Amazon requires a PEM file that contains a unique app-specific public key to establish a secure communication channel between the Amazon Appstore and your app.

To get the PEM file, please reach out to us at dev-support@now.gg.
Include the PEM file based on the following instructions:
Native Android:
- Paste the PEM file into the app/src/main/assets directory of your Android Studio project.
  Note: If your app doesn’t have an assets directory, you must create one and place the PEM file into it.
Unity:
- In the Assets folder of your project, create a new folder named StreamingAssets.
  - Paste the PEM file in Assets/StreamingAssets.

1.2 Huawei AppGallery

Huawei requires a custom launcher manifest in your app build.
