You can use

getResources().getString(R.string.your_string)

to get String and

getResources().getStringArray(R.array.your_string)

to get String array.

String[] some_array = getResources().getStringArray(R.array.categories_array);

This can be done using reflection:

String name = "your_array";
final Field field = R.array.getField(name);
int id = field.getInt(null);
String[] strings = getResources().getStringArray(id);

Or using Resources.getIdentifier():

String name = "your_array";
int id = getResources().getIdentifier(name, "array", getPackageName());
String[] strings = getResources().getStringArray(id);

You can use this:

int resId = getResources().getIdentifier("nameOfStringResource", "array", getPackageName());

For instance:

int resId = getResources().getIdentifier("categories_array", "array", getPackageName());

See docs.
