How do I delete files programmatically on Android?

by

Why don’t you test this with this code:

File fdelete = new File(uri.getPath());
if (fdelete.exists()) {
    if (fdelete.delete()) {
        System.out.println("file Deleted :" + uri.getPath());
    } else {
        System.out.println("file not Deleted :" + uri.getPath());
    }
}

I think part of the problem is you never try to delete the file, you just keep creating a variable that has a method call.

So in your case you could try:

File file = new File(uri.getPath());
file.delete();
if(file.exists()){
      file.getCanonicalFile().delete();
      if(file.exists()){
           getApplicationContext().deleteFile(file.getName());
      }
}

However I think that’s a little overkill.

You added a comment that you are using an external directory rather than a uri. So instead you should add something like:

String root = Environment.getExternalStorageDirectory().toString();
File file = new File(root + "/images/media/2918");

Then try to delete the file.
