private static final int[][] icons_set = { tiles_fruits, tiles_foods }; and here geticonsset method
public int geticonsset() { return getprefs().getint(pref_icons_set, icons_set_fruits); } complete code here
you java.lang.arrayindexoutofboundsexception: length=2; index=3
because int set = preferencesservice.instance().geticonsset(); returns 3 array icons_set has 2 arguments.
you make sure array has enough elements.
