Now that you know how it works, here’s a brief introduction to the most popular Android emulator out there.Īndroid Emulator (by Android Developer Studio) With hardware-acceleration, the Android emulator can run virtual devices at speeds similar to that of your workstation CPU.
UPDATE ANDROID STUDIO EMULATOR INSTALL
If your CPU supports it, the Android emulator prompts you to enable or install the hypervisor in order to speed up virtual device performance. X86 Android ABIs (Application Binary Interface, or system images) are now available to support hardware-acceleration on most computers. There’s KVM (Kernel-based Virtual Machine) for Linux. Intel’s HAXM (Hardware Acceleration Execution Manager) is a hypervisor component for Windows and macOS. This is called hardware-assisted virtualization. How it works: When the guest and the host devices have same instruction architecture (say, x86 Android system images and x86 Intel processor), QEMU skips the ‘binary translation’ part and runs the guest device directly on the host CPU. With the release of version 25.3.0, Developer Studio upgraded their emulator to support hardware-assisted virtualization. Thankfully, it can be skipped if the guest and the host CPU architectures are the same, with the help of a hypervisor.īefore 2017, Android Developer Studio’s emulator had to translate Android’s ARM architecture to match the Intel/AMD architectures commonly used in PCs. The translation of CPU architectures is a complex, time-consuming process which makes emulation almost painfully slow. You equip this with with an OS and run it like a program on your computer. Then it translates the Application Binary Interface (ABI) of the guest device to match that of the host device. How it Works: It mimics guest device hardware.
QEMU powers most Android emulators (including the one by Android Developer Studio).
It can run on a large variety of host (workstation) CPUs/OSs and emulate an even larger range of guest CPUs/OSs. It’s an open-source and incredibly versatile tool.
UPDATE ANDROID STUDIO EMULATOR SOFTWARE
Complete platform-virtualization (hardware and software emulation) is possible with Quick Emulator (QEMU).
