My working directory is /data/local/tmp.
I create and push a shell script file here named get_meminfo.sh.
The core function of it is record the RSS usage and save as a log file, like this: rss_res >> rss.log
But now I find a problem: I can run the script file when I enter the android shell, like ./get_meminfo.sh, and I can see the log file created in the path.
However when I try to run it from adb, like: adb shell /data/local/tmp/get_meminfo.sh， it will get an error: can't create file, read-only file system!
It seems that you do not quite understand the concept of the current working dirtectory.
The rss_res >> rss.log command creates rss.log in the current working dirtectory. Which in case of the following command sequence is /data/local/tmp:
adb shell
cd /data/local/tmp
./get_meminfo.sh
So rss.log gets created in /data/local/tmp which is world writable.
But in case of adb shell /data/local/tmp/get_meminfo.sh the cwd is the / root folder. Which is not writable and the command fails.
The easiest way to mitigate that is to use the absolute path for your log file inside of your script like this rss_res >> /data/local/tmp/rss.log
When I run below command directly on prompt, it works fine by pulling all files from emulator sdcard:
adb -s emulator-5556 pull /sdcard/.
However when I create bash file (extract.sh) with above command and run it I get following error:
remote object 'C:/Program Files (x86)/Git/sdcard/' does not exist
As can be seen it somehow adds C:/Program Files (x86)/Git before it. These are the contents of bash file:
#!/bin/bash
adb -s emulator-5556 pull /sdcard/.
Does anyone have an idea of why it works when direcly typing on prompt and not via bash file ? Thanks
Is there any reason you're not specifying the destination directory? For example, the batch command I use when pulling pictures from my phone over USB is adb pull "/sdcard/DCIM/Camera" "E:\Phone Pics\HTC DNA" which specifies both the source directory on the phone and the destination directory on my computer. As a side note, like enedil I recommend using this in a batch file when working in Windows.
How to push a file from computer to an Android device having no SD Card in it. I tried:
C:\anand>adb push anand.jpg /data/local
3399 KB/s (111387 bytes in 0.032s)
C:\anand>adb push anand.jpg /data/opt
3199 KB/s (111387 bytes in 0.034s)
C:\anand>adb push anand.jpg /data/tmp
3884 KB/s (111387 bytes in 0.028s)
Above commands to move a file anand.jpg to a device but I didn't get this jpg file in the device.
I didn't get any success result on cmd prompt, I only got:
3399 KB/s (111387 bytes in 0.032s).
From Ubuntu/Mac Terminal, the below command should work.
./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/'
For adb v33 and above if you are getting a permission denied error, try what I tried. The following command and it works fine.
The only caveat is you might need to use tmp directory on such an emulator.
adb shell //Entering into shell
su //Super user mode
chmod 777 /data/local/tmp/ //Grantint RWX access
exit
chmod 777 /data/local/tmp/ //Grantint RWX access
exit
And then try
./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/tmp/'
I did it using the push command, which has syntax:
adb push filename.extension /sdcard/0/
Example of copying directory, and sub-directory content:
adb push C:\my-location\data\. /storage/emulated/0/Android/data
Note that push did just hang in latest platform-tools (33.0.1, at time of writing) for a certain amount of files, beside the adb.exe suddenly taking 5MB+ instead of 1.5MB, hence I just did replace the adb.exe with one I had from 28.0.0 version of platform-tools (I did not downgrade the entire platform-tools, because adb.exe is kind of stand-alone).
I don't say there is any conspiracy around data folder,
But my Samsung device puts limits on my USB file transfer, beside Android v11+ not allowing access to data folder anymore, hence I needed above command to work with 100% speed (without hanging one hour for little more files).
Follow these steps :
go to Android Sdk then 'platform-tools' path on your Terminal or Console
(on mac, default path is : /Users/USERNAME/Library/Android/sdk/platform-tools)
To check the SDCards(External and Internal) installed on your device fire these commands :
1) ./adb shell (hit return/enter)
2) cd -(hit return/enter)
now you will see the list of Directories and files from your android device
there you may find /sdcard as well as /storage
3) cd /storage (hit return/enter)
4) ls (hit return/enter)
you may see sdcard0 (generally sdcard0 is internal storage) and sdcard1 (if External SDCard is present)
5) exit (hit return/enter)
to come out of adb shell
6) ./adb push '/Users/SML/Documents/filename.zip'
/storage/sdcard0/path_to_store/ (hit return/enter)
to copy file
Sometimes you need the extension,
adb push file.zip /sdcard/file.zip
run below command firstly
adb root
adb remount
Then execute what you input previously
C:\anand>adb push anand.jpg /data/local
C:\anand>adb push anand.jpg /data/opt
C:\anand>adb push anand.jpg /data/tmp
After Trying all the answers this worked for me
Where I am Pushing a file on Desktop to Android Device (Redmi K20 pro) connected Over the air using adb.
This command pushes the file to the downloads folder on my phone
adb push ~/Desktop/notifications.drawio ./storage/emulated/0/Download
after running this if you get a permission denied error
try running these commands in order (which basically changes the directory permission)
adb shell
chmod 777 /data/local/tmp
exit
and then run try the adb push command
I have documented this here feel free to share your views and help improve it.
Try this to push in Internal storage.
adb push my-file.apk ./storage/emulated/0/
Works in One plus device, without SD card.
My solution (example with a random mp4 video file):
Set a file to device:
adb push /home/myuser/myVideoFile.mp4 /storage/emulated/legacy/
Get a file from device:
adb pull /storage/emulated/legacy/myVideoFile.mp4
For retrieve the path in the code:
String myFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myVideoFile.mp4";
This is all. This solution doesn't give permission problems and it works fine.
Last point: I wanted to change the video metadata information. If you want to write into your device you should change the permission in the AndroidManifest.xml. Add this line:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I've got a Nexus 4, that is without external storage. However Android thinks to have one because it mount a separated partition called "storage", mounted in "/storage/emulated/legacy", so try pushing there: adb push anand.jpg /storage/emulated/legacy
As there are different paths for different versions. Here is a generic solution:
Find the path...
Enter adb shell in command line.
Then ls and Enter.
Now you'll see the files and directories of Android device. Now with combination of ls and cd dirName find the path to the Internal or External storage.
In the root directory, the directories names will be like mnt, sdcard, emulator0, etc
Example: adb push file.txt mnt/sdcard/myDir/Projects/
This might be the best answer you'll may read.
Setup Android Studio
Then just go to view & Open Device Explorer.
Right-click on the folder & just upload a file.
In Mac: To push files via adb
adb push /Users/Downloads/amazon.sdktester.json '/mnt/sdcard/amazon.sdktester.json'
You are trying to write to system folders. With ADB you have root (admin) access so you see the system folders of which sdcard is one of them so to send a picture you could use
D:\Program Files\Android\sdk\platform-tools\adb push am files\android sdk\adb.exe push C:\Downloads\anand.jpg /sdcard/pictures/
NB: C:\Downloads\anand.jpg replace with path and name to picture..
Certain versions of android do not fire proper tasks for updating the state of file system.
You could trigger an explicit intent for updating the status of the file system.
(I just tested after being in the same OP's situation)
adb shell am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///
(You could pass a specific filepath instead of file:/// like file:///sdcard )
In my case, I had an already removed SDCard still registered in Android.
So I longpressed the entry for my old SDCard under:
Settings | Storage & USB
and selected "Forget".
Afterwards a normal
adb push myfile.zip /sdcard/
worked fine.
To push all the files at your directory to the Android device use:
PS D:\myFiles> adb push . '/data/local/tmp/'
i want to redirect the Android developer tools logcat output to a file into the virtual device from a shell command, before than running the android app test.
The command i usually use to redirect the output to a file is:
adb shell logcat -v time - f log.txt packageName:F *:E > /folder/log.txt
but it puts the log file into a computer directory (/folder/ in this case).
I want to change it with a directory in the virtual device but like above, it says the folder does not exist.
There is way to do it via shell command?
You can simply do
adb shell "logcat -v time -f /mnt/sdcard/log.txt packageName:F *:E"
to accomplish it all in one command from the host shell. You do not need the redirect when you use the -f flag, in fact the redirect would not capture anything if you have directed the output of logcat to a file rather than to stdout.
If that is not working, it is either because you are using a version of Android which mounts the external storage at some other path, or you do not have an emulated sdcard attached to your virtual device.
You can investigate either of these problems by examining the output of
adb shell mount
If you do not have an sdcard at all on your AVD, follow the emulator documentation instructions for creating and attaching one.
For testing purposes only there may be other paths than the sdcard at which you can write, particularly on an emulator where the adb shell runs as root, for example on some versions /data/local or similar.
You can try this one adb shell then #logcat>/sdcard/log.txt now i am sure about the results.you just need a command prompt window to be opened for adb shell,that's not so bad i guess.
i am not able to run shell scripts from my application.only "ls -l" and echo commands respond.rest dont seem to do anything.not even "touch" command works.i tried creating a file in sdcard using touch command in my script..only the echo command worked.my shell script is in sdcard too
The sdcard is mounted with noexec. You will have to copy the scripts to the app's local data drive to execute.
You should be able to see the mounted permissions of all file-systems by logging into the phone (adb shell or whatever else) and typing mount
The rest of the commands like "cd" etc doesnot work in Android as it encounters lot of permission issues.
So the best solution is to trigger "script manager" or "terminal emulator" apps already available through your app.
