Answer 1

when you're submitting the file to the download manager check if the file already exists. then delete it.

private boolean isFileExists(String filename){

    File folder1 = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + filename);
    return folder1.exists();


}

private boolean deleteFile( String filename){

    File folder1 = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + filename);
    return folder1.delete();


}
