To see data , the phone must be root . Samsung Galaxy S3 is not the root provider from the supplier, you need to strengthen your phone to access the internal memory / storage, you can only access the external memory / storage on your phone, i.e. sdcard
But I would advise you to use Emulator , rather, root your phone.
Here are some links about what roots, you can go through the following:

http://lifehacker.com/5789397/the-always-up+to+date-guide-to-rooting-any-android-phone
http://en.wikipedia.org/wiki/Android_rooting
But again, I would suggest using an emulator if you are not experienced enough to root and install the firmware again when you do not want your phone root.
Use Emulator to see data->com.package
In the menu Windows-> ShowView-> Others-> android-> fileExplorer you can see the file on your device
Specify permission in AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
