Question

我正在做一个应用，我必须从cdma手机发送短信，但它会抛出空指针异常。我正在使用

smsmanager.sendDataMessage(phonenumber, null, (short)1001, msgStr.getBytes(), sentPI, deliveredPI);

它会抛出如下错误： -

这是函数

        String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent senDPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(SENT),
            0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(
            DELIVERED), 0);

    SmsManager sms = SmsManager.getDefault();

    short s = Short.parseShort(portStr);
    short port = s;

    Log.d("Data", "Sending SMS TO :: "+phonenumber);
    Log.d("Data", "Sending SMS MESSAGE :: "+msgStr);
    Log.d("Data", "Sending SMS on PORT :: "+port);

    sms.sendDataMessage(phonenumber, null, port, msgStr.getBytes(), senDPI, deliveredPI);

所有phonenumber，msgStr，port都来自我的xml布局文件的Edittext字段。我在这里错过了什么？帮助感谢。

send.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            String phoneNo = "Phone number";

从CDMA发送短信（htc evo）会抛出NullPointer异常
