Notes on Android emulator on Win 11 PC with 16 GB RAM; Related React Native and Expo Go notes

These notes are about Android emulator usage on my current Win 11,  Intel i3 12th gen processor, 16 GB RAM PC.

An older post which may not be of much use but I think I should mention it here: Notes on Android Emulator for running React Native developed app on 4 GB RAM PC.

With my React Native development work, I was frequently facing an error of APK install failing due to not having enough free storage on Android emulator. I had to uninstall previous React Native app APKs and could install only one APK at a time. Some of my notes in previous posts about my React Native project work mention that, IFIRC.

On 9 Dec. 2025, I added 4 GB to Internal storage of Android emulator - Medium Phone API 35 (only device).

It was 7168 MB earlier. I made it around 11264 MB

Procedure followed to do it:

• Android Studio -> Device Manager -> Medium Phone API 35: Clicked ⋮ (three dots)
• -> Show Advanced Settings -> "Memory and Storage" -> made it around 11264 MB -> Finish
• -> 'Wipe Data' command (From same ⋮ (three dots) menu) [***NOT*** 'Delete' command]
• 'Wipe Data' command only deletes all user data whereas 'Delete' command deletes entire AVD.

This ensured that the emulator internal storage increased. Small downside was that all user data was deleted.

Storage showed 5.6 GB used out of 16 GB total!

Signed in with a Google a/c and so the new emulator device got fully set up.

Expo Go APK can be downloaded from Android emulator option on Expo page: https://expo.dev/go

Downloaded it and installed on emulator.

The download was 177 MB. Expo-Go-54.0.6.apk [Perhaps if I had downloaded via google Play on emulator it would have been smaller download size].

IFIRC, I was able to run a tiny React Native app - img-landscape-viewer that I am doing when I have some free time - on Expo Go on Android emulator. The app worked as expected on emulator.

[Not about Android emulator but related to above]

I uninstalled old Expo Go from Samsung M21 Android phone and installed latest version from Google Play. The download was only around 45 MB

I could not find what version of Expo Go is being downloaded on Google Play.

Opened Expo Go app on phone. Settings -> App Info shows:

Client version 54.0.6

Supported SDK 54

----------

Later I came to know that Google Play has an About this app link that opens up another screen in contrast to accordian like drop down sections for App Support and Data Safety. I had missed it in my earlier quick scan. When I did follow About this app link, the next screen had to be scrolled down to App Info section which has the version number info.

On M21 phone, used Expo Go to see img-landscape-viewer app. Both Expo Go and the app worked as expected.
