shell/ batch scripting to direct commands to adb shell
提问by Harkish
I am trying to write a batch(for win) and a shell script for linux to automate key and touch events on a android UI. At the moment in a windows batch file I am starting a adb shell for each event for eg
我正在尝试为 linux 编写批处理（用于 win）和 shell 脚本，以在 android UI 上自动执行按键和触摸事件。目前在 Windows 批处理文件中，我正在为每个事件启动一个 adb shell，例如
:again
adb shell am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity
sleep 15
adb shell sendevent /dev/input/event0 3 0 281
adb shell sendevent /dev/input/event0 3 1 70
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0
sleep 5
adb shell input keyevent 82
adb shell input keyevent 20
adb shell input keyevent 20
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 66
sleep 5
goto again
The above code is infact starting a new adb shell each time. I want to avoid this. I want my batch script to start the adb shell only once and I would like to route the sendevent and other commands to the subshell, ie the adb shell.
上面的代码实际上每次都启动一个新的 adb shell。我想避免这种情况。我希望我的批处理脚本只启动一次 adb shell，我想将 sendevent 和其他命令路由到子 shell，即 adb shell。
Any idea how I can do this in win batch and Lin shell script?
知道如何在 win 批处理和 Lin shell 脚本中执行此操作吗？

I don't know much about batch scripting or shell scripting, but I was able to quickly write a java program to do this:
我对批处理脚本或 shell 脚本了解不多，但我能够快速编写一个 java 程序来执行此操作：
import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;
public class AndroidShell {
private ProcessBuilder builder;
private Process adb;
private static final byte[] LS = "\n".getBytes();
private OutputStream processInput;
private InputStream processOutput;
private Thread t;
/**
* Starts the shell
*/
public void start() throws IOException {
builder = new ProcessBuilder("adb", "shell");
adb = builder.start();
// reads from the process output
processInput = adb.getOutputStream();
// sends to process's input
processOutput = adb.getInputStream();
// thread that reads process's output and prints it to system.out
Thread t = new Thread() {
public void run() {
try {
int c = 0;
byte[] buffer = new byte[2048];
while((c = processOutput.read(buffer)) != -1) {
System.out.write(buffer, 0, c);
}
}catch(Exception e) {}
}
};
t.start();
}
/**
* Stop the shell;
*/
public void stop() {
try {
if(processOutput != null && t != null) {
this.execCommand("exit");
processOutput.close();
}
}catch(Exception ignore) {}
}
/**
* Executes a command on the shell
* @param adbCommand the command line.
* e.g. "am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity"
*/
public void execCommand(String adbCommand) throws IOException {
processInput.write(adbCommand.getBytes());
processInput.write(LS);
processInput.flush();
}
public static void main(String[] args) throws Exception {
AndroidShell shell = new AndroidShell();
shell.start();
for(String arg : args) {
if(arg.startsWith("sleep")) {
String sleep = arg.split(" ")[1].trim();
long sleepTime = Integer.parseInt(sleep) * 1000;
Thread.sleep(sleepTime);
}else {
shell.execCommand(arg);
}
}
shell.stop();
}
}
You can then use this class in a shell script as you like passing the commands to execute as command line arguments in your main method.
然后，您可以在 shell 脚本中使用此类，因为您喜欢传递命令以在 main 方法中作为命令行参数执行。
e.g. Below is the shell script:
例如下面是shell脚本：
#!/bin/bash
java AndroidShell "am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity" \
"sleep 15" \
"sendevent /dev/input/event0 3 0 281" \
"sendevent /dev/input/event0 3 1 70" \
"sendevent /dev/input/event0 1 330 1" \
"sendevent /dev/input/event0 0 0 0" \
"sleep 10" \
"sendevent /dev/input/event0 1 330 0" \
"exit"

Put all the commands you want to run at once in an external file, one per line, then run:
将您想一次运行的所有命令放在一个外部文件中，每行一个，然后运行：
adb shell < commands.txt

Topher's answer is almost correct.
Topher 的回答几乎是正确的。
Just remove the newlines and it will work.
只需删除换行符，它就会起作用。
adb shell "sendevent /dev/input/event9 3 53 215;sendevent /dev/input/event9 3 54 68;sendevent /dev/input/event9 3 48 40;sendevent /dev/input/event9 3 50 6;sendevent /dev/input/event9 3 57 0;sendevent /dev/input/event9 0 2 0;sendevent /dev/input/event9 0 0 0;sendevent /dev/input/event9 3 53 215;sendevent /dev/input/event9 3 54 68;sendevent /dev/input/event9 3 48 0;sendevent /dev/input/event9 3 50 6;sendevent /dev/input/event9 3 57 0;sendevent /dev/input/event9 0 2 0;sendevent /dev/input/event9 0 0 0;"
The only thing you need to take care of is, that you do not feed in more than 25 (that's the amount I used, 30 doesn work anymore) sendevents, because else adb will throw the error, that there are too many arguments or so.
你唯一需要注意的是，你不提供超过 25 个（这是我使用的数量，30 个不再工作）sendevents，因为否则 adb 会抛出错误，有太多的参数左右.

I am doing something similar
我正在做类似的事情
(
echo cd sdcard
echo ls
) | adb shell
So it may work as below:
所以它可能如下工作：
(
echo am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity
echo sleep 15
echo sendevent /dev/input/event0 3 0 281
echo sendevent /dev/input/event0 3 1 70
echo sendevent /dev/input/event0 1 330 1
echo sendevent /dev/input/event0 0 0 0
echo sendevent /dev/input/event0 1 330 0
echo sendevent /dev/input/event0 0 0 0
echo sendevent /dev/input/event0 1 330 1
echo sendevent /dev/input/event0 0 0 0
echo sendevent /dev/input/event0 1 330 0
echo sendevent /dev/input/event0 0 0 0
echo sendevent /dev/input/event0 0 0 0
echo sendevent /dev/input/event0 0 0 0
echo sleep 5
echo input keyevent 82
echo input keyevent 20
echo input keyevent 20
echo input keyevent 22
echo input keyevent 22
echo input keyevent 22
echo input keyevent 66
echo sleep 5
) | adb shell

Another way to go is the following:
另一种方法如下：
adb shell "sendevent /dev/input/event0 3 0 281;
sendevent /dev/input/event0 3 1 70;
sendevent /dev/input/event0 1 330 1;
sendevent /dev/input/event0 0 0 0;
sendevent /dev/input/event0 1 330 0;
sendevent /dev/input/event0 0 0 0;
sendevent /dev/input/event0 1 330 1;
sendevent /dev/input/event0 0 0 0;
sendevent /dev/input/event0 1 330 0;
sendevent /dev/input/event0 0 0 0;
sendevent /dev/input/event0 0 0 0;
sendevent /dev/input/event0 0 0 0"
