Question How to get lego fusion town master app/game working on Sony Xperia Z

Trying to install Fusion Tower Master app on my Sony Xperia Z Tablet

But i keep getting "Your device isn't compatible with this version" message even though Xperia is android so what I did was download the apk of this game and manual install to device.

I got the apk file from online. It was 2 files in this folder com-lego-fusion-townmaster

1) main.1222.com.lego.fusion.townmaster.obb
2) com_lego_fusion_townmaster-1222.apk

Then i uploaded entire folder with those 2 files in it. In the OBB Folder in Andrioid Folder of my Xperia Z

I then installed the .apk file said completed successfully but when i launch the game i get this message

"Downlad Failed Beause You May Not Have Purchased This app". Even though app is free correct?

Is there any workaround to get this fix or working to play the game on this tablet?
