The Jar file ../android-8/android.jar has no source attachment
<p>I came across this no source attachment problem when I was debugging the project, but when I run the android program without debugging enabled, the program would run without any trouble.  Even after I attached the jar file manually, it still reported that properties.class could not be found! What should I do with this problem? What is the reason for this? thanks!!!</p>
