Recreating an old game for android.

I have the APK file of old game which was abandoned and removed from app store and google play in 2016. I really liked that game, so I decide to recreate it. With some online tools I was able to view the source code file. Will I run into any issues if I decide to reskin this game and publish it on Google Play ? Will I still be banned, even though the game is not there for 6-7 years ?

Also, this game uses the version of android which was back in 2015. How can I update it to latest android version ? Thanks in advance. I am really neawbie in all of this and want an advice from old experienced members in this nihce.

First of all, why was the game suspended/removed from Playstore? If the same reason happens again in your new game, then it will not even pass the review process.

Secondly, you simply need to change the targetSdkVersion and compileSdkVersion in build.gradle file to something above 29 so you target the most recent Android Devices.
