PhoneNumberFormattingTextWatcher导致ANR

Question

当app ANR，死循环时出现奇怪的调用堆栈。没有与app本身相关的代码，PhoneNumberFormattingTextWatcher在堆栈中多次调用。有没有人遇到同样的问题？非常感谢提供的建议。 重现步骤：在消息传递应用程序的收件人区域中输入数字。

如果你在主线程上做了大量的操作，如果主线程被阻塞，那么主要叫做ANR。

试试这个会对你有帮助。

Thread t = new Thread(new Runnable() {
             @Override
             public void run() {

                 PhoneNumberFormatter.setPhoneNumberFormattingTextWatcher(thi‌​s, mRecipientsEditor);
             }
         });
        t.start();
