Solved : Android Library Projects Cannot Be Launched

Android library projects cannot be launched problem while running android application on eclipse. Following error message I got,

 

Error Message: Android library projects cannot be launched.

 

When I developed my first QuoteQuiz android app and tried to Run it, I got encountered with the given error. I again checked the code, build target, build path, library and everything were proper. I cleaned the project and Run again, but still this error occurred. I google for "Android library cannot be launched" problem and found the solution, this solved my problem.

 

Solution:

 

In Eclipse , Right Click on Project from Package Explorer

Select Properties,

Select Android from Properties pop up window,

See "Is Library" check box,

If it is checked then Unchecked "Is Library" check box.

Click Apply and than OK.
