| * <p>BatteryService monitors the charging status, and charge level of the device |
| * battery. When these values change this service broadcasts the new values |
| * to all {@link android.content.BroadcastReceiver IntentReceivers} that are |
| * watching the {@link android.content.Intent#ACTION_BATTERY_CHANGED |
| * BATTERY_CHANGED} action.</p> |
| * <p>The new values are stored in the Intent data and can be retrieved by |
| * calling {@link android.content.Intent#getExtra Intent.getExtra} with the |
| * following keys:</p> |
| * <p>"scale" - int, the maximum value for the charge level</p> |
| * <p>"level" - int, charge level, from 0 through "scale" inclusive</p> |
| * <p>"status" - String, the current charging status.<br /> |
| * <p>"health" - String, the current battery health.<br /> |
| * <p>"present" - boolean, true if the battery is present<br /> |
| * <p>"icon-small" - int, suggested small icon to use for this state</p> |
| * <p>"plugged" - int, 0 if the device is not plugged in; 1 if plugged |
| * into an AC power adapter; 2 if plugged in via USB.</p> |
| * <p>"voltage" - int, current battery voltage in millivolts</p> |
| * <p>"temperature" - int, current battery temperature in tenths of |
| * a degree Centigrade</p> |
| * <p>"technology" - String, the type of battery installed, e.g. "Li-ion"</p> |
| * |
| * <p> |
| * The battery service may be called by the power manager while holding its locks so |
| * we take care to post all outcalls into the activity manager to a handler. |
| * |
| * FIXME: Ideally the power manager would perform all of its calls into the battery |
| * service asynchronously itself. |
