Your Android App Bundle is signed with the wrong key. Ensure that your app bundle is signed with the correct signing key and try again

I tried using the multiple answers here & in this question, but somehow I was getting this error because I had some issues with my android/app/build.gradle and android/gradle.properties files.

Two things you should check (in addition to the other solutions here) are:

1. In android/gradle.properties and android/app/build.gradle, make sure your keystore variables match exactly.
   • In android/gradle.properties, you probably have something like this:

     MYAPP_RELEASE_STORE_FILE=<>
     MYAPP_RELEASE_KEY_ALIAS=<>
     MYAPP_RELEASE_STORE_PASSWORD=<>
     MYAPP_RELEASE_KEY_PASSWORD=<>
     

   • Make sure these variable names exactly match those in android/app/build.gradle:

     android {
         ...
         signingConfigs {
             release {
                 if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                     storeFile file(MYAPP_RELEASE_STORE_FILE)
                     storePassword MYAPP_RELEASE_STORE_PASSWORD
                     keyAlias MYAPP_RELEASE_KEY_ALIAS
                     keyPassword MYAPP_RELEASE_KEY_PASSWORD
                 }
             }
         }
     }
     

2. In android/app/build.gradle, make sure you set signingConfig to signingConfigs.release in your release buildTypes:

   android {
       ...
       buildTypes {
           debug ...
           release {
               signingConfig signingConfigs.release
           }
       }
   }
