Migrating from 3.x to 4.x - Android

This guide provides an introduction to the 4.x Programmable Video Android SDK and a set of guidelines to migrate an application from 3.x to 4.x.

Programming Model

The programming model has not changed from 3.x to 4.x. Refer to our 2.x migration guide for a refresher on the Video Android SDK models.

WebRTC

The media stack, WebRTC 67, has not changed from 3.x to 4.x. The process by which our team upgrades WebRTC has been improved and developers can expect a steadier cadence of releases with WebRTC upgrades moving forward.

Java 8

The Video Android SDK has not changed JDK versions from 3.x to 4.x. Consumers of the Video Android SDK must update their applications to use Java 8 if they haven't done so already. Add the following to your application build.gradle to enable Java 8 features.

android {
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
}

Optionally, you can also instruct Android Studio to optimize your project for Java 8 by clicking "Analyze -> Inspect Code".

Reconnecting API

In 4.x we have introduced a new set of callbacks in Room.Listener to notify developers of a network disruption. As a result, developers will need to add these new callbacks to every instance of the Room.Listener interface.

@Override
public void onReconnecting(@NonNull Room room, @NonNull TwilioException twilioException) {

}

@Override
public void onReconnected(@NonNull Room room) {

}
