How can I keep an app open/active no matter what on Android/AOSP? (self.askandroid)

I don't know what is wrong with my custom ROM (Paranoid Android) it is pretty much perfect it lasts all day and beyond (about 10 hrs of SOT with mid usage in my phone from 2020) and yet I struggle with the RAM management.

I am rocking a Poco F2 Pro which is EOL as of now, even when I moved from MIUI long time ago (is not that I don't like it, I just like AOSP more) one awesome feature I loved was the ability to lock an app so the aggressive MIUI RAM management would not kill it in the background, I used to pin a Reddit app for this matter, and now I want to do the same but with my Lemmy clients.

My device has 6GB of RAM and I feel that many apps reload a lot (Discord being one of them) anyway I only want to keep always active the Lemmy app now (only one at time since I use too many).

It's worth to mention that my device is rooted, so whether you know a handy trick to achieve this or with a mod I'd appreciate it... I have tried the battery restrictions feature but I don't think it is working the same as it was compared to MIUI's feature.

Normally a custom ROM handles the RAM way better than any stock ROMs because it comes with less bloatware and whatnot, but I am feeling I can only multitask 2 or 3 apps and nothing else.

I read you fellow android users!

The problem you're having may have more to do with the background process limit introduced in android 12 than with ram management. If you're on android 12 I think I remember there being an adb command that can change the limit from 32 to something else, though I may be mistaken. I think on newer versions of android you might be able to change it in developer settings. Though it's worth checking the Dev settings even if your ROM is based on android 12, since its possible the ROM changed or added options regarding the limit.

If that is in fact the problem you're having, and you find a good solution for android 12, let me know, I really need to see about fixing things on my pixel 3 so stuff like tasker and kwgt, and autonotification, don't constantly stop working 🙃

I appreciate the info, my ROM is A13 based, I have given a quick glance to developer settings but I haven't seen anything regarding that 🤔

I have found this link and it seems interesting, for both you and me:

https://github.com/agnostic-apollo/Android-Docs/blob/master/en/docs/apps/processes/phantom-cached-and-empty-processes.md#commands-to-disable-phantom-process-killing-and-tldr

I am doing test but I think things haven't changed too much.

[–] Cris_Color 2 points 1 year ago (1 children)

Sorry to hear it doesn't seem to have improved much for you, but thank you very much for the link :) I appreciate it!

[–] kratoz29 2 points 1 year ago

Actually I think it is slightly better, but I still would like more a function like MIUI had, even if I opened a heavy Android videogame the app would not be closed.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago) (1 children)

Different ROMs have different background apps management, mine too has only 6GB and more apps stay open in the background on PE and VoidUI than ArrowOS, also AOSP should have the option to lock apps in the background not just 'Pause app'

Anyway with the number of apps/methods out there that can force close apps there should be an app/method to do the opposite

[–] kratoz29 2 points 1 year ago (1 children)

What do you mean by Pause app?

[–] [email protected] 3 points 1 year ago (1 children)

in the app switcher

[–] kratoz29 2 points 1 year ago (2 children)

Huh, but that only does pause the notifications does not it?

[–] [email protected] 2 points 1 year ago

I did not know that!

[–] [email protected] 2 points 1 year ago

Yes, but its super helpful when on dates to pause all your dating apps so they don't pop up on the date causing some uncomfortable truths to be revealed :)

Can you check in DiskInfo app if your phone has ZRAM enabled?

[–] kratoz29 2 points 1 year ago (1 children)

I'm sorry where am I supposed to check that?

This is all that I get.

[–] [email protected] 3 points 1 year ago (1 children)

The swap section is ZRAM

[–] kratoz29 3 points 1 year ago (1 children)

So everything is fine there I guess.

[–] Anti_Weeb_Penguin 3 points 1 year ago (1 children)

They look preety full in your case

[–] [email protected] 1 points 1 year ago

Interesting, mine is also pretty busy. I need to enable 6GB of ram plus. Otherwise, anything below 4GB results in swap being filled to max, making most of my apps reload.

I wanted to ask how RAM plus works. Does it use 6GB of storage space as swap or 3GB of physical storage with 3GB of compressed zram totalling 6GB of swap? My device has 6GB of ram. Anything below 4GB doesn't change anything, but setting it 4 or 6 increases, swap from 3 to 4 and 6GB, respectively.

This may be still a thing, https://dontkillmyapp.com/ ; you should check it out.

[–] kratoz29 3 points 1 year ago

Yeah, I have already tried, no luck.
