Question

我的移动电话有时是发送文字信息,但大多数电话都非常有用,但我开始接收一些用户的电子邮件,称这些电文是线索。这里使用的是:

SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage("+12223334444", null, "test sms", null, null);

I ve read somewhere that I should use the PendingIntent, so i tried it as follows:

PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, new Intent("SMS_SENT"), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0, new Intent("SMS_DELIVERED"), 0);                     
SmsManager sm = SmsManager.getDefault();
sm.sendTextMessage(number, null, message, sentPI, deliveredPI);

So far I have gotten emails from users of Samsung Galaxy S II, Sprint Evo Shift, Samsung Sidekick phones.

The problem here is that you aren t handling retries at all. It is possible for the SMS to fail to send in a variety of colourful ways. You can listen for these events using the sent PendingIntent using something like:

public void onReceive(Context context, Intent intent) {
    if (getResultCode() != Activity.RESULT_OK) {
        // failed to send the sms, see SmsManager.ERROR_<description> for more info on why
    }
}

我怀疑正在发生的是,用户在发出电文时没有信号,因此它失败,从未尝试过。这也将解释为什么它带有特定标记。
