Question

Has anyone else experienced pretty dramatic memory issues with Android Studio lately The memory indicator sits happily at 2 6MB Ive set the limit to 12MB but my system tells me Android Studio uses up almost 40 MB Im on the latest canary but this has been happening for quite a while months

Jakub Syty · Answer

Oh man i wish android studio used 40 MB Even 100 Even 500

Jakub Syty · Answer

on the serious note i assume you are talking about GB not MB

Jakub Syty · Answer

system tells you about virtual memory usage it s not a physical RAM usage

Jakub Syty · Answer

My take on it if it works for you if you do not have any performance issues or crashes is it really an issue

Jakub Syty · Answer

RAM is there to use it

Jakub Syty · Answer

it s like chrome Yes it uses a lot of ram but at the same time it is the fastest browser So for me it s worth it It s not like i need this ram for later

Zoltan Demant · Answer

Whoops yes GB smile And the usage unfortunately results in terrible UX I can still code mostly fine but the emulator lags a ton

Jakub Syty · Answer

What is your machine

Jakub Syty · Answer

emulator often lags for other reasons

Jakub Syty · Answer

and emulator probably won t show up in the same process as android studio

Zoltan Demant · Answer

Maybe Im coming at this from the wrong perspective its just that the high memory usage seems to 100 correlate with the lag Ive rebooted to fix this a few times but it seems that I can even just restart AS to fix it The emulator is usually very fast for me even in debug builds Im working with compose My machine runs Windows i9 with 64GB RAM

Jakub Syty · Answer

hmm

Jakub Syty · Answer

maybe you gradle config version whatever makes some leak I m working on windows with 32 GB of RAM on really big projects and no such issues

Zoltan Demant · Answer

Thats what Im used to as well Which version of AS are you using I wouldnt even know where to start looking for the leak in my case Im sort of hoping that its just a generic issue with AS but I also think its been happening for far too long for that to be 100 true

rocketraman · Answer

The emulator is a different process than Android Studio so if that is lagging your system may just be short on memory You may want to actually try limiting Studio s memory a bit more with a ` Xmx` parameter In IntelliJ its under Help Edit Custom VM Options Not sure where it is in Studio

Jakub Syty · Answer

I m always sticking with stable version no need for unnecessary drama in my life smile

Jakub Syty · Answer

< rocketraman> with 64GB of ram this probably isn t an issue And Zoltan said that he did limit the memory usage in settings which is pretty much setting those flags

rocketraman · Answer

Right I missed that But at the end of the day his problem seems to be mostly with emulator which really has nothing to do with Studio except indirectly He ll need to dig into Task Manager Perfmon to perhaps get hints as to why emulator is lagging If Studio is using 40 GB of virtual memory and his system is paging that could slow the emulator down a lot

rocketraman · Answer

Also what are the emulator device RAM sizes set to

rocketraman · Answer

I have 128 GB of RAM on my system and I ve had runaway processes use it all up So 64 GB is no guarantee of available memory

Zoltan Demant · Answer

Emulator RAM is the default Ive been using the same emulator for years heart Maybe tweaking that will help Ill check

Zoltan Demant · Answer

Thank you smiley I had it set to 2048 MB so I doubled it and its much smoother despite earlier problems How much RAM have you allocated to the emulator yourselves

rocketraman · Answer

Mine is at the default and it seems to work ok shrug

Zoltan Demant · Answer

If it aint broken On the other hand maybe it will work even better with an increase Either way happy and snappy here thanks for all the help slightly smiling face
