I've been looking for a solution to enable tamil fonts in my android (HTC Magic). Finally I found a simple solution by doing a very simple config change in Opera Mini browser.
1. Download 'Opera Mini' from Android Market
2. Open Opera Mini
3. Open the configuration page by typing "config:" in the address bar and hit 'Go'
4. At the bottom of the page, you'll see an option 'Use bitmap fonts for complex scripts'. Select 'Yes' for this option
5. Save the change and restart your 'Opera Mini' browser.
Enjoy reading tamil on your Android
