Accessing database files on a non-rooted Android device can be challenging due to the inherent security restrictions. However, for developers who need to debug applications without rooting their devices, there are methods to retrieve these files using ADB commands. This guide will walk you through the process of extracting database files using the run-as command.
Method 1: Using ADB Exec-Out Command
This method is suitable for Android devices running version 5.1 and above. The adb exec-out command allows you to access files within the app’s data directory:
adb exec-out run-as debuggable.app.package.name cat databases/file > fileFor multiple files, you can use the tar command:
adb exec-out run-as debuggable.app.package.name tar c databases/ > databases.tarThese commands will create a copy of the database files on your local machine, allowing you to view and manipulate them using database tools.
Method 2: Copy Files via SD Card
If the direct method is blocked, you can copy the files to your device’s SD card and then pull them to your computer. Follow these steps:
- Open ADB shell and switch to your app’s user space:
adb shell
run-as com.example.package
chmod 666 databases/file
exitcp /data/data/package.name/databases/file /sdcard/adb pull /sdcard/file .Remember to reset the file permissions after copying:
run-as com.example.package
chmod 600 databases/fileMethod 3: Using Device File Explorer
For those using Android Studio, the Device File Explorer offers a straightforward way to access database files:
- Open the Device File Explorer in Android Studio.
- Select your device and navigate to the
data/datadirectory. - Locate your application’s package and find the databases folder.
- Right-click on the desired database file and choose the option to save it locally.
