2,adb shell sendevent Debugging skills

KEY_VOLUMEUP Of down and up event ：
$ getevent
/dev/input/event2: 0001 0073 00000000  //  Hexadecimal 
/dev/input/event2: 0000 0000 00000000
/dev/input/event2: 0001 0073 00000001
/dev/input/event2: 0000 0000 00000000
 namely ：
$ getevent -l
/dev/input/event2: EV_KEY       KEY_VOLUMEUP         UP
/dev/input/event2: EV_SYN       SYN_REPORT           00000000
/dev/input/event2: EV_KEY       KEY_VOLUMEUP         DOWN
/dev/input/event2: EV_SYN       SYN_REPORT           00000000

KEY_VOLUMEUP Debug command ：
adb shell sendevent /dev/input/event2 1 115 0  //  Decimal system  DOWN  event 
adb shell sendevent /dev/input/event2 0 0 0    // SYNC  Report  DOWN  event 

adb shell sendevent /dev/input/event2 1 115 1  // UP  event 
adb shell sendevent /dev/input/event2 0 0 0    // SYNC  Report  UP  event 

KEY_VOLUMEDOWN Of down and up event ：
$ getevent
/dev/input/event2: 0001 0072 00000001
/dev/input/event2: 0000 0000 00000000
/dev/input/event2: 0001 0072 00000000
/dev/input/event2: 0000 0000 00000000
 namely ：
$ getevent -l
/dev/input/event2: EV_KEY       KEY_VOLUMEDOWN       DOWN
/dev/input/event2: EV_SYN       SYN_REPORT           00000000
/dev/input/event2: EV_KEY       KEY_VOLUMEDOWN       UP
/dev/input/event2: EV_SYN       SYN_REPORT           00000000

KEY_VOLUMEDOWN Debug command ：
adb shell sendevent /dev/input/event2 1 114 0  //  Decimal system  DOWN  event 
adb shell sendevent /dev/input/event2 0 0 0    // SYNC  Report  DOWN  event 

adb shell sendevent /dev/input/event2 1 114 1  // UP  event 
adb shell sendevent /dev/input/event2 0 0 0    // SYNC  Report  UP  event 

$ getevent // Can you tell which /dev/input/eventXXX Key event issued

3,adb shell sendevent Using examples

 You have to have Down event , To have Up event 
$ adb shell
$ su
// dev/input/event0  Corresponding to the power key Power event event //  Be sure to find event
// KEY_POWER,Power key  Down event 
# sendevent /dev/input/event0 1 116 1 && sendevent /dev/input/event0 0 0 0
// KEY_POWER,Power key  Up event 
# sendevent /dev/input/event0 1 116 0 && sendevent /dev/input/event0 0 0 0

// /dev/input/event2  The corresponding volume key Volume event event //  Be sure to find event
// KEY_VOLUMEUP, The volume + key  Down event 
# sendevent /dev/input/event2 1 115 1 && sendevent /dev/input/event2 0 0 0
// KEY_VOLUMEUP, The volume + key  Up event 
# sendevent /dev/input/event2 1 115 0 && sendevent /dev/input/event2 0 0 0

// KEY_VOLUMEDOWN, The volume - key  Down event 
# sendevent /dev/input/event2 1 114 1 && sendevent /dev/input/event2 0 0 0
// KEY_VOLUMEDOWN, The volume - key  Up event 
# sendevent /dev/input/event2 1 114 0 && sendevent /dev/input/event2 0 0 0
