Adding video calls to messaging

How to add video call capabilities to the messaging components

Video call SDK dependency

To add video calls capability to the messaging module, add the following line to your build.gradle:

implementation 'com.nabla.nabla-android:video-call:1.0.0-alpha20'

Set up video call module

The next step is to set up the NablaVideoCallModule when you init the NablaClient:

class MyApp : Application() {
    override fun onCreate() {

            modules = listOf(
                NablaVideoCallModule(), // Add this line

Build and run your app, you should now be able to receive video call CTAs in a conversation and answer them.

Your first video call

From the Nabla Console, a provider can now send a video call CTA that the patient can tap to join the call.

The patient will have to accept the Microphone and Camera permissions and will then be able to join the call.


You can override Video call specific attributes by providing your own Nabla.ThemeOverlay.VideoCall. Here's how it works:

<style name="Theme.Example.Blue" parent="Theme.Material3.Light.NoActionBar">
    <!-- Rest of your theme -->

    <item name="nablaVideoCallThemeOverlay">@style/NablaOverlay.Example.VideoCall</item>

<style name="NablaOverlay.Example.VideoCall" parent="Nabla.ThemeOverlay.VideoCall">
    <item name="nablaVideoCall_micIcon">@drawable/customMicIcon</item>
