To easily download GTA San Andreas on an Android device, the safest and most straightforward method is to purchase and download it officially from the Google Play Store:

1. Open the Google Play Store on your Android device.
2. Search for "Grand Theft Auto: San Andreas" or "GTA San Andreas Definitive Edition."
3. Make sure the game is published by Rockstar Games.
4. Click the purchase button and then install the game.
5. The game will download and install automatically (size is around 1.5 to 2 GB).

Alternatively, if subscribed to Netflix, GTA San Andreas Definitive Edition is available for free download inside the Netflix app's game section. Just find the game and download it directly. Avoid downloading from unofficial third- party sites as they may risk device security or privacy. This official method ensures the game runs smoothly and safely on Android devices running versions from 9 to 16.
