Writing a GSM emulator for use with Android -

Writing a GSM emulator for use with Android -

Whatever I am doing, I have to keep an emulated GSM modem which is a VM on an Android-x86 virtual machine Unix socket Should look at the emulator as a real modem and use it to send the SMS (as the first pass of functionality).

So far, I've put something which handles AT commands and only "OK" for some commands to rest, such as "AT + CRSM", run official Android emulator and Looking at the radio log I have only one response, for others, I maintain some states and prepare the answers; Those commands include:

  CPU? CPIN? CGREG? CGREG? police? CGRG = CRG = CPIN = Cops = CRSM = CSMS = CGSN CIMI CSK    Android will boot and send the command to my emulate modem, which responds, although it does not appear completely Is functional For example, Android does not detect the strength of any radio signal, just showing "x" in the signal bar.  
 Does anyone detect a similar project, or what the AT commands are  Absolutely  is required to achieve some basic functionality?   
 
  Well, I will answer my other questions, this is an easy way.  
 I have implemented an emulator which maintains a bit of state, such as unwanted CREG and CGREG messages are enabled, network registration status & amp; Network Name Format (for COOP command), and a message reference counter for SMS  
 It supports the following commands:  
  CFUN? CPIN? CGREG? CREG? police? CGRG = CRG = CPIN = Cops = CRSM = CSMS = CMGS = CGNS CIMI CSAQ    All other messages get just one "OK" response.  
 The stock is running in an emulator with AOP Android source "Erico Unix: / TMP / Phone" switch, I can send an SMS message and decode binary PDU in real messages. I will continue to add functionality so that SMS messages can be injected back to Android and hopefully the code will be open at some point.

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.

android - How to build apk without eclipse or Modify the apk building
with a config file? -



    I want to create an APK with some big configurations with an XML file.  I want to know if there is any method which can control the APK's building process or encoding at our source, there is no way to create APK with our source from our source, with a slight variation based on our SQF XML file. . Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code. Eclipse automatically produces an .apk file in the project's bin folder, so you do not need to do anything extra to generate .apk.   If you are developing in a non-eclipse environment, then you create your project with the Generated Build.xml Ant file in the project directory that creates ant file calls which automatically targets you for Call the buil...
