# Play Console: You uploaded an APK or Android App Bundle that was signed in debug mode. You need to sign your APK or Android App Bundle in release mode

**Code:** `signed in debug mode` · **Category:** Android · **Seen on:** Android

The bundle was signed with the debug keystore; Play only accepts release-signed uploads.

## Meaning

Building the release variant without a release signingConfig (or Flutter/RN defaults that reuse debug signing) produces a debug-signed artifact.

## Common causes

- release buildType uses signingConfigs.debug
- Uploading the debug build output
- Flutter/React Native template default signing

## Quick fix

1. Create an upload keystore and a release signingConfig
2. Build bundleRelease and upload app-release.aab
3. Use Play App Signing with your upload key

## Detailed fix by platform

### Gradle

1. 

```kotlin
android {
  signingConfigs { create("release") { storeFile = file("upload.jks"); storePassword = System.getenv("KS_PASS"); keyAlias = "upload"; keyPassword = System.getenv("KEY_PASS") } }
  buildTypes { release { signingConfig = signingConfigs.getByName("release") } }
}
```


## How to diagnose

1. **Signer** — keytool -printcert -jarfile app-release.aab
2. **Build** — Which variant was uploaded?
