    <p>I want to download file from server. File is created successfully in my android device but that file is empty file. it is not writing anything in file.</p> <p>My filereading code is as follows:</p> <pre><code>URL url = new URL(urlString); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setRequestMethod("GET"); urlConnection.setDoOutput(true); //connect urlConnection.connect(); File SDCardRoot = Environment.getExternalStorageDirectory(); //create a new file, to save the downloaded file File file = new File(SDCardRoot,pos); FileOutputStream fileOutput = new FileOutputStream(file); //Stream used for reading the data from the internet InputStream inputStream = urlConnection.getInputStream(); //this is the total size of the file which we are downloading totalSize = urlConnection.getContentLength(); //create a buffer... byte[] buffer = new byte[1024]; int bufferLength = 0; while ( (bufferLength = inputStream.read(buffer)) &gt; 0 ) { fileOutput.write(buffer, 0, bufferLength); downloadedSize += bufferLength; } fileOutput.close(); } </code></pre> <p>I have debugged the code. There is something wrong in while ( (bufferLength = inputStream.read(buffer)) > 0 ) condition as the compiler didnt go inside this loop.</p> <p>My log cat error:</p> <pre><code>ERROR/ActivityThread(8218): Activity com.sec.android.app.myfiles.DetailsActivity has leaked IntentReceiver com.sec.android.app.myfiles.DetailsActivity$4@42760570 that was originally registered here.

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).
