Subscriptions Not Triggering Sometimes Even Though There Is Stable Internet

[manum176]

We are using the SDK for an android project. When the mutations are triggered from backend (Lambdas, APIs, etc.) the subscriptions are not getting invoked sometimes even though the internet connection is stable. After 3-4 retries, it will get invoked

Expected behaviour
The subscriptions should trigger in any case if there is a stable internet connection

Environment:

• AppSync SDK Version: 2.6.26

Device Information:

• Device: Samsung J8, Redmi Note 5 Pro
• Android Version: Marshmallow 6.0, Oreo 8.1

Thanks in advance

Sorry to hear that you are running into issues. One of the areas to look into is to check if your subscriptions are active and not disconnected. Can you post logs from your logcat ( at the verbose setting) and I can look through to see if there are any connection drops. Also, can you share a code snippet from your app - specifically the subscription and the callback logic?

The latest version of the SDK 2.6.27 contains a fix to set to the QoS to 1, which will give you at least once message delivery. Please try this out and let us know how you fare.

Since the realtime updates were much critical for our project, we could not continue with AppSync. So we moved to some alternate solutions and hold AppSync for the time being.

However, we will check this and let you know.
