I think Moonbase Inc does not involve raiding.
Personally I didn't enjoy it too much so I can't say more about it.
Also there aren't many basebuilding games for android I believe :(
Here are the games I've currently got, that I consider Simulation (either because Google Play says they're a simulation game or because I mentally said 'fuck google, this is clearly a simulation game).
Link me: Interstellar, MoonBase Object, Plague Inc, Star Command.
EDIT: Apparently even though it is called MoonBase Object when you start it up, it is called Moonbase Inc on the Play Store.
As much as Kairosoft games are the no doohickey Sherlock choice; I still found some others.
Moonbase Inc. - https://play.google.com/store/apps/details?id=jeu.de.marc
You run a Space Colony on the Moon. It has an abysmal user interface and an ambiance too silent; which is a HUGE turn-off but it might be worth bypassing through it if you really want to.

Its a simple and decent city building game that takes place in France under a civil war. The whole game is mission based, but you can set up a sandbox mode and determine the size and the number of Enemies in one setting. Its technically worth the asking price, but its also very bare bones and you've experienced the most this game offers when you set up the largest map and the highest amount of enemies.
If you're wondering where the 1st to 5th entries are; then they're on a mobile java phone...including this one.
moonbase inc is the only one I've found. it's free, no iap, and it's actively being developed.
If you are into builder games, Moonbase Inc is pretty decent.
