Answer 1

downloadReference = dm.enqueue(request) créer une nouvelle tâche et retourner une nouvelle id.You devrait utiliser l'ID précédent.

public void cancelDownload(View view) { 
    //downloadReference= intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0); 
    //downloadReference = dm.enqueue(request); 
    dm.remove(enqueue); 

    Toast.makeText(DownloadManagerActivity.this, "Download Cancelled", Toast.LENGTH_SHORT).show(); 

}
