Whenever I run react-native run-android while keeping the emulator running, I get this error. react-native run-ios wroks completely fine.
Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081 :ReactNative:Failed to parse React Native CLI configuration: groovy.json.JsonException: Unable to determine the current character, it is not a string, number, array, or object The current character read is 'E' with an int value of 69 Unable to determine the current character, it is not a string, number, array, or object line number 1 index number 0 Error: Invalid attribute nameLine: 16Column: 18Char: . at error (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:651:10) at strictFail (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:677:7) at SAXParser.write (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:1313:13) at new XmlDocument (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/xmldoc/lib/xmldoc.js:261:15) at readManifest (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/build/config/readManifest.js:38:10) at Object.projectConfig (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/build/config/index.js:59:46) at Object.get project [as project] (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/tools/config/index.js:114:50) at /Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/commands/config/config.js:8:452 at Array.forEach (<anonymous>) at _objectSpread (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/commands/config/config.js:8:392) ^ FAILURE: Build failed with an exception. * Where: Script '/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/native_modules.gradle' line: 201 * What went wrong: A problem occurred evaluating script. > Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/yashatreya/Desktop/Realyze/Realyze' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again * Try: Run with --stacktrace option to get the stack trace.

As indicated in the error message, I tried running npm uninstall -g react-native react-native-cli but it didn’t work.

Initially I was getting this error: react-native build error: Could not find method implementation() for arguments [jscFlavor] on project ‘:app’ of type org.gradle.api.Project but now I am getting the above.

Answer
SOLUTION 1 (worked for me)
The solution for me was removing the following line
apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)
Be sure to remove it everywhere. I had this line in build.gradle (app) and also in settings.gradle.
After that, run again npx react-native run-android the console will display the real error, fix the error and put back the lines you had removed.
In my case the error happened because I have been using an older Node version and the second time It happened I needed to sync my project again
SOLUTION 2
Delete the files it was finding error as “The current character read is ‘E’ with an int value of 69”
Deleting
appbuildintermediatessigning_configdebugoutsigning-config.json
worked for others too.
SOLUTION 3
Update the @react-native-community/cli to the latest version.
Good coding!
