Exclamation How to Give an App Higher priority?


So there are a few apps which I want staying in memory. I.E. I don't want Android to kill it. Is there such an app that can do this and if not, is there a script? I believe Super Charger? If Super Charger, how do I use it?

To summarize, I want a few apps (the phone, the messaging, true caller, and ex dialer) to get highest priority/never die.

Is this possible?
