React native integrate to existing android project

Question

i'm trying react native integrate to existing android project but throwed below exception when build project in android studio.

Caused by: java.lang.Exception: React Native CLI failed to determine Android project configuration. This is likely due to misconfiguration. Config output: [root:/Users/muratoner/Desktop/backup/Sabanci.Projects/Mobile/hrweb-react-native/android, reactNativePath:/Users/muratoner/Desktop/backup/Sabanci.Projects/Mobile/hrweb-react-native/node_modules/react-native, dependencies:[:], commands:[], assets:[], platforms:[:], haste:[providesModuleNodeModules:[], platforms:[]], project:[:]] at ReactNativeModules.getReactNativeConfig(/Users/muratoner/Desktop/backup/Sabanci.Projects/Mobile/hrweb-react-native/node_modules/@react-native-community/cli-platform-android/native_modules.gradle:212) at ReactNativeModules$getReactNativeConfig.callCurrent(Unknown Source) at ReactNativeModules.(/Users/muratoner/Desktop/backup/Sabanci.Projects/Mobile/hrweb-react-native/node_modules/@react-native-community/cli-platform-android/native_modules.gradle:84) at native_modules_8dnp0y65ugw2tp4vo89t6lw0x.run(/Users/muratoner/Desktop/backup/Sabanci.Projects/Mobile/hrweb-react -native/node_modules/@react-native-community/cli-platform-android/native_modules.gradle:244) at org.gradle.groovy.scripts.internal.DefaultScriptRunnerFactory$ScriptRunnerImpl.run(DefaultScriptRunnerFactory.java:91)... 148 more

Just add package name in your AndroidManifest.xml

<manifest 
 xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="example"
