Hey folks! Let's break down your questions about Android emulator images and the su tool clearly:

1. Which Android emulator images include the su tool? #

• Official Android SDK images without Google Play Services: When selecting system images in the SDK Manager, those labeled simply "Android x.x" (such as Android 11, Android 13) with no "Google Play" tag usually come pre-installed with the su tool.
• Third-party custom emulator images: Many custom builds designed for development/debugging or root testing scenarios will include the su tool by default.

2. How to check if an Android emulator image has the su tool? #

Here are straightforward verification methods:

• Test the su command directly: Launch your emulator, connect to it via adb shell, then type su. If the command succeeds and your prompt switches from $ to #, the su tool is present. If you get a su: not found error, it’s not included.
• Check system directories: In the adb shell, run ls /system/bin/su or ls /system/xbin/su. If the file exists in either location, the su tool is part of the image.

A key observation: These emulator images typically can’t have both the su tool and Google Play Services installed simultaneously. If your image includes Google Play Services, it almost certainly won’t have su; conversely, images with su generally don’t come with Google Play Services.
