Is there a way for an Android user to browse the SQLite databases on his/her phone and view the data in the databases?
I use the SoftTrace beta program a lot. It's great but has no way that I can find to download the data it tracks to a PC.
The database for a specific app lives in /data/data/[packagename]/databases
The packagename is the package you define in your manifest, for instance /data/data/org.vimtips.supacount/databases/counts.db.
You can view it with adb shell and type sqlite3 /data/data/org.vimtips.supacount/databases/counts.db
Or you can pull it from the device to look at it with a third party utility, with a command like adb pull /data/data/org.vimtips.supacount/databases/counts.db ..
This assumes you have permission to view the database, which you might not have if you didn't write the app yourself... but in that case, is it actually a programming question?
If you are using Eclipse, you can use a plugin called 'Questoid SQLite Browser' to browse the SQL Lite Database on your Android emulator:
Install the plugin
Restart eclipse
Start your emulator
Switch to DDMS
Open database with plugin (as #synic mentioned previously, the DB is located here e.g. /data/data/my_project/databases)
Here is a more detailed tutorial: http://www.tylerfrankenstein.com/browse-android-emulator-sqlite-database-eclipse
Here is the free method that worked for me on a phone that is not rooted. Credit goes to this SO answer.
Use adb backup -f backup.ab -noapk app.package.name
On Windows download the Android Backup Extractor jar found on SourceForge here, then run java -jar abe.jar unpack backup.ab extractedbackup.tar. On Linux you can follow the dd instructions from the answer I gave credit to in the beginning.
Download SQLite Database Browser from SourceForge here, then open the db file contained within extractedbackup.tar.
Personally, to make this process easier, I first added adb to my environment PATH. Then I made a backup folder where I store all of the files mentioned above. This keeps me from having to cd (change directory) all over the place.
The Questoid plugin appears to cost $9 and requires registering. Another alternative on Windows is to download the open-source public-domain SQLLite Browser (link below) and then pull the database from the phone. In Eclipse you can do this from the File Browser, going to the /data/data/[packagename]/databases directory on the phone or emulator, and clicking "Pull a File From The Device" in the top right. Save the database locally, then open with the SQLite Browser.
http://sourceforge.net/projects/sqlitedbrowser/
Actually the most available (yet still hacky) way of getting "live" results from a database while developing on emulator that I found is this:
Create a script to pull the database from emulator, something like this
#!/bin/bash
ANDROID_HOME=/path/to/sdk
ADB=$ANDROID_HOME/platform-tools/adb
REMOTE_DB_PATH=/data/data/com.yourpackage.name/databases/your_db
LOCAL_DB_PATH=.
while true; do
echo copying DB...
`$ADB pull $REMOTE_DB_PATH $LOCAL_DB_PATH`
sleep 3
done
Run it.
Install SQLite Manager plugin for Firefox
Open your local copy of the database (which is constantly overridden by the running script from step 1)
Enter your SQL:
Select File->Reconnect
Click Run SQL
The key trick is that reconnecting does not reset SQL entered on step 4 (as it does, for example, in SQLite Browser), so you can repeat steps 5,6 to see "live" results from your android database.
Note that this only works for emulator, it won't work for a real device (even a rooted one).
You can view you database from your app using this library . https://github.com/sanathp/DatabaseManager_For_Android
With this library you can manage your app SQLite database from you app itself.
you can view the tables in your app database , update ,delete, insert rows to your tables
Its a single java activity file ,just add the java file to your source folder.When the development is done remove the java file from your src folder thats it .
It helped me a lot .Hope it helps you too .

If you were lucky enough to get IntelliJ Ultimate then you can plug the device in, open 'Database' tab on the right, click +, select SQLite. The rest is trivial.
One thing to keep in mind with it is that you have to keep clicking "Synchronize" button on the database (or on selected table) to see the changes made externally, which is very annoying.
See this answer. You can use Stetho library from Facebook and then just browser you database from Chrome :)

Do you know if there is a way to connected SQLite Studio (or similar) to the database via adb (emulator for Android), so I can see graphically my data via the laptop?
Thanks in advance
Actually you can use DbAndroid plugin (it's free, GPL'ed) that is shipped with SQLiteStudio (3.0.7). It will let you to connect to your android database without pulling or pushing the database file from/to an emulator or a device. It makes direct connection to the database in your application. Any changes to database made in SQLiteStudio will immediately be reflected in your running application.
Long story short - you add a jar file to your project as dependency, add few lines to inid/deinit the connector, then you add your database in SQLiteStudio and use it just as any other database.
There's a full manual on how to do it on SQLiteStudio's wiki page about this plugin: http://wiki.sqlitestudio.pl/index.php/DbAndroid
There's also a video demonstration on how to do it (also at that site). It's a bit too much to paste all of it here.
If you have any further problems with it, I'm happy to help (author here). You can also ask on SQLiteStudio's forum - I watch it often.
You can use Sqlite Studio to see your data: http://sqlitestudio.pl/
For internal storage you can get the database via adb:
adb pull /data/data/app_name/databases/db_name yourpath
If your database is in external just open it with Sqlite Studio.
I am using android studio to develop my first android app.
I am plugging in my phone, and testing my app on there to test changes as I go.
I am using a sqlite database. How do I view this database, the tables, and the contents (rows) of those tables?
Upon Google searching I found that this can be done when you root your phone. But surely you dont have to root your phone to view your databases when your developing an app?
Update:
People are using terminology assuming knowledge. If you want me to copy a database, explain how, if you want me to use adb, explain what it is. Otherwise it means not much to me. Thanks
Pull the sqlite database named as XYZ.db from your simulator or device using adb shell command or GUI interface provided by the AndroidStudio. Then Open it using The Sqlite Browser. It's a killer app for sqlite browsing.
As android is shipped with the sqlite3, you could use command line to view the data base saved inside the device / emulator. Command reference is Listed Sqlite3 android command
If you feel lazy enough to discover how to pull files from emulator / device using adb pull, following answer may help you.
how to pull
At least in my case I needed to root my device. After that I installed SQLiteEditor. With this app you can modify and view your database. Or if you don't want to install a new app you can use a root explorer and enter directly into your installed app in the DB. Is inside /data/data/{yourapp}.
Copy your database to your system
Using copy or paste Or
Using adb pull command
Then Googled for sqlitestudio-2.1.4, download and run , browse your database ,,then you can see your database rows, column, value etc.
ALL,
I wrote a simple android app that uses database.
When I execute it everything is OK. However when I switch the phone to mount mode I can't find the actual *.db file.
I am trying to execute following:
cd /media/
find . -name *.db
I also tried to search for the database file without success.
After playing a little with SQLite database browser I know that I need to save the file after creation.
Is there such a function in Android API?
Thank you.
If your app uses a database, it will be placed in the /data/data/<your-apps-package-name>/databases directory on your phone. To see it on the phone, I believe you need root privileges.
You should be able to pull the database locally to a connected machine which has adb installed on it. Or you can use ddms with Eclipse to pull the data to your machine.
I am working with SQLite in an App. It writes to the database, etc., with no problem. However, I can not find this new database. I have tried changing the directory with cd /data/data/packageName/databases, but it says "no such file or directory". Also, this database is not found when I click on the File Explorer in eclipse. My logging tells me the database was created and that it is being written to. I think I need to set the path in the shell or something to that effect using adb, but I have no idea how to do that. Can anyone give me some instruction? Also, I am using my phone for development. The database also does not show up when using the emulator.
Thanks very much.
Matt
Matt,
This thread gives a good explanation on why you might not be able to access the data folder on your phone.
Can't access data folder in the File Explorer of DDMS using a Nexus One!
You can still test the Sqlite code though. Just boot up an emulator. The emulator will have no access restrictions. Once it's booted up you can use the ddms tool (located in the tools directory under your android SDK install folder). It has a File Explorer and you can download the files from the /data folder.
Also, I am using my phone for development.
You cannot access the database on a standard Android device except via your own application code.
Your options are:
Do this sort of testing on an emulator, in which case you can access the directory that you are failing to access on the device
Add a database backup feature to your app, that copies the (closed) database to external storage, so you can examine it
Root your phone (leastways, I am under the impression this can help get you to this directory -- haven't done it myself)
The database also does not show up when using the emulator.
Try harder. If you can store data in the database and read data out of it using SQLiteDatabase, then the database file is there.
This question already has answers here:
Debugging sqlite database on the device
(17 answers)
Closed 5 years ago.
I am having trouble accessing the database while I am developing on the phone. Whenever I execute
cd /data/data/com.mycompck/databases
and then run ls I get: "opendir failed, Permission denied"
Or whenever I type in sqlite3 I get: "sqlite3: permission denied"
What am I doing wrong?
Are there some applications that can help me getting a human view of content resolvers values and/or SQLite databases?
Check my answer from the following thread: Why do I get access denied to data folder when using adb?
Starting from API level 8 (Android 2.2), if you build the application as debuggable, you can use the shell run-as command to run a command or executable as a
specific user/application or just switch to the UID of your
application so you can access its data directory.
So basically you will need to make a debug build (which is made automatically whenever you launch the application from the Android Studio unless you request the release build) and run the following commands:
run-as com.mycompck
cd /data/data/com.mycompck/databases
ls
sqlite3 ./yourdatabase.db
However note that sqlite3 binary is not present by default on many phones. Thus you will perhaps need to download it somewhere (e.g. from SuperOneClick archives at http://shortfuse.org/), save on the SD card and make it executable (which is a little bit tricky though), for example:
run-as com.mycompck
cd /data/data/com.mycompck/
cat /sdcard/sqlite3 >./sqlite3
chmod 744 ./sqlite3
./sqlite3 ./databases/yourdatabase.db
To answer the first part of your question, check out this answer. Basically, your phone needs to have root access, and you need to run adb in root mode (using "adb root").
As for the second part, I use SQLite Database Browser to view my SQLite dbs (though that's only when the db is on my computer; don't know of any on-device browsers). I don't know of any way to get a human view of content resolvers.
You have to be root to access any database file. So, you can either get root on your phone (look for information on Google) or debugging the database just from the emulator (wich gives you root access always).
Bye!
The best way to view and manage your android app database is to use this library https://github.com/sanathp/DatabaseManager_For_Android
Its a single java activity file ,just add the java file to your source folder you can view the tables in your app database , update ,delete, insert rows to you table .Everything from your app.
When the development is done remove the java file from your src folder thats it .
It helped me a lot .Hope it helps you too .
You can view the 1 minute demo here : http://youtu.be/P5vpaGoBlBY
I've read up on this a little and accessing your database files for mobile seems quite of a hassle.
Take a look at this. with this you can view your database inside of your application. Database Manager
For me this worked fine. It kind of also depends on what you're planning to do ofcourse.
Hope it helps.
