Android Studio plus an emulator is one of the heaviest common dev setups. 16GB is the floor, 32GB is where it stops fighting you.

Quick answer
Android Studio realistically needs a 16GB machine minimum and is genuinely comfortable at 32GB. The IDE and Gradle typically take 3–6GB, the Android Emulator wants 2–4GB of its own, and the OS plus browser take the rest. On 8GB it technically runs — with the emulator closed and a physical device used for testing instead.
Where the memory goes
| Component | Typical use |
|---|---|
| Windows/macOS + background apps | 4–6GB |
| Android Studio (IDE + indexing) | 2–4GB |
| Gradle daemon & builds | 1–3GB |
| Android Emulator (per AVD) | 2–4GB allocated |
Making 16GB work well
- Cap the emulator’s RAM at 2GB for API testing; use a physical device for heavy testing.
- Raise Studio’s heap only if you have headroom: studio.vmoptions -Xmx2048m is sensible at 16GB; 4096m at 32GB.
- Set Gradle’s org.gradle.jvmargs=-Xmx2g in gradle.properties — bigger is not better on a tight machine.
- Close Chrome’s tab hoard during builds; the browser is the silent competitor.
Buying advice
If Android development is your job or degree focus and you are buying a laptop, 32GB (or an upgradeable 16GB model) is the spec to prioritise after an SSD. Soldered 16GB machines work, but they are the ceiling, not a starting point. General dev numbers: RAM for programming.
Frequently asked questions
Why is Android Studio using RAM even when idle?
Indexing, the Gradle daemon staying warm for faster builds, and cached project models. It releases under system pressure — high ‘in use’ with a warm daemon is by design.
Emulator or physical device on a low-RAM machine?
Physical device, every time. It removes the emulator’s 2–4GB and is a truer test of performance anyway.
