How to identify a call is disconnected when there are multiple calls in Android

Question

My problem is when i have multiple received calls (say 3 of 2 hold and 1 active), i don't get CALL_STATE_IDLE when the caller disconnect for any of the 2 calls. But get CALL_STATE_IDLE when last call is disconnected. CALL_STATE_RINGING & CALL_STATE_OFFHOOK works fine.

public void onCallStateChanged(int state, String incomingNumber) {
 super.onCallStateChanged(state, incomingNumber);
 Log.e("MyService", "Switch " + state);
switch (state) {

case TelephonyManager.CALL_STATE_OFFHOOK:
    Log.e("MyService", "CALL_STATE_OFFHOOK");
    break;

case TelephonyManager.CALL_STATE_RINGING:
    Log.e("MyService", "CALL_STATE_RINGING");
    break;

case TelephonyManager.CALL_STATE_IDLE:
    Log.e("MyService", "CALL_STATE_IDLE");
    break;

default:
    Log.e("MyService", "default");
    break;
}
}

This is not an answer to solve your problem. But, it definitely adds value to the solution

What is CALL_STATE_IDLE ?

Device call state: No activity.

So, we shouldn't expect it to send CALL_STATE_IDLE state when there is an active line. That's why the event CALL_STATE_IDLE is broadcasted only when all the calls are disconnected
