Can you please share:

1. your android/app/build.gradle file?
2. the full build log

Plus having a repro would help

Please share the missing things I asked. Plus the file I asked for is android/app/build.gradle and not android/build.gradle.

[priyaWedo]

@cortinico updated the file , please review it

[cortinico]

The issue is caused by one of your dependency. Sadly it's impossible to say which one, as I see you have :react-native-twilio-video-webrtc and :react-native-maps

I suspect the issue will be fixed once you bump the version of those dependencies:

• RN-0.73 change Android configs for RN 0.73 compatibility blackuy/react-native-twilio-video-webrtc#713

Closing for now as this is not an issue in React Native itself

@cortinico thank you for your help

Hi, I managed to solve this error by including the namespace in the dependencies that caused the errors. I located them from my node modules, navigated to the build.gradle file of each dependency in the android directory, and then added the namespace under the android block.

### Below is the exact solution I applied to this error for the react-native-splash-screen dependency.

def safeExtGet(prop, fallback) {
rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}

apply plugin: 'com.android.library'

def DEFAULT_COMPILE_SDK_VERSION = 26
def DEFAULT_BUILD_TOOLS_VERSION = "26.0.2"
def DEFAULT_TARGET_SDK_VERSION = 26
def DEFAULT_SUPPORT_LIB_VERSION = "26.1.0"

android {
namespace "com.example.app" // <- add this here
compileSdkVersion rootProject.hasProperty('compileSdkVersion') ? rootProject.compileSdkVersion : DEFAULT_COMPILE_SDK_VERSION
buildToolsVersion rootProject.hasProperty('buildToolsVersion') ? rootProject.buildToolsVersion : DEFAULT_BUILD_TOOLS_VERSION

defaultConfig {
    minSdkVersion safeExtGet('minSdkVersion', 16)
    targetSdkVersion rootProject.hasProperty('targetSdkVersion') ? rootProject.targetSdkVersion : DEFAULT_TARGET_SDK_VERSION
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {
def supportLibVersion = rootProject.hasProperty('supportLibVersion') ? rootProject.supportLibVersion : DEFAULT_SUPPORT_LIB_VERSION

implementation fileTree(dir: 'libs', include: ['*.jar'])
testImplementation 'junit:junit:4.12'
implementation "com.android.support:appcompat-v7:$supportLibVersion"
implementation "com.facebook.react:react-native:+" // From node_modules

}

I hope this helps someone solve this problem. If it does, that will be awesome.

The presentation above depicts a rookie's mistake, but I want to direct your attention to the lines below,

android {
namespace "com.example.app"
compileSdkVersion rootProject.hasProperty('compileSdkVersion') ? rootProject.compileSdkVersion : DEFAULT_COMPILE_SDK_VERSION
buildToolsVersion rootProject.hasProperty('buildToolsVersion') ? rootProject.buildToolsVersion : DEFAULT_BUILD_TOOLS_VERSION

defaultConfig {
    minSdkVersion safeExtGet('minSdkVersion', 16)
    targetSdkVersion rootProject.hasProperty('targetSdkVersion') ? rootProject.targetSdkVersion : DEFAULT_TARGET_SDK_VERSION
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

[MechLocator]

Make sure to replace "com.example.app" with the package name from each dependency's AndroidManifest.xml file which you should find in the "../android/src/main/AndroidManifest.xml" path.

For example, if the package name from AndroidManifest.xml is "com.sortnumbers.mathsapp", then in the dependency's build.gradle file, inside the android scope, make sure you've indicated this exactly.

android {
namespace "com.sortnumbers.mathsapp"
}

@cortinico By any chance is there any workaround for this issue if third-party dependencies are not having that namespace defined in their respective build gradle files?

For react native 0.73+ AGP 8+ is required and that enforces all the libraries to have namespace: react-native-community/discussions-and-proposals#671

Currently, upgrading to 0.73+ is a bit challenging because that namespace required build error is expected. Not only in this single third-party library, but build throws an error in other libraries as well.

For e.g

Manually adding namespace in gradle file of each dependencies resolves this issue, somehow this can be a patch package for few depdencies until there's an update available, but that's not feasible when application has multiple dependencies

Even following workaround is also not working. Any workaround is highly appreciated on this issue. Thank you!

android/build.gradle
--------------------

allprojects {
  ....
}

subprojects {
      afterEvaluate {
          project ->
              if (project.hasProperty("android")) {
                  android {
                      def agpVersion = com.android.Version.ANDROID_GRADLE_PLUGIN_VERSION.tokenize('.')[0].toInteger()
                      if (namespace == null && agpVersion >= 7) {
                          namespace project.group
                      }
                  }
              }
      }
  }

Why is it not feasible with multiple dependencies?
You should reach out to those dependencies and ask them to update their libraries to conditionally add namespace in their Gradle files.

Other than this, there is nothing much we can do. We communicated this change long ago exactly to avoid scenarios like this. If you're depending on old/unmaintained libraries, I would advice to consider moving away from those dependencies.
