How to extract database of an application from android device through adb shell command?

Thanks

回答1:

Databases are stored in files, mostly on internal storage, in App's data directory like :

/data/data/com.example.myapp/mydb

so you can do

adb pull /data/data/com.example.myapp/mydb

Then you can use some software to open that file, and work with data base. To place it back:

adb push <new file> /data/data/com.example.myapp/mydb

回答2:

If you have neither SD card nor root on your device, just use adb shell.

$ adb shell
$ run-as com.your.package cat /data/data/com.your.package/databases/your_db > /storage/sdcard0/Download/your.db

Then use DDMS to pull file out.

回答3:

AFAIK you can fetch databases only from Android Emulator, not from real device (unless the device is rooted).
To do so, simply go to DDMS --> File Explorer --> data --> data --> your package name -- > databases

Your database should be inside databases folder

Once you select your database, you will see two icons on the upper tab wherein you can push or pull the database.
