The link goes nowhere...
Android based devices has a web browser installed with (and if not you can install one). So there is no problem using web application with HTML, CSS and JS. However you have to design you site to display well on different devices with different screen sizes and resolutions...

I have simple android project that inserts and retrieves some data from MySQL DB using PHP Scripts and JSONParser.
The Project is done using AsyncTask, when I press Insert button, the Progress Dialog Starts then after sometime it displays the message "Unfortunately 'App_Name' has stopped." in Eclipse Emulator.
I have done the following and many others....
*AndroidManifest.xml is set with all required(Permissions)
*I'm using URL_Insert="http://10.0.2.2/foldername/insert.php";
Do I need to configure WAMP Server.....?
Please tell me all possible causes of on button click crash from your experience.

Hello all,
I am very new to android development.I have installed AVD and JAVA SDK and able to run my test application on Simulator also.
(As mentioned in the below link)
https://sites.google.com/site/barbarahohensee/android-development-on-ubuntu
But the issue is:It takes a long time to run on simulator. I am on my way to develop very few basic pages with buttons and textBox and in last payment option. I dont want to run simulator every time I want to check GUI.
Please suggest.

Go for Genymotion Emulator For First Time It will take time to download After That It is Fast,
2)Go for original devices
|
|
|
|

It's true that the emulator load very slowly at the first time, but that's it. You can reuse it from then on...

Using a physical device to test your android app is another alternative.
