Final answer:
To install a system image on an emulated phone, choose the Android version that matches your development or testing needs, such as Android 9.0 (Pie), 10.0 (Q), 11.0 (R), or 12.0 (S), each corresponding to different API levels.
Step-by-step explanation:
The subject of your question is related to installing an emulated phone system image within an emulator. When setting up an emulator, you can choose from different versions of the Android operating system. Which specific version to install—be it Android 9.0 (Pie), Android 10.0 (Q), Android 11.0 (R), or Android 12.0 (S)—depends on your development or testing needs. Each system image corresponds to a different level of the Android API, and you would choose the one that matches the API level you want to test or use for your apps.
For example, if you are developing an application that targets Android 11.0 features, you would install the Android 11.0 (R) system image on your emulator. This allows you to test how your app behaves in that specific environment.
