Hello Matt!

I like your SecretTextView and I'm going to use it in my project. Could you please provide licence information? It is very important for me.

I see in your Manifest, minSDK=11.
Could you please make SecretTextView compatible with Android 2.x?
(Is NineOldAndroid library helpful to backport animation of SecretTextView?)

Once show() or hide() is called, mIsReset becomes always true and setText() does not work.
I fix it as below. Is it ok?

private void resetSpannableString(double percent){
mIsReset = true;
...
mIsReset = false;
}

remove mIsReset = false; from resetIfNeeded()

Tks for your nice code first, but...
while running your demo, I found the memory usage like this (tested on Genymotion 2.4 with intel acceleration, x64, android 5.1.0 on nexus 4):

Obviously, it's cause by:

I have fix that problem, pls see you pull request.
The work I did is:
1, Use a MutableForegroundColorSpan to maintain the foreground color, instead new a ForeGroundColorSpan every time.
2, Change the MutableForegroundColorSpan object's color when needed.

Here is memory usage after my fix(tested on Genymotion 2.4 with intel acceleration, x64, android 5.1.0 on nexus 4):
