FilenameFilter has a single method "accept(File dir, String filename)" which
returns true if the given parameters are what you're looking for.

So you implement a class that extends FilenameFilter and override the accept
method to return true if the given parameters are what you're looking for.
So in your case you could check "filename" for starting with "voice" and
ending in ".amr".

Then you use the File.list() method with an instance of your newly defined
class to get all the files that match your criteria. Then it's a simple
matter of iterating the list and calling File.delete().

Hope that helps.

And do test thoroughly so you don't end up deleting all of the user's SD
card contents =P

You can use File apis as follows
   File f=new File("/sdcard");
if(f.isDirectory()){
 String files[]=  f.list();
 for(int i=0;iExcept that hard-coding "/sdcard" is bad - it's "/mnt/sdcard" in Froyo. 
Use Environment.getExternalStorageDirectory instead.
