Your app might create files at runtime that you want to have a look at.

Follow these steps to copy them to your development machine:

1. Make sure that adb is setup properly and your device is running in developer mode. It is not necessary to root the device.

2. Open a terminal window and enter

   adb shell

3. To be able to access the app’s files enter

   run-as <package-name>

4. Look for the file your are interested in (e.g. cd into the subfolders “files” or “databases”) and copy it to the sdcard

   cp <file-name> /sdcard

5. Open a second terminal windows and copy the file to your development machine

   adb pull /sdcard/<file-name> /Users/<user-name>/Documents
