# Android build failure

### Android build failure: Special characters in app name

If your app build is failing, your build is stuck, or your download is not completing during the Android build process, the issue may be caused by unsupported special characters in the app name.

Certain special characters can prevent the Android build pipeline from compiling the app successfully.

#### Why this build failure happens

1. Unsupported special characters in the app name
   * Symbols such as emojis or uncommon characters may not be supported
   * The build system may fail to process these characters
2. Encoding or formatting conflicts
   * Special characters can cause compilation errors
   * The Android build process may stop unexpectedly

#### How to fix this Android build failure

1. Review your app name
   * Go to your app dashboard
   * Navigate to the app settings section
   * Check the app name field
2. Remove special characters
   * Remove emojis
   * Remove decorative symbols
   * Keep only standard letters and numbers

{% hint style="warning" %}
Use only standard alphanumeric characters in the app name to avoid Android build failures.
{% endhint %}

3. Save the changes
   * Update the app name
   * Save your settings
4. Rebuild your app
   * Go to the [Download dashboard](https://app.appmysite.com/app/download)
   * Click Rebuild under the Android app card

Once the app name is updated to remove unsupported characters, the Android build should complete successfully.
