TimerUtil 倒计时进入后台后无法持续执行

[xiejibiao]

TimerUtil 倒计时进入后台后无法持续执行，
操作步骤如下：
1）启动倒计时（60s）
2）最小化程序，进入后台，隔一小段时间后(两分钟)，重新返回APP
3）发现倒计时依旧未执行完毕

若Debug无法复现，请打release 包测试，release 复现率更高，IOS设备全部有此问题，安卓华为亦有此问题

源码TimerUtil.startCountDown()，进入后台，callback 停止后，mTotalTime 的值也不变了。再次进入前台，callback 继续回调，mTotalTime 的值才改变，需要改成int time = mTotalTime - timer.tick;
Timer 有个属性： tick。即使 callback 停止回调了，tick 也是在一直在累加的
或者调用TimerUtil.startTimer(), tick是一直累加，外面回调逻辑需要改成int time = mTotalTime - timer.tick
