[Android开发学习32]BroadcastReceiver之电源管理

直接上代码:

                    //电池状态，返回是一个数字
                    // BatteryManager.BATTERY_STATUS_CHARGING 表示是充电状态
                    // BatteryManager.BATTERY_STATUS_DISCHARGING 放电中
                    // BatteryManager.BATTERY_STATUS_NOT_CHARGING 未充电

            }

        };
