自Froyo 2.2起，此代码是否适用于任何设备/ Android版本：
public class SmsObserver extends ContentObserver {

@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
queryLastSentSMS();
}

cur.moveToFirst();
int lastMsgId = cur.getInt(cur.getColumnIndex("_id"));
Log.i(TAG, "Last sent message id: " + String.valueOf(lastMsgId));

我收到一个人的报告，说它不起作用，对我来说，它的工作正常，所以这个：“content：// sms”是否适用于所有Android版本？
