For the Javascript version of cocos2d-x v3.x - (all other versions)

Prerequisites

Currently, Amazon is only available for Android. Register as a Amazon Develper follow https://developer.amazon.com/.
Amazon Kindle Fire device

NOTE:

If you are using Amazon plugin then you must install IAP plugin at first to make it to work.

SDK Version

android: in-app-purchasing-2.0.76.jar

Integration

Open a terminal and use the following command to install the SDKBOX Amazon plugin. Make sure you setup the SDKBOX installer correctly.

$ sdkbox import amazon
$ sdkbox set store amazon

Extra steps

The following step assumes you have already registered as a Amazon Developer in the Amazon Developer Portal and created a new game there.

Setup Android

Open AndroidManifest.xml add the following line:

<meta-data android:name="store" android:value="amazon" />

NOTE: If you submit your apk to other store, such as Google Play, please remove this line or set the store with googleplay, otherwise, you will get wrong configuration for the other store. Example: <meta-data android:name="store" android:value="googleplay" />

$ sdkbox set store googleplay

JSON Configuration

SDKBOX Installer will automatically inject a sample configuration to your sdkbox_config.json, that you have to modify it before you can use it for your own app

Here is an example adding Amazon:

{
    "ios":
    {
    },
    "android":
    {
    },
    "amazon" :
    {
        "iap":
        {
            "items":{
                "remove_ads":{
                    "id":"com.cocos2dx.non1",
                    "type":"non_consumable"
                },
                "double_coin":{
                    "id":"com.cocos2dx.non2",
                    "type":"non_consumable"
                },
                "coin_package":{
                    "id":"com.cocos2dx.plugintest2"
                },
                "coin_package2":{
                    "id":"com.cocos2dx.plugintest3"
                }
            }
        }
    }
}

proguard.cfg
