Package signatures do not match previously installed version even using the same keystore

[anarkrypto]

Summary

I use eas to launch my app on play store.

After installing from the Play Store on my emulator, I can't update it using expo run:android, even though I copy the eas keystore to my project and link with credentials.json

Changing the variant from debug to release doesn't work either

adb uninstall com.package.name solves, but I wish it wasn't necessary to remove the application, just launch a new release locally, reusing the state, before publishing.

I don't know if this is an Android limitation, but the error doesn't seem to make sense to me, since the keys used for signing are the same.

Reproducible demo or steps to reproduce from a blank project

1. Build with eas build --platform android, export to Play Store and install in your device ( I am using Android Emulator).
2. Export your keystore.jks from your project Credentials in https://expo.dev/
3. Save the file in your project root
4. Paste your keyStorePassword, keyAlias and keyPassword in credentials.json in your project root

{
    "android": {
        "keystore": {
            "keystorePath": "keystore.jks",
            "keystorePassword": "xxxxxx",
            "keyAlias": "xxxxxx",
            "keyPassword": "xxxxxx"
        }
    }
}

5. Increase your app.json expo.android.versionCode
6. Run: expo run:android

Hi @anarkrypto! It's possible that you've installed a production build, using a different keystore than you would use locally (through expo run:android).

I would personally recommend using a different android.package for development/staging builds and for production. By doing that, you can install the production app (from the Play Store) and the development version side-by-side on your phone.

Hope this helps!
