the one thing linux really hasnt been made on par with winblows yet is the dreadful amount of options for android simulation -the most popular choice seems to be Waydroid, but its such an unneeded hassle to set up at all -genymotion is just slow -and than you have things like android x86 which entirely defeat the point of an emulator

      What would you put in the VM? Each Android ROM is highly hardware dependent and each device’s internal storage is highly fragmented into a couple dozen partitions configured in proprietary formats.

      Theoretically a GSI ROM is supposed to be hardware-independent thanks to Treble but you would still need a common base to go with any GSI ROM and I’m not sure a generic one has been made specifically for use in a VM.

        Android x86 and derivatives are as generic as possible, like any other linux ISO you can flash it to most any computer assuming the kernel is new enough, Bliss OS is up to date with the latest LTS kernel based on xanmod, and android 12L

      nearly all android emulators are VMs, usually vbox, common ones include bluestacks memuplay. WSA uses hyper-v infranstructure. GooglePlay Games uses crosvm

          There’s a bit more to an emulator than simply running Android on x86 hardware.

            not really no. I mean, sure you could add a fancy gui on top of it. but 90% of android emulators are some kind of android x86 + libhoudini/ndk + vmm. some modify surfaceflinger so that each application will render to it’s own window, but usually it’s just disabling launcher, and sending some kind of command to open the app from a gui (IE. sending adb launch commands)

              Yes and no.

              In general it is true that an emulator just needs to translate instructions, but for things like games and the Android operating system, your emulator also needs to use whatever hardware acceleration you have or it will run like dogshit.

              Android makes extensive use of graphical acceleration to the point where it is a mandatory requirement. There is no part of the UI that doesn’t use hardware acceleration.

              Luckily Android uses OpenGL ES, and there are means to translate that into Vulkan without too much issue.

              But what you’re talking about is virtualisation for the most part - the only thing arguably doing any actual emulation in your scenario is libhoudini. Otherwise, there isn’t any translation of instructions - The Android VM instructions get executed directly on Ring 0 of the CPU

                whatever hardware acceleration you have or it will run like dogshit.

                and? vbox, qemu, hyperv and vmware, all have gpu acceleration to a degree. Qemu will also be getting vulkan acceleration soon

                EDIT: forgot crosvm (google play games) which does too

                  And therefore it means that in addition to doing translation work, they themselves need to implement hardware acceleration. That’s why you see many game emulators requiring DirectX even if the console in question never used it.

                  Oh, and 4 of the 5 products you mentioned are not emulators. Of the 5, only QEMU is fully capable of emulation. There is a massive and important difference between virtual machines and emulation.

                    nearly every single emulator, for Windows is a VM pretty much. Blue stacks, memuplay, WSA, Google Play games.

                    no, there is no difference between virtualization and emulation. virtualizations just hardware accelerated emulation. That’s it. If you use blue stacks and call it emulation, because it’s emulation, all the sudden it’s not emulation because it’s virtualization?

                    If that is the bar, then there are incredibly few Android emulators. Yes some Android emulators, or rather virtualizers, do implement some custom GPU acceleration stuff. but not all, Google Play games uses CrossVM with vulkan cereal, WSA uses their weird stack. genymotion IIRC uses virgl, so does qemu.

                    EDIT: by the way, with VirtualBox VMware so and so forth, you are still emulating. you are emulating NICs, oftentimes you are emulating GPU, you are emulating storage controllers, you are emulating PCI controllers, so on and so forth.
