   base64 release.keystore > release.keystore.base64

   Copy the contents and add it as a GitHub Secret (ANDROID_KEYSTORE_BASE64).

2. Google Play Service Account: Create a service account in your Google Cloud Console, give it permissions in Google Play Console, download the JSON key, and add the entire JSON file contents as a GitHub Secret (PLAY_CONSOLE_JSON).

3. Other Secrets: Make sure to add ANDROID_KEYSTORE_PASSWORD, ANDROID_KEY_ALIAS, and ANDROID_KEY_PASSWORD as GitHub Secrets.
