When clearing error text in TextInputLayout, EditText background color turns black instead of return to its default color.

To reproduce:

final EditText editText = (EditText)findViewById(...);
editText.addTextChangedListener(new TextWatcher()
{
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after)
        { }
       
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count)
        { }

        @Override
        public void afterTextChanged(Editable s)
        {
                TextInputLayout textInputLayout = (TextInputLayout)editText .getParent();
               
                if(s.length() == 0)
                        textInputLayout.setError("Invalid text input!");
                else
                        textInputLayout.setError(null);
        }
});

The bug lies in:

TextInputLayout.updateEditTextBackground() private method where you clear EditText's background color filter instead of returning to its default one.

To fix this:

You need to remember the ColorFilter that was set on EditText background before setting error text (thus before setting red color filter).
