I have a flutter project that i created and manage with vscode.
I now need to access some files on my android emulator.
Everything i read online references the File Explorer tool in android studios.
However, i am not using android studios and i dont have a android studio project.
The only way i see at the moment is to abandon using vscode and recreate my project using android studios then using the file explorer from there...
However, this seems silly and excessive... i am sure there is someway i can access the file on my emulator without having to trow vscode in the trash.
Any ideas?
You can't access emulator's file system from VS Code as of now. If you don't want to use Android Studio then an alternative way is to use ADB Shell.
Here are the commands that you can use to interact with the File System of your emulator.
adb pull - To copy a file or directory and its sub-directories from the Android device
adb push - copy local files/directories to Android device
adb shell ls- List Files and Directories
adb shell cd - change directory
adb shell rm - rm is a command-line utility for removing files, directories and symbolic links
adb shell mkdir - make directories
adb shell touch- the touch command is a standard command used in UNIX/Linux operating system which is used to create, change and modify timestamps of a file
adb shell pwd - printing the current working directory
adb shell cp - copy files and directories
adb shell mv - moves files or directories from one place to another
For a detailed example please visit ADB Shell.

I'm using ADB in order to copy files from my desktop to a folder on my emulator.
adb push pic.jpg '/storage/emulated/0/DCIM/camera/
This works fine, but I have many files I would like to copy, and I don't want to repeat this command for every file. How can I "push" the contents of a whole directory?
Edit: screenshot of my Android studio:
For uploading the whole directory, the easiest way is to use Device File Manager in Android Studio.
Open it from the bottom right toolbar and navigate to the directory in the device where you want to upload the data.
Right click and click on upload to upload files or directory.
Note: Works only in Android Studio 3.0 and above
To push everything in the current directory, you can try:
adb push * /storage/emulated/0/DCIM/camera/*
You could use tar to put all your files into a single archive:
tar -cvf all.tar .
Then push that archive to the device:
adb push all.tar /sdcard
Finally untar your tar file in the device:
adb shell tar -xvf /sdcard/all.tar -C /sdcard
I couldn't find a solution so I made one:
from ppadb.client import Client as AdbClient
import os
import glob
adb = AdbClient(host='127.0.0.1', port=5037)
devices = adb.devices() #List of all connected devices
def send_over_adb(device,hostpath,devpath="/storage/emulated/0/"): # Recursively send folder and files over adb
if os.path.isfile(hostpath):
devpath = os.path.join(devpath,hostpath).replace('\\','/') # optimization for windows
device.push(hostpath, devpath)
elif os.path.isdir(hostpath):
for i in glob.glob(hostpath+'\*'):
print(i)
send_over_adb(device,i,devpath)
device.shell('am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard')
device.shell('am force-stop com.android.gallery3d') #force create thumbnails
hostpath='\path\to\folder\or\file\'
send_over_adb(devices[0],hostpath,devpath)
This function recursively sends over the folders and files while maintaining folder structure and ignores empty directories.
Limitation: file name shouldn't contain forward or back slashes(idk if any os allows that though)
Dependency: pure-python-adb
Tested on: Python3.7.9 on Win 8.1
I'd like to insert data directly into the sqlite database of my app but I cannot find it anywhere on android studio path, even on my root path:
$sudo find / -type f -name 'myapp.db'
I know several similar questions have been asked before but the answers for Windows did not help me on Ubuntu Linux. So appreciate your help.
Android Studio does not store the database locally in your computer. The databases only exist in the devices & every time you deploy to a new device, your database will be created new in that new device. That is why you can't find it in your computer. Here is where the database is located in the device:
/data/data/full_qualified_java_package_name/databases/database_name.db
Now if you would like to insert data directly, you can use the terminal in Android Studio & use ADB to pull the database off the emulator, modify it, and push it back in. Heck I am sure that if you know enough Linux you could probably insert what you need into it without pulling it from the device. Here are some sample commands for the Android Studio terminal for that:
~/Android/Sdk/platform-tools/adb devices
Get the device number, then:
~/Android/Sdk/platform-tools/adb -s emulator-#### pull /data/data/full_qualified_java_package_name/databases/database_name.db <local-filepath>
And to send it back in, it is just:
~/Android/Sdk/platform-tools/adb -s emulator-#### push <local-filepath> /data/data/full_qualified_java_package_name/databases/database_name.db
Example:
~/Android/Sdk/platform-tools/adb -s emulator-5554 pull /data/data/com.danielkaparunakis.stackoverflowquestions/databases/Questiondatabase.db /Users/DanielKaparunakis/Desktop
Additional tip: If you leave the blank when you pull like this:
~/Android/Sdk/platform-tools/adb -s emulator-5554 pull /data/data/com.danielkaparunakis.stackoverflowquestions/databases/Questiondatabase.db
It will automatically pull it to your project's root folder.
It will save it in the internal storage of every device, if you don't have a rooted device it will not allow you to pull it, but, if you are using an emulator you will be able to pull it.
https://developer.android.com/training/basics/data-storage/databases.html
You app's db is only on the device. You can pull it from any connected device – non-rooted physical devices as well. This script pulls it from the first device.
This trick is run-as <package name> which runs a shell the app's directory with full access to the app's data.
Replace $package with your app's package name and replace $db with the name of you app's db.
$ LC_ALL=C adb exec-out run-as $package cat databases/$db >db.sqlite
LC_ALL=C is to avoid some strange locale behavior on some systems.
adb is by default installed by Android Studio to ~/Android/Sdk/platform-tools/adb.
Update
The program 'adb' is currently not installed. To run 'adb' please ask your administrator to install the package 'android-tools-adb'
This is Ubuntu telling you that you can install it from the Ubuntu package manager.
Normally you would already have it as a part of Android Studio.
Update 2
I don't have a script yet for pushing it back since push and run-as don't work together. You would have to do something like this (untested).
$ adb push db.sqlite /sdcard/temp.sqlite
$ cat <<EOF | adb shell
run-as $package
cat /sdcard/temp.sqlite >databases/$db
exit
exit
EOF
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.
I need get SQLite database from Android app from Genesis device where user has populated by hand.
How I can create another app or any other way to get this db and save in place where I can get?
obs.: the device has root
Thanks
Steps from .../platform-tools of Android on cmd:
1) type adb shell
2) run-as com.your.package
3) type ls
cache
databases
lib
You can find Your Database Here...Also You didn't even have to root the Device
Hope this could helpful for you...
Provided you have the device attached to a box with adb on the PATH you can use this command:
adb -d shell 'run-as your.package.name.here cat /data/data/your.package.name.here/databases/your_db_name_here.sqlite > /sdcard/recovered_db.sqlite'
Or you can use Ecliplse DDMS file explorer.
VERY EASY WAY TO DO IT
In the latest releases of Android Studio (I am using AS v3.1.2) the Google team has made it really straight forward. You just have to open the Device File Explorer window which should be at the bottom of the right vertical toolbar, if you cannot find it you can also open it this way:
View -> Tool Windows -> Device File Explorer
Once you have Device File Explorer window open, use your mouse to navigate to the following path:
data -> data -> your.package.name -> databases
Inside the databases folder you should see the database you want to explore, do a right click and Save As... select your desired computer destination folder and voila!!
You can either include the Stetho library on your app,
http://facebook.github.io/stetho/
which will allow you to access your DB using Chrome's Web Debug tools
or use the following shell script:
#!/bin/bash
echo "Requesting data from Android"
adb backup -f data.ab -noapk YOUR.APK.NAME
echo "Decoding...."
dd if=data.ab skip=24 iflag=skip_bytes | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" | tar -xvf -
rm data.ab
echo "Done"
```
None of the methods above require your device to be rooted and the latter works even on apps that you did not write yourself, as long as the ApplicationManifest.xml does not contain "backup=false"
After trying dozens of commands that didn't work for me on Marshmallow, I've found this one that works (for debuggable apps at least):
adb shell "run-as your.package.name cp /data/data/your.package.name/databases/you-db-name /sdcard/file_to_write"
Then you simply can view the DB with aSQLiteManager for instance.
You can use this script.
humpty.sh
You should know the application package name and sqlite database name.
You can check the available databases.
$ adb shell
$ run-as <package-name>
$ ls databases/
To dump database or other file.
./humpty.sh -d <package-name> databases/<db-name>
Trying to copy file from device to desktop, here is a command:
adb pull sdcard/log.txt Users/admin/Desktop
But this command creates a folder Users/admin/Desktop inside platform-tools folder where adb is located. How to pull file to my desktop ?
Use a fully-qualified path to the desktop (e.g., /home/mmurphy/Desktop).
Example: adb pull sdcard/log.txt /home/mmurphy/Desktop
Judging by the desktop folder location you are using Windows. The command in Windows would be:
adb pull /sdcard/log.txt %USERPROFILE%\Desktop\
Be root, Define file on device and define new filename.
adb root
adb pull /data/data/.../databases/launcher.db launcher.db
On Windows, start up Command Prompt (cmd.exe) or PowerShell (powershell.exe). To do this quickly, open a Run Command window by pressing Windows Key + R. In the Run Command window, type "cmd.exe" to launch Command Prompt; However, to start PowerShell instead, then type "powershell". If you are connecting your Android device to your computer using a USB cable, then you will need to check whether your device is communicating with adb by entering the command below:
# adb devices -l
Next, pull (copy) the file from your Android device over to Windows. This can be accomplished by entering the following command:
# adb pull /sdcard/log.txt %HOME%\Desktop\log.txt
Optionally, you may enter this command instead:
# adb pull /sdcard/log.txt C:\Users\admin\Desktop\log.txt
List item
Use following command to pull data from ADB
adb pull data/user/0/project package name/files/.local/share/dbname C:\Users\vijayalaxmi.k
data/user/0/project package name/files/.local/share/dbname this path you will get when you debug application. i.e database path
project package name example => com.example
instead of C:\Users\vijayalaxmi.k user your own path where you want to save your file. for example, c:\documents
do adb pull \sdcard\log.txt C:Users\admin\Desktop
