提示：首先检查你的web浏览你的手机。如果这将是同样的情况 - 那么你不必担心。我有同样的情况，它发生时，仿真器没有权限净所有的时间。尝试在正常的设备。

Hint: First of all check your web browse in your phone. If it will be the same situation - then you have to worry about. I had the same situation and it happened all time when EMULATOR doesn't have permission to net. Try on normal device.
