android - 发送短信时出现奇怪的错误

Question

我正在尝试使用 Java 代码发送短信。当我发送英文短信时它工作正常。但是当我尝试使用下面给出的俄语消息时失败了。它抛出 NullPointerException。

String message = "Здравствуйтe, сейчас я не могу ответить на Ваш звонок.  Перезвоните через 10 минут, если Вам не ответили. Спасибо";  
PendingIntent pi = PendingIntent.getActivity(this, 0,  
    new Intent(this, RussianSmsProblemActivity.class), 0);                  
SmsManager sms = SmsManager.getDefault();  

sms.sendTextMessage("5556", null, message,sentPI,deliveredPI);//getting Null Pointer Exception here  

代码没有问题，NullpointerException是Android API里面自带的。请高人指点一下这个问题。

这里是异常堆栈跟踪...

Answer 1

我认为这是因为俄语字符在 UTF-8 中消耗 2 字节。所以消息超过了 160 字节限制。尝试改用 sendMultiPartMessage()。
