// (target SDK <= 15 (Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)), or for digits.
// When talking to new applications we never use this method because it's inherently
// racy and has unpredictable results, but for backward compatibility we continue
// sending the key events for only Enter and Backspace because some applications
// mistakenly catch them to do some stuff.
