问题


I'm just wondering if is there any possibility to obtain battery status in broadcast receiver class that fires on ACTION_POWER_CONNECTED? Documentation suggest not, but it is always worth to ask :)

Cheers Ray


回答1:


Call registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)). The Intent that is returned is the last-broadcast ACTION_BATTERY_CHANGED broadcast, which has your battery status in its extras (see BatteryManager for the keys).

If you determine that you are calling it too soon, that ACTION_POWER_CONNECTED is invoked before ACTION_BATTERY_CHANGED gets updated, perhaps use AlarmManager to schedule yourself to wake up again in a few seconds, and check again then.
