I am attempting to view a database for an app I am developing, I attempted to access it via the shell, however, it seems that in my Nexus 4's 'System/xBin' folder there is no 'sqlite3' file, and therefore unable to query my database to see its contents. Is there anyway I can do this? I am aware of an Eclipse plugin, but I am using Android Studio.
For example:
>adb -s DEVICE shell
>cd data/data/PROJECT/databases
>sqlite3 mydatabase.db
>sqlite3 not found
Thanks!
Can you see the database in the emulator ?? If yes, then probably you will not be able to see the database on the device unless you are using a device which is rooted. You will able to query the database though, but you will not be able to see it through file browser in ddms or through this command. First, please check if you can see it on emulator or not.

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.
When developing for Android I prefer just working with a real device plugged in most of the time since the Android emulators are such total garbage. The one pain point is when I want to access files and sqlite databases though. I believe with the adb shell it is possible to pull the database across, but this isn't a very convenient process.
I'm wondering if there are any tools on the market that allow you to see the database in real time, even if it requires rooting a device I'm open to it.
I am afraid that there are no tools that will let you see the db real time. You will need to get the db from the device and the see it on your system. You will have to root the phone and get SuperUser permission to access app databases. The database will (after getting root) then be available in the /data/data/com.your.application/databases folder.
Hi You don't have any tools to see the database in real times. But its achievable in rooted device. If your device is rooted just install root explorer app in it. and then browse for your package name in data/data/ location. There you will find out all the internal memory files including database files. hope this helps you.
I've created an application that uses an Android SQL database. Is there any way to find this database on the Mobile Phone that the Application is installed to?
Essentially I want to then use an SQL Database Viewer to look at all the rows?
root/data/data/package/databases/database
it should be in a file like that, in the emulator you can go straight to this using the file explorer in ddms, otherwise a rooted phone and ES file explorer
if you're using the emulator you can use the adb tool in the sdk-platform folder of the android install.
something like the following:
./adb shell
#sqlite3 /data/data/com.example.package/databases/database.db
you should then be able to do your queries.
If its on a phone, then try extract the database like above and use the sqlite3 tool to query that database.
A similar question has been answered here: https://stackoverflow.com/a/4556642/450534
The same answer provided there is:
If for whatever reason, you need to access the database on the phone, you must have root access (superuser in other words) on the phone. Then you will need a file explorer that uses root permission to give you access to the system files.
If all the above exists, then you will find the application database in:
/data/data/com.yourpackage.name/databases.
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.
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.
