用于检测Sip会话的广播接收器

public class MySipBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理接收到的广播消息
        if (intent.getAction().equals("android.sip.action.CALL_STATE_CHANGED")) {
            // 处理SIP呼叫状态变化
            int callState = intent.getIntExtra("android.sip.extra.CALL_STATE", -1);
            switch (callState) {
                case SipManager.CALL_STATE_RINGING:
                    // 处理来电
                    break;
                case SipManager.CALL_STATE_OFFHOOK:
                    // 处理接通电话
                    break;
                case SipManager.CALL_STATE_IDLE:
                    // 处理挂断电话
                    break;
                default:
                    // 其他状态
                    break;
            }
        }
    }
}
