linux下service的命令用法
一、用法概述：
# service
service
Usage: service [-h|-?]
service list
service check SERVICE
service call SERVICE CODE [i32 INT | s16 STR] [intent] ...
Options:
i32: Write the integer INT into the send parcel.
s16: Write the UTF-16 string STR into the send parcel.
intent: Write and Intent int the send parcel. ARGS can be/n"
action=STR data=STR type=STR launchFlags=INT component=STR categories=STR[,STR,...]/n
二、详解:
1. service list
会列出本机所有正在运行的service, 如：
Found 42 services:
0 phone: [com.android.internal.telephony.ITelephony]
1 iphonesubinfo: [com.android.internal.telephony.IPhoneSubInfo]
2 isms: [com.android.internal.telephony.gsm.ISms]
3 simphonebook: [com.android.internal.telephony.gsm.ISimPhoneBook]
4 appwidget: [com.android.internal.appwidget.IAppWidgetService]
5 audio: [android.media.IAudioService]
6 wallpaper: [android.app.IWallpaperService]
7 checkin: [android.os.ICheckinService]
8 search: [android.app.ISearchManager]
9 location: [android.location.ILocationManager]
10 devicestoragemonitor: []
11 mount: [android.os.IMountService]
12 notification: [android.app.INotificationManager]
13 connectivity: [android.net.IConnectivityManager]
14 wifi: [android.net.wifi.IWifiManager]
15 netstat: [android.os.INetStatService]
16 input_method: [com.android.internal.view.IInputMethodManager]
17 clipboard: [android.text.IClipboard]
18 statusbar: [android.app.IStatusBar]
19 window: [android.view.IWindowManager]
20 sensor: [android.hardware.ISensorService]
21 alarm: [android.app.IAlarmManager]
22 hardware: [android.os.IHardwareService]
23 battery: []
24 content: [android.content.IContentService]
25 permission: [android.os.IPermissionController]
26 activity.providers: []
27 activity.senders: []
28 activity.services: []
29 activity.broadcasts: []
30 cpuinfo: []
31 meminfo: []
32 activity: [android.app.IActivityManager]
33 package: [android.content.pm.IPackageManager]
34 telephony.registry: [com.android.internal.telephony.ITelephonyRegistry]
35 usagestats: [com.android.internal.app.IUsageStats]
36 batteryinfo: [com.android.internal.app.IBatteryStats]
37 power: [android.os.IPowerManager]
38 SurfaceFlinger: [android.ui.ISurfaceComposer]
39 media.camera: [android.hardware.ICameraService]
40 media.player: [android.hardware.IMediaPlayerService]
41 media.audio_flinger: [android.media.IAudioFlinger]
2、service check "service name" 检查service是否存在
如:
# service check phone
Service phone: found
# service check dd
Service dd: not found
3、service call "service name" code intent ....
service call SERVICE CODE [i32 INT | s16 STR] ...
i32: Write the integer INT into the send parcel.
s16: Write the UTF-16 string STR into the send parcel.
在网络上查找了一下使用adb命令来控制真机的横竖屏的命令，普遍找到的结果是：
adb shell service call window 2013 i32 0（设置横屏）
adb shell service call window 2013 i32 1（设置竖屏）
但是在真机（root过）上测试普遍没有通过，会有出错信息。（Result: Parcel(Error: 0xffffffb6 "Not a data message")）
SERVICE可从list中获取，CODE的获取方法（，CODE列表：），但是发现看到的不是很准确，（这个可以自己写个循环脚本试验一下）。i32代表数字，s16代表字符串。
本人找不到真正代表window横竖屏的CODE，所以写了个循环脚本，通过观察现象，找到了对应的CODE，那就是74。
adb shell service call window 74 i32 0（设置横屏）
adb shell service call window 74 i32 1（设置竖屏）
符上脚本代码：
#!bin/bash count=0 while [ "$count" -lt 1000 ]; do echo "$count" adb shell service call window "$count" i32 0 count=$(($count+1)) done
如：service call power 1
service call phone 2 s16 "10086"
