VoIP calls on Android

เนื้อหานี้ยังไม่มีในภาษาของคุณ

Pushwoosh supports VoIP-style call notifications for Android using the pushwoosh-calls module. This enables native call UI and lifecycle management using Android’s telecom stack.

1. Add the `pushwoosh-calls` module

Make sure to include the pushwoosh-calls dependency in your project.

Gradle:

dependencies {
    implementation 'com.pushwoosh:pushwoosh-calls:<latest-version>'
}

Replace <latest-version> with the current version from Maven Central.

2. Request call permissions

Request required permissions at runtime using the helper function:

import com.pushwoosh.calls.PushwooshCallSettings;

PushwooshCallSettings.requestCallPermissions();

This handles requesting permissions like READ_PHONE_NUMBERS, necessary for proper call handling.

3. Implement `CallEventListener` and register it in the Manifest

To handle incoming calls and events, implement the CallEventListener interface in your app.

Java example

public class DemoCallEventListener implements CallEventListener {

    @Override
    public void onAnswer(@NonNull PushwooshVoIPMessage voIPMessage, int videoState) {
        // implement this method to navigate to your in-call UI
        Intent intent = new Intent(context, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);
    }

    @Override
    public void onReject(@NonNull PushwooshVoIPMessage voIPMessage) {
        // override this method to handle dismissed calls
    }

    @Override
    public void onDisconnect(@NonNull PushwooshVoIPMessage voIPMessage) {
        // override this method to handle disconnected calls
    }

    @Override
    public void onCreateIncomingConnection(@Nullable Bundle payload) {
        // this is the earliest point when call notification payload is accessible in your app,
        // use it to prepare your app UI for user interactions with call notifications
    }

    @Override
    public void onCallAdded(@NonNull PushwooshVoIPMessage voIPMessage) {
        // extension method of InCallService, provides customization options for paired Wearable devices
    }

    @Override
    public void onCallRemoved(@NonNull PushwooshVoIPMessage voIPMessage) {
        // extension method of InCallService, provides customization options for paired Wearable devices
    }
}

AndroidManifest.xml

Declare your listener class using a <meta-data> tag:

<meta-data
    android:name="com.pushwoosh.CALL_EVENT_LISTENER"
    android:value="com.pushwoosh.demoapp.DemoCallEventListener" />

4. Configure call settings (optional)

Use PushwooshCallSettings to fine-tune call behavior, sounds, and display settings.

Example usage

import com.pushwoosh.calls.PushwooshCallSettings

PushwooshCallSettings.setPhoneAccount("com.pushwoosh.voip")
PushwooshCallSettings.setPhoneAccountHandle("PushwooshCallHandle")
PushwooshCallSettings.setIncomingCallChannelName("Incoming Calls")
PushwooshCallSettings.setOngoingCallChannelName("Ongoing Calls")
PushwooshCallSettings.setCallSound("custom_ringtone.mp3")
