If your app supports Android devices, you should know about recent changes that Google has made. We would like to help you prepare for them. If your app doesn’t support Android devices, you can ignore this message.

1. After November 1, 2018, all app updates that will be delivered via the Google Play app store will need to target API 26 (Android 8.0) or higher. For more information, see Meet Google Play’s target API level requirement.

What does this mean for you?
If you haven’t already done so, please upgrade to the following WCA SDKs that support API 26 (Android 8.0):
Anything at or after Android native SDK
Anything at or after Cordova SDK 3.6.1
Anything at or after Xamarin SDK

2. As of April 10, 2018, Google is deprecating GCM (Google Cloud Messaging). Because of this, it is important that you migrate your Android mobile apps to FCM (Firebase Cloud Messaging).  For more information, see https://developers.google.com/cloud-messaging/.

What does this mean for you?
If you are using a GCM mobile app, you are already using deprecated APIs (as of April 10, 2018). We suspect that soon after April 11, 2019, Google will shut down the GCM server and client APIs.  We strongly recommend that you transition to FCM as soon as possible. This will ensure you have time to make the appropriate changes and give your users time to download your update so they avoid push service interruption.  

We will be withdrawing support for GCM on February 1, 2019.  GCM apps will continue to work until Google shuts down or changes their APIs. Versions of the sample app released after February 1, 2019, will use FCM exclusively, and no testing will be done on GCM.

Check out the step-by-step instructions on how to migrate your mobile app from GCM to FCM: Migrating from Google Cloud Messaging (GCM) to Firebase Cloud Messaging (FCM)

If you are using the following SDKs, FCM is already supported in these versions:
Anything at or after Android native SDK
Anything at or after Cordova SDK 3.5.0
Anything at or after Xamarin SDK
All versions which support API 26 also support FCM.

Thank you for your time and attention.
