本文介绍了Android的:问题与发送短信的数据的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我已经写了code发送加密邮件。
但是,加密的数据短信不提供,因为onrecive()梅索德不调用。我想我已经在接收器部分的问题。

现在,我在Android的新..任何身体帮我什么是错用下面的code(我使用RSA算法中)?在此先感谢........

解决方案

您只需要注册一次您的接收器。
注册您在有接收器SMSbomb(PHONENO,消息); 的onCreate()来代替。
我希望帮助!

I have written code to send encrypted message.But the encrypted data SMS is not delivering because onrecive() methode is not invoking . I think I have problem in receiver part.

Now, I am new in android.. Any body help me what is the wrong with the following code (I am using RSA algo)? Thanks in advance........

For Sending:

public class MainMethod extends Activity 
{
    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

        btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
        txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
        txtMessage = (EditText) findViewById(R.id.txtMessage);

解决方案

You only need to register your receiver once. Register the receivers that you have in SMSbomb(phoneNo,message ); in onCreate() instead.I hope that helps!
