In an android app, I download a file from server. File is downloaded in /downloads/store_downloads/file.
Problem
I am trying to delete the store_downloads directory and all the files in it.
I wrote following code to do it.
File directory = new File(Environment.DIRECTORY_DOWNLOADS+"/store_downloads");
if(directory.exists()) {
File allContents = directory.listFiles();
if(allContents != null) {
for (File subFile : allContents) {
subFile.delete();
}
}
directory.delete();
}
but directory.exists always returns false.
Question
What am I doing wrong here?

Also note thatdirectory.exists()introduces a possible race condition. In between inter-opting with the file and that line it may have been removed/changed/something. Rule of thumb: If you are going to interact with a file right after doing some kind of 'file exists' check, the file exists check is redundant. Just catch the exception, if any.
