ACTION_TIME_TICK
String ACTION_TIME_TICK
Broadcast Action: The current time has changed. Sent every minute. You cannot receive this through components declared in manifests, only by explicitly registering for it with [Context.registerReceiver()](https://developer.android.com/reference/android/content/Context.html#registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter))
.
This is a protected intent that can only be sent by the system.
Constant Value: "android.intent.action.TIME_TICK"
当前的系统时间发生改变时(以分钟计算),系统会广播这个Action事件,需要特别注意,你不能在manifests中注册该事件，这样会导致你无法接收到该广播信息，正确的做法是使用代码对该事件进行注册，详情请参见Context.registerReceiver()
