Here's what I tried:

  • adb shell "run-as my.package ..." doesn't work because the app was installed without the android:debuggable option.

  • adb backup doesn't work (it produces an empty file)

  • I can't use the app to copy the database to sdcard, since I'm using a new computer which has a different signature (then, AndroidStudio asks to reinstall the app)

Do I have any option to extract the database?

    You need to root your device or at least create a NANDroid Backup

  • Impossible without rooting.
