Java Android无法实例化UUID.fromString上的活动

我正在尝试使用以下UUID为android上的蓝牙应用程序创建Rfcomm：-

private UUID myUUID=UUID.fromString（“00001101-0000‌​-1000-8000-00805F9B34FB”）

这是我的MainActivity.java

错误是

 Caused by: java.lang.NumberFormatException: Invalid long: "0000‌​"

很可能您使用的UUID是错误的。请检查一下。
我登记了

而且它也显示无效

附言：我会加上它作为评论，但少了点
