break;
case BatteryManager.BATTERY_STATUS_CHARGING:
statusString = "charging";
battery_image.setImageResource(R.drawable.stat_sys_battery_charge);
battery_image.getDrawable().setLevel(level);
break;
case BatteryManager.BATTERY_STATUS_DISCHARGING:
statusString = "discharging";
battery_image.setImageResource(R.drawable.stat_sys_battery);
battery_image.getDrawable().setLevel(level);
break;
case BatteryManager.BATTERY_STATUS_NOT_CHARGING:
statusString = "not charging";
break;
case BatteryManager.BATTERY_STATUS_FULL:
statusString = "full";
break;
