DrawableCompat.unwrap is not working pre Lollipop

Question

I'm using DrawableCompat.wrap to set tint on drawables in pre Lollipop and it's working fine. DrawableCompat.unwrap is not working pre Lollipop. I can't get the original drawable before the tint.

For example:

 if (v.isSelected()){
                Drawable normalDrawable = getResources().getDrawable(R.drawable.sample);
                Drawable wrapDrawable = DrawableCompat.wrap(normalDrawable);
                DrawableCompat.setTint(wrapDrawable, getResources().getColor(R.color.sample_color));
                imageButton.setImageDrawable(wrapDrawable);
 }else{
                Drawable normalDrawable = imageButton.getDrawable();
                Drawable unwrapDrawable = DrawableCompat.unwrap(normalDrawable);
                imageButton.setImageDrawable(unwrapDrawable);
 }

In pre lollipop devices DrawableCompact.unwrap returns the drawable with the tint and not the original one

@chrisonline Nothing new. We aren't using this functionality because of this behaviour, which is unfortunate because it is a strong tool. — user1787773, Aug 13 '15 at 10:30

If you want to clear the tint, call DrawableCompat.setTintList(drawable, null).

Unwrap isn't a destructive function, it's only there for you to get access to the original Drawable.

The following is an example code:

Drawable drawable = (Drawable) ContextCompat.getDrawable(getContext(), R.drawable.google_image);
if (condition) {
    drawable = DrawableCompat.wrap(drawable);
    DrawableCompat.setTint(drawable, ContextCompat.getColor(getContext(), R.color.grey700));
    DrawableCompat.setTintMode(drawable, PorterDuff.Mode.SCREEN);
    mImageView.setImageDrawable(drawable);
} else {
    drawable = DrawableCompat.unwrap(drawable);
    DrawableCompat.setTintList(drawable, null);
    mLoginStatusGoogleImageView.setImageDrawable(drawable);
}

In your case the code should be:

if (v.isSelected()) {
    Drawable normalDrawable = getResources().getDrawable(R.drawable.sample);
    Drawable wrapDrawable = DrawableCompat.wrap(normalDrawable);
    DrawableCompat.setTint(wrapDrawable, ContextCompat.getColor(getContext(), R.color.sample_color));
    DrawableCompat.setTint(wrapDrawable, getResources().getColor(R.color.sample_color));
    imageButton.setImageDrawable(wrapDrawable);
} else {
    Drawable normalDrawable = imageButton.getDrawable();
    Drawable unwrapDrawable = DrawableCompat.unwrap(normalDrawable);
    DrawableCompat.setTintList(unwrapDrawable, null);
    imageButton.setImageDrawable(unwrapDrawable);
}
