我们如何在Android中模拟通话和短信？

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telephonyManager != null) {
    GsmCellLocation cellLocation = (GsmCellLocation) telephonyManager.getCellLocation();
    if (cellLocation != null) {
        int cid = cellLocation.getCid();
        int lac = cellLocation.getLac();
        Log.d("TAG", "CID: " + cid + ", LAC: " + lac);
    }
}

SmsManager smsManager = SmsManager.getDefault();
String phoneNumber = "1234567890";
String message = "Hello, this is a test message!";
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
