } try { conn.setRequestMethod("POST"); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestProperty("Connection","Keep-Alive"); conn.setRequestProperty("Content-Type","multipart/form-data; boundary=A300x"); conn.connect(); dos = new DataOutputStream(conn.getOutputStream()); dos.writeBytes(body); File inputfile = new File(sourceFile); fileInputStream = new FileInputStream(inputfile); bytesavailable = fileInputStream.available(); buffersize = Math.min(bytesavailable, maxBufferSize); buff = new byte[buffersize]; bytesRead = fileInputStream.read(buff, 0, buffersize); while (bytesRead &gt; 0) { dos.write(buff, 0, buffersize); dos.flush(); bytesavailable = fileInputStream.available(); buffersize = Math.min(bytesavailable, maxBufferSize); bytesRead = fileInputStream.read(buff, 0, buffersize); } fileInputStream.close(); dos.write("\r\n".getBytes()); dos.write(body2.getBytes()); dos.flush(); dos.close(); } catch (ProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } int iresponse = 0; try { iresponse = conn.getResponseCode(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } //printStream(conn.getInputStream()); if (iresponse == HttpURLConnection.HTTP_OK) { BufferedReader input = null; try { input = new BufferedReader(new InputStreamReader(conn.getInputStream()), 8192); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } String line = null; try { while ((line = input.readLine()) != null) response.append(line); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { input.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return response.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.

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).
