This method is causing problem @Override protected void onVisibilityChanged(@NonNull View changedView, int visibility) { super.onVisibilityChanged(changedView, visibility);

if (visibility == View.INVISIBLE) { timer.cancel(); } else { timer = new Timer(); timer.scheduleAtFixedRate(new TimerTask() { @Override public void run() { ((Activity) context).runOnUiThread(new Runnable() { @Override public void run() { NSidedProgressBar.this.invalidate(); } }); } }, 0, 1000 / refreshRate); } }

It works seemlessly on above android 6

Rectangle shape

Thanks for this Progress bar, it's really awesome!

One question though, if I wanted to make a rectangular progress bar, instead of the square one, for instance, around the borders of a button. would that be possible?

N-SidedProgressBar context memory leak

Good day. In the process of using leakCanary detects a leak. Refers to the context of the N-SidedProgressBar.

I use the progress bar in the Fragment. It is likely that the fragment can not be destroyed, because the progress bar keeps the weak to activity. It is probably necessary to free the context in the onDetachedFromWindow () method.
