Android 开机充电图标和充电动画

1. 首先驱动需要先获取到2个power supply

motg->usb_psy.name = "usb";

motg->usb_psy.type = POWER_SUPPLY_TYPE_USB;

motg->usb_psy.supplied_to = otg_pm_power_supplied_to;

motg->usb_psy.num_supplicants = ARRAY_SIZE(otg_pm_power_supplied_to);

motg->usb_psy.properties = otg_pm_power_props_usb;

motg->usb_psy.num_properties = ARRAY_SIZE(otg_pm_power_props_usb);

motg->usb_psy.get_property = otg_power_get_property_usb;

motg->usb_psy.set_property = otg_power_set_property_usb;

motg->usb_psy.property_is_writeable

	= otg_power_property_is_writeable_usb;

if (!msm_otg_register_power_supply(pdev, motg))

	psy = &motg->usb_psy;

	usb_psy = power_supply_get_by_name("usb");

static int bq2570x_psy_register(struct bq2570x *bq)

{

	int ret;

	bq->batt_psy.name = "dc_o2";

	bq->batt_psy.type = POWER_SUPPLY_TYPE_BATTERY;

	bq->batt_psy.properties = bq2570x_charger_props;

	bq->batt_psy.num_properties = ARRAY_SIZE(bq2570x_charger_props);

	bq->batt_psy.get_property = bq2570x_charger_get_property;

	bq->batt_psy.set_property = bq2570x_charger_set_property;

	bq->batt_psy.external_power_changed = bq2570x_external_power_changed;

	bq->batt_psy.property_is_writeable = bq2570x_charger_is_writeable;

	ret = power_supply_register(bq->dev, &bq->batt_psy);

	if (ret < 0) {

		pr_err("failed to register batt_psy:%d\n", ret);

		return ret;

	}

	return 0;

}

1. 充电的闪电图标和充电动画启动逻辑

闪电图标启动逻辑：POWER_SUPPLY_TYPE_USB的power supply上报USB类型(CDP,DCP,USB)

power_supply_set_supply_type(bq->usb_psy, POWER_SUPPLY_TYPE_USB);

ret = power_supply_set_online(bq->usb_psy, true);

power_supply_changed(bq->usb_psy);

充电动画的启动逻辑：POWER_SUPPLY_TYPE_BATTERY的power supply上报充电状态(CHARGE_STATE_NOT_CHARGING，CHARGE_STATE_FASTCHARGE)

bq->charge_state = CHARGE_STATE_FASTCHARGE;

power_supply_changed(&bq->batt_psy);

1. 利用dumpsys分析当前battery 状态

V2_PRO:/ # dumpsys battery

Current Battery Service state:

  AC powered: false

  USB powered: true

  Wireless powered: false

  Max charging current: 0

  Max charging voltage: 0

  Charge counter: 0

  status: 2

  health: 2

  present: true

  level: 46

  scale: 100

  voltage: 7

  temperature: 270

  technology: Li-ion

如上主要关注2个字段：

那么闪电图标应该会出现

同时我们还可以通过shell指令的方式启动充电图标和充电动画

闪电图标应该会出现

充电动画应该启动了

闪电图标消失

充电动画消失
