Youll see a popup window that will show you the list of virtual devices. It gives you the ability to test your Android projects across more devices than you could ever realistically hope to get your hands on.AndroidEnv - Emulator Setup Guide. At this point you can use the cordova CLI utility to deploy the application to the emulator from the command line:The emulator is one of the most powerful tools in the Android developer’s arsenal. It launches much as it would on the device, with additional controls available for hardware buttons: Deploy to Emulator. To open the emulator as a separate application, select the AVD and press Start.A seriously long time.Despite this drawback, the emulator is still the best way to test how your app translates across multiple hardware and software configurations—so there’s no getting away from the fact: sooner or later you’re going to have to boot up the emulator.The emulator has improved in recent years, so it’s nowhere near as slow as it used to be, but testing on the emulator can still be a frustrating experience, particularly if you need to keep switching between multiple Android Virtual Devices (AVDs). Better get comfortable, because the emulator takes a long time to load. Additionally, Mednafen, at its core, is a command line.However, the emulator does have one massive flaw, which becomes glaringly obvious the first time you launch it. Make sure ANDROIDSDK/emulator is in your environment path, this path contains emulator.exe 2.PS4Emux is an open source PlayStation 4 Emulator for PC,Android and IOS. How to Launch Android Emulator Using CMD 1.
![]() Warm Swap: This kind of swap is still very fast, but Instant Run will need to restart the Activity before the changes appear in your app. This is the fastest type of swap. Your app continues to run as normal and it simply loads the changes the next time the relevant method is called. Hot Swap: Instant Run can apply incremental code changes without having to relaunch your app or even restart the current Activity. In the best case scenario, your app won’t even need to restart — your code changes will appear in the running instance of your app, as if by magic.However, the way Instant Run applies your updates will vary depending on the nature of those updates and some updates are easier to apply than others: If you restart your app from the device, you won’t see any of the code changes you pushed since the last cold swap. Only start and restart your app from Android Studio, and not from the target device. You also need to set your project’s minSdkVersion set to 15 or higher.To get the best results out of Instant Run, you might want to try these additional tips and tricks: A cold swap is required for any structural changes such as adding or removing an annotation, instance field or static method signature, or changing your project’s list of implemented interfaces.To use Instant Run, you need to install the Android Plugin for Gradle version 2.0.0 or higher. Cold Swap: This swap is a bit slower, as your app is restarted (although not re-installed). Selecting ‘Android Studio’ from the toolbar, followed by ‘Preferences…’ However, if Instant Run doesn’t seem to be enabled, you can enable it manually by: If you experience this, then try adding your project folder to Windows Defender’s list of exclusions.Instant Run is enabled by default for projects that use version 2.0.0 or higher of the Gradle plugin. Some people have reported that Windows Defender Real-time Protect can cause Instant Run slowdowns. So if your build process is set to update any part of the Manifest automatically, then you should disable this behavior. Any changes to your project’s Manifest will trigger a full build and deploy cycle. Open Android Emulator Command Line Download Through TheDownload HAXM installerUnlike most of the other items you download through the SDK Manager, the HAXM driver doesn’t install automatically. Scroll down and you’ll see an ‘Intel x86 Emulator Accelerator (HAXM Installer)’ option — download it. X86 images tabTo download additional x86 system images for different versions of the Android operating system, you just need to click the corresponding ‘Download’ link.However, if you see an error message when you try to create an x86 AVD, or nothing appears in the ‘x86 Images’ tab, then you may not have the Intel Hardware Accelerated Execution Manager (HAXM) installed.To install HAXM, launch the SDK Manager and make sure the ‘SDK Tools’ tab is selected. When you’re creating a new AVD, simply select the ‘x86 Images’ tab in the ‘System Image’ window, and then choose from one of the available x86 images. If your IDE and SDK are up to date, then creating an x86 AVD is generally pretty straightforward. Enable all of the options in this window, apart from ‘Restart activity on code changes.’The Android emulator supports system images that emulate two different CPUs: ARM and Intel x86.Using an x86 system image can speed up the emulator considerably, so this is the option you’ll typically want to opt for. Winrar alternative for macAlthough ‘Use Host GPU’ used to appear in the AVD Manager, this option isn’t currently available in Android Studio, but the good news is you can still enable GPU emulation if you launch an AVD from the command line.To launch your AVD with GPU emulation enabled, create the AVD you want to use as normal. This can make the emulator run much faster.GPU Emulation is turned off by default, so you need to enable it whenever you launch an AVD. Once HAXM is installed, repeat the process of creating a new AVD – this time, you should be able to create an AVD with an x86 system image, or at least download an x86 image if none are currently available.GPU emulation (sometimes referred to as GPU acceleration) is where the emulator utilises the host machine’s GPU to accelerate drawing options. Follow the onscreen instructions to install. In the window that appears, double-click IntelHAXM.mpkg to start the installation. Virtual machine accelerationMany modern CPUs provide extensions for running virtual machines (VMs) more efficiently.You can use these extensions to run the Android emulator inside an accelerated virtual machine, which can improve the execution speed. Spend some time interacting with the AVD, and you should notice a speed improvement. My command looks like this:Cd /Users/jessicathornsby/Library/Android/sdk/toolsNext, launch the emulator you created (myemulator) with the -gpu on flag, for example:The AVD will launch with graphics acceleration enabled. Although the emulator is only doing its job ( emulating a real device), being forced to sit through a boot animation isn’t going to improve your Android project. Disable the emulator’s boot animationBy default, the emulator displays a boot animation as it starts up. And that’s it — just launch and use your AVD as normal.To stop using the virtualisation kernel driver at any point, make sure you’ve closed any x86 emulators and then run the following command in the Terminal window:Sudo /System/Library/Extensions/intelhaxm.kext/Contents/Resources/uninstall.sh 5. Machdep outputIf you’re on Linux, you can verify whether your CPU has support for Intel VT tech by running the following command:Even if your development machine supports these virtualisation extensions, they may be turned off by default, so if you encounter problems then you may need to check your computer’s documentation, in order to find out how to enable them.You’ll also need to use an x86 system image, so if you don’t already have an appropriate AVD, then create an x86-based AVD configuration now. AMD Virtualization (AMD-V, SVM) extensions (Linux only).If you’re unsure what virtualisation technologies your Mac supports, then open the Terminal and run the following command:Check the output for any of the Intel virtualisation extensions. Intel Virtualization Technology extensions (VT, VT-x, vmx).
