I would like to obtain like some this:
But I don't know how I can to obtain the percentage.
I've read this posts:
But I haven't gotten any good result =(
¿Any idea?
I can get the total size and the bytes downloaded for a file, but I don't know how I can get that the progress bar shows these information in a percentage wa
int sizeIndex = c.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES);
int downloadedIndex = c.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR);
int size = c.getInt(sizeIndex);
int downloaded = c.getInt(downloadedIndex);
int percentage = (downloaded * 100 / size);

Just create a notification when you start downloading
mNotifyManager = (NotificationManager) getApplicationContext().getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle("Downloading file")
.setContentText("Downloading... 0%")
.setSmallIcon(R.drawable.your_icon);
mNotifyManager.notify(YOUR_TAG, mBuilder.build());
And then you can update progress calling that same notification whit YOUR_TAG
mBuilder.setContentText("Downloading... " + CURRENT_BYTES * 100.0/TOTAL_BYTES + "%")
.setProgress(TOTAL_BYTES, CURRENT_BYTES, false);
mNotifyManager.notify(YOUR_TAG, mBuilder.build());
