android adb, retrieve database using run-as

Question

On a non-rooted android device, I can navigate to the data folder containing the database using the run-as command with my package name. Most files types I am content with just viewing, but with the database I would like to pull if from the android device.

Is there a download copy or move command from this part of adb shell? I would like to download the database file and view its content using a database browser.

One answer here involves turning entire application package into a compressed archive, but there is no further answer on how to extract that archive once this is done and moved to the machine, leaving me very sidetracked when there might be a more direct solution to begin with

Answer 1

By design user build of Android (that's what you have on your phone until you unlock the bootloader and flash the phone with userdebug or eng software) restricts access to the Internal Storage - every app can only access its own files. Fortunately for software developers not willing to root their phones Google provides a way to access the Internal Storage of debuggable versions of their packages using run-as command.

To download the /data/data/debuggable.app.package.name/databases/file from an Android 5.1+ device run the following command:

adb exec-out run-as debuggable.app.package.name cat databases/file > file

To download multiple files in a folder under the /data/data/debuggable.app.package.name/ at once - use tar:

adb exec-out run-as debuggable.app.package.name tar c databases/ > databases.tar
adb exec-out run-as debuggable.app.package.name tar c shared_prefs/ > shared_prefs.tar

Answer 2

Much much simpler approach to download the file onto your local computer:

In your PC shell run:

adb -d shell 'run-as <package_name> cat /data/data/<package_name>/databases/<db_name>' > <local_file_name>

Answer 3

If anyone looking for pulling database from debug application may use the procedure below:

1. search and open device file explorer

2. Select your handset and then browse to data/data directory

3. Now find your application package and go to databases folder. You can see the databases there and upon right click, you will get option to save this in your drive.

Answer 4

I've published a simple shell script for dumping databases:

https://github.com/Pixplicity/humpty-dumpty-android

It performs two distinct methods described here:

1. First, it tries to make the file accessible for other users, and attempting to pull it from the device.
2. 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.
