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
