We are developing a healthcare app. We need to add a video Calling feature between doctor and patient.
Target: API 21 and above
Recording of all video calls (locally on doctor's mobile or amazon s3)
Kotlin language if possible
To reduce work and our cost, some video call apis like sinch, tokbox, or agora can be used.
You can use any server to generate sessions and tokens
You can use FCM for notification part
