DragonCity File Modification - Android Q&A, Help & Troubleshooting

Hi, so I'm new with Android stuff, I would like help with something.
I've been playing Dragon City for quite a while, and I've tried to get some advantage in the game through GameGuardian by changing currency values in the game, but it does not seem to work with online-based games. So I thought of downloading a file explorer to see if I could edit files that are in the internal storage of my phone. I'm using ES File Explorer and I found something quite interesting.
When I go into the internal storage there's a folder with the name of the app which has more folders inside, there's one folder called "shared_prefs", inside there are a lot of xml files. One of this files is called "DragonCityPrefsFile.xml" which has written the data of the things I have in storage on the game. I thought that if I made some changes to this file then the game would give the new amount of things I wrote. I modified the values of the things I have but whenever I save the file and open the app again, the value changes to the original. So I assume since it's an online-based game this method won't work in any way even if I make a copy of the file, modify the values, and then replace the original file with the new one.
Here are some pictures if it helps to understand better what I'm trying to do here:
Folder Location:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Shared_Prefs folder:
XML file:
Is there any way I can modify the prefsfile.xml and then somehow replace it in the app's game folder? So for example, download the .apk and with a program compile the app with the modified prefsfile. If anyone knows a method please let met know

The server checks for ALLL XML AND DB FILES for values and You won't be able to cheat it.Your only hope is to hack the server change values and wipe their backup Drives.Also change values of a couple of thousand of other players.NoSql based servers are hard ones but with given time and patience you can crack them from a VPS

Damn, that's unfortunate. Thanks for the help mate, I'll look up for some more info about the VPS cracking, sounds interesting.
