TextInputLayout: RuntimeException - Failed to resolve attribute at index 24
Just change the base theme for TextLabel to Widget.Design.TextInputLayout
<style name="TextLabel" parent="Widget.Design.TextInputLayout">
For me a following works (https://stackoverflow.com/a/42779409/2914140):
<!-- Base application theme. --><style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- Customize your theme here. --> <item name="textColorError">@color/design_textinput_error_color_light</item></style>
