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;
kernel\msm-3.18\drivers\power\bq2570x\bq2570x_charger.c
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; }
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);
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:
usb powered : true
那么闪电图标应该会出现
status: 2
那么充电动画应该启动了
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
dumpsys battery set usb 1
闪电图标应该会出现
dumpsys battery set status 2
充电动画应该启动了
dumpsys battery set usb 0
闪电图标消失
dumpsys battery set status 4
充电动画消失
总结
以上所述是小编给大家介绍的android 开机充电图标和充电动画效果,希望对大家有所帮助
