## am
|
||
### start
|
||
用`am start`來打開一個activity，例：
|
||
```
|
||
adb shell am start -S com.logitech.sentineliq/.MainActivity --es cameraId 0
|
||
```
|
||
其中`-S`是指先停止app再打開app。還有其他的命令如下：
|
||
```
|
||
-D: enable debugging
|
||
-W: wait for launch to complete
|
||
--start-profiler <FILE>: start profiler and send results to <FILE>
|
||
-P <FILE>: like above, but profiling stops when app goes idle
|
||
-R: repeat the activity launch <COUNT> times. Prior to each repeat,
|
||
the top activity will be finished.
|
||
-S: force stop the target app before starting the activity
|
||
--opengl-trace: enable tracing of OpenGL functions
|
||
```

||
## pm
|
||
### list packages
|
||
列出所有安裝的apk
|
||
```bash
|
||
adb shell pm list packages
|
||
```
|
||
|
||
只列出 user 自己安裝的 apk:
|
||
```bash
|
||
adb shell "pm list packages -3"
|
||
```
|
||
|
||
## Forward
|
||
ADB forward用來把PC端收到的TCP轉到Android去，這樣就可以透過USB ADB達到網路的功能。
|
||
例：
|
||
```
|
||
adb forward tcp:6100 tcp:7100
|
||
```
|
||
|
||
上述等於：
|
||
```
|
||
PC Android
|
||
http://127.0.0.1:6100 APP(port: 8080)
|
||
| |
|
||
| |
|
||
V----------> ADB(USB)----------->
|
||
|
||
```
|
||
|
||
Android端所回應的HTTP封包也會經由原路回來，但是如果Android端要發一個request的話，PC端就收不到了，必須經由[[ADB#Reverse]]才行。

|
||
|
||
## Reverse
|
||
ADB reverse用來監聽Android端收到的request，假設今天在Android APP上寫一個`http://127.0.0.1:8080/say/message`，並希望PC端可以收到的話，就可以用reverse來操作，例：
|
||
```
|
||
adb reverse tcp:8081 tcp:8080
|
||
```
|
||
也就是說Android那邊發過來的封包會送交給PC這邊的port 8081。因此，PC端還需要寫一個Server來監聽8081才行。
