After struggling with eclipse for overnight, I have made an android app named Test Hub. The app is pretty simple. You can practice or test HTML tags with it. It uses your phone's Webkit engine and result is displayed as you type.
I've also included a input method meant for web development. To activate the input method, go to "Settings > Language & Keyboard" and check the box next to "Test Hub". Now when in a text box, long touch the screen and choose "Input Method". Now choose "Test Hub" and now you can use the input method. The most used keys in web designing are easily accessible.
May not be a big success, but hope it will help some people.
Here are some more screenshots,
