Отговори:

Във функцията android.view.ViewGroup.dispatchHoverEvent, има масив. Нека го наречем foo.

foo.length е 12.

Но някой е написал, в ред 1833, foo[n] за n 12.

Това вече е разрешено, тъй като за масив с дължина 12. n трябва да бъде между 0 и 11 включително. Това, между другото, е извънредно често срещана грешка.

Надявам се това да е от полза. Ако нещо, то показва колко полезни са следите от стека.
