error: Apostrophe not preceded by \ (in XXX.)

     string.xml里报了 error: Apostrophe not preceded by \ (in The user hasn't turned on yet and not allowed to checkout.)这样的错,这行代码是

<string name="message_noAllowCheckOut_notOnBoard">The userhasn't turned on yet and not allowed to checkout.</string>

橙色部分就是错误的源头，这个需要转义，在 '前加上“\”即可解决
