In this tutorial I am going to describe JavaScriptInterface for calling JavaScript function from Android i.e., JavaScript Binding to Android.
I have written a blog post about : Calling JavaScript Function from Android and Handling Result
Setting up WebView
First add JavaScriptInterface to webView as follows. Here "MyAndroid" will be used later to call functions in JavaScriptInterface later.
Android WebView WebChromeClient example tutorial
WebChromeClient is used to handle a JavaScript events in Android App which are produced by WebView. The examples of such events are :
- onCloseWindow
- onProgressChanged
- onJsAlert
- onJsConfirm
- onJsPrompt
- onJsTimeout
Android WebView Complete Example Tutorial
The
In this tutorial I am going to demonstrate usage of WebView.
WebView
class allows you to display web pages as a part of your activity layout. WebView becomes helpful when your application frequently displays content from online resources.It simplifies task of performing a network request, parsing the data and rendering it in other Android layout. We can directly make HTTP request to an URL and load the returned HTML into WebView.In this tutorial I am going to demonstrate usage of WebView.
XSLT : Using reusable XSL to generate HTML Form dynamically
In this article , am going to describe how to generate html form dynamically using reusable xsl file.
Problem Statement :
Problem Statement :
Suppose I have large number of xml files : There is one condition that : there won't be any more nested tags . But the name of property tag will be different for each xmldata file.
First xml:
Xsl transform in Java working example (xml to html)
In order to display XML documents, it is necessary to have a mechanism to describe how the document should be displayed. One of these mechanisms is Cascading Style Sheets (CSS), but XSL (eXtensibleStylesheet Language) is the preferred style sheet language of XML.
XSL can be used to define how an XML file should be displayed by transforming the XML file into a format such as HTML, PDF, etc..

Java - Single instance of application - working source code example
Having a single instance of an application is crucial in most of the software. In this article, I am giving an example on how to implement single instance of an Application.
How it works :
How it works :
- New instance of application tries to connect to a specific ServerSocket (localhost, port#) to detect running applications. And a running application must have a ServerThread to detect possible run of new instance of the same application
- The main Logic in steps
- Find existing server socket running on localhost
- If found(another instance was already running) --> exit current instance of application
- else --
- start a new Server thread to detect run of future applications
- and start the application
Some useful Regular Expressions for Find/Replace in Eclipse IDE
Regular expressions is powerful tool mostly used in search, edit and manipulate text. A regular expression define a search pattern for strings. The abbreviation for regular expression is "regex".Regular expressions are used in several programming languages. But, unfortunately each language / program supports regex slightly different.
In this blog, I am going to explain the use of Regular Expression(regex) in Eclipse IDE. There are eleven examples in total.
