I had similar issue once, I solved it using CountDownTimer. Similar to how superfell suggested, you can call progress update of AsyncTask regularly while downloading file.

And call the Notification Manager only at specific interval. After calling start of CountDownTimer, it will call onTick function after every fixed interval of time, and will call onFinish either when timer is timed out or when called explicitly. I too experienced this problem. I was updating the progress bar WAY too often even when the progress didn't change , here's how I fixed that:.

I had the same issue that I was not able to update the progress bar notification even with an interval of 3 seconds so after hours of digging I came to realize the fact that whenever we update the notification the RemoteView object must be re-instantiated and re-initialized to the Notification object's contentView.

After doing this I was able to update the Notification progress bar with an interval of msms for a very long period without facing any UI blocking. Note: If you don't agree you can verify this answer by running this snippet after commenting out the marked line and see the difference. It may take about 5mins to start the severe UI blockage which will heat up your device and may stop functioning. I tried with an S3 mini with Android 4. Builder is used for the same purpose.

Note: The reason to write this answer after 3 years of the question is because I wonder that I did not find even a single stackoverflow answer or other blog post handling this serious issue with this very simple solution. Here is my copy pasted code that you can use directly I use the same code for updating a notification layout which contains two ProgressBars and four TextViews with a frequency of msms.
