not only to machine RAM capacity but also to RAM limit set in Intel® Hardware Accelerated Execution Manager (Intel® HAXM). - In the past you had to download HAXM from Intel official website. Now you can do it from Android Studio. RAM limit is set during installation. - First statement is not really true. If you start all AVD in the same moment RAM limit won’t kick in. e.g. you can start even 10 AVD at the same time with 2GB RAM limit. Don’t do it, your machine will simply restart from OOM.

you answer `yes` then you will be asked 52 low level questions about where to store cache, where to allocate memory during AVD initial boot, networking, CPU properties and so on… $ avdmanager create avd --name "testAVD" --package "system-images;android-26;google_apis;x86" --abi "google_apis/x86" Do you wish to create a custom hardware profile?

| avdmanager create avd --name "testAVD" --package "system-images;android-26;google_apis;x86" --abi "google_apis/x86" But if you are scripting, then you can make it simpler in my opinion. First of all you don’t need to bother with those answers. How to handle AVD config?

with ‘emulator-port’ name format. - When you create new AVD you want to be able to interact with it and monitor it’s behaviour. If you know port of AVD you have started then you know how to interact with it. Port is a reference to your AVD in ADB. - Google recommends to start AVD on port range 5554 - 5586 so you want to see if those ports are free.

AVD_NAME -port AVD_PORT Optional but very helpful parameters: AVD_PORT - port on which AVD will run. Only way to have reference to created AVD from code. Takes 4 digit int value e.g. 5554.
AVD_NAME -port AVD_PORT -no-boot-anim Optional but very helpful parameters: AVD_PORT - port on which AVD will run. Only way to have reference to created AVD from code. Takes 4 digit int value e.g. 5554 -no-boot-anim - disables boot animation during emulator startup for faster booting
AVD_NAME -port AVD_PORT -no-boot-anim -gpu on Optional but very helpful parameters: AVD_PORT - port on which AVD will run. Only way to have reference to created AVD from code. Takes 4 digit int value e.g. 5554 -no-boot-anim - disables boot animation during emulator startup for faster booting -gpu on - makes use of machine GPU to render graphics - speed ups AVD performance
AVD_NAME -port AVD_PORT -no-boot-anim -gpu on -memory AVD_MEMORY Optional but very helpful parameters: AVD_PORT - port on which AVD will run. Only way to have reference to created AVD from code. Takes 4 digit int value e.g. 5554 -no-boot-anim - disables boot animation during emulator startup for faster booting -gpu on - makes use of machine GPU to render graphics - speed ups AVD performance AVD_MEMORY - possibility to extend or decrease memory usage by AVD e.g. -memory 2048
AVD_NAME -port AVD_PORT -no-boot-anim -gpu on -memory AVD_MEMORY -wipe-data -initdata AVD_MEMORY_IMAGE Optional but very helpful parameters: -wipe-data - resets emulator memory -> it resets userdata-qemu.img (current memory state) file to userdata.img (initial memory state) state -initdata - Allows to specify new path to memory image. File under path becomes new userdata.img. But userdata.img is used only on first AVD boot or after using -wipe-data. Therefore -initdata should be always used with -wipe-data. AVD_MEMORY_IMAGE - absolute path to AVD memory image
You can start AVD, change any option you like e.g language, set VPN, disable animations, setup pin or fingerprint (if you need to test that) etc. 2. Turn off AVD and copy userdata-qemu to create reusable AVD memory state.
