ADB 命令

1、查看MAC地址：adb shell cat /sys/class/net/wlan0/address
2、CPU信息：adb shell cat /proc/cpuinfo
3、查看wifi密码：adb shell cat /data/misc/wifi/*.conf
4、通过wifi连接adb: adb connect 172.27.96.5:5555

5、恢复出厂设置：adb shell am broadcast -a android.intent.action.MASTER_CLEAR
需要先adb root
android 8.0版本后改为：adb shell am broadcast -a android.intent.action.FACTORY_RESET android

8、adb授权过程：

• 执行adb shell后，adb.exe会将当前PC的公钥(或者公钥的hash值之类的fingerprint)发送给android设备，公钥保存在~/.android/目录中的adbkey与adbkey.pub
• 如果android已经保存了PC的公钥，则能成功匹配，进行认证，建立adb连接
• 如果android没有保存PC的公钥，则弹出提示框提示是否允许这台机器进行adb连接，当点击了允许授权之后，android就会保存这台PC的adbkey.pub公钥，目录为/data/misc/adb/adb_keys

9、通过包名查看apk文件的位置：adb shell pm path com.zsg.launcher
输出：package:/system/app/Launcher.apk

10、状态栏、导航栏控制

• 全隐藏：adb shell settings put global policy_control immersive.full=*
• 隐藏状态栏：adb shell settings put global policy_control immersive.status=*
• 隐藏导航栏：adb shell settings put global policy_control immersive.navigation=*
• 单独控制app不隐藏，设置com.zsg.test不隐藏，其他程序隐藏：
  adb shell settings put global policy_control immersive.full=apps,-com.zsg.test
• 恢复正常模式：adb shell settings put global policy_control null

11、获取当前设备支持的features。Get Android System Available Features

adb shell pm list features:

feature:android.hardware.nfc
feature:android.hardware.nfc.any
feature:android.hardware.nfc.hce
feature:android.hardware.nfc.hcef
feature:android.hardware.bluetooth_le
feature:android.hardware.camera
feature:android.hardware.camera.any
feature:android.hardware.camera.front
feature:android.hardware.faketouch
feature:android.hardware.location
feature:android.hardware.location.network
feature:android.hardware.microphone
feature:android.hardware.sensor.light
feature:android.hardware.sensor.proximity
feature:android.hardware.sensor.stepcounter
feature:android.hardware.sensor.stepdetector
feature:android.hardware.touchscreen
feature:android.hardware.usb.accessory
feature:android.hardware.usb.host
feature:android.hardware.wifi
feature:android.hardware.wifi.direct
feature:android.software.activities_on_secondary_displays
feature:android.software.adoptable_storage
feature:android.software.app_widgets
feature:android.software.autofill
feature:android.software.backup
feature:android.software.cts
feature:android.software.device_id_attestation
feature:android.software.webview

//使用系统接口获取：
FeatureInfo[] features = getPackageManager().getSystemAvailableFeatures();

boolean b = getPackageManager().hasSystemFeature(featureName)
boolean hasCamera = pm.hsaSystemFeature(PackageManager.FEATURE_CAMERA); //是否支持相机
boolean b = getPackageManager().hasSystemFeature(PackageManager.FEATURE_WATCH)
