access Settings > Safety & emergency via adb commands?
I tried below commands but none are working.
adb shell am start -n com.android.settings/com.android.settings.emergency.EmergencyDashboardFragment
Starting: Intent { cmp=com.android.settings/.emergency.EmergencyDashboardFragment }
Error type 3
Error: Activity class {com.android.settings/com.android.settings.emergency.EmergencyDashboardFragment} does not exist.
emu64xa:/ # am start -n com.android.settings/com.android.settings.emergency.EmergencyDashboardFragment
adb shell am start -n com.android.settings/com.android.settings.SubSettings -e :android:show_fragment com.android.settings.emergency.EmergencyDashboardFragment
This only opens the settings, but not Settings > Safety & emergency
I run a command in Linux remote machine using plink (from batch file in Windows).
For example:
plink.exe -ssh root#IP -pw pass -m testCommands.txt >> uninstall.log
In testCommands.txt I have a command that perform uninstall of application,
the problem is that command of "uninstall" require an answer (y or n),
How can I send answer in addition to what I already send?
Here is the question I have:
[?7hAre you sure you want to completely remove "APPLICATION" and all of its components?
Yes [y, Enter], No [n]"
There are several options...
Use a -y or auto-confirm option on the command that removes the software, e.g.
pkg rm -yes somePackacge
Use a pipe to send the yes, so that the command you run in PLINK looks like
printf "Yes\n" | pkg rm some_package
or
yes | pkg rm some_package
Make the command that you run on the Linux machine be based on expect which can spawn your remove command, wait for a question and then send it a confirmation. Some expect examples here.
I was doing what suggested here: Sending AT Commands Via ADB Android
So after I rooted my Samsung S5, I found my modem with this command: getprop rild.libargs and I got this result: -d /dev/smd0
Then I typed into my adb shell: echo -c "AT\r\n" > /dev/smd0
But nothing is returned.
I don't understand, any idea ?
I also tried other commands like: AT+CREG or AT+COPS=?, still nothing.
I am trying to connect to a serial port and send a series of commands from a file.
Firstly I have mananged to connect via the following:
PuTTY.exe -serial COM3 -sercfg 57600,8,n,1,N
E.g. I have a file called commands.txt with a series of serial commands I wished to be sent.
I tried the following however it failed to work:
PuTTY.exe -serial COM3 -sercfg 57600,8,n,1,N -m commands.txt
Any help is greatly appreciated.
Try like this :
for /f "delims=" %%a in ('type commands.txt') do PuTTY.exe -serial COM3 -sercfg 57600,8,n,1,N -m %%a
Another solution which I have used to regularly send commands to a device uses a combination of PuTTY and Autohotkey.
For the initial setup, configure a PuTTY session and save it. In my case I named is Oasis.
The following Autohotkey function can send a command to the already open PuTTY session. If PuTTY is not open it will start the saved session. oasis_putty_name() is the name of the PuTTY window once it's open, it will depend on the COM port selected. location_putty() is the location of the PuTTY executable. Both of these can be hard coded but I wanted to keep the variables separate from the functions.
; Oasis Check --------------------------------------------------
oasis_check(){
putty_name := oasis_putty_name()
; Start PuTTY if it's not already running
IfWinNotExist, %putty_name%
{
putty := location_putty()
Run %putty% -load Oasis
Sleep,1000
}
; Format Time Stamp
FormatTime, TimeString,,yyyy-MM-dd HH-mm-ss
; Record Oasis Values
ControlSend, , %TimeString%{ENTER}, %putty_name%
Sleep, 2000
ControlSend, , all?{ENTER}, %putty_name%
}
The frequency of execution can be controlled with another Autohotkey script or, as in my case, with the Windows Task Manager.
I just rooted my Nexus 5 using this method: http://www.phonearena.com/news/How-to-root-Google-Nexus-5_id49014
I also enabled USB debugging in the developer options.
Then I tried to pull a database file from my device using this command:
adb pull /data/data/path.to.package/databases/data /sdcard/test
I get permission denied error.
I don't have the debugged flag set in that app I tried to access. Is that the reason I can't access that file? If yes, are there any workarounds to access an apps files?
You can use run-as shell command to access private application data.
If you only want to copy database you can use this snippet, provided in
https://stackoverflow.com/a/31504263/998157
adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db
I had the same problem. My work around is to use adb shell and su. Next, copy the file to /sdcard/Download
Then, I can use adb pull to get the file.
Did you try adb remount after giving adb root?
This generic solution should work on all rooted devices:
adb shell "su -c cat /data/data/com.android.providers.contacts/databases/contacts2.db" > contacts2.d
The command connects as shell, then executes cat as root and collects the output into a local file.
In opposite to #guest-418 s solution, one does not have to dig for the user in question.
Plus If you get greedy and want all the db's at once (eg. for backup)
for i in `adb shell "su -c find /data -name '*.db'"`; do
mkdir -p ".`dirname $i`"
adb shell "su -c cat $i" > ".$i"
done
This adds a mysteryous question mark to the end of the filename, but it is still readable.
If you get could not copy and permissions are right disable selinux.
Check if selinux is enabled.
$ adb shell
$su
# getenforce
Enforcing
Selinux is enabled and blocking/enforcing.
Disable selinux
# setenforce 0
do your stuff and set selinux to enforcing.
# setenforce 1
I had just the same problem, here's how to deal with it:
adb shell to the device
su
ls -l and check current access rights on the file you need. You'll need that later.
go to the file needed and: chmod 777 file.ext. Note: now you have a temporary security issue. You've just allowed all the rights to everyone! Consider adding just R for users.
open another console and: adb pull /path/to/file.ext c:\pc\path\to\file.exe
Important: after you're done, revert the access rights back to the previous value (point 3)
Someone mentioned something similar earlier.
Thanks for the comments below.
This answer ended up working for me: https://stackoverflow.com/a/15559278/53001
Backup to a file, pull the backup, and then convert it to a tarball and extract it.
adb backup -f myAndroidBackup.ab com.corp.appName
dd if=myAndroidBackup.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" | tar -xvf -
$ adb shell
$su
# getenforce
Enforcing
now try
adb shell
su
chmod 777 /path/to/yout_file
exit from shell
open new CMD and try adb pull /path/to/yout_file
It will work fine now.
you'll have security problems because of this any application will be able to access your database.
#guest-418 tips works well:
adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db
However, if you want to use a GUI, use Android Studio's Device File Explorer.
Launch Android Studio
Click on Device File Explorer at bottom right-side
Navigate to your app's file:
/data/data/path.to.package/databases/data
Right-mouse click select Save As and save to a local folder
I have been having Android Monitor hang on me lately on macOS. Device File Explorer works well for this purpose.
Create a folder in sdcard :
adb shell "su 0 mkdir /sdcard/com.test"
Move your files to the new folder :
adb shell "su 0 mv -F /data/data/com.test/files/ /sdcard/com.test/"
You can now use adb pull :
adb pull /sdcard/com.test
When executing adb commands, by default, a limited privileges user is used, the same kind of limited privilege user that is assigned to an app, and you have requested for all privelages to use all features of the device.
This kind of limited user helps protect your phone from malware, by restricting the access between apps, and the system. This is the reason you are unable to access app data and system data on an unrooted phone. The act of rooting means becoming user 0, the super user of the system, capable of any action, and is the highest privilege. Your apps however, are still secure in that they can not talk to eachother.
Now when accessing secure files, note that you do not want to change the permissions of the file when you access it, which may allow for vulnerabilities.
An option that you could use instead, is to make a copy of the file on the sdcard as root, modify that as a standard user, and then move it back into the filesystem as root, while preserving the file permissions of the original file.
Since I've updated to Android Oreo, I had to use this script to fix 'permission denied' issue.
This script on Mac OS X will copy your db file to Desktop. Just change it to match your ADB_PATH, DESTINATION_PATH and PACKAGE NAME.
#!/bin/sh
ADB_PATH="/Users/xyz/Library/Android/sdk/platform-tools"
PACKAGE_NAME="com.example.android"
DB_NAME="default.realm"
DESTINATION_PATH="/Users/xyz/Desktop/${DB_NAME}"
NOT_PRESENT="List of devices attached"
ADB_FOUND=`${ADB_PATH}/adb devices | tail -2 | head -1 | cut -f 1 | sed 's/ *$//g'`
if [[ ${ADB_FOUND} == ${NOT_PRESENT} ]]; then
echo "Make sure a device is connected"
else
${ADB_PATH}/adb exec-out run-as ${PACKAGE_NAME} cat files/${DB_NAME} > ${DESTINATION_PATH}
fi
This is a bit late, but installing adbd Insecure worked for me. It makes adb run in root mode on production ("secure") devices, which is what you likely have.
A paid version is also available on Google Play if you want to support the developer.
I had a similar problem to yours on windows as the following.
D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
adb: error: failed to copy '/data/local/tmp/com.packagename_dumped_1766.dex' to 'D:\ProgramFiles\Android\com.packagename_dumped_1766.dex': remote Permission denied
My solution:
At first I also made an attempt to use cat as ansi_lumen answered, but I got into trouble about CR and LR (\r\n) characters.
And then I just had to change those file permisions by chmod and pulled again to this problem was solved without introducing other problems. After that, may
we need to restore their original permissions as Goran Devs answered.
So just pay a little attention.
TL;DR
My story:
Firstly, I used the cat to download all files from android to my windows,
#echo off
cd /d %~dp0
:: %~dp0 = D:\ProgramFiles\Android\
SET ThisBatDir=%~dp0
:: adb shell ls /data/local/tmp/com.packagename_dumped_* > %~dp0\dump_file_list.txt
FOR /f "delims=" %%a in ('adb shell ls /data/local/tmp/com.packagename_dumped_*') do call :processline %%a %%~nxa
goto :eof
:: https://stackoverflow.com/questions/232651/why-the-system-cannot-find-the-batch-label-specified-is-thrown-even-if-label-e
:processline
SET RemoteFullPath=%1
set FileName=%2
:: echo "%RemoteFullPath%|%ThisBatDir%|%FileName%"
call adb shell su -c cat %RemoteFullPath% > %ThisBatDir%%FileName%
goto :eof
:eof
However, those downloaded dex files were broken because of CR and LR (\r\n) characters on windows.
We can use hexdump to inspect its content in Hex+ASCII form (or Notepad++ with "View > Show Symbol > Show All Characters" checked). Note, the 5th and 6th byte (0d 0a)).

Even if restarting adbd as root, it was still the shell user after .

So I first viewed its file permision,
D:\ProgramFiles\Android> adb shell ls -l /data/local/tmp
-rwsr-sr-x shell shell 589588 2017-09-14 15:08 android_server

-rwxr-xr-x shell shell 12808 2020-03-26 22:16 mprop
then, changed its permision,
D:\ProgramFiles\Android> adb shell su -c chmod 777 /data/local/tmp/com.packagename_dumped_*
D:\ProgramFiles\Android> adb shell ls -l /data/local/tmp
-rwxrwxrwx root root 57344 2020-03-28 17:45 com.packagename_dumped_1766.dex
As a result, I made it.
D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
/data/local/tmp/com.packagename_dumped_1766.de... 1 file pulled, 0 skipped. 3.6 MB/s (57344 bytes in 0.015s)
Now, jadx-gui-dev.exe or sh d2j-dex2jar.sh -f ~/path/to/apk_to_decompile.apk could properly enjoy them.
The pull command is:
adb pull source dest
When you write:
adb pull /data/data/path.to.package/databases/data /sdcard/test
It means that you'll pull from /data/data/path.to.package/databases/data and you'll copy it to /sdcard/test, but the destination MUST be a local directory. You may write C:\Users\YourName\temp instead.
For example:
adb pull /data/data/path.to.package/databases/data c:\Users\YourName\temp
