shell/ batch scripting to direct commands to adb shell

Question

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 ad

Answer 1

Another way to go is the following:

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"

Put all the commands you want to run at once in an external file, one per line, then run:

adb shell < commands.txt

Answer 3

Topher's answer is almost correct.

Just remove the newlines and it will work.

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.

I am doing something similar

(
   echo cd sdcard
   echo ls
) | adb shell

So it may work as below:

(
    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

Answer 5

I don't know much about batch scripting or shell scripting, but I was able to quickly write a java program to do this:

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.

e.g. Below is the shell script:

#!/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"
