Converting CharSequence[] and CharSequence[]

view story

http://stackoverflow.com – I always thought CharSequence[] and String[] were essential the same, however : I have some code that has the following : CharSequence[] mEntries; ... String[] mEntriesString = (String[]) mEntries; ListAdapter adapter = new ArrayAdapter<String>(getContext(), R.layout.two_lines_list_preference_row, mEntriesString) When the code runs I get java.lang.ClassCastException: java.lang.CharSequence[] cannot be cast to java.lang.String[] So two questions ? why can this cast not happen why does the ArrayAdapter not allow for a CharSequence[] in it's constructor.
