[android-developers] Re: how to list files on SD card
You can use File apis as follows
File f=new File(/sdcard);
if(f.isDirectory()){
String files[]= f.list();
for(int i=0;ifiles.length;i++){
Log.d(,files[i]);
}
And identify your file and construct file path and delete

Except that hard-coding /sdcard is bad - it's /mnt/sdcard in Froyo.
Use Environment.getExternalStorageDirectory instead.

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 - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.
