Use parseColor instead of getHTMLColor

getHTMLColor is not aware of ARGB color format which is commonly used in
android xml files. This causes problem with coloring spans in resources.

Instead of above it should be changed to parseColor() with supported
formats: #RRGGBB #AARRGGBB

Fix error overwriting when restoring error

onRestoreInstanceState restores the old error, after layout has been
done. A new error may have been set before this is done, which thus
overwrites the new error.

This patch prevents the new error from being overwritten.
