what does it mean to delete a file on android
<p>Naturally I thought to delete a file means to remove it from existence. So when I do</p>

<pre><code>File file = new File(absPath);
....//add content
file.delete();
</code></pre>

<p>I expect that no further operation can be executed on <code>file</code> or it would throw an exception. But how come I can still add content to the file such as shown here <a href="https://stackoverflow.com/questions/11846108/android-saving-bitmap-to-sd-card">Android saving Bitmap to SD card</a>. So how do I delete a file so that it is completely gone? So that when someone go look through file manager, the file is no longer there? I am not in a position to test this now, so I was hoping for authoritative reference.</p>
