Android Listen to Network State Change

This will help you to detect network changing states in android phone. For get an idea abut the API use for this read Followings.

• PhoneStateListner
• ServiceState
• TelephonyManager

Following Steps will do it. After setup the code and run the app just change your network status to flight mode and then again revert.

First we need to add required permission to read the changes of network connectivity. Insert following line in you AndroidManifest.xml file to do that.

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

CodeBlocks Installing and Troubleshooting in UBUNTU

             sudo apt-get install codeblocks

Tips for JS

Seacrh a value exists in string or array  (indexOf()
 
var str = "Hello world";
var n = str.indexOf("world")

This will return 2 for n. (Position of search key "world").
For not existing values this function will return -1.  ;)

* When delete an item in array always use splice instead of delete. Coz delete will replace the deleted item from undefined but splice not.

============================================================================
Disable Backspace and delete key

Insert following code in JS file

function disableBackspace(evt, obj) {
    var charCode = (evt.which) ? evt.which : evt.keyCode
    if ((charCode == 8 || charCode == 46) && clientMaskcurr.length >=   obj.selectionEnd ) return false;
    return true;
}


Insert following code in HTML related input

PHP development with google App Engine (Implementing and Troubleshooting)

      Google App Engine lets you run web applications on Google's infrastructure. It is kind of a platform that you can build application from your preferred programming languages and run them on it.

   This post will discuss how to install App Engine in Linux environment and set it up to do PHP applications. Not much to do... But there will be some issues occur and here talk about how to troubleshoot them... 


[Following directory paths used as I preferred and you can use your own ;)]


Download Google App Engine  and put it in to a location where you preferred.
                [/opt/lib/google_appengine]

You can run your web applications with out doing any further things but it's easy adding this to your PATH variable in .bashrc ...
So insert following lines to .bashrc

# set GOOGLE_APP_ENGINE
export APPENGINE_SDK=/opt/lib/google_appengine  (Change this path to where downloaded app engine located)
export PATH=$PATH:$APPENGINE_SDK


After doing that change directory to where your .bashrc file locate. (home folder) Execute following command...
                   [root ~]~$: .bashrc       (This will reload new PATH you added)

Now execute command "dev_appserver.py", you can see usage parameters defined. If not some thing missing....So check what you have missed... :P

Now we ll create our HelloGoogle app from PHP and run it.

Create a directory in a workspace you preferred.
                  [root ~]~$: mkdir -p /home/zee/google/helloGoogle

Then create a PHP file helloGoogle.php and insert following code.

<?php
      echo 'Hello Google!!!';
?>

Another file you need to create app.yaml in your helloGoogle directory. Without this your application cannot run on App Engine server. (Not going to talk about it much as this is about implementing and troubleshooting) Insert Following code in to that file. 

application: helloGoogle
version: 1
runtime: php
api_version: 1

handlers:
- url: /.*
script: helloGoogle.php

Now you can continue..................


Execute following command in shell to up and run the server with your application...

         [root ~]~$: dev_appserver.py /home/zee/google/helloGoogle/

Go to your browser and load http://localhost:8080/ ... :)

Web 2 development with Yii (Implementation and configuration)

 

Yii.....High performance PHP framework that can use to create web applications easily. 

This topic will discuss how to install(implement) and configure Yii to use it more efficient way...
[As I'm an Ubuntu user I ll explain things only from linux ;) ]

I mentioned that this is an PHP based framework so again don't want to say, you must have PHP in your PC/Server to continue......  :P
