How to privately store videos on sd card
<p>I'm a beginner to android and need some help. The app I'm making lets the user purchase and download high resolution videos from a server. These videos are stored on the SD card.</p>

<p>This creates two problems for me:</p>

<ol>
<li>Once on the SD card the files can be
publicly viewed and copied to other locations.</li>
<li>When the app is uninstalled the
files remain on the SD card and take
up a lot of space.</li>
</ol>

<p><strong>My questions:</strong></p>

<ol>
<li><p>Can I make the videos private to my
app? From what I understand storing
to Internal Storage provides that
privacy. However, Internal Storage
is not the SD card and therefore
provides only limited space - and
the videos require a lot of space.</p></li>
<li><p>When the app is uninstalled - is
there a way to make sure the videos
are removed from the SD card.</p></li>
</ol>

<p>Please tell me if you need more information! Thanks for being a great community! </p>
