copy db file with adb pull results in 'permission denied' error

Question

I just rooted my Nexus 5 using this method: http://www.phonearena.com/news/How-to-root-Google-Nexus-5_id49014

I also enabled USB debugging in the developer options.<

Answer 1

@guest-418 tips works well:

adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db

However, if you want to use a GUI, use Android Studio's Device File Explorer.

1. Launch Android Studio

2. Click on Device File Explorer at bottom right-side Navigate to your app's file:

   /data/data/path.to.package/databases/data

3. Right-mouse click select Save As and save to a local folder

I have been having Android Monitor hang on me lately on macOS. Device File Explorer works well for this purpose.
