我创建的应用程序如果单击该按钮，它将向来自webservice的号码发送SMS。然后我使用警报管理器以我从Web服务获得的号码重复发送SMS。它工作正常，但当我更改我要发送短信的号码时，它将无法正常工作。我不知道我的代码有什么问题。这是我的代码。
这是我发送短信的代码。

//Toast.makeText(context, num + msg, Toast.LENGTH_SHORT).show();
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(num, null, msg, null, null);
}
}
这是我的清单，允许发送短信和注册闹钟接收器。
