There were several complex problems.

1. GoogleSignin.configure() -> GoogleSignin.configure({WEB_CLIENT_ID}) WEB_CLIENT_ID exist in google-services.json

2. debug keystore setting with use "expo credentials:manager"

• Commend

• This file move to android/app and modify in anroid/app/build.gradle

3. run adb uninstall com.instagram
4. run npx android prebuild & npm run android

if used react native cli, need creating keystore

1. run below command sudo keytool -genkey -v -keystore debug.keystore -alias debug -keyalg RSA -keysize 2048 -validity 10000

2. created keystore move to ./android/app/

3. replace signingConfigs in ./android/app/build.gradle

   • Before

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

• After

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

  4. after run below command, get sha1 value keytool -list -v -keystore ./debug.keystore -alias debug -storepass android -keypass android or ./gradlew signinReport
