app wont run on android 2.3
<p>I have problem running my app on android 2.3. The app has splash screen and timer, then it runs
the main class. It works fine on android 2.2, 2.1 etc. It just crash on android 2.3. 
My question is, do i need to create another thread than the main activity thread.?</p>

<p>Thanks </p>

<p>here is the error below</p>
