I want to save the screenshot created, in a specific folder on my PC.
cmd = 'adb shell screencap -p /sdcard/screen.png'
subprocess.Popen(cmd.split())
time.sleep(5)
cmd ='adb pull /sdcard/screen.png screen.png'
subprocess.Popen(cmd.split())
This works if I want the image in my workspace. But if I want to pull the screenshot in another folder, it doesn't work.
cmd ='adb pull /sdcard/screen.png C:\Users\xxx\Desktop\prova\screen.png'
subprocess.Popen(cmd.split())
if i run the command from cmd i have:

What can I do?
Always use double quotes("") for local paths. use it like this:
cmd = "adb pull /sdcard/screen.png \"C:\\Users\\xxx\\Desktop\\prova\\screen.png\"";
Don't write file name in destination path.
write in specific command like this:
adb pull
for example :
adb pull /sdcard/pictures c:/users/intel1/desktop/newfolder
This version worked for me
adb pull /sdcard/demo.mp4 "C:\Users\xxxxxxx\Desktop"
The one by #M D P did not as all those double dashes were unnecessary.

We have previously been using an emulator to run some of our tests on but now would like to use an actual Android device instead.
Part of our process is to make edits to the phones hosts file so we can send data to a different endpoint. To do this on an emulator we would launch like so with writeable access
emulator -avd Nexus_6_API_27 -noaudio -writable-system -no-snapshot-load -qemu &
and then run a shell script
sh hosts_override.sh
#!/bin/bash
external_ip="${EXTERNAL_HOST:-10.0.2.2}"
echo "Using external IP address $external_ip"
adb root
adb pull /system/etc/hosts /tmp/hosts
echo "$external_ip endpoint-1" >> /tmp/hosts
echo "$external_ip endpoint-2" >> /tmp/hosts
echo "$external_ip endpoint-3" >> /tmp/hosts
adb remount
adb push /tmp/hosts /system/etc
The problem we face at the moment is there seems to be no access to the phone (even though the phone has been rooted)
adbd cannot run as root in production builds
I can browse the files on the phone and see the hosts file
adb -s HT829GZ52000 shell
How do we get access so that we can write to the phone?
From a shell on my PC, I can run adb shell cmd package list packages, and get a list of all installed packages. I would like to run this and similar commands locally on my Android phone (Nexus 6P) in a terminal emulator (currently using Termux).
If I open the same shell with /system/bin/sh, and then try to run /system/bin/cmd package list packages, nothing happens (no errors, just outputs nothing and reloads the prompt).
If I run /system/bin/cmd -l the list of options appears as expected. $PATH and $LD_LIBRARY_PATH are the same in both environments. One major difference is that echo $USER returns "shell" from adb shell, but returns my local username from /system/bin/sh launched from Termux.
Is there any way to replicate the behavior of commands run from adb shell in a terminal emulator locally on Android?
Edit:
My device is rooted, and I am OK with root only solutions.
The problem is Termux. By design, Termux runs only (or is mostly?) the Linux command line programs that you install from within Termux using apt or the newer "native" package management interface, e.g. apt install bsdtar. What you need to run the adb shell commands is a terminal emulator that can truly access the underlying Android file system, not just the Termux that is practically a chroot save for the fact that it's aware it's not running commands from the filesystem root /.
As a simple test, run the following command:
which ls
It should return something like /system/bin/ls. But if it returns something like /data/data/com.termux/files/usr/bin/applets/ls then you have to change your terminal emulator to something else. I suspect that Termux was designed to take into account the more restrictive shell execution policies that Google put into place after KitKat or the Android 4.X.
The Android distribution I'm using, LineageOS 14.1, comes with a built-in shell emulator that allows me to run commands found in /system/bin/ls.
I don't have a rooted Nougat device handy, but something like the following may be a close enough approximation to adb shell (assuming you are using SuperSU):
env -i USER=shell "$(PATH=/system/xbin:/system/bin:/su/bin:/sbin:/magisk/.core/bin which su)" shell --context u:r:shell:s0 --shell /system/bin/sh --command COMMAND
I (very briefly) tested it from Termux on a rooted Marshmallow device.
To elaborate:
the -i flag is used to start with an empty environment
USER=shell isn't specifically required, but for some reason su refuses to run with a completely empty environment
$(PATH=/system/xbin:/system/bin:/su/bin:/sbin:/magisk/.core/bin which su) points to the full path of the su binary on your device and can be hardcoded if you prefer
shell instructs the su binary to login as the shell user (the same as adb shell)
--context u:r:shell:s0 sets the appropriate SELinux context
--shell /system/bin/sh instructs SuperSU to use the system shell rather than it's own sush shell
Another option would be to actually run adb from the device, connecting to itself over TCP. If you need some functionality that is only available via adb (e.g. in my case it was adb forward) then this may be your only option. Unfortunately this isn't particularly convenient.
I wasn't able to find success with any publicly available adb binaries, so I build it myself with a few minor changes. You can see the sources I used and the changes I made at https://github.com/shakalaca/fastboot-adb-android and https://github.com/brbsix/fastboot-adb-android, respectively.
Once you have adb installed, here's an abbreviated list of commands I used to connect to the device:
# Add iptables rules to block external connections to port 9999'
su root iptables -N adbd
su root iptables -A adbd -i lo -p tcp -m tcp --dport 9999 -j ACCEPT
su root iptables -A adbd -p tcp -m tcp --dport 9999 -j DROP
su root iptables -A INPUT -j adbd
# Necessary in order to display authorization prompt
su shell setprop ro.debuggable 1
su shell setprop service.adb.tcp.port 9999
su root start adbd
adb connect 127.0.0.1:9999
adb wait-for-local-device
To shut down:
adb kill-server
su root stop adbd
su shell setprop ro.debuggable 0
su shell setprop service.adb.tcp.port 0
su root iptables -D INPUT -j adbd
su root iptables -F adbd
su root iptables -X adbd
So I tried this recently...if you're rooted you can use a terminal emulator.
su
then the command you want without "adb shell" part of it.
i tried the command "adb shell dumpsys deviceidle force-idle" in order to force device into doze.
I did this on the device via terminal emulator as:
"dumpsys deviceidle force-idle" and it did take effect.
also the dumpsys batterystats command worked.
be careful with commands with extensive text output, as the screen will be flooded with the output and will be unresponsive for some time.
EDIT
I originally answered this without the termux tag in mind. This worked for me while trying to execute shell commands on a vanilla emulator and saw this question while researching, so I tried to answer it differently.
You almost had it there in your question. You only need to execute sh:
int result = -1;
try {
final Process shell = Runtime.getRuntime().exec("sh");
final DataOutputStream commands = new DataOutputStream(shell.getOutputStream());
commands.writeBytes("write a series");
commands.writeBytes("of commands here");
commands.writeBytes("exit\n");
commands.flush();
result = shell.waitFor();
}
} catch (Exception e) {
e.printStackTrace();
}
If result == 0 the commands were succesful, else otherwise
Only rooted android
Busybox must be installed (though you can try without it)
Just write the normal command without the prefix adb
Is there an adb command to put the device offline?I tried following but doesn't seem to work
COMMAND:-
adb devices offline
You can put a device in "offline" state by using push(or install) and reconnect commands:
1.push a file(or install a apk) to phone
adb -s [serial] push somefile /data/local/tmp
2.reconnect while push is still in progress
adb -s [serial] reconnect
SERIAL means serial number listed in the output of 'adb devices' command.
Repeat step 1 and 2, after a while, you can find this device is in offline state from output of "adb devices".
You can put this device in "device" state by using kill-server and start-server.
"reconnect" command is only supported by higher version of adb, 1.0.36 and later as far as I know.
How I can launch the ADB in Eclipse android?
[2014-03-16 16:13:43 - nadh] ------------------------------
[2014-03-16 16:13:43 - nadh] Android Launch!
[2014-03-16 16:13:43 - nadh] The connection to adb is down, and a severe error has occured.
[2014-03-16 16:13:43 - nadh] You must restart adb and Eclipse.
[2014-03-16 16:13:43 - nadh] Please ensure that adb is correctly located at 'C:\Program Files (x86)\adt-bundle-windows-x86_64-20131030_2\adt-bundle-windows-x86_64-20131030\sdk\platform-tools\adb.exe' and can be executed.
If you update to SDK 2.3 and you receive an error that looks like this:
“The connection to adb is down, and a severe error has occured.”
“Please ensure that adb is correctly located at ‘your_path\android-sdk-windows\tools\adb.exe’ and can
be executed.”
Solution is to add the path to SDK tools and platform tools in your classpath from Environment Variables. Then restart Eclipse.
To run ADB from eclipse you need an Eclipse command line window found here. Then, from Eclipse select run/external tools/ {the command prompt you added above }. Afterwards, type in adb on the console window.
This is the answer for what you asked, not a solution for your particular problem.

I'm trying to perform native code debug on my HTC Desire for my Android project.
The project is made of a thin layer of JNI wrapper and the main chunk in C++, compiled using ndk-build. The debuggable flag is set, I'm running 2.2 on an HTC Desire and I'm working with Ubuntu on my PC.
So a plain ndk-gdb --start returns a:
ERROR: Could not setup network redirection to gdbserver?
Maybe using --port=<port> to use a different TCP port might help?
This is weird. I checked on the internet and found that it's the wrong message error caused by a flaw in ndk-gdb. If I run ndk-gdb -- start --verbose I obtain this messed up error:

marco#pacer:~/dev/siege_game/trunk/SiegeGameNative$ run-as: Package 'com.marco83.siege' has corrupt installation
which, as you can see and as reported here: http://vilimpoc.org/blog/2010/09/23/hello-gdbserver-a-debuggable-jni-example-for-android/ is caused by a mix of different simultaneous outputs; the real error should be
Package 'xxxxx' has corrupt installation
Further investigation in this error pointed me to: http://osdir.com/ml/android-ndk/2010-08/msg00263.html
where the same error is reported, and they say it's not possible to debug natively on Desire. The problem is with run-as not being able to access the /data folder.
Any solution other than rooting/flashing the phone? Why does the run-as access /data?
I was thinking of a naive solution where I copy the package (objs, libs, ...) into an easier accessible location (like on the SDcard) and tell the debugger to access that location instead - is it feasible?
Thanks
Marco
EDIT: Update: I rooted the phone using unrevoked3. Even if I set chmod 0777 data (which is probably EXTREMELY dangerous), I get the same error. As reported in the second link in the post, run-as is checking if /data is accessible. How can I access run-as source code? Is it possible to recompile it and upload a modified version that works around this check? (since I can set /data to be readable by everyone anyway)
I fixed this issue for a HTC Desire S (2.3.3) by changing access & ownership for directory '/data/data':
Before the fix:
ls -l /data
(...)
drwxrwxrwx root root 2012-03-03 19:07 data
In root mode:
chmod 771 /data/data
chown system.system /data/data
ls -l /data
(...)
drwxrwx--x system system 2012-03-03 19:07 data
Also the /data director may need changing.
chmod 771 /data
chown system.system /data
Have same problem with my HTC Legend. My workaround:
get root access
get PID of app you want to debug: ps | grep your_app_package
run gdb server: /data/data/your_app_package/lib/gdbserver :5039 --attach PID
in new terminal
adb forward tcp:5039 tcp:5039
adb pull system/bin/app_process project_path/obj/local/armeabi/app_process
adb pull system/bin/libc.so /project_path/obj/local/armeabi/libc.so
Now you can connect to gdbserverb (http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-debugging/#more-23 skip steps with ndk-gdb).
PS: dont forget compile your code with following flags
LOCAL_CFLAGS := -g #debug
LOCAL_LDFLAGS := -Wl,-Map,xxx.map #create map fil
Stumbled upon this thread: http://code.google.com/p/android/issues/detail?id=16391
Solved run-as issue for me, ndk-gdb now works properly.
I used to get this problem, until I changed the package name to be 4 nested instead of 3. Don't know why that is an issue (already emailed the developers about it) but if your package name is a.b.c only the java debugger works. For native debugging it needs to be in the form of a.b.c.d.
The path /should/ be correct (both "data" directories are 771 and
system:system, the app's data directory is 755 and owned by an "app_"
account).
