The following code (run in android) always gives me a ClassCastException in the 3rd line:
final String[] v1 = i18nCategory.translation.get(id);
final ArrayList<String> v2 = new ArrayList<String>(Arrays.asList(v1));
String[] v3 = (String[])v2.toArray();
This is because when you use
toArray() it returns an Object[], which can't be cast to a String[] (even tho the contents are Strings) This is because the toArray method only gets a
List and not
List<String>as generics are a source code only thing, and not available at runtime and so it can't determine what type of array to create.
use
toArray(new String[v2.size()]);which allocates the right kind of array (String[] and of the right size)
