updateDrawState(TextPaint tp) stuck in an infinite loop on certain devices

Question

I am using an alpha interpolation on a custom CharacterStyle by setting an alpha value mAlpha and then updating the color in updateDrawState(TextPaint tp).

I'm running into an issue on newer Android devices, specifically devices running API 23 don't seem to render the Spans at all. On older devices the updates work properly.

Has anyone dealt with this issue?

Here is the code for the alpha being set inside onDraw in a custom EditText for some weird reason the characters sometimes do not show up on certain devices on other devices the animation works perfectly:

// If the view is animating (meaning we set the text) go ahead and draw the animations
    if (mIsAnimating) {

        long delta = AnimationUtils.currentAnimationTimeMillis() - mStart;

        // Initialize our word span
        FadeWordSpan[] words = mFadeText.getSpans(0, mFadeText.length(), FadeWordSpan.class);

        // Get our length
        final int length = words.length;

        // For each letter animate in the word
        for (int i = 0; i < length; i++) {

            // Get our word
            FadeWordSpan word = words[i];

            long value = (delta - (i * mDurationPerWord));

            // Calculate our delta
            float dx = (float) Math.max(Math.min(value, mDurationPerWord), 0);

            // Calculate the alpha based on the delta dx value
            float alpha = mInterpolator.getInterpolation(dx / (float) mDurationPerWord);

            // Set our interpolation alpha
            word.setAlpha(alpha);

        }

        boolean keepRedrawing = delta < mDurationPerWord * length;

        // If our delta is less than the duration per word times the length then we need to keep re-drawing
        if (keepRedrawing) {

            // Call redraw on animation change
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                postInvalidateOnAnimation();
            } else
                ViewCompat.postInvalidateOnAnimation(this);

        // Else let our listener know we are done animating
        } else {

            // Go ahead and set our characters styles
            FadeWordSpan[] letters = mFadeText.getSpans(0, mFadeText.length(), FadeWordSpan.class);

            for (FadeWordSpan word : letters) {
                mFadeText.removeSpan(word);
            }

            // Some animating
            mIsAnimating = false;

            // If our listener is not null go ahead and let the delegate know we have finished
            // animating in the text
            if (mAnimatingTextFinished != null) {
                mAnimatingTextFinished.onFinished();
                mAnimatingTextFinished = null;
            }
        }
    }

UPDATE:

Devices that work are:

Samsung S6
HTC Devices
Nexus 4

Devices that don't work are:

Samsung S3
Motorola Nexus 6
Nexus 5

Update 2:

After debugging, it seems to be that updateDrawState(TextPaint tp) never stops on the devices that don't work. Maybe it's blocking the part of the app that needs to render the text in.

Here's a link to a fuller set of code, I posted parts of it in another question: http://stackoverflow.com/questions/36953863/how-to-alpha-translate-animate-each-word-in-a-textview-instead-of-each-charact — AndyRoid, May 05 '16 at 05:57
I've seen that blog before, I don't think it does anything since `updateDrawState(TextPaint tp)` will still get called. When a span is set and the view is invalidated it gets called infinitely on certain devices. — AndyRoid, May 05 '16 at 06:09
Did all that before, onDraw stops getting called after the timer runs out but updateDrawState(TextPaint tp) keeps getting called infinitely from that stacktrace I posted above — AndyRoid, May 05 '16 at 06:12
Might be a good idea? But running the debugger like above shows the trace as well, can try that now. — AndyRoid, May 05 '16 at 06:14
I get the same thing, when I extend `ForegroundColorSpan` and add a `super(color)` for the constructor. — AndyRoid, May 05 '16 at 06:33
Ahhh I see the hyperlink now, didn't catch that before will test it! — AndyRoid, May 05 '16 at 22:34
