# Custom binary names

> How to change produced binary names for Android and iOS

## iOS

In order to change the file name for the generated **.ipa** artifact, edit the **CFBundleDisplayName** key in the `Info.plist` file.

If the app is configured with **flavors**, the **CFBundleName** key needs to be configured with a custom name.


## Android

In order to change the artifact file name for Android apps, edit the **archiveBaseName** property in the `app/build.gradle` file.

For example, to generate a binary name using your app package name and version:


```Groovy

defaultConfig {
   setProperty("archivesBaseName", applicationId + "-v" + versionCode + "(" + versionName + ")")
  }

```


To use some arbitrary custom name, set the property as follows:


```Groovy

  setProperty("archivesBaseName", "YOUR_CUSTOM_NAME")

```


#### Flutter

As Flutter does not allow binary names to be changed in `build.gradle`, a temporary workaround is to use the `mv` command. Make sure to reference the new .apk file in the `artifacts` section:


```yaml

  scripts:
    - name: Rename the apk and aab file
      script: | 
        mv build/app/outputs/flutter-apk/app-release.apk \
          build/app/outputs/flutter-apk/my_renamed_binary_name-release.apk

        mv build/app/outputs/bundle/release/app-release.aab \
          build/app/outputs/bundle/release/my_renamed_binary_name-release.aab
  artifacts:
    - build/app/outputs/flutter-apk/my_renamed_binary_name-release.apk
    - build/app/outputs/bundle/release/my_renamed_binary_name-release.aab

```
