Red exclamation mark over the project in eclipse
<p>I am trying to run a project but there is a red exclamation mark over the project name. When checked in Problems, its throwing an error "project is missing required library". The library is pointed to android.jar located in some path. When checked in package explorer, I found the android.jar in Android 2.3.1 folder structure of project in package explorer. The android.jar located in Android 2.3.1 folder is pointing to some other path. Is the build error occurring due to the difference in paths for android.jar files? I have imported the project.So, how should I modify the path which is shown in the problems window? I am newbie to android and so pls help me.</p>

<p>Thanks!!!</p>
