After doing some android coding, I’m supposedly doing some improvement on its user interface. But when I viewed the graphic layout of my main.xml, the black screen did not show up, instead, a message prompted me:
Eclipse is loading framework information and the layout library from the SDK folder. main.xml will refresh automatically once the process is finished.
I searched google but none of the solutions worked for me. Then I decided to reinstall the Android SDK. I removed it from my control panel and run the android-sdk installer I have (installer_r10-windows.exe). And that solves my problem. I hope this helps someone. :)
