Android 40 Emulator May 2026
The Complete Guide to the Android 4.0 Emulator: Reviving Ice Cream Sandwich in 2024-2025
4. Performance Characteristics
| Aspect | ARM image (default) | x86 image (rare) | |--------|--------------------|------------------| | Boot time | 3–5 minutes | 1–2 minutes | | UI smoothness | Laggy (5–15 FPS) | Moderate (15–25 FPS) | | Host CPU usage | 90–100% (single core) | 40–70% | | GPU support | No real GPU passthrough | Limited (VirGL not present) |
Observed issues:
- Touch input latency ~100–200 ms
- Animation jank (Honeycomb-style 2D compositor)
- Camera emulation is buggy (Webcam passthrough not working on ICS)
Performance benchmarks (example, median results)
- Cold boot time: 60–180 s depending on image and host hardware.
- Memory: baseline 1.5–2.0 GB RAM used by emulator.
- App launch latency: 2×–5× slower than modern emulator images in many cases.
(Actual numbers depend on host machine; treat above as indicative.)
“Your CPU does not support VT-x” (Intel) or SVM (AMD)
- Fix: Enable virtualization in BIOS/UEFI (Intel VT-x or AMD-V).
- On Windows, also disable Hyper-V if using HAXM.
Enable KVM (Linux) or Hyper-V (Windows)
- On Windows, ensure Windows Hypervisor Platform and Virtualization Platform are on.
- In Android Studio AVD, edit the virtual device’s
config.iniand add:hw.gpu.enabled=yes hw.gpu.mode=host hw.ramSize=1024
