Cannot delete files transfered from computer in Android -

i'm making video downloader app , i've got no problems saving , deleting files downloaded app external storage file transfered computer cannot deleted app.

this real problem it's 1 of key features want. here's code i'm using:

public boolean deletedatafromstorage(data todelete) {      //the file object deleted     file f = null;      log.e(tag, "deleting " + todelete.filename);      // delete file storage     try {          // file delete         f = new file(environment.getexternalstoragedirectory().getcanonicalpath() + directory + todelete.filename);      } catch (ioexception e) {          log.e(tag, e.tostring());          // print stack trace         e.printstacktrace();     }      // delete file     if(f.delete()) {         return true;     } else {          log.e(tag, "failed delete " + todelete.filename);         return false;     } } 

as f.delete() function doesn't throw exceptions have no idea problem is. thing can think of app doesn't have permission delete file created in windows , yet have downloaded apps app store have no problem deleting transfered files.

any appreciated.

as per comment, since f.isfile() , f.exists() returns false, f not file, in other words, you're getting path wrong.

print logs f.getabsolutepath(), check is, , should easy fix.
