Android app: Namespace not specified. Please specify a namespace in the module's build.gradle file like so:

[aihoque2]

updating my react-native app from 0.69.5 to 0.72.1. However, when I try to build with npx react-native run-android or do a ./gradlew clean I get this bug:

A problem occurred configuring project ':@react-native-community_blur'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Please specify a namespace in the module's build.gradle file like so:
     
     android {
         namespace 'com.example.namespace'
     }

here's my android/app/build.gradle:

apply plugin: "com.android.application"
apply plugin: "com.facebook.react"
import com.android.build.OutputFile


project.ext.react = [
    entryFile: "index.js",

How do specify the namespace in my android/app/build.gradle?

[thommedia]

Any update on this? I have the same issue.

[SERCHAT]

I have already this issue please help!

[L0rdCr1s]

@SERCHAT just go to the library build.gradle and add namespace 'your_namespace' and the error will go away.

[SERCHAT]

Thank you @L0rdCr1s. Because I use a lot of packages which are not using namespace in theirs build.gradle files I 'am looking for a gradle script who do this job. For this library only your recommendation worked perfectly thank you again.
