    <p>Trying to create and write to a file, but i get a <code>FileNotFoundException</code> every time, here is the method i am using:</p> <pre><code>public void saveFileAsPRN(Context context){ byte[] dataFile = getPrintableFileData(); String filename = "TestPrn.prn"; // instantiate a file object using the path File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), filename); Log.e(TAG, Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString()); //determine if the media is mounted with read &amp; write access String state = Environment.getExternalStorageState(); if (Environment.MEDIA_MOUNTED.equals(state)) { Log.e(TAG, "media mounted"); //good }else{ Log.e(TAG, "media NOT mounted"); //bad } //create directory if it does not exist //the default Download directory should always exist if (!file.mkdirs()) { Log.e(TAG, "Directory not created"); } // determine if the file exists, create it if it does not if(!file.exists()){ try { Log.e(TAG, "File does not exist, creating.."); file.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }else{ Log.e(TAG, "File Exists"); } //this makes the blank file visible in the file browser MediaScannerConnection.scanFile(context, new String[]{Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString() + "/" + filename}, null, null); //create output stream - send data; saving to file OutputStream out = null; try { FileOutputStream fos = null; fos = new FileOutputStream(file); // &lt;---- CRASHES HERE; FileNotFoundException out = new BufferedOutputStream(fos); out.write(dataFile); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { try { out.flush(); out.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } </code></pre> <p>A <code>FileNotFoundException</code> is raised on the following line: </p> <pre><code>fos = new FileOutputStream(file); // &lt;---- CRASHES HERE; </code></pre> <p>The directory Exists, and a blank file is created in the target directory (visible by browsing target folder on PC).</p> <p>Calling the method <code>canWrite()</code> on the <code>File</code> object returns true - i have write access.</p> <p>The manifest contains: <code>android.permission.WRITE_EXTERNAL_STORAGE</code>"</p> <p>So i'm out of ideas, i see several people have similar issues, but i cant find an answer.</p>

    1. COWhat does http://docs.oracle.com/javase/7/docs/api/java/io/File.html#createNewFile() return? Also, won't `mkdirs()` create your file as a directory?

    2. COcheck for reader if you are able to read it and also try PrintWriter for writing data to the file, it can directly take the File object.

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.
