Voximplant Audio Call Demo with ConnectionService integration

This demo demonstrates audio call of the Voximplant Android SDK with/without ConnectionService integration. The application supports audio calls between the current Android app and other apps that use any Voximplant SDK. It uses two ways to control calls:

• Default (AudioCallManagerDefault)
• Integration with self-managed ConnectionService (AudioCallManagerTelecom)

The choice of implementation depends on the device's Android version and the FEATURE_TELECOM or FEATURE_CONNECTION_SERVICE availability in the system.

ConnectionService is an abstract service that could be implemented by any apps which either:

1. Can make phone calls (VoIP or otherwise) and want those calls to be integrated into the built-in phone app. Referred to as a system managed ConnectionService.
2. Are a standalone calling app and don't want their calls to be integrated into the built-in phone app. Referred to as a self-managed ConnectionService. ConnectionService requires Android API level 23 according to the official Android documentation, but this app uses Connection.PROPERTY_SELF_MANAGED which requires API level 26.

Features

The application is able to:

• log in to the Voximplant Cloud
• make an audio call
• receive an incoming call
• put a call on hold / take it off hold
• change an audio device (speaker, receiver, wired headset, bluetooth headset) during a call
• mute audio during a call
• receive push notifications (requires additional setup)
• proximity sensor usage
