Ok finally I solved the problem using Denis Loh suggestion. Key to solve this problem is check the R file of all the included libraries, when this crash happens design library R is not generated and hence not shown in gen folder of your project.

But eclipse will not show you problem why it is not generated(God knows how eclipse work)

So in order to generate R file of design folder

In project.properties of design library set target to 21 or highest available

Clean v7 , design and your project run & enjoy

回答2:

You can import androidSupportDesign from \sdk\extras\android\support\design and tick "isLibrary", then you import appcombat_v7(lib) to androidSupportDesign. Final you import to your project and clean build all! I hope it can help

All project build with api > 21

you!

How I solve this problem is to run './gradlew clean' first, then try to compile the code with './gradlew installDebug'.

I guess the problem is due to the old R file still remain the same, and the compiler can't find resource related to CoordinatorLayout within the old R file.

May this help.
