How to access data/data folder in Android device?

Question

I am developing an app and I know my database *.db will appear in data/data/com.****.***

I can access this file from AVD in Eclipse with help of sqlite manager

But I can't access this file in my Android phone.
I google it and it says I need to root my phone to do it, but I don't want to do it. (New phone, warranty issues, and security issues)

So here is my question: How can I access my data/data/..... directory in my Android phone "without rooting it"?

Can I change user permissions for the directory data/data..... without rooting it?

Answer 1

Accessing the files directly on your phone is difficult, but you may be able to copy them to your computer where you can do anything you want with it. Without rooting you have 2 options:

1. If the application is debuggable you can use the run-as command in adb shell

   adb shell
   run-as com.your.packagename 
   cp /data/data/com.your.packagename/
   

2. Alternatively you can use Android's backup function.

   adb backup -noapk com.your.packagename
   

   You will now be prompted to 'unlock your device and confirm the backup operation'. It's best NOT to provide a password, otherwise it becomes more difficult to read the data. Just click on 'backup my data'. The resulting 'backup.ab' file on your computer contains all application data in android backup format. Basically it's a compressed tar file. This page explains how you can use OpenSSL's zlib command to uncompress it. You can use the adb restore backup.db command to restore the backup.
