android - sendTextMessage 在安卓手机中

Question

这是发送短信的简单代码。

47: SmsManager sms = SmsManager.getDefault();
48: sms.sendTextMessage("12345678901", null, "hello!", null, null);

但是我无法运行这段代码。这段代码在android 2.1版本运行成功，但是我的手机，Samsung galaxy II，却出现了NullPointException错误。告诉我那个问题。这是 AndroidManifest.xml 代码和错误日志。

<uses-permission android:name="android.permission.SEND_SMS"/>

如下所示在第 48 行给出未决 Intent

String sent = "android.telephony.SmsManager.STATUS_ON_ICC_SENT";
PendingIntent piSent = PendingIntent.getBroadcast(smsActivity.this, 0,new Intent(sent), 0);

sms.sendTextMessage("12345678901", null, "hello!", piSent, null);

我确定它有效:)
