This application provides a sample demonstrating phone calls detection. Upon deploying this sample application, you should be able to have two-way audio and video communication using OpenTok. Audio and video streams published from device to OpenTok session will be halted for the duration of ongoing phone call.
Main features:
- Create 2-way OpenTok video call
- Detect incoming and outgoing native phone calls
- Disable device video/video while being onCallStateChanged the phone call
Open the OpenTokConfig file and configure the API_KEY, SESSION_ID, and TOKEN variables. You can obtain these values from your TokBox account.
This is the code responsible for listening for the call status:
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
//Phone state permissions are required from Api 31. Add check of permission to avoid crash.
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
//...
private PhoneStateListener phoneStateListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE: //Initial state
Log.d("onCallStateChanged", "CALL_STATE_IDLE");
break;
case TelephonyManager.CALL_STATE_RINGING: // Incoming call Ringing
Log.d("onCallStateChanged", "CALL_STATE_RINGING");
break;
case TelephonyManager.CALL_STATE_OFFHOOK: // Outgoing Call | Accepted incoming call
Log.d("onCallStateChanged", "CALL_STATE_OFFHOOK");
break;
default:
Log.d("onCallStateChanged", "Unknown Phone State !");
break;
}
}
