Hi guys am new to the shell scripting.. please do not mind if acted like a noob.
The following error keeps poping up when am trying to run the shell script on my android device
#!/bin/bash
for i in $(seq 100)
do
echo "Time: $i"
adb -s $* shell am start com.android.camera/.Camera -W -S
adb -s $* shell sleep 3
adb -s $* shell input tap 540 1994
adb -s $* shell input tap 540 1994
adb -s $* shell input tap 540 1994
count=`adb -s $* shell ls /sdcard/DCIM/Camera/ | wc |awk '{print $1}'`
echo Count: $count
if [[ count -gt 500 ]]; then
break
fi
adb -s $* reboot
adb -s $* wait-for-device
adb -s $* shell sleep 40
adb -s $* shell input tap 500 1200
done
Result:
adb.exe: unknown command am
adb.exe: unknown command sleep
you can't run adb commands on your android device. instead the adb binary must installed on host. the script is a linux script and can not run from windows. prepare bootable usb flash drive and run this script from any linux terminal
furthermore some of your commands requires root permissions. therefore sush must invited (and permissions granted on superuser app on touchscreen)
adb shell su -c "am start com.android.camera/.Camera -W -S"
awk is not available on android. to make it more clear that these pipes are actually running on host, quote the android commands (or even better avoid awk at all)
count=$(adb shell "ls -1 /sdcard/DCIM/Camera" | wc | awk '{print $1}')
count=$(adb shell "ls -1 /sdcard/DCIM/Camera | wc -l")
am is actually a shell script pointing to am.jar this requires full booted android. if you try to run in recovery mode you should at least run the framework
I am trying to simply count the number of files in a directory on an Android device. I am using adb shell via a Windows10 command prompt. Utilities like find, wc, tree and tail do not seem to work e.g:
`tree . | tail -1`
gives
`tmp-mksh: tree: not found`
`tmp-mksh: tail: not found`
I could write some java to do it but that would just be silly :) Any ideas?
Hey I had the same issue and I decide to use powershell instead of cmd.
you can get the count of the files in a directory with this:
$counter = $(adb shell 'ls sdcard/DCIM/Camera | wc -l') -as [int]
this will not apply to the folders inside, for that I thing you can get the folders using:
adb shell 'ls -d sdcard/DCIM/*/'
and then do a for loop with those routes ?
foreach ($folder in $(adb shell 'ls -d sdcard/DCIM/*/'))
{
$counter = $counter + $(adb shell 'ls sdcard/DCIM/Camera | wc -l') -as [int]
}
let me know how it goes,
have a great weekend!
Try the following:
$ adb shell
generic_x86:/ $ cd yourDirectory
generic_x86:/yourDirectory $ ls | wc -l
For example, in an emulator:
$ adb shell
generic_x86:/ $ cd sdcard
generic_x86:/sdcard $ ls | wc -l
10
EDIT:
For a device you can try:
$ adb shell
generic_x86:/ $ cd yourDirectory
generic_x86:/yourDirectory $ ls -l | grep . -c
I am trying to automate some of the test cases where in i need to connect to multiple devices , most of the time adb connects to only one device . For that every time i used to kill-server and start-server manually but when i execute adb devices command , its listing both of the devices . Can anyone tell me step by step how to usb connect multiple android devices with adb on windows 7 , so that i need not restart the adb server .
adb devices lists both the devices as below :
C:\Users>%ANDROID_SDK_HOME%\adb devices
List of devices attached
0123456789ABCDEF device
0123456789ABCD device
adb rarely connects to both devices , how to make it connect to both the devices simultaneously
You can use adb devices to get a list of connected devices and then run adb -s DEVICE_SERIAL_NUM install... for every device listed.
Something like (bash):
adb devices | tail -n +3 | cut -sf 1 -d " " | xargs -iX adb -s X install ...
Comments suggest this might work better for newer versions:
adb devices | tail -n +2 | cut -sf 1 | xargs -iX adb -s X install ...
if you get any error then try this also adb devices | tail -n +2 | cut -sf 1 | xargs -iX adb -s X install -r *.apk
$ adb --help
-s SERIAL use device with given serial (overrides $ANDROID_SERIAL)
$ adb devices
List of devices attached
emulator-5554 device
7f1c864e device
$ adb shell -s 7f1c864e
error: more than one device and emulator
Use the -s option BEFORE the command to specify the device, for example:
adb -s 7f1c864e shell
For multiple Emulator, use the process's IP and port as the id, like:
adb -s 192.168.232.2:5555 <command>
See How to get the Android Emulator's IP address?
But if there is only a single Emulator, try:
adb -e <command>
See also http://developer.android.com/tools/help/adb.html#directingcommands
adb -d shell (or adb -e shell).
This command will help you in most of the cases, if you are too lazy to type the full ID.
From http://developer.android.com/tools/help/adb.html#commandsummary:
-d - Direct an adb command to the only attached USB device. Returns an error when more than one USB device is attached.
-e - Direct an adb command to the only running emulator. Returns an error when more than one emulator is running.
Another alternative would be to set environment variable ANDROID_SERIAL to the relevant serial, here assuming you are using Windows:
set ANDROID_SERIAL=7f1c864e
echo %ANDROID_SERIAL%
"7f1c864e"
Then you can use adb.exe shell without any issues.
To install an apk on one of your emulators:
First get the list of devices:
-> adb devices
List of devices attached
25sdfsfb3801745eg device
emulator-0954 device
Then install the apk on your emulator with the -s flag:
-> adb -s "25sdfsfb3801745eg" install "C:\Users\joel.joel\Downloads\release.apk"
Performing Streamed Install
Success
Ps.: the order here matters, so -s <id> has to come before install command, otherwise it won't work.
Hope this helps someone!
I found this question after seeing the 'more than one device' error, with 2 offline phones showing:
C:\Program Files (x86)\Android\android-sdk\android-tools>adb devices
List of devices attached
SH436WM01785 offline
SH436WM01785 offline
SH436WM01785 sideload
If you only have one device connected, run the following commands to get rid of the offline connections:
adb kill-server
adb devices
The best way to run shell on any particular device is to use:
adb -s << emulator UDID >> shell
For Example:
adb -s emulator-5554 shell
As per https://developer.android.com/studio/command-line/adb#directingcommands
What worked for my testing:
UBUNTU BASH TERMINAL:
$ adb devices
List of devices attached
646269f0 device
8a928c2 device
$ export ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL
646269f0
$ adb reboot bootloader
WINDOWS COMMAND PROMPT:
$ adb devices
List of devices attached
646269f0 device
8a928c2 device
$ set ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL$
646269f0
$ adb reboot bootloader
This enables you to use normal commands and scripts as if there was only the ANDROID_SERIAL device attached.
Alternatively, you can mention the device serial every time.
$ adb -s 646269f0 shell
This gist will do most of the work for you showing a menu when there are multiple devices connected:
$ adb $(android-select-device) shell
1) 02783201431feeee device 3) emulator-5554
2) 3832380FA5F30000 device 4) emulator-5556
Select the device to use, <Q> to quit:
To avoid typing you can just create an alias that included the device selection as explained here.
User #janot has already mentioned this above, but this took me some time to filter the best solution.
There are two Broad use cases:
1) 2 hardware are connected, first is emulator and other is a Device.
Solution : adb -e shell....whatever-command for emulator and adb -d shell....whatever-command for device.
2) n number of devices are connected (all emulators or Phones/Tablets) via USB/ADB-WiFi:
Solution:
Step1) run adb devices THis will give you list of devices currently connected (via USB or ADBoverWiFI)
Step2) now run adb -s <device-id/IP-address> shell....whatever-command
no matter how many devices you have.
Example to clear app data on a device connected on wifi ADB I would execute:
adb -s 172.16.34.89:5555 shell pm clear com.package-id
to clear app data connected on my usb connected device I would execute:
adb -s 5210d21be2a5643d shell pm clear com.package-id
For Windows, here's a quick 1 liner example of how to install a file..on multiple devices
FOR /F "skip=1" %x IN ('adb devices') DO start adb -s %x install -r myandroidapp.apk
If you plan on including this in a batch file, replace %x with %%x, as below
FOR /F "skip=1" %%x IN ('adb devices') DO start adb -s %%x install -r myandroidapp.apk
Create a Bash (tools.sh) to select a serial from devices (or emulator):
clear;
echo "====================================================================================================";
echo " ADB DEVICES";
echo "====================================================================================================";
echo "";
adb_devices=( $(adb devices | grep -v devices | grep device | cut -f 1)#$(adb devices | grep -v devices | grep device | cut -f 2) );
if [ $((${#adb_devices[#]})) -eq "1" ] && [ "${adb_devices[0]}" == "#" ]
then
echo "No device found";
echo "";
echo "====================================================================================================";
device=""
// Call Main Menu function fxMenu;
else
read -p "$(
f=0
for dev in "${adb_devices[#]}"; do
nm="$(echo ${dev} | cut -f1 -d#)";
tp="$(echo ${dev} | cut -f2 -d#)";
echo " $((++f)). ${nm} [${tp}]";
done
echo "";
echo " 0. Quit"
echo "";
echo "====================================================================================================";
echo "";
echo ' Please select a device: '
)" selection
error="You think it's over just because I am dead. It's not over. The games have just begun.";
// Call Validation Numbers fxValidationNumberMenu ${#adb_devices[#]} ${selection} "${error}"
case "${selection}" in
0)
// Call Main Menu function fxMenu;
*)
device="$(echo ${adb_devices[$((selection-1))]} | cut -f1 -d#)";
// Call Main Menu function fxMenu;
esac
fi
Then in another option can use adb -s (global option -s use device with given serial number that overrides $ANDROID_SERIAL):
adb -s ${device} <command>
I tested this code on MacOS terminal, but I think it can be used on windows across Git Bash Terminal.
Also remember configure environmental variables and Android SDK paths on .bash_profile file:
export ANDROID_HOME="/usr/local/opt/android-sdk/"
export PATH="$ANDROID_HOME/platform-tools:$PATH"
export PATH="$ANDROID_HOME/tools:$PATH"
Running adb commands on all connected devices
Create a bash (adb+)
adb devices | while read line
do
if [ ! "$line" = "" ] && [ `echo $line | awk '{print $2}'` = "device" ]
then
device=`echo $line | awk '{print $1}'`
echo "$device $# ..."
adb -s $device $#
fi
done
use it with
adb+ //+ command
you can use this to connect your specific device :
* adb devices
--------------
List of devices attached
9f91cc67 offline
emulator-5558 device
example i want to connect to the first device "9f91cc67"
* adb -s 9f91cc67 tcpip 8080
---------------------------
restarting in TCP mode port: 8080
then
* adb -s 9f91cc67 connect 192.168.1.44:8080
----------------------------------------
connected to 192.168.1.44:8080
maybe this help someone
Here's a shell script I made for myself:
#! /bin/sh
for device in `adb devices | awk '{print $1}'`; do
if [ ! "$device" = "" ] && [ ! "$device" = "List" ]
then
echo " "
echo "adb -s $device $#"
echo "------------------------------------------------------"
adb -s $device $#
fi
done
For the sake of convenience, one can create run configurations, which set the ANDROID_SERIAL:
Where the adb_wifi.bat may look alike (only positional argument %1% and "$1" may differ):
adb tcpip 5555
adb connect %1%:5555
The advance is, that adb will pick up the current ANDROID_SERIAL.
In shell script also ANDROID_SERIAL=xyz adb shell should work.
This statement is not necessarily wrong:
-s SERIAL use device with given serial (overrides $ANDROID_SERIAL)
But one can as well just change the ANDROID_SERIAL right before running the adb command.
One can even set eg. ANDROID_SERIAL=192.168.2.60:5555 to define the destination IP for adb.
This also permits to run adb shell, with the command being passed as "script parameters".
How can I run logcat on multiple devices at the same time? "adb logcat" command gives an error:
error: more than one device and emulator
Use the -s option of adb:
adb -s <serialnumber>
Example
C:\Users\lel>adb devices
List of devices attached
192.168.198.101:5555 device
0123456789ABCDEF device
adb -s 0123456789ABCDEF logcat
adb -s 192.168.198.101:5555 logcat
You can combine grep whit this, to get all lines that contain it.
an example is with System.out
Example:
adb -s 192.168.198.101:5555 logcat | grep "System.out"
I thought it might be useful. I have this script that helps me a lot. It logcats each device to a different file. To stop logging just press CTRL+C.
#! /bin/bash
devices=`adb devices | grep 'device$' | cut -f1`
pids=""
for device in $devices
do
log_file="$device-`date +%d-%m-%H:%M:%S`.log"
echo "Logging device $device to \"$log_file\""
adb -s $device logcat -v threadtime > $log_file &
pids="$pids $!"
done
echo "Children PIDs: $pids"
killemall()
{
echo "Killing children (what a shame...)"
for pid in $pids
do
echo "Killing $pid"
kill -TERM $pid
done
}
trap killemall INT
wait
Use your device ip:
adb -s device_ip:5555
