Perform action as soon as something is copied to the SD Card on Android
<p>I am currently looking into developing an android app which will automatically copy files from select directories on the SD card to DropBox. </p>

<p>I am assuming that this would be done using a service, but how do I get the app to perform a particular action when something is saved to the SD card. </p>

<p>Thanks for any help you can provide. </p>
