[Android] ReactNative-application.cmake build failed when in the library project.

[jsonhu]

Description

when I create CMakeLists.txt in the library project, and the content of the CMakeLists.txt as follows:

cmake_minimum_required(VERSION 3.18.1)

# Define the library name here.
project(appmodules)
# This file includes all the necessary to let you build your application with the New Architecture.
include(${REACT_ANDROID_DIR}/cmake-utils/ReactNative-application.cmake)

target_link_libraries(${CMAKE_PROJECT_NAME})

after that I executed gradle sync and the build failed with the following result:

Could not find a package configuration file provided by "ReactAndroid" with any of the following names:

ReactAndroidConfig.cmake
reactandroid-config.cmake

Add the installation prefix of "ReactAndroid" to CMAKE_PREFIX_PATH or set "ReactAndroid_DIR" to a directory containing one of the above files. If "ReactAndroid" provides a separate development package or SDK, be sure it has been installed.

Version

0.71.1

Steps to reproduce

1. create android library module
2. create jni/CMakeLists.txt under the main folder
3. copy from react-native/ReactAndroid/cmake-utils/default-app-setup/CMakeList.txt into your library jni/CMakeList.txt
4. config externalNativeBuild in library build.gradle
5. gradle sync

Is it necessary to provide a "ReactNative-library.cmake" in cmake-utils?

@jsonhu did you happen to find out what the solution is here? I seem to have the same problem.

[basbase]

Not sure if this is the same issue, but it may give a hint: When I encountered an error about CMakeList.txt after upgrading to RN 0.71, it turned out I had a dependency that was using an ancient version of react-native-gradle-plugin. When I then added the latest version of react-native-gradle-plugin to the devDependencies of my project the build could succeed.

config prefab=true in library build gradle just solve my problem

@jsonhu where should prefab=true be set? I'm facing the same issue

@jsonhu > I just ran into the same issue.

I assume you are setting up a New Architecture RN app, e.g. by following: https://reactnative.dev/docs/next/the-new-architecture/cxx-cxxturbomodules

You must set

# Use this property to enable support to the new architecture.
# This will allow you to use TurboModules and the Fabric render in
# your application. You should enable this flag either if you want
# to write custom TurboModules/Fabric components OR use libraries that
# are providing them.
newArchEnabled=true

in {pathToYourAwesomeProject}/android/gradle.properties

It is false by default

I had the same issue only if I do not enable the new architecture. I was also able to reproduce the problem on the sample app with react native 0.73.1.

Issue was resolved as @jsonhu suggested. Added prefab=true under buildFeatures config block.

    buildFeatures {
        prefab=true // add this
    }

    externalNativeBuild {
        cmake {
            path "$projectDir/src/main/jni/CMakeLists.txt"
        }
    }

    signingConfigs {
        debug {
            storeFile file('debug.keystore')
            storePassword 'android'
            keyAlias 'androiddebugkey'
            keyPassword 'android'
        }
    }
