Unresolved reference: ReactNativeBlobUtil since 0.21.1

[Relax594]

Using Self-Signed SSL Server doesn't seem to be working anymore after updating to 0.21.1. Been using 0.19.4 before and it was running just fine.

React Native: 0.75.4
React-Native-Blob-Util: 0.21.1

When trying to run Android debug, following errors occur.

Errors:

Unresolved reference: ReactNativeBlobUtil
Unresolved reference: ReactNativeBlobUtilUtils

Reverting to 0.19.4 builds the App just fine again.

@javache are you aware of any problems here with the new extended Baseclass?
Thsat's the only change I can imagine that broke something here.

[javache]

BaseReactPackage was introduced in RN 0.74 and hasn't changed significantly since - you'll want to bump your min version, but that doesn't seem to be the problem here.

[RonRadtke]

Have to try it in a base project then - sounds strange.
is it working normally without th custom trustManager?

[Relax594]

Is it working normally without th custom trustManager?

It successfully builds then, yes.

However, there is a crash on startup with "Cannot read property 'getConstants' of null" here

0.19.11 builds just fine without crash on startup.

[RonRadtke]

I am working on reproducing it and seeing what's wrong

Experiencing the same issue on Expo 52 with React Native 76. Can confirm downgrading works for me too

[RonRadtke]

Seems like the autolinking broke...
But still not sure why exactly

[RonRadtke]

That's the cause of it:
react-native-community/cli#2563

So nothing on my side, but still nasty...

So there are basically 3 solutions:

1. See if you manage to update the cli to the patched version
2. Fix the cli manually by editing the file: @react-native-community\cli-platform-android\build\config\findPackageClassName.js as shown in the linked merge. Basically you just have to adjsut the regex at the end of the file. And afterwards you must clear android/build
3. downgrade this library until a fixed version of RN is available and you can upgrade
4. Downgrade to 0.19.1, build once, copy the section for this lib in android/build/generated/autolinking.json, upgrade, build once, replace the section in the file. From now on it should work.

But tbh. downgrade ist probably the best solution till RN released a fixed version

Thank you for investigating @RonRadtke! Lets wait for RN to fix it.

Thank you for investigating @RonRadtke! Lets wait for RN to fix it.

I am in contact with RN devs there

[RonRadtke]

@Relax594 I just found a work-around to trick autolinking. It's released as a new version

[RonRadtke]

I close the issue since we have a workaround live
