due to the 64-bit support; I've switched from uploading APK to uploading bundle to Play Store. However I noticed that although the APK have been getting smaller, the "User data" size (view from phone's settings) have now becomes much larger. Below are an example for my app:
Using APK:
- Total: 105MB
- App size: 102MB
- User data: 504KB
- Cache: 3.21MB
Using Bundle:
- Total: 45.34MB
- App size: 5.02MB
- User data: 39.14MB
- Cache: 1.18MB
Although I can understand why the App size is much smaller (Play Store only downloads what is needed by the device), I'm curious what exactly causes the User data to becomes this large? Did Play Store treats the components needed to be downloaded as User data?
*Not sure if it's related, but the app was built by using React Native.
