Initialize the Voxeet SDK

Two methods are currently available to initialize the SDK:

• Set the API keys in the app
• Use an OAuth2 server to provide the keys

initialize with keys

Initialize the SDK with your Voxeet user information.

Parameters

• context ApplicationContext - A NonNull ApplicationContext.
• consumerKey string - The consumer key for your app from your developer account dashboard.
• consumerSecret string - The consumer secret for your app from your developer account dashboard.

• userInfo object - A Nullable UserInfo object that contains custom user information.

  • userInfo.name string - The user name.
  • userInfo.externalId string - An external ID for the user.
  • userInfo.avatarUrl string - An avatar URL for the user.

Example

UserInfo externalInfo = new UserInfo(externalName, externalName, externalPhotoUrl);

VoxeetSdk.sdkInitialize(context, consumerKey, consumerSecret, externalInfo);

initialize with OAuth2

Initialize the SDK with a valid token and a method to refresh it.

Parameters

• context ApplicationContext - A NonNull ApplicationContext.
• tokenAccess string - A valid tokenAccess obtained from your own Oauth2 server.
• consumerSecret callable - A callback which will return a valid tokenAccess when called from the SDK.

• userInfo object - A Nullable UserInfo object that contains custom user information.

  • userInfo.name string - The user name.
  • userInfo.externalId string - An external ID for the user.
  • userInfo.avatarUrl string - An avatar URL for the user.

Example

UserInfo externalInfo = new UserInfo(externalName, externalName, externalPhotoUrl);

Callable<String> tokenRefresh = new Callable<String>() {
    @Override
    public String call() throws Exception {
        //retrofitService is a valid proxy object from a Retrofit interface
        return retrofitService.toBlocking().single();
    }
};

VoxeetSdk.sdkInitialize(context, tokenAccess, tokenRefresh, externalInfo);

register
