Country selection is not working.

Hi,

I have implemented the library which seems to be working fine, until today when I found that the country selector is not working without changing any respective code. If I choose any country from the list of countries, it does not change in the selector.
I also see error "D/CCP: updateFormattingTextWatcher: EditText not registered CCP_last_selection" in android logcats. Any idea on what could have gone wrong?

首先在 Android library 中复现国家选择，并检查报告的 logcat 消息“updateFormattingTextWatcher: EditText not registered CCP_last_selection”。跟踪 country selector 的更新和格式化流程，以确定所选国家为何没有变化。选择国家后，selector 能够在不出现此错误的情况下更新，即表示完成。
