Authentication

  • firebase::auth::GetAuth() now has an option to return a result that indicates whether initialization was successful, and to return nullptr if initialization failed.

Firebase Cloud Messaging

  • firebase::messaging::Initialize() now returns a result that indicates whether initialization was successful.

  • If you call InvitesReceiver::Fetch() or InvitesReceiver::ConvertInvitation() without first calling firebase::invites::Initialize(), the operation will never complete. To work around this issue, ensure that firebase::invites::Initialize() is called once before creating any InvitesReceiver instances.
  • If you create InvitesSender and then InvitesReceiver, the InvitesReceiver may fail to connect, and be unable to fetch results. To work around this issue, you can delay creating the InvitesSender until after the future returned by InvitesReceiver::Fetch() has completed.

Remote Config

  • firebase::remote_config::Initialize() now returns a result that indicates whether initialization was successful.

AdMob

  • firebase::admob::Initialize() now returns a result that indicates whether initialization was successful.

Version 1.0.1 - June 27, 2016

This update includes a variety of documentation updates and minor bug fixes. This update primarily fixes bugs in the AdMob portion of the C++ SDK. These fixes are described below:

  • Modified firebase::App to check for the required version of Google Play services on creation to prevent firebase::App creation from failing if a user's device is out of date. If Google Play services is out of date, a dialog will prompt the user to install a new version. With the previous version of this SDK, you needed needed to manually check for an up-to-date Google Play services SDK using GoogleApiClient.

AdMob

  • Fixed a potential deadlock when using SetListener from a notification callback in firebase::admob::InterstitialAd and firebase::admob::BannerView on iOS.
  • Fixed a race condition on destruction of admob::BannerView on Android.
  • Fixed Future handle leak. An internal memory leak occurred for objects or modules that use futures for the lifetime of the object or module. For example, during the lifetime of a BannerView object, each call to a method which returns a Future could potentially allocate memory which wouldn't be reclaimed until the BannerView object is destroyed.
