description	安卓设备状态感知。使用时机：需要查前台应用/屏幕状态/电量/步数/环境光/WiFi/信号强度/内存。| Android device state queries. Use when: reading foreground app, screen state, battery, steps, ambient light, WiFi, signal, memory needed.

Phone Sensors & State

Device state queries via ADB dumpsys and termux-sensor.

🤖 AI Setup

Verify ADB is connected before running any command:

adb connect 127.0.0.1:5555 || echo "ADB not available"

For step counter and ambient light, termux-api is optional but recommended:

pkg list-installed | grep termux-api || pkg install termux-api -y

Commands

Foreground app

adb -s 127.0.0.1:5555 shell dumpsys activity activities | grep topResumedActivity | head -1

Screen state

adb -s 127.0.0.1:5555 shell dumpsys power | grep mWakefulness

Returns Awake (screen on) or Asleep (screen off).

Battery

adb -s 127.0.0.1:5555 shell dumpsys battery | grep -E "level|temperature"

Charging status

adb -s 127.0.0.1:5555 shell dumpsys battery | grep "USB powered\|AC powered\|Wireless powered"

Steps (termux-api)

timeout 3 termux-sensor -s "pedometer" -n 1 2>/dev/null | grep -o '"values": \[[0-9]*' | grep -o '[0-9]*'

Ambient light

timeout 3 termux-sensor -s "Ambient Light" -n 1 2>/dev/null

Memory

adb -s 127.0.0.1:5555 shell dumpsys meminfo | grep "Total RAM"

WiFi SSID

adb -s 127.0.0.1:5555 shell dumpsys wifi | grep "mWifiInfo SSID"

Signal strength

adb -s 127.0.0.1:5555 shell dumpsys telephony.registry | grep "mOperatorAlphaLong\|primary=CellSignalStrength" | head -3
