How to detect start of Android conversation programmatically?

Question

Android

Good day.
You need to get the status of the call in the Android application, like "Picked up the phone".
When the person on the wire accepts the call and the conversation starts.
CALL_STATE_OFFHOOK helps to understand that the call has started, but something more precise is needed.
I call the call myself programmatically:

Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + number));
        myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(myIntent);

Thanks in advance for your replies.

One option is to read the logs

...
Process logcatProc = Runtime.getRuntime().exec("adb logcat -v time -b radio GSM:D *:S");
BufferedReader mReader = new BufferedReader(new InputStreamReader(logcatProc.getInputStream()), 1024);
