Where does android studio save sqlite db on Linux dev machine? - android

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

How to install over existing Android app on device using adb?

During development, I use something like
$ adb -s 192.168.1.77:5555 uninstall com.myApp.app
$ adb -s 192.168.1.77:5555 install /path/to/android-debug.apk
to uninstall the existing app, then push and install the updated app to my device. However, this seems to erase my existing data associated with the app so that each time I run the updated app I need to input the new data again. However, simply running the install command gives:
[ 10%] /data/local/tmp/android-debug.apk
[100%] /data/local/tmp/android-debug.apk
pkg: /data/local/tmp/android-debug.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
With iOS you can simply install your updated app over the existing app on the device.
What is the equivalent for Android preferably using adb?
Edit: This question is really similar to this one, but I think this should be kept because the way my question is phrased will help many people trying to find an answer that are coming from a different angle– the angle being of reinstalling/overwriting versus updating.
from adb --help
adb install [-lrtsdg] <file>
- push this package file to the device and install it
(-l: forward lock application)
(-r: replace existing application)
(-t: allow test packages)
(-s: install application on sdcard)
(-d: allow version code downgrade (debuggable packages only))
(-g: grant all runtime permissions)
Therefore you can just add -r option
$ adb -s 192.168.1.77:5555 install -r /path/to/android-debug.apk

Get SQLite database from Android app

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>

How to access sqlite DB on the Xoom?

I have a Nexus One (rooted) and a Xoom (stock, not rooted).
I have developed on my Nexus for quite some time, without any problems. I'm facing one with the Xoom, however, as it is not rooted.
Indeed, I use sqlite databases in my apps, and I would like to debug them using sqlite3 as I do on my Nexus.
It doesn't work!
$ pwd
/
$ id
uid=2000(shell) gid=2000(shell) groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),3001(net_b_admin),3002(net_bt),3003(inet)
$ sqlite3 /data/data/org.bicou.newsreader/databases/subscriptions.db
sqlite3: permission denied
I can't! How come? How am I supposed to develop? I'm sure I'm missing something but I don't know what.
Also, adb pull doesn't want to pull, and cat / cp / mv don't work either. I don't want to write specific code in my app just to browse the DB...
If it is your app you're debugging, there is no need to root the device.
Edit this list of commands to your package name and db file name, and paste it into a shell:
adb wait-for-device shell <<EOF
run-as [YOUR_PNAME]
chmod 666 databases/[YOUR_DB_FILE_NAME].db
exit
exit
EOF
adb pull /data/data/[YOUR_PNAME]/databases/[YOUR_DB_FILE_NAME].db
sqlitebrowser [YOUR_DB_FILE_NAME].db &
The sqlitebrowser can be replaced with whatever sqlite3 application you have on your pc.
I rooted my device as well. But new system image doesn't have sqlite3 in path.
I ended up rooting the device.

How to install or get access to sqlite3 from adb shell

I need a way to install or somehow get access to sqlite3 in the adb shell. I have rooted my device.
I've tried to find an answer but the closed I could come is:
Why do I get a "sqlite3: not found" error on a rooted Nexus One when I try to open a database using the adb shell?
But I don't think it's good idea to push my windows sqlite3.exe on a linux system?
So is it possible to install the sqlite3 terminal browser somehow?
[SOLUTION]
From the different comments and some asking around at #android-dev (irc), I found a solution. First I copied the database file to my desktop. But fist I had to install BusyBox, because cp isn't included?!? After that ran I into the problem that I couldn't pull or push from anywhere but /sdcard/ . I could then use /sdcard/ as a "middle station" and pull/push my db.
Then I got exhausted! I really had to have my sqlite terminal explore. Then I got the idea to start the emulator pull the sqlite binary from /system/xbin/sqlite3. Then remount /system with rw:
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
and push sqlite to the /sdcard/, and from there copy it to /system/xbin/
Now it works :D
Download this app from google play will help you install sqlite3 on android https://play.google.com/store/apps/details?id=ptSoft.util.sqlite3forroot
You don't need root to pull the database from your device. Simply run the following commands:
adb shell run-as <package-name> "cp databases/<db_name>.db /sdcard/ && exit"
adb pull /sdcard/<db_name>.db ~/Downloads/
From there, you can use sqlite3 for whatever operating system you're using (http://www.sqlite.org/download.html), or a sqlite browser such as "DB Browser for SQLite" (http://sqlitebrowser.org/)
I use Rajath's technique... Adb "Pull" the db from the emulator/device, work on it, then adb "push" it back onto/into the emulator device.
also:
I use the free SQLite Editor from the Android Market. I have not rooted my LG Ally and therefor can only edit database tables on my sdcard with SQLite Editor.
Rajath suggests using the adb to push and pull the databases to and from the emulator/device. The work on the database with the windows (or whatever) sqlite3 program you have. He does not suggest pusing the windows sqlite3 onto the Android device, IMHO.
I note that java/android "query()" sends actual SQL commands programmacitacly to ones program with user input. I conclude that sqlite3 is in Android somewhere.
When using the emulator Dev Tools is available, and way down at the bottom of the list is the Terminal Emulator. This allows exploration of file structure of Android in the emulator. However using "adb shell" from the PC has root permissions.
good luck. cactus mitch
You can do this with adb shell without issue.
In terminal or CMD (assuming you have the ADB path set and your phone has ROOT) type:
$ adb shell
$ cd data/data/com.nameofyourpackage/databases/
$ ls to find the name of your database
$ sqlite3 nameofyourdb.db
Then you can use .tables .schema to see the data you need to create the appropriate query.

Android ADB commands missing

I've got Android 2.2 on my phone and I'm doing some DB development. I've been trying to query my DB using sqlite3, but it looks like sqlite3 is missing from my phone. So then I tried a few other commands (su, find etc) and they ALL seem to be missing.
Can anyone tell me where they have gone please? I read somewhere that sqlite3 at least might have been accidentally left out of 2.2, but surely they can't all have been missed off can they?
Thanks
With the new release, adb has moved to platform-tools while all other tools are still under tools folder.
You can either copy them or add them to the Windows Path (if you are using windows).
Try:
$ adb -s <serialno> shell type sqlite3
sqlite3 is /system/xbin/sqlite3
to determine if sqlite3 is available or not on you device.
The command you entered in one of your comments is malformed, it should be (after you determined that sqlite3 is available):
$ adb -s <serialno> shell sqlite3 /data/data/com.example.google.rss.rssexample/databases/rssitems.db
SQLite version 3.6.22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite>
Those aren't adb commands those are binaries usually installed on rooted devices. If your device isn't rooted you aren't going to be able to install them either.
However, what you can do to get into your apps database. Use the activity manager command set-debug-app [options] <PACKAGE> This will let you access your apps database without being rooted, then you can pull it to your desktop and use sqlite3 from there.
Something like this:
adb shell
am set-debug-app com.example.appname
exit ##exit adb shell
adb pull data/data/com.example.appname/databases/exampledb.db exampledb.db
sqlite3 exampledb.db
Your app needs to be set to debugging true in the manifest for this to work.
