I am trying to run my react native app in physical device but getting this error. It was running okay but suddenly has stopped working

WORKAROUND

Add this to your android/build.gradle,

def REACT_NATIVE_VERSION = new File(['node', '--print',"JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim())

allprojects {
    configurations.all {
        resolutionStrategy {
            force "com.facebook.react:react-native:"   REACT_NATIVE_VERSION
        }
    }

If that does not work for you (with the dynamic version), then hard code your version in:

PLEASE BE CAREFUL TO MOVE THIS VERSION WHEN YOU UPDATE REACT-NATIVE

allprojects {
    configurations.all {
        resolutionStrategy {
            force 'com.facebook.react:react-native:<your version>'
        }
    }
    repositories {
    // ...
    }
}

            // from a local Maven repo inside node_modules/react-native/.
            // (The use of exclusiveContent prevents looking elsewhere like Maven Central
            // and potentially getting a wrong version.)
            filter {
                includeGroup "com.facebook.react"
            }
            forRepository {
                maven {
                    url "$rootDir/../node_modules/react-native/android"
                }
            }
        }
        // ...
    }
}

This helped me to resolve the issue.

This is happening because all the templates reference the React Native dependency by range, like implementation 'com.facebook.react:react-native: '. Usually this dependency gets resolved from the local Maven repo in ./node_modules/react-native/android but since it has been published to Maven Central it's now grabbing the very latest RC.

You can resolve this problem by forcing the React Native dependency to the version you expect with something like this implementation 'com.facebook.react:react-native:0.68.2!!' in your app's Gradle file. The !! is shorthand for restricting Gradle from upgrading if your project or its transitive dependencies depend on a newer version. AFAIK Maven Central is immutable and the published dependency can't removed so this might be the only solution.


File: android/app/build.gradle
dependencies {
    implementation 'com.facebook.react:react-native:0.67.2!!'
