Is it possible to achieve the maximum performance of a single application, even if it takes up most of the resources?

Question

Android

Greetings.
I must say right away that I have practically no idea about mobile development,
I ask you not to kick much.
It is known that android applications in the "inactive / minimized" form remain in RAM, but the response (opening the application when you "tap" on it) occurs with a delay.
Why is it so? I tried to understand the manual , but I didn’t understand anything, it seems that the application is not fully loaded into RAM ...
And is it possible then to transfer the application completely to RAM?
(all the same, in 90% of cases employees use only one device on the device) the way it can be done in linux systems, for example, transfer the browser cache ( psd programif anyone is interested).
It is likely that I am looking in the wrong direction at all, and the response of the application depends on other factors.
In general, is it possible (albeit theoretical) to achieve the maximum speed of performance of one application, even if it takes up most of the resources?

Answer 1

nope, without root. You can force to initially use a large heap or acceleration there. It's all.
If you really need it, then see https://github.com/rovo89/XposedBridge/wiki/Develo... I didn’t write it myself, but, theoretically, you can use a hook to prevent the application from being deleted from RAM.
