Binding JavaScript code to Android code

by Sumeet Arora CTO,Evon Technologies

When Building a WebView based Web App in Android, you can communicate with your android client side code through your Javascript code.
You can call any method of Android client side code on any triggered event on JavaScript code.

For example, the following code will call the showAndroidDialog() in your Activity on an onClick event of a button in your JavaScript code.


androidjs.html

  1. <html>
  2. <head>
  3. <style>
  4. body{
  5. background-color: #FF0000;
  6. color:#fff;
  7. }
  8. input{
  9. background-color: #F7D358;
  10. padding:10px;
  11. color: #000;
  12. }
  13. div#content{
  14. padding:20px;
  15. background-color: #F7D358;
  16. color: #000;
  17. }
  18. </style>
  19. <script type="text/javascript">
  20.  function showAndroidDialogg(dialogmsg) {
  21.         Android.showAndroidDialog(dialogmsg);
  22. }
  23. </script>
  24. </head>
  25. <body>
  26. <center>
  27. <h3>Binding JavaScript code to Android code</h3>
  28. <div id="content">
  29. The following button will call the showAndroidDialog() in your Activity.
  30. </div>
  31. </br></br>
  32. <div>
  33. <input type="button" value="Trigger Dialog" onClick="showAndroidDialogg('This dialog is triggered by Javascript')" /><br/>
  34. </div>
  35. </center>
  36. </body>
  37. </html>
