How to delete a file from SD card?

Question

I am creating a file to send as an attachment to an email. Now I want to delete the image after sending the email. Is there a way to delete the file?

I have tried myFile.delete(); but it didn't delete the file.

I'm using this code for Android, so the programming language is Java using the usual Android ways to access the SD card. I am deleting the file in the onActivityResult method, when an Intent is returned to the screen after sending an email.

private boolean deleteFromExternalStorage(File file) {
                        String fileName = "/Music/";
                        String myPath= Environment.getExternalStorageDirectory().getAbsolutePath() + fileName;

                        file = new File(myPath);
                        System.out.println("fullPath - " + myPath);
                            if (file.exists() && file.canRead()) {
                                System.out.println(" Test - ");
                                file.delete();
                                return false; // File exists
                            }
                            System.out.println(" Test2 - ");
                            return true; // File not exists
                    }

Sorry: There is a mistake in my code before because of the site validation.

String myFile = "/Name Folder/File.jpg";  

String myPath = Environment.getExternalStorageDirectory()+myFile;  

File f = new File(myPath);
Boolean deleted = f.delete();

I think is clear... First you must to know your file location. Second,,, Environment.getExternalStorageDirectory() is a method who gets your app directory. Lastly the class File who handle your file...
