Android Studio Emulator Slow or Laggy

How to fix it

Try these in order — the most common fix is first.

1. 1. Verify acceleration

   Copy steps
   1. Run emulator -accel-check
   2. If no hypervisor is reported, enable WHPX, KVM or Hypervisor.Framework as described in the hypervisor guide
   Did this fix it? Yes No

2. 2. Use matching system images

   Copy steps
   1. Create AVDs with x86_64 images on Intel/AMD hosts and arm64-v8a images on Apple silicon
   2. Avoid running ARM images on x86 hosts
   Did this fix it? Yes No

3. 3. Pick the right graphics mode

   Copy steps
   1. Device Manager > edit AVD > Additional Settings > Emulated Performance > Graphics acceleration
   2. Try Hardware first; if you see glitches or crashes use Software
   3. Update your GPU driver; on laptops with two GPUs, make sure the discrete GPU is used
   Did this fix it? Yes No

4. 4. Reduce load

   Copy steps
   1. Close other heavy apps
   2. Add the emulator and AVD folder to antivirus exclusions
   3. Use Quick Boot snapshots; cold boot only when needed
   Did this fix it? Yes No

5. 5. Test on a real phone

   Copy steps
   1. Google notes that debugging on a physical device uses less memory than on the emulator
   2. Enable USB debugging and run the app on the phone
   Did this fix it? Yes No

Symptoms

The emulator takes minutes to boot, UI lags, apps stutter or the host machine freezes while it runs.

Why it happens

• No hypervisor active (emulation falls back to slow translation)
• Software graphics rendering chosen by 'auto'
• Too little RAM on the host or in the AVD
• Antivirus scanning emulator and snapshot files
• Old emulator version or old Intel GPU driver
• Using an ARM system image on an x86 host
