I can upload less then 8 MB , while trying to upload above 10 MB it throws "OutOfMemoryError", so I add<br> <code>conn.setFixedLengthStreamingMode(fileInputStream.available());</code> in my code,It also throws the following Exception</p> <pre><code>07-08 10:57:22.649: W/System.err(31383): java.io.IOException: expected 860 bytes but received 4096 07-08 10:57:22.649: W/System.err(31383): at libcore.net.http.FixedLengthOutputStream.write(FixedLengthOutputStream.java:39) 07-08 10:57:22.649: W/System.err(31383): at java.io.DataOutputStream.write(DataOutputStream.java:98) 07-08 10:57:22.649: W/System.err(31383): at com.ams.utilities.PhotoUploadAsyncTask.doInBackground(PhotoUploadAsyncTask.java:273) 07-08 10:57:22.649: W/System.err(31383): at com.ams.utilities.PhotoUploadAsyncTask.doInBackground(PhotoUploadAsyncTask.java:1) 07-08 10:57:22.656: W/System.err(31383): at android.os.AsyncTask$2.call(AsyncTask.java:287) 07-08 10:57:22.656: W/System.err(31383): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) 07-08 10:57:22.656: W/System.err(31383): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 07-08 10:57:22.664: W/System.err(31383): at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:230) 07-08 10:57:22.672: W/System.err(31383): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) 07-08 10:57:22.688: W/System.err(31383): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) 07-08 10:57:22.703: W/System.err(31383): at java.lang.Thread.run(Thread.java:856) </code></pre> <p>the following code i use to Upload Zip file</p> <pre><code>DataOutputStream os = null; HttpsURLConnection conn = null ; String strBoundary = "---------------------------14737809831466499882746641449"; String endLine = "\r\n"; conn = (HttpsURLConnection) new URL(url).openConnection(); if(fileInputStream != null) conn.setFixedLengthStreamingMode(fileInputStream.available()); conn.setRequestMethod("POST"); conn.setRequestProperty( "Content-Type", "multipart/form-data;boundary="+strBoundary); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Accept", "text/xml"); conn.connect(); os = new DataOutputStream(conn.getOutputStream()); os.write(("--" + strBoundary +endLine).getBytes()); os.write((encodePostBody(postData, strBoundary)).getBytes()); os.write((endLine + "--" + strBoundary + endLine).getBytes()); os.write(("Content-Disposition: form-data; name=\"cloud_photos\"; filename=\"cloud_photos.zip\"" + endLine).getBytes()); os.write(("Content-Type: application/octet-stream" + endLine + endLine).getBytes()); if(fileInputStream != null){ long lengthOfFile = zipfilePath.length(); //fileInputStream.available();// int bytesAvailable = fileInputStream.available(); int maxBufferSize = 4 * 1024; LogAMS.d(TAG, "bytesAvailable="+bytesAvailable); int bufferSize = Math.min(bytesAvailable, maxBufferSize); byte[] buffer = new byte[bufferSize]; int total = 0; // read file and write it into form... int bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead &gt; 0){ total += bytesRead; os.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); int progress = (int)((total*100) / lengthOfFile); if(progress &lt;= 98){ if(progress % 20 == 0) publishProgress(progress); }else{ if(progress == 99) publishProgress(progress); } bufferSize = Math.min(bytesAvailable,maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } } } os.write((endLine + "--" + strBoundary + endLine).getBytes()); // fileInputStream.close(); os.flush(); os.close(); os = null; return parseUploadResponse(conn.getInputStream()); </code></pre> <p>I need to upload it in chunks.If anyone could give me a suggestions as to the best approach, I would be very grateful.</p> <p>Thanks in advance</p>

    1. COYour code looks very confusing. Problem you are facing is that you have allocated larger buffer than your data is ( int maxBufferSize = 4 * 1024;). Anytime you have to do something complicated, google and find out if there is open-source library to do that. Why don't you integrate http://loopj.com/android-async-http/ (refer to section - Uploading Files with RequestParams)

    2. COSorry for the late response, here is some network problem. I will try your suggestions. Actually my need is upload selected photo(maximum 120 photo) as zipped format in background service and get current upload progress in percentage.

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).
