I'm using xamarin forms to develop an Android app. I can save a file via
var fileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), $"appsettiings.txt");
var data = JsonConvert.SerializeObject(this);
File.WriteAllText(fileName, data);
When I debug I can see that the file should be stored at
/data/user/0/<applicationame>/files/.local/share/appsettiings.txt
I like to see if the file is actually saved and what the content is. I opened the Android device monitor but the data folder was 'empty'. From some other SO case I took that I should but myself in root-mode by executing
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb root
Now the data folder contains data and I can drill down up to the files folder, but that one seems to be empty.
When I run the app again and check in code if the file exists, it actually does.
Any further suggestions how to get access to that file from any tooling. I want to delete that file and run the app again.
You can use adb pull to copy the file to local machine and look at it content like this:
adb root
adb pull /data/user/0/<applicationame>/files/.local/share/appsettiings.txt [LOCAL_FOLDER]
then you can use adb shell then rm -f to remove it, like this:
adb shell
su
rm -f /data/user/0/<applicationame>/files/.local/share/appsettiings.txt
Since the file you are requesting is inside /data folder, you need to have the corresponding root priviliege to get it, so you need to do adb root before the adb pull command, and you need to do su before removing the file.
If I am not mistaken, if you save a file with your approach, it should exist, as you already proofed with the .Exists method.
I am not quite sure, are you just trying to read the content out of the file? Or do you want to access it from outside of the application?
If your desire is to just read the content, you could access it with
string content= File.ReadAllText(your file path);
and set a breakpoint (F9) on the next line.
I use Room database to build my app.
After i create my database how i pull the database file with the following adb command:
adb exec-out run-as ---.---.--- cat /data/data/---.---.---/database/user-database.db > MyDB.db
Then when i try to oped that MyDB.db file with sqlitebrowser i see the message "Invalid file format".
Why i can not open that file?
Is there an other better way to pull and examine the database file created by Android Room ??
Thank you
In Android Studio 3, there is Device File Explorer at the right side (for me).DeviceFileExplorer photo
Click it and go to your database file. for me, data> data> myPackageName> databases> location of database file

Debugging sqlite database on the device
(17 answers)
Closed 5 years ago.
I have a set of data in an SQLite database. I need to view the database on a device. How do I do that?
I have checked in ddms mode. The data in file explorer is empty.
Here are step-by-step instructions (mostly taken from a combination of the other answers). This works even on devices that are not rooted.
Connect your device and launch the application in debug mode.
You may want to use adb -d shell "run-as com.yourpackge.name ls /data/data/com.yourpackge.name/databases/" to see what the database filename is.
Notice: com.yourpackge.name is your application package name. You can get it from the manifest file.
Copy the database file from your application folder to your SD card.
adb -d shell "run-as com.yourpackge.name cat /data/data/com.yourpackge.name/databases/filename.sqlite > /sdcard/filename.sqlite"
Notice: filename.sqlite is your database name you used when you created the database
Pull the database files to your machine:
adb pull /sdcard/filename.sqlite
This will copy the database from the SD card to the place where your ADB exist.
Install Firefox SQLite Manager: https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/
Open Firefox SQLite Manager (Tools->SQLite Manager) and open your database file from step 3 above.
Enjoy!
UPDATE 2020
Database Inspector (for Android Studio version 4.1). Read the Medium article
For older versions of Android Studio I recommend these 3 options:
Facebook's open source [Stetho library] (http://facebook.github.io/stetho/). Taken from here
In build.gradle:
dependencies {
// Stetho core
compile 'com.facebook.stetho:stetho:1.5.1'
//If you want to add a network helper
compile 'com.facebook.stetho:stetho-okhttp:1.5.1'
}
Initialize the library in the application object:
Stetho.initializeWithDefaults(this);
And you can view you database in Chrome from chrome://inspect
Another option is this plugin (not free)
And the last one is this free/open source library to see db contents in the browser https://github.com/amitshekhariitbhu/Android-Debug-Database
The best way I found so far is using the Android-Debug-Database tool.
Its incredibly simple to use and setup, just add the dependence and connect to the device database's interface via web. No need to root the phone or adding activities or whatsoever. Here are the steps:
STEP 1
Add the following dependency to your app's Gradle file and run the application.
debugCompile 'com.amitshekhar.android:debug-db:1.0.0'
STEP 2
Open your browser and visit your phone's IP address on port 8080. The URL should be like: http://YOUR_PHONE_IP_ADDRESS:8080. You will be presented with the following:
NOTE: You can also always get the debug address URL from your code by calling the method DebugDB.getAddressLog();
To get my phone's IP I currently use Ping Tools, but there are a lot of alternatives.
STEP 3
That's it!
More details in the official documentation:
https://github.com/amitshekhariitbhu/Android-Debug-Database
The best way to view and manage your Android app database is to use the library DatabaseManager_For_Android.
It's a single Java activity file; just add it to your source folder.
You can view the tables in your app database, update, delete, insert rows to you table. Everything from inside your app.
When the development is done remove the Java file from your src folder. That's it.
You can view the 5 minute demo, Database Manager for Android SQLite Database .
You can do this:
adb shell
cd /go/to/databases
sqlite3 database.db
In the sqlite> prompt, type .tables. This will give you all the tables in the database.db file.
select * from table1;
If you are using a real device, and it is not rooted, then it is not possible to see your database in FileExplorer, because, due to some security reason, that folder is locked in the Android system. And if you are using it in an emulator you will find it in FileExplorer, /data/data/your package name/databases/yourdatabse.db.
Try AndroidDBvieweR!
No need for your device to be ROOTED
No need to import the database file of the application
Few configurations and you are good to go!
I have been using SQLite Database Browser to see the content SQLite DB in Android development. You have to pull the database file from the device first, then open it in SQLite DB Browser.
Although this doesn't view the database on your device directly, I've published a simple shell script for dumping databases to your local machine:
https://github.com/Pixplicity/dbdump
It performs two distinct methods described here:
First, it tries to make the file accessible for other users, and attempting to pull it from the device.
If that fails, it streams the contents of the file over the terminal to the local machine. It performs an additional trick to remove \r characters that some devices output to the shell.
From here you can use a variety of CLI or GUI SQLite applications, such as sqlite3 or sqlitebrowser, to browse the contents of the database.
Follow these steps
1>Download the *.jar file from here .
2>Put the *.jar file into the folder eclipse/dropins/ and Restart eclipse.
3>In the top right of eclipse, click the DDMS icon.
4>Select the proper emulator in the left panel.
5In the File Explorer tab on the main panel, go to /data/data/[YOUR.APP.NAMESPACE]/databases.
6>Underneath the DDMS icon, there should be a new blue icon of a Database light up when you select your database. Click it and you will see a Questoid Sqlite Manager tab open up to view your data.
*Note: If the database doesn't light up, it may be because your database doesn't have a *.db file extension. Be sure your database is called [DATABASE_NAME].db
*Note: if you want to use a DB without .db-Extension:
-Download this Questoid SqLiteBrowser: Download fro here.
-Unzip and put it into eclipse/dropins (not Plugins).
-Check this for more information

step 1
Copy this class in your package
step 2
put the following code in your class which extends SQLiteOpenHelper.
//-----------------for show databasae table----------------------------------------
public ArrayList<Cursor> getData(String Query)
{
//get writable database
SQLiteDatabase sqlDB =this.getWritableDatabase();
String[] columns = new String[] { "mesage" };
//an array list of cursor to save two cursors one has results from the query
//other cursor stores error message if any errors are triggered
ArrayList<Cursor> alc = new ArrayList<Cursor>(2);
MatrixCursor Cursor2= new MatrixCursor(columns);
alc.add(null);
alc.add (null);
try{
String maxQuery = Query ;
//execute the query results will be save in Cursor c
Cursor c = sqlDB.rawQuery(maxQuery, null);
//add value to cursor2
Cursor2.addRow(new Object[] { "Success" });
alc.set(1,Cursor2);
if (null != c && c.getCount() > 0)
{
alc.set(0,c);
c.moveToFirst();
return alc ;
}
return alc;
}
catch(SQLException sqlEx)
{
Log.d("printing exception", sqlEx.getMessage());
//if any exceptions are triggered save the error message to cursor an return the arraylist
Cursor2.addRow(new Object[] { ""+sqlEx.getMessage() });
alc.set(1,Cursor2);
return alc;
}
catch(Exception ex)
{
Log.d("printing exception",ex.getMessage());
//if any exceptions are triggered save the error message to cursor an return the arraylist
Cursor2.addRow(new Object[] { ""+ex.getMessage() });
alc.set(1,Cursor2);
return alc;
}
}
step 3
register in manifest
<activity
android:name=".database.AndroidDatabaseManager"
android:screenOrientation="portrait"
android:theme="#style/AppTheme.NoActionBar"/>
step 4
Intent i = new Intent(this, AndroidDatabaseManager.class);
startActivity(i);
This works with Android 6.0 (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 try SQLiteOnWeb. It manages your SQLite database in the browser.
Hope this helps you
Using Terminal First point your location where andriod sdk is loacted
eg: C:\Users\AppData\Local\Android\sdk\platform-tools>
then check the list of devices attached Using
adb devices
and then run this command to copy the file from device to your system
adb -s YOUR_DEVICE_ID shell run-as YOUR_PACKAGE_NAME chmod -R 777 /data/data/YOUR_PACKAGE_NAME/databases && adb -s YOUR_DEVICE_ID shell "mkdir -p /sdcard/tempDB" && adb -s YOUR_DEVICE_ID shell "cp -r /data/data/YOUR_PACKAGE_NAME/databases/ /sdcard/tempDB/." && adb -s YOUR_DEVICE_ID pull sdcard/tempDB/ && adb -s YOUR_DEVICE_ID shell "rm -r /sdcard/tempDB/*"
You can find the database file in this path
Android\sdk\platform-tools\tempDB\databases
Using file explorer, you can locate your database file like this:
data-->data-->your.package.name-->databases--->yourdbfile.db
Then you can use any SQLite fronted to explore your database. I use the SQLite Manager Firefox addon. It's nice, small, and fast.
There is TKlerx's Android SQLite browser for Eclipse, and it's fully functional alongside Android Studio. I'll recommend it, because it is immensely practical.
To install it on Device Monitor, just place the JAR file in [Path to Android SDK folder]/sdk/tools/lib/monitor-[...]/plugins.
I found very simple library stetho to browse sqlite db of app in chrome, see
First post (https://stackoverflow.com/a/21151598/4244605) does not working for me.
I wrote own script for get DB file from device. Without root. Working OK.
Copy script to directory with adb (e.g.:~/android-sdk/platform-tools).
Device have to be connected to PC.
Use ./getDB.sh -p <packageName> for get name of databases.
Usage: ./getDB.sh -p <packageName> -n <name of DB> -s <store in mobile device> for get DB file to this (where script is executed) directory.
I recommend you set filename of DB as *.sqlite and open it with Firefox addon: SQLite Manager.
(It's a long time, when i have written something in Bash. You can edit this code.)

I think this question has been asked, however I have tried several of the examples to no avail. My issue is this ... I have an Android app setup to use the SQLCipher DB encryption, which works fine, on the device.
In testing on an emulator, if I download the Database file using the DDMS, how do I read that file to check tables and data? I have tried using the command shell for SQLite3, and the ATTACH examples, however each time I do so, I just get the following message 'Error: file is encrypted or not a database'. This certainly shows that the ENCRYPT is working, but how I do I properly DECRYPT outside the emulator/eclipse?
Do I need a different SQLite client? Anyone else get stuck on this?
I a using: SQLCipher for Android 2.0.8 06/14/2012
Any help? Thanks
The "normal" SQLite tools do not include SQLCipher.
You have to download the souce and compile it yourself to get a command shell with SQLCipher support.
I resolved this by using this small script.
decrypt.sh
#!/bin/bash
# Bashscript to decrypt databases
echo "pull db from device.."
adb pull /data/data/com.example/databases/database.db
echo "removing previous decrypted db, if existent.."
rm -r decrypted_database.db
echo "decrypting database.db into decrypted_database.db"
sqlcipher -line database.db 'PRAGMA key = "encryption_key";ATTACH DATABASE "decrypted_database.db" AS decrypted_database KEY "";SELECT sqlcipher_export("decrypted_database");DETACH DATABASE decrypted_database;'
These programs should be added to your PATH:
adb
sqlcipher
Replace in script:
com.example with your packagename
database.db with name databasefile
encryption_key with encryption password
Can somebody help me to see the values that are stored in a database non-programatically? Using file explorer and command prompt?
using command line
a) enter adb shell
b) cd to your app directory, database file will under databases folder
c) $sqlite3 yourdb_name
d) ## now you should enter command mode
e) select * from your_tablename;
using ddms
a) using DDMS's file explorer
b) find the database file
c) copy databases to ypur PC
d) use any sqlite tool to read it
Good luck!!
use sqlitebrowser
You can use the command line tool sqlite3(.exe) of the SQLite library.
Source: http://www.sqlite.org/sqlite.html
download sqlite browser and browse your data and you can see its tables and its data use this blog to learn more.
Is it possible to get the Database from the DDMS in eclipse?
I was searching in the data folder for the application and I didn't find it there.
